CH 6. pt 2 Respiratory Emergencies Flashcards
2 ways respiratory emergencies can happen
- respiratory becomes difficult or ineffective (respiratory distress)
- respiration stops entirely (respiratory arrest)
for respiration to occur there must be…(4)
- an open passage to the lungs
- lungs must have sufficient oxygen
- gas exchange must occur
- lungs must inflate and deflate with effective rhythm
average respiratory rate of adult, child, infant
adult (12-20)
child (16-24)
infant (30-40)
normal quality of breathing
quiet, regular & effortless
how long without oxygen until clinical death p\takes place?
when heart stops pumping blood, 0-4min (reversible death)
how long until biological death takes place?
organs and brain stop functioning (4+min)
how long w/o oxygen does brain damage possible
4-6 min
how long w/o oxygen until brain damage is likely
6-10min
how long w/o oxygen until brain damage is certain
10+ min. Irreversible death
define hypoxia
insufficient oxygen reaches the cells
S/S of hypoxia
cyanosis
increase RR & HR
restlessness
decreased LOR
Dizzy/lightheadedness
define anoxia
condition with a total lack of oxygen
define eupnea, apnea, dyspnea
eupnea- normal respirations
apnea- cessation of breathing
dyspnea- difficult/laboured breathing including SOB
define respiratory distress
condition where breathing is difficult
define respiratory arrest
condition where breathing has stopped.
-rescue breathing is needed
S/S of respiratory emergencies (7)
-dyspnea
-abnormal breathing sounds
-abnormal breathing rate
-abnormal skin characteristics
-emotional effects (anxious/restless)
-neurological effects (dizzy/light headed)
-patient position (patient is in unusual position/tripod)
causes of respiratory emergencies (9)
trauma (c spine, head, chest)
inhaled toxins (drug overdoses)
low oxygen environment
airway obstruction
neurological injuries/conditions
poor circulation
lung infection
excess fluid in lungs
illness (COPD, emphysema, heart attacks, congestive heart failure)
places where there would be a lack of O2 (3)
- environmental- altitude
- O2 displacement by other gases- carbon monoxide
- O2 consumption- confined spaces
types of airway obstructions (3)
-tongue
-swollen airway
-foreign body obstruction (food, teeth, mouth guard..)
what to do with a partial airway & complete blocked airway
partial- encourage them to keep coughing. They will wheeze and cough. Narrowing of airway.
complete- unable to speak, breath or cough. No air exchange, make a high pitched noise. Caused by forgien body obstruction
what parts of the c spine keeps you breathing (responsible for diaphragm)
C 3, 4, 5
define anaphylaxis
severe allergic reaction that causes the air passage to constrict
what happens during anaphylaxis (4)
- less O2 is coming in due to swollen airway
- blood vessels dilate
- profound low BP
- cardiac collapse
what does an epi pen contain
epinephrine hydrochloride
slows the harmful effects of anaphylaxis
