Emergency Oxygen
Administration
Life threatening medical emergencies are usually
accompanied by low tissue oxygen levels (not enough oxygen to tissue and organs). If this progresses, the
brain will begin to die first, with other organs following. Additionally, low oxygen levels to the heart may
lead to respiratory arrest ( breathing stops), cardiac arrest (heart stops) and eventually irreversible brain
damage.
Supplemental oxygen is a
critical step in treating a severe or life-threatening illness or injury.
Emergency oxygen administration to a breathing
victim may PREVENT deterioration of the victim's condition that could lead to respiratory and/or cardiac
arrest. You won't have to work so hard doing CPR
and the victim will be most grateful!
When we
inhale, we breath approximately 21% oxygen from the atmosphere, normally we use about 5% of that oxygen in
respiration. When we exhale, 16% (the unused portion of oxygen) leaves our lungs through our airway. This unused
portion of oxygen can be used for rescue breathing.
In
OSHA’s Confined Space Standard, any
oxygen level below 19.5% is considered an oxygen deficient atmosphere and an air supplied respirator must be
used. Doesn't it make sense that a higher oxygen concentration during rescue breathing would get better
results?
When emergency oxygen is used with rescue breathing, the provider is administering 50% to 100%
oxygen when it is needed most.
Emergency Oxygen Administration quick facts
An injured or ill person can
benefit greatly from receiving air with a higher oxygen concentration. Without adequate oxygen, hypoxia, a condition in which
insufficient oxygen reaches the cells, will occur.
Signs and symptoms of hypoxia
include
· Increased breathing and heart rate.
· Changes in level of consciousness.
· Restlessness.
· Cyanosis (bluish lips and nail beds).
· Chest pain
· Always provide emergency oxygen to a victim having difficulty
breathing if it is available & you are trained to use it.
Emergency oxygen should be considered
if
· An adult is breathing fewer than 12 breaths per minute or
more than 20 breaths per minute.
· A child is breathing fewer than 15 breaths per minute or more
than 30 breaths per minute.
· An infant is breathing fewer than 25 breaths per minute or
more than 50 breaths per minute.
