NUR355 MED SURGE: EXAM 3
1. what is ventilation
*Answer√√ the "in and out" of air movement
2. what is respiration
*Answer√√ gas exchange of O2 and CO2 in the alveoli
3. what is perfusion
*Answer√√ carrying O2 to the rest of the body
4. what is surfactant
*Answer√√ phospholipid and protein substance that covers the alveoli to prevent it from collapsing
5. what is compliance
*Answer√√ the ease of the lung expansion
6. what is hypoxia
*Answer√√ insuflcient O2 to meet the needs of tissue cells in the organs
7. what lab values determine hypoxemia
*Answer√√ PaO2 <60 (ABGs) SaO2 <90 (Pulse Ox)
,8. T/F :you can have hypoxia of an organ with regular numbers (hypoxia with-
out hypoxemia)
*Answer√√ true
** cells of a tissue are unable to utilize oxygen despite having normal blood and tissue levels...
** the blood delivery is normal, but the tissues themselves are not able to utilize the oxygen in the blood
9. example of a ventilation problem
*Answer√√ pneumothorax
a collapsed
10. example of respiratory problems
*Answer√√ - COPD
- asthma
11. example of perfusion problems
, *Answer√√ blood clots
12. examples for an increased need for oxygen
*Answer√√ - fever
- infection
- anxiety
- anemia
13. what respiratory problem would be CONTRAINDICATED for high levels of
oxygen
*Answer√√ COPD
** dont give large amounts of O2 or else you will knock out their O2 drive
** COPD patients rely on low oxygen levels to stimulate their breathing.. so if they receive too much oxygen, they will
breathe less, causing a build up of CO2
14. normal pH levels
, *Answer√√ 7.35-7.45
15. normal PaO2 (partial pressure of oxygen in arterial blood)
*Answer√√ 80-95mmhg
