BLS(basic life support) & ACLS with PALS by Dr. Shailendra

  1. BLS(BASIC LIFE SUPPORT) & ACLS(ADVANCED CARE LIFE SUPPORT) PRESENTER- DR SHAILENDRA DR VINOD CO-ORDINATOR- DR DEVANAND PAWAR
  2. WHAT IS CARDIAC ARREST • Cessation of normal circulation of blood due to failure of heart to contract effectively. • It is sudden cessation of mechanical activity of heart with some or no electrical activity.
  3. OHCA & IHCA • IHCA is in hospital cardiac arrest While • OHCA is out of hospital cardiac arrest
  4. HOW IT WORKS?
  5. Cardiac Arrest • Can be classified on the basis of ECG rhythm into- a. Shockable- 1. Ventricular fibrillation (VF) 2. Pulseless ventricular tachycardia (pulseless VT) a. Non-shockable- 1. Asystole 2. Pulseless electrical activity (PEA)
  6. Cardiac Arrest • Treatable causes of cardiac arrest- 5H’s 5T’s Hypoxia Thrombosis(coronary) Hypothermia Cardiac tamponade H+ less(acidosis) Tension pneumothorax Hyperkalemia Toxins Hypovolemia Thrombosis(pulmonary)
  7. Cardiac Arrest • Signs and symptoms- 1. No response 2. No breathing 3. No pulse
  8. Cardiac Arrest • Lack of carotid pulse is gold standard for diagnosis • Patient may present like unresponsive to tactile verbal stimuli with no or abnormal breathing or agonal gasps and absence of carotid pulsation.
  9. Rhythms In cardiac arrest ECG rhythms that can be seen in cardiac arrest are- • Ventricular fibrillation • Pulseless ventricular tachycardia • Pulseless electrical activity • asystole
  10. Ventricular fibrillation • Most important shockable cardiac arrest rhythm
  11. Ventricular fibrillation • Prolonged VF leads to decreasing amplitude of waveform, from initial coarse VF to fine VF progressively leading to asystole due to decreased myocardial energy stores
  12. Ventricular fibrillation • ECG findings- 1. Chaotic irregular deflections of varying amplitudes 2. NO identifiable P waves, QRS complexes OR T waves 3. Rate-150 to 500/min 4. Amplitude decreases with duration.
  13. Pulseless VT • ECG findings- o Very broad QRS (>160ms) o AV dissociation o Extreme axis deviation “northwest”, so QRS positive in Avr and negative in 1 and Avf
  14. PEA • Cardiac arrest in which ECG shows heart rhythm that should produce a pulse bt it does not. • Lack of palpable pulse in presence of organised cardiac electrical activity • Also known as “electromechanical dissociation”.
  15. Asystole • There is no discernible electrical activity on ECG monitor. • May get confused with flat line.
  16. CA management cont.. These can be achieved by- • CPR (Cardiopulmonary resuscitation) • Defibrillation • Medications • Therapeutic hypothermia
  17. What is BLS? • A level of medical care which is used for victims of life- threatening illnesses or injuries until they can be given full medical care at a hospital. It can be provided by trained medical personnel, including emergency medical technicians, paramedics, and by qualified bystanders.
  18. WHAT IS ACLS? • A set of clinical interventions for the urgent treatment of cardiac arrest, stroke and other life-threatening medical emergencies, as well as the knowledge and skills to deploy those interventions.
  19. What is CPR? • Cardiopulmonary Resuscitation • An emergency procedure which is series of actions performed until further measures are taken to restore Return of spontaneous blood circulation (ROSC) and breathing in a person having cardiac arrest.
  20. Pathophysiology CARDIAC ARREST No blood or tissue oxygenation Brain sustain damage for 4 min and after 7 min irreversible damage occurs After 1-2 hrs, cells of body die CPR Causes blood to circulate to brain and heart Enough blood to brain delaying brain death and allows heart to remain responsive till defibrillation
  21. Steps After recognition of arrest C Compressions A Managing airway B Rescue breathing
  22. Recognition Of Arrest
  23. RECOGNITION OF ARREST • First step is to Ensure scene safety • Check for response • Shout for help/activate resuscitation team at the time or after checking pulse and breathing • Activation of AED/emergency equipments either by lone rescuer or person sent by rescuer must occur as soon as possible after checking pulse and breathing (ideally should be done simultanously) • Immediately begin CPR and use AED/defib when available
  24. Check breathing? • Inspecting the chest rise of patient while palpating carotid pulse (saves time) • OR Lay rescuer can check by keeping our fingers in front of nostrils/keeping ears close to nose to check if any blow of expired air is present or not. • Agonal gasps or abnormal breathing patterns may get confused with normal respiration by lay man rescuer.
  25. Carotid Artery
  26. C P R • Start CPR immediately after checking and observing there is no 1. RESPONSIVENESS 2. BREATHING 3. PULSE
  27. Chest Compressions
  28. Chest Compressions • Technique- o Position yourself at patient’s side o firm, flat surface and o remove all the clothings o Put the heel of one hand on the centre of chest (sternum) at the level of nipples and put your other hand on the top of that hand.
  29. Chest Compression • Technique- o Lock all joints ; movement is allowed only at hip joint o Push hard and fast (100 - 120 times / min) o At the end of each compression, chest is allowed to recoil completely o Avoid excessive ventilation o Then give next compression immediately o This cycle should be repeated until patient revives or any EMS arrives.
  30. Chest Compressions • Rate- 100 to 120/min • Depth- 5 cms to 6 cms (2 inches to 2.4 inches) • While giving chest compression only resuscitation (COLS) by lay or untrained rescuer give chest compressions only • Ratio – 30:2 • Minimum/no interruptions
  31. Chest Compressions
  32. Mechanisms • Cardiac Pump – 1. Blood pumping is assured by compression of heart between sternum and spine 2. Between compressions, thoracic cage expands and heart gets filled with blood.
  33. Mechanisms • Thoracic pump – 1. Blood circulation restored due to changes in intra-thoracic pressure and jugular and subclavian vein valves. 2. During chest compressions,blood is directed from pulmonary circulation to systemic circulation.
  34. Thoracic Pump
  35. AIRWAY
  36. Head tilt-Chin lift
  37. Jaw Thrust
  38. Rescue Breath
  39. Rescue Breath • Each rescue breath over 1 second • Visible chest rise • 30 compression: 2 breaths (no advanced aiway) • Advanced airway- o Give 1 breath every 6 to 8 seconds without attempting to synchronise breaths between compressions o 8-10 breaths per min
  40. Types • Mouth to mouth breathing • Mouth to barrier device breathing • Mouth to nose and mouth to stoma ventilation • Ventilation with bag and mask • Ventilation with supraglottic airway • Ventilation with advanced airway
  41. Mouth-To-Mouth breath
  42. Mouth-To-Nose breath • Given when mouth cant be open • Good seal cant be made • Severe injury present over area of mouth
  43. Mouth-To-Barrier device
  44. Bag and Mask ventilation • Position yourself directly above patient’s head • E_C clamp technique followed o Perform head tilt o Make “C” with thumb and index finger of one hand o When we use 3 fingers, it forms “E” o Chest rise is checked while squeezing the bag to give breaths to the patient.
  45. Bag And Mask Ventilation
  46. CPR cont.. • Access airway and if patient is on ventilator or intubated and being ventilated with bag then give 1 breath every 6 seconds • There is no use of giving any extra breaths • ETCO2 monitoring – Can be used as a guide to monitor when ROSC occurs or is unlikely to occur. Successful outcome is unlikely if end tidal co2 is not higher than 10-15mmhg after 20 mins of CPR • ETCO2 monitoring should not be considered for ROSC access in non-intubated patients
  47. Defibrillation
  48. Defibrillation • Important in saving patient of cardiac arrest • Mechanism- A defibrillation shock must be strong enough to stun or excite a large majority of the cardiac tissue. If a sufficient portion of the cardiac tissue were made temporarily unexcitable by a shock, the uncoordinated wavefronts of excitation that perpetuate VF would be extinguished, and would allow normal cardiac excitation and contraction to resume.
  49. When to defibrillate? • Indications – o Ventricular fibrillation o Pulseless ventricular tachyardia • Contra-indications – o If the patient is having pulse (accidental shock during this phase may lead to arrhythmias ) o Unsafe situations for rescuer o Asystole o Pulseless Electrical Activity
  50. Types MONOPHASIC BIPHASIC Delivers current in one direction Delivers current in two direction Requires more energy upto 360J Requires less energy upto 200J Cuases more chest burn Cuases less chest burn More trauma Less trauma More myocardial damage Less myocardial damage First shock survival rate is around 60% First shock survival rate is around 90% Outcome is good Outcome is better than monophasic defibrillator
  51. Other types • Manual External Defibrillator • Manual Internal Defibrillator • Automated External Defibrillator • Semi-automated External Defibrillator • Implantable cardioverter-defibrillator • Wearable Cardiac Defibrillator
  52. • Continue Chest compresssions until defibrillator is available • Once the defibrillator is available, ask your assistant to attach paddles- Paddles may be 1. Handheld paddles :  Larger paddles size decrease transthoracic resistance increasing the energy delivery  Apply gel pads to help minimise burns and enhance proper contact  Pressure applied to chest with paddles decreases impedance and potentially improves efficacy of countershock  Pressure applied should be 25-30lbs or 11-12 kgs  Place paddles atleast 2 cms away from electrodes and 10cms away from pacemaker generator
  53. Defibrillation  Paddle placement :  Antero-Lateral Anterior pad on the right infraclavicular chest and lateral pad lateral to left chest at the level of nipple in midaxillary line  Antero-posterior Anterior pad on the right infraclavicular chest and posterior pad at left lower scapula (More preferred in atrial arrhythmias and in patients with implanted devices)
  54. Defibrillation 2. Self Adhesive Pads -  More common  Easy to use  Equally effective as handheld paddles  No gel required for contacts  Minimizes risk to providers as less contact with bed and patient during shock delivery
  55. • Once the paddles are attached , set the desired charge to be delivered usually 200 j in biphasic defibrillators. • Ensure there is no contact with metal on bed and all rescue personnel are away from the bed. Call “ALL CLEAR”. • Keeping paddles firm in positions press charge and deliver shock • Start CPR immediately after delivering shock, keeping pads in place to minimise time delay for next shock. • No delay is allowable • Check for any signs of revival after completion of one cycle of CPR • Stop if pulsations are felt/ sinus rhythm achieved/pt moves his or her limbs or starts to breath
  56. What is AED? • Automated External Defibrillator • A portable electronic device that automatically diagnose the life-threatening cardiac arrhythmias of ventricular defibrillation and pulseless VT and is able to treat them through defibrillation. • Possible for more people to respond to medical emergency where defibrillation is required • Can be used by lay-rescuer trained in CPR
  57. AEDs • Made part of emergency response program • Gives simple audio and visual commands,making its use easy • Should be available at public places like stations, stadiums, airports, malls etc. • Can’t be overriden manually and takes upto 10-20 sec to detect arrhythmias • Now a part of BLS program because early defibrillation is found to increase survival rate of patient
  58. AEDs
  59. AEDs • Semi-automated External Defibrillator- o Similar to AEDs bt these can be overriden and usually have ECG display o Ability to pace o Can be used by paramedics
  60. IV / IO Access
  61. IV /IO Access • Important to give emergency medications • Intravenous (IV) and Interosseous routes are approved • Chest compressions should not be stopped to have IV access • Should be easily accessible • If central venous catheter in place , prefer giving drugs through CVC • When 2 or more rescuers are present then one rescuer should continue giving chest compressions while others should attach defib and find iv access simulteneously
  62. IV / IO Access • Interosseous route – o is best to be taken in patient with severe burn , polytrauama patients , difficult IV access beacause of obesity , history of IV drug abuse o Rapid and safe method o Needs expertise o When failure to access peripheral IV line placement o Added in AHA guidelines 2005 of Cardiopulmonary resuscitation
  63. IV / IO Access o May need pressure bags o Contraindications for IO access  Skin infection at the site of insertion  Fractured bone  Disorders of bone (osteoporosis, osteomyelitis, osteogenesis imperfecta)  Localised cellulitis  Recent failed attempt in same bone
  64. IV / IO Access • Best sites for IO access – o Proximal tibia (2cm below tibial tuberosity) o Distal tibia (2cm above medial malleolus) o Proximal humerus (Greater tubercle near coracoid process) o Sternum has relatively thin medullary cavity so avoided because of risk of transpassing through bone causing injury to structures below sternum
  65. Advanced Airway
  66. Advanced Airway • Accessible in IHCA • Oropharyngeal Airway – o Used in unconscious cases where head tilt – chin lift and jaw thrust maneuvers fail to provide and maintain unobstructed airway o Should not be used in conscious / semiconscious patients o Used to open airway for proper ventilation , suctioning , can be used like a bite block in intubated patient .
  67. Advanced Airway • Nasopharyngeal Airway – o May be used in conscious , semiconscious or unconscious patients o Where OPA placement is difficult (gag reflex, trismus , massive trauma , wiring of jaws) o Patient’s smallest finger or outer diameter of NPA compared with nostrils can be used a guide to select proper size o Length – tip of nase to earlobe
  68. Advanced Airway • Advanced Airway equipments used to provide ventilation are – o Laryngeal Mask Airway (LMA) o Endotracheal Tube (ETT) o Laryngeal Tube (LT) o Combitube
  69. LMA • Can be used as a conduit to ETT for emergency airway
  70. LMA • Insertion Technique – o Tightly deflated against flat surface (spoon shape) o Position of patient – morning sniffing position o Lubricated with water based jelly on its posterior surface o Pressed along the palato-pharyngeal curve using the index finger. o Once the give away is felt , It is finally pushed further down till resistance is felt. o Cuff is then inflated according to the size of LMA , Proper insertion is checked with visible chest rise and air entry
  71. ETT
  72. ETT • Technique of insertion – o Fully deflate the cuff o Patient position – morning sniffing o Gentle direct laryngoscopy done by deflacting tongue to one side and lifting the base of epiglottis o Once the vocal cords visible , pass appropriate sized ETT through the cords o Inflate the ETT cuff and check visible chest rise and air entry
  73. Laryngeal Tube
  74. Laryngeal Tube • Insertion technique – o Choose the appropriate size King LT airway based on the patient’s height. o Inflate and test the cuff for integrity then lubricate only the posterior portion of the tube. o Maintain the head tilt chin lift or modified jaw thrust if appropriate. o Insert the King LT laterally into the corner of the mouth. o Advance the tip of the tube under the base of the tongue, while rotating the tube back towards the midline. o Advance the tube until the base of the connector is aligned with the teeth or gums. o Inflate both the cuffs and check for visible chest rise and air entry
  75. Combi-tube
  76. Suctioning • Essential component to maintaining patient’s airway by clearing secretions • Soft and flexible catheters used for mouth / nose / ETT • Rigid catheters like Yankauer used for oropharynx having thick secretions , particulate matter
  77. Monitoring • Done with standard monitors attached to the patient – o Pulse Oximeter o ECG o NIBP o ETCO2 o Central Venous O2 Saturation
  78. Monitoring • Pulse oximetry – o To continously monitor oxygen saturation during and after the period of resuscitation o Monitors adequate oxygen delivery and ventilation o Continous pulse rate monitoring • ECG – o Monitors continously the electrical activity of heart o Detection of arrival of normal sinus rhythm after resuscitation o Detection of arrhythmia during or after post-resuscitation period o Continous heart rate monitoring
  79. Monitoring • ETCO2 – o Useful in intubated patients only (patients with advanced airway ventilation) o Measures exhaled gas at the end of expiration o Measure of balance between ventilation and perfusion in lungs (V/Q balance) o Varied in directly with changes in cardiac output relative to ventilation o When alveolar ventilation is constant , ETCO2 changes directly proportional to CO
  80. Monitoring • ETCO2 – o Normal range – 35 to 45 mmhg o Serial measurements during CPR used to identify when ROSC occurs or is unlikely to occur o Patients achieving ROSC during CPR show progressive increase in ETCO2 value while progressive declining ETCO2 in those who don’t achieve ROSC o Successful outcome is unlikely if ETCO2 is not higher than 10 to 15 mmhg after 20 mins of CPR
  81. Monitoring • Central Venous O2 Saturation (scvO2)– o Measure of balance between systemic O2 delivery and systemic O2 uptake o Normal range – 70 to 80 % o Failure to achieve the scvO2 more than or equal to 30% during CPR is associated with failure to achieve ROSC
  82. Medications
  83. Medications • Now only adrenaline/epinephrine and amiodarone are approved as drugs useful in ACLS • Atropine and vasopressin are not recommanded for the use in ACLS as per 2015 guidelines by AHA • Vasopressin was included till 2015 guidelines bt studies have shown that there is no useful evidence of vasopressin used in conjunction with adrenaline in survival of patient
  84. Adrenaline • Sympathomimetic agent • Alpha and beta adrenergic action having approximately equal activity on both receptors • Dose - IV boluses of 1 mg followed by 10-20cc of normal saline to flush as a standard dosing regimen repeated every 3-5 min as required • Previously it was thought that higher dose epinephrine will be better if standard 1mg dose doesn’t produce desirable effect bt now higher dose epinephrine is not recomended as it is shown not to improve survival rate rather causes more chances of dysrhythmias
  85. Adrenaline • Positive ionotrope and positive chronotrope causing increased cardiac output, increased oxygen consumption and coronary blood flow • Increases peripheral vascular resistance causing increase in systolic blood pressure more than diastolic BP • It is mainly used because of its action on beta adrenergic effects causing vasoconstriction which increases cerebral and coronary blood flow increasing MAP and aortic diastolic pressure
  86. Adrenaline • Indications – 1. Cardiac arrest from VF 2. Pulseless VT unresponsive to initial counter shock 3. Asystole 4. PEA 5. Profoundly symptomatic bradycardia
  87. Adrenaline • Precautions – o Should not be added to infusions that contain alkaline solutions o Can exacerbate ischemia and induce ventricular ectopy
  88. Amiodarone • A complex antiarrhythmic agent with – o Effect on Na+, K+ and Ca++ channels o Beta and Alpha adrenergic blocking properties • Alters conduction through accessory pathways • Class 3 antiarrhythmic agent • Has direct action in isolated myocardial preperations to decrease delayed slow outward K+ current and in higher doses additionally decreases fast and slow inward currents due to Na+ and Ca++ respectively
  89. Amiodarone • Indications- o Pharmacological conversion of Afib o Persistent vt/vf after defibrillation and adrenaline o Hemodynamically stable VT o Hemodynamically stable polymorphic VT o Hemodynamically stable wide-complex tachycardia of uncertain origin
  90. Amiodarone • Indications- o Control of rapid ventricular rate in pre-excitation SVT due to accessory pathway conduction o AN adjunct to electrical cadioversion of reftractory PSVTs/ atrial tachycardias o Control of ventricular rate in SVTs with severely impaired LV function when digitalis has proved ineffective
  91. Amiodarone • Adverse Effects – o Hypotension o Bradycardia These are the most significant adverse effects of amiodarone so have to be given consciously and selectively o Causes QT prolongation (Incidence of torsades de pointes and other proarrhythmic complications are rare with amiodarone) o Exacerbation of CHF (d/to negative ionotropic affect) o Phlebitis (When administered through peripheral line), so better to administer via central venous catheter o Hepatitis, Hypo/hyperthyroidism, pneumonitis, neuropathy and tremors
  92. Amiodarone • Dosage- o In VF/VT - 300mg bolus followed by 1mg/min for first 6 hours then 0.5mg/hr for next 18 hrs o Additional 150mg boluses can be given for breakthrough arrhythmias upto a total load of approximately 2g/24hrs and 5-8gm total o Can be loaded orally (800-1600mg daily for 2-3wks with maintainance dose of 400mg daily for ventricular arrhythmias)
  93. Lidocaine • Can be used in ACLS when amiodarone is not availabale • Mechanism – It suppresses automaticity of conduction tissue in heart, by increasing the electrical stimulation threshold of the ventricles, purkinje fibres, and causes spontaneous depolarisation of ventricles during diastole by direct action on the tissues
  94. Lidocaine • Dosage – 1 to 1.5 mg/kg IV/IO as a first dose then 0.5 to 0.75 mg/kg IV/IO at 5-10 min intervals ; to a maximum of upto 3mg/kg • It blocks permeability of neuronal membrane to sodium ions causing blockade of depolarisation and blockade of conduction
  95. MgSo4 • MgSo4 should be considered for torsades de pointes associated with long QT interval • It can be classified as Na+/K+ pump agonist • Mechanism – It suppresses several atrial calcium channels and ventricular after-polarisation • Its routine use in Cardiac Arrest is not recommended unless torsades de pointes is present
  96. Newer CPR Devices
  97. Newer CPR device • Manual – o Cardiopump o CPR RsQ assist o CPR PRO cradle o Lifebelt o Lifestick
  98. Newer CPR Devices • Electric – o Autopulse o Lifeline ARM o LUCAS etc o EM CPR • Pneumatic – o Thumper o Lifestat o Hydraulic-pneumatic band
  99. Cardiopump
  100. Cardiopump • Handheld device • Piston having a suction cup that sticks to patient’s chest • Manual form of CPR device • Operator operates the device by hand • Alternate compression with active decompression increases venous return by decreasing intrathoracic pressure and increases overall flow
  101. CPR RsQ assist
  102. CPR RsQ assist • Light and compact • It has a handle which provides support for active compression during CPR • Manual device, operated by rescuer
  103. CPR PRO cradle
  104. CPR PRO cradle • Manual device • Have to be operated by rescuer • Can be used for compression only because there is no decompression
  105. Lifebelt
  106. Lifebelt • Manual device • For compression only, no decompression • A provided levarage is pushed against the chest
  107. Life-stick
  108. Lifestick • Manual device • Dual handled rigid bar with two short pistons with adhesive pads • Performs an interposed abdominal compression cardiopulmonary resuscitation (IAC-CPR) that is abdominal compression alternated with chest compressions • This cyclic compressions doubles the flow and allows to decrease depth of compression and decrease injury to sternum and ribs • Compressions should be less vigorous so as to prevent any injury to vital organs • So it requires lower compression rates because of its double pumping effect and danger to injure the abdomen
  109. Autopulse
  110. Autopulse • Electricaly operated • Consists of a load distributing band and a backboard • The band is placed around the chest and tightened and loosened by the motor • It has a fixed compression rate of 80/min because it has a greater effect on hemodynamics at lower compression rates
  111. LUCAS
  112. LUCAS • Electrically operated • Piston mounted on a removable frame placed around the chest • The frame is fixed on a rigid backboard • It provides alternate compression with active decompression by a suction cup that forces thorax back to its uncompressed volume (recoil)
  113. EM-CPR • Electrically operated • Do not exert any force on thorax • Stimulates contraction of both abdominal muscles and diaphragm by magnetic impulses generated by coils and such a rhythmic contraction of abdominal muscles pump blood from abdomen which contains 20-25% of the total blood • It also provides negative pressure ventilation with this mechanism which aids in circulatory output
  114. Thumper
  115. Thumper • Pneumatically operated • It has piston mounted on a arm fixed on a supporting column • Rigiod backboard • It gives compressions with the rate of 100 compressions per min
  116. When to stop CPR? • A general approach is to stop CPR after 20 minutes if there is no ROSC or viable cardiac rhythm re- established, and no reversible factors present that would potentially alter outcome.
  117. • Reasons to cease CPR generally include: o ROSC - Resuscitation guidelines require 2 min of CPR post defibrillation prior to checking for ROSC; may be identified by an upsurge in ETCO2 o Pre-existing chronic illness preventing meaningful recovery ie. nursing home resident with dementia, disseminated cancer o Acute illness preventing recovery ie. 100% burns, non-survivable injuries, catastrophic TBI with no brain stem reflexes o No response to ACLS after 20min of efficient resuscitation in absence of ROSC, a shockable rhythm or reversible causes
  118. • In the pre-hospital setting a validated rule has been described : Stop CPR if: o No return of spontaneous circulation o No shocks are administered, and o The arrest is not witnessed by emergency medical-services personnel • Otherwise, the rule recommends transportation to the hospital, in accordance with routine practice
  119. • Other special situations: o In a newly born baby with no detectable heart rate that remains undetectable for 10 minutes, it is appropriate to consider stopping resuscitation o Traumatic arrest (perform emergency thoracotomy if appropriate; closed-chest CPR is ineffective) o When rescuers are exhausted (in the prehospital setting) o If the patient is irrefutably dead!! (e.g. rigor mortis, decomposition, hemisection, decapitation)
  120. P.A.L.S.
  121. PALS • It is pediatric advanced life support • For pediatric 1. Cardiac arrest 2. Bradyarrythmias 3. Tachyarrhytmias etc
  122. PALS • Pediatric CPR is followed with 1-rescuer and 2- rescuer guidelines • Start with chest compressions as soon as cardiac arrest is detected (no responsiveness, no breathing and no pulse) • Chest compressions – o For children – 1.5 inches to 2 inches deep o Once the child reaches puberty we can give 2 inches to 2.4 inches deep compressions same like adult guidelines o For 1-rescuer –ratio of 30:2 (30 compressions: 2 rescue breath) o For 2- rescuer – ratio of 15:2 o Compression rate should be 100-120/min
  123. PALS • Mouth to mouth or mouth to nose breathing can be given after perfoming chin lift head tilt or jaw thrust giving 1 breath every 3-5 seconds with a goal of 12-20 breaths per minute • Bag and Mask ventilation is always batter and commonly used in IHCA (In Hospital Cardiac Arrest) • There is no role of atropine prior to intubation to avoid bradycardia • Once the AED is available, attach paddles immediately and simulteneously continue compressions with minimum/no interruptions
  124. PALS • After giving 2 breaths, immediately give 30 compressions. The lone rescuer should continue this cycle of 30 compressions and 2 breaths for approximately 2 minutes (about 5 cycles) before leaving the victim to activate the emergency response system and obtain an automated external defibrillator (AED) if available
  125. PALS • When child is intubated then give 1 breath every 6 seconds • Goal in intubated children is to maintain breathing rate of 10 breaths per min • Defibrillation in pediatric ALS- o 1ST SHOCK – upto 2 joules per kg o 2ND SHOCK – upto 4 joules per kg o SUBSEQUENT SHOCKS – should be more than 4 joules per kg , maximum upto 10 joules per kg
  126. Medications in PALS
  127. DRUGS IN PALS • Adrenaline – o Dose - 0.01mg/kg o Repeated every 3-5 mins o Can be given via endotracheat route with a dose of 0.1 mg/kg • Amiodarone – o Dose - 5mg per kg during cardiac arrest o May repeat 2 times in case of refractory VF or pulseless VT
  128. DRUGS IN PALS • Lignocaine – o Loading dose : 1mg per kg o Maintainance dose : 20-50 micgm per kg per min infusion o Can repeat bolus dose if infusion started more than 15 mins after the loading dose
  129. PREGNANCY & CPR • In pregnant woman, because of gravid uterus and IVC compression, enough venous return is not achieved so CPR with 2 – rescuers is recommanded with one rescuer pushing the uterus to the left side s and 2nd rescuer to give chest compressions • Patient should on a flat surface or if IHCA situation and table can be tilted then slight leftward tilt can be allowable • Compression rate – 30 compressions: 2 breaths
  130. Pregnancy & CPR • Risk of aspiration of gastric content more • Advanced airway management can be used if available which reduces risk of aspiration • Emergency C-section should be done
