Medical & nursing directors :
co-responsibility for ICU management
• a team approach :
doctors, nurses, R/T, pharmacist
• use of standard, protocol, guideline
consistent approach to all issues
• dedication to coordination and communication
for all aspects of ICU management
• emphasis on research, education, ethical
issues, patient advocacy

22Prof. Dr. R S Mehta, BPKIHS
24. Open Units
Definition :
any attending physician with hospital
admitting privileges can be the physician of
record and direct ICU care. (All other
physicians are consultants)
Disadvantage :
lack of a cohesive plan
Inconsistent night coverage
Duplication of services
24Prof. Dr. R S Mehta, BPKIHS
25. Closed Units
Definition:
An intensivist is the physician of record for
ICU patients. (other physicians are
consultants), All orders & procedures carried
out by ICU staff
• advantage:
• improved efficiency
• standardized protocol for care
• disadvantage:
• potential to lock out private physician
• increase physician conflict
25Prof. Dr. R S Mehta, BPKIHS
26. Transitional Units
Definition:
intensives are locally present shared co-
managed care between ICU staff and private
physician
ICU staff is a final common pathway for orders
and procedures
Advantage:
reduce physician conflict, standard policies and
procedures usually present
Disadvantage:
confusion and conflict regarding final authority &
responsibilities for patient care decision
26Prof. Dr. R S Mehta, BPKIHS
27. ICU Model Care
Full-time intensivist model :
patient care is provided by an intensivist
Consultant intensivist model :
an intensivist consults for another physician to
coordinate or assist in critical care, but dose not
have primary responsibility for care
Multiple consultant model:
multiple specialists are involved in the patient care,
(esp. R/T doctors for ventilators), but none is
designated especially as the consultant intensivist
Single physician model :
primary physician provides all ICU care
27Prof. Dr. R S Mehta, BPKIHS
28. A Good ICU
Well organized
trust

32. NURSING ASSESSMENT
IT IS THE FIRST STAGE OF NURSING
PROCESS IN WHICH THE NURSE
SHOULD CARRY OUT A COMPLETE
AND HOLISTIC NURSING ASSESS-
MENT OF EVERY PATIENT’S NEEDS,
REGARDLESS OF THE REASON FOR
THE ENCOUNTER.
32Prof. Dr. R S Mehta, BPKIHS
33. COMPONENTS OF
NURSING ASSESSMENT
1. NURSING HISTORY: Taking a nursing history prior to
the physical examination allows a nurse to establish a
rapport with the patient and family.
Elements of the history include –
Health Status
Cause of present illness including symptoms
Current management of illness
Past medical history including family’s medical history
33Prof. Dr. R S Mehta, BPKIHS
34. Social history
Perception of illness
2. Psychological and Social Examination-
Client’s perception
Emotional health
Physical health
Spiritual health
Intellectual health
3. Physical Examination : A nursing assessment
includes physical examination, where the
observation or measurement of signs, which can
be observed or measured, or symptoms such as
nausea or vertigo, which can be felt by the patient.
34
35. The techniques used may include Inspection,
Palpation, auscultation and Percussion in
addition to the vital signs like temperature, pulse,
respiration , BP and further examination of the
body systems such as the cardiovascular or
musculoskeletal systems.
Documentation of Assessment: The
Assessment is documented in the patient’s
medical or nursing records, which may be on
paper or as part of the electronic medical record
which can be assessed by all members of the
health care team.

47. PRINCIPLES OF CRITICAL
CARE NURSING
ANTICIPATION : The first
principle in critical care is Anticipation.
One has to recognize the high risk
patients and anticipate the requirements,
complications and be prepared to meet
any emergency. Unit is properly
organized in which all necessary
equipments and supplies are mandatory
for smooth running of the unit.
47Prof. Dr. R S Mehta, BPKIHS
48. EARLY DETECTION AND
PROMPT ACTION :
The prognosis of the patient depends on
the early detection of variation, prompt
and appropriate action to prevent or
combat complication. Monitoring of
cardiac respiratory function is of prime
importance in assessment.
Prof. Dr. R S Mehta, BPKIHS 48
49. COLLABORATIVE PRACTICE :
Critical Care, which has originated as technical
sub-specialized body of knowledge has evolved
into a comprehensive discipline requiring a very
specialized body of knowledge for the physicians
and nurses working in the critical care unit fosters
a partnerships for decision making and ensures
quality and compassionate patient care.
Collaborate practice is more and more warranted
for critical care more than in any other field.
49Prof. Dr. R S Mehta, BPKIHS
50. COMMUNICATION :
Intra professional, inter departmental and
inter personal communication has a
significant importance in the smooth
running of unit. Collaborative practice of
communication model
Prof. Dr. R S Mehta, BPKIHS 50
51. Prevention of Infection : Nosocomial
infection cost a lot in the health care services.
Critically ill patients requiring intensive care are at
a greater risk than other patients due to the
immunocompromised state with the antibiotic
usage and stress, invasive lines, mechanical
ventilators, prolonged stay and severity of illness
and environment of the critical unit itself.
51Prof. Dr. R S Mehta, BPKIHS
52. Crisis Intervention and Stress
Reduction : partnerships are formulated
during crisis. Bonds between nurses,
patients and families are stronger during
hospitalization. As patient advocates,
nurses assist the patient to express fear
and identify their grieving patttern and
provide avenues for positive coping.
52Prof. Dr. R S Mehta, BPKIHS
53. ORGANIZATION OF ICU
DESIGN OF ICU :
1. Should be at a geographically distinct area
within the hospital, with controlled access.
2. There should be a single entry and exit.
However, it is required to have emergency exit
points in case of emergency and disaster.
3. There should not be any through traffic of
goods or hospital staff. Supply and professional
traffic should be separated from public/visitor
traffic. 53Prof. Dr. R S Mehta, BPKIHS
54. 4. Safe, easy, fast transport of a critically sick pt
should be a priority in planning its location.
Therefore, the ICU should be located in close
proximity or ER, OT, trauma ward etc.
5. Corridors, lifts and ramps should be spacious
enough to provide easy movement of bed/trolley
of a critically sick patient.
6. Close, easy proximity is also desirable to
diagnostic facilities, blood bank, pharmacy etc.
BED STRENGTH:
1. It is recommended that total bed strength in ICU
should be between 8-12 and not less than 6 or
not more than 24 in any case.
54Prof. Dr. R S Mehta, BPKIHS
55. 2. 3-5 beds per 100 hospital beds for a Level III ICU
or 2 to 20% of the total no of hospital beds.
3. 1 isolation bed for every ICU beds.
BED AND ITS SPACE:
1. 150-200 sq.ft per open bed with 8 ft in between
beds.
2. 225-250 sq.ft per bed if in a single room.
3. Beds should be adjustable, no head board, with
side rails and wheels.
4. Keep bed 2 ft away from head wall.
55Prof. Dr. R S Mehta, BPKIHS
56. ACCESSORIES:
1. 3 O2 outlets, 3 suction outlets (gastric, tracheal
and underwater seal), 2 compressed air outlets
and 16 power outlets per bed.
2. Storage by each bedside.
3. Hand rinse solution by each bedside.
4. Equipment shelf at the head end.
5. Hooks and devices to hang infusions/ blood
bags, extended from the ceiling with a sliding rail
to position.
6. Infusion pumps to be mounted on stand or poles.
7. Level II ICUs may require multi channel invasive
monitors. 56Prof. Dr. R S Mehta, BPKIHS
57. 8. ventilators, infusion pumps, portable X ray unit,
fluid and bed warmers, portable light,
defibrillators, anaesthesia machines and difficult
airway management equipments are necessary.
STAFFING :
1. Medical Staff – the best senior medical staff to
be appointed as an Intensive Care Director or
Intensivist. Less preferred are other specialists
from anaesthesia / medicine who has clinical
commitment elsewhere. Junior staff are intensive
care trainers and trainees on deputation from
other disciplines.
2. Nursing staff – The major teaching tertiary care
ICU requires trained nurses in critical care. 57
58. The no of nurses ideally required for such unit is
1:1 ratio, however it might not be possible to have
such members in our set up. So 1 nurse for 2
patients is acceptable. The no of trained nurses
should also be worked out by the type of ICU, the
workload and work statistics and type of patient
load.
3.Allied Services – Respiratory services,
Nutritionist, Physiotherapist, Biomedical engineer,
technicians, computer programmer, clinical
pharmacist, social worker / counsellor and other
support staff, guards and grade IV workers.

74. Admission Criteria in ICU
The ICU admission decision may be based on
several models utilizing prioritization, diagnosis,
and objective parameters models.
A. Prioritization Model
This system defines those that will benefit most
from the ICU (Priority 1) to those that will not
benefit at all (Priority 4) from ICU admission.
74Prof. Dr. R S Mehta, BPKIHS
75. Priority 1:
These are critically ill, unstable patients in need of
intensive treatment and monitoring that cannot be
provided outside of the ICU. Usually, these
treatments include ventilator support, continuous
vasoactive drug infusions. Examples of these patients
may include post-operative or acute respiratory
failure patients requiring mechanical ventilatory
support and shock or hemodynamically unstable
patients receiving invasive monitoring and/or
vasoactive drugs.
Prof. Dr. R S Mehta, BPKIHS 75
76. Priority 2:
These patients require intensive monitoring
and may potentially need immediate
intervention. Examples include patients with
chronic comorbid conditions who develop
acute severe medical or surgical illness.
Prof. Dr. R S Mehta, BPKIHS 76
77. Priority 3: These unstable patients are critically
ill but have a reduced likelihood of recovery
because of underlying disease or nature of their
acute illness. Examples include patients with
metastatic malignancy complicated by infection,
cardiac tamponade, or airway obstruction.
Priority 4: These are patients who are generally
not appropriate for ICU admission. Admission of
these patients should be on an individual basis,
under unusual circumstances and at the
discretion of the ICU Director. These patients
can be placed in the following categories:
77Prof. Dr. R S Mehta, BPKIHS
78. B. Diagnosis Model
This model uses specific conditions or
diseases to determine appropriateness of
ICU admission.

82. Team of Critical Care Unit
Physicians.
The Most Responsible Physician (MRP) is the physician in charge of the patient’s
care during the current hospitalization. He or she communicates with other members
of the team on a daily basis.
Nurses
Intensive Care nurses are the minute-to-minute critical care providers. They not only
help to provide, but also coordinate most aspects of care delivery. They have received
specialized training in caring for critically ill patients.
Respiratory Therapists
Respiratory therapists have special training and experience in caring for patients with
breathing problems. They work closely with the physician to develop a plan to
support a patient’s breathing. They set up, monitor and maintain the breathing
machines (mechanical ventilators), and they adjust these machines minute by minute
and hour by hour to best meet the patient's needs.
82
83. Pharmacists
Pharmacists consult with the physician in selecting the right
medicines at the correct dose for patients and also in monitoring
drug levels in the body. Pharmacists also help to decrease
medication side effects and provide valuable information to the team
members.
Physical Therapist
They help prevent disabilities and facilitate rehabilitation as soon as
possible.
Dieticians
Dieticians calculate the nutritional needs of the critically ill patient
and consult with the physician to provide the patient with the best
possible diet, whether orally or through a feeding tube.
Medical Radiation Technologist
Medical Laboratory Technologist
83Prof. Dr. R S Mehta, BPKIHS
84. Trauma Coordinator
The Trauma Coordinator reviews the plan of care for each trauma patient and in
consultation with the ICU Care Team, makes suggestions regarding patient needs.
She also works closely with the patient and family, and provides teaching and
information to the patient and family about the patient’s progress and expected
outcomes.
Social Worker
Social workers provide professional assistance with the needs of patients and families.
They can help to assess and determine what resources patients and families might be
lacking, providing them with information on agencies to assist with various needs
and generally assisting with other family difficulties.
Clinical Educator
Clinical Educators are nurses who provide ongoing education for ICU nurses on new
practices, protocols and on new equipment. They are up-to-date with the best
practices in ICU and communicate with the Manager and with ICU nurses about all
aspects of nursing practice and education. As an important part of their role, they
provide a comprehensive orientation to nurses new to the ICU Care Team as well as
providing continuing advice, support and education for all nurses in ICU.
84
85. Ward Clerk
ICU Ward Clerks help with communication by answering the phones,
processing physician orders and coordinating some of the patient activities
in the ICU.
Pastoral Care
Chaplains are available to minister to the spiritual needs of patients and
families.
Manager
Nurse Managers are nurses with additional experience and education, who
are responsible for the day to day operations of the ICU. In addition to
managing the ICU nursing staff, the ICU Nurse Manager is responsible for
the ICU budget and nursing practices. Nurse Managers are responsible for
ensuring that the care in the ICU is safe. She/he hires ICU nurses and
ensures that all nursing staff members meet the standards established for
their performance. She is also there to assist family members with their
needs.
