Respiratory 3 Flashcards
1
Q
Minute Ventilation
A
total amount into or out of respiratory tract in one minute
2
Q
Forced Vital Capacity
A
lung function + recoil
how much can be blown out after a deep breath
3
Q
Forced Expiratory Volume
A
how much air can be blown out in a certain period of time
4
Q
Emphysema
A
High Compliance
Low Recoil
easy to breathe in, hard to breathe out
5
Q
Non-respiratory Air Movements
A
cough sneeze crying laughing hiccups yawns
6
Q
Composition of Alveolar Gas
A
- more CO2 + water vapor than air BECAUSE gas exchange in lungs humdification of air mixing of gases with each breath
7
Q
ventilation-perfusion coupling
A
gas and blood flow reaching alveoli COUPLED for better gas exchange
8
Q
Life span of RBC
A
120 days
9
Q
rate of loading and unloading O2
regulated by:
A
pressure of O2 temp blood pH pressure of CO2 concentration of DPG
10
Q
Hypoxia
A
not enough O2 to tissues
- too little RBCs
- blocked circulation
- carbon monoxide (has more affinity for Hb)
11
Q
CO2 transported in 3 forms
A
- plasma
- bound to Hb
- as bicarbonate
