chapter 9 Flashcards
Ventilation
movement of air into and out of lungs
During exhalation intrathoracic pressure exceeds what
atmospheric pressure
hypoxia
inadequate delivery of oxygen to the cells
oxygenation
delivery of oxygen to the blood
Respiration
exchange of carbon dioxide and oxygen
Brain Damage
- happens in 4 mins
- perminent in 6 mins
- irricoverable in 10 mins
Stridor
high pitched noise indicating partial upper airway obstruction
SPO2
measure the percentage of the hemoglobin that is saturated with oxygen
OPA
measure from the corner of the mouth to the tip of the earlobe
NPA
measure from the tip of nose to the earlobe, DO NOT USE IF FACE INJURY
