Airway Management Flashcards
Physical act of air moving into & out of the lungs
Ventilation
Process of loading O2 onto hemoglobin
Oxygenation
Exchange of oxygen & CO2 in the alveoli & tissues
Respiration
Gas exchange at the cellular level
Internal respiration
Respiration is dependent on:
Adequate oxygenation
Brain damage is irreversible after _ _ _ minutes without adequate oxygenation
10
Clinical state characterized by increased RR and work of breathing
Respiratory distress
Normal resting minute ventilation volume of an average person
6 L/min
Resting alveolar minute volume is approximately:
4 L/min
Pulmonary artery blood flow is approximately:
5 L/min
Average v/q ratio is:
4:5 L/min, or 0.8 L/min
When ventilation is compromised but perfusion continues unhindered, the result is:
V/q mismatch
Most Common airway obstruction in an unresponsive patient:
The tongue
Purposefully shallow breathing to alleviate pain from a chest or thorax injury
Respiratory splinting
Hypoventilation is typically directly linked to
PaCO2 levels in the blood
_ __ occurs when Carbon dioxide elimination exceeds carbon dioxide production
Hyperventilation
Buildup of Carbon dioxide in the blood
Hypercapnia
Condition caused by blood bypassing the alveoli and returning to the left side of the heart unoxygenated
Intrapulmonary shunting
Pulmonary edema is related to __
Left sided heart failure
Peripheral edema is a result of __
Right sided heart failure
