Physiology Flashcards
1
Q
Hypoxia
A
low levels of O2 in the tissues
2
Q
Hypoxemia
A
low PO2 levels in the the arterial blood
3
Q
SaO2
A
percent O2 bound to Hb in arterial blood
4
Q
PaO2
A
partial pressure (mmHg) of O2 dissolved in blood
5
Q
hypoxic pulmonary vasocontriction
A
blood vessels near the a collapsed alveoli will constrict and direct the blood flow to the normal alveoli
6
Q
Hyperventilation
A
Increased RR
May cause Hypocarbia
7
Q
Hypocarbia
A
decreased PCO2 in the blood
8
Q
Hypoventilation
A
decreased RR
may lead to hypercarbia
9
Q
Hypercarbia
A
increased PCO2 in blood
10
Q
Lung Compliance/Cl
A
ease of dispensability or elasticity of the lungs
11
Q
Elastance
A
- The desire of something to return to its normal shape
- Increased Cl will have lower elastance
- decreased Cl ill have higher elastance
12
Q
Airway Resistance
A
Raw; is the resistance of the movement of air through an airway
13
Q
Increased Raw
A
difficulty in passing of air or ventilation to alveoli for gas exchage–> collapse–> shunt
