Simple logic breathing problem supply rescue breathing.

1. Poisons (drugs) did not magically change their chemical structure and
start causing death by cardiac arrest. Drug OD is acute respiratory
failure. Our diaphragm still controls our breathing, adult needs 1.5
liters of air every 5 seconds. Naloxone is second line defense because
it does not always work and every second you withhold the air from
any respiratory patient every cell, tissue and organ is dying lack of
oxygen, especially the brain. Note massive doses Naloxone used, and
continuous respiratory assist. Rescue breathing lay responder same.
