Arterial Blood Gas Values Flashcards
1
Q
PaO2
A
80- 100
values for older adults may be lower
2
Q
Elevations in PaO2
A
may indicate excessive oxygen administration
3
Q
Decreased PaO2 levels
A
indicative of:
- asthma
- anemia
- resp distress syndrome
- cancer of the lungs
- other causes of hypoxia
4
Q
PaCo2
A
35-45
5
Q
Elevated PaCO2
A
indicate:
- pneumonia
- asthma
- COPD
- anesthesia effect
- use of opioids (respect acidosis)
6
Q
Decreased PaCO2 levels
A
indicate:
- hyperventilation
- resp alkalosis
7
Q
HCO3
A
21-28
8
Q
Elevated HCO3
A
may indicate:
- resp acidosis as compensation for primary metabolic alkalosis
9
Q
Decreased levels of HCO3
A
may indicate:
- resp alkalosis as compensation for primary metabolic acidosis
10
Q
SpO2 saturation
A
95-100%
11
Q
Decreased levels of O2 saturation
A
May indicate impaired ability of hemoglobin to release oxygen to tissues
