Lab Values Flashcards
1
Q
SpO2
A
98-100%
-88-90% requires supplemental O2
2
Q
PaO2
A
90-100 mmHg
3
Q
PaCO2
A
35-45 mmHg
- increase = COPD, hypoventilation
- decrease = hyperventilation, pregnancy, PE, anxiety
4
Q
pH
A
7.35-7.45
5
Q
How to read ABG
A
- look at pH
- Then CO2, if <35 then alkalosis, if >45 acidosis
6
Q
High pH, high CO2
A
metabolic alkalosis
7
Q
High pH, low CO2
A
respiratory alkalosis
8
Q
Low pH, high CO2
A
respiratory acidosis
9
Q
Low pH, Low CO2
A
metabolic alkalosis
10
Q
Prothrombin time
A
11-15 seconds
-increase in factor X deficiency, hemorrhagic disease, cirrhosis
11
Q
INR
A
- 9-1.1
- pts on anticoagulants 2-3
- pts w/ clotting disorder 3.5
12
Q
White Blood Cell
A
- 4300-10,800 (5000-10,000)
- increase = infection
- decrease = aplastic anemia
13
Q
Hematocrit (% of RBC of whole blood)
A
- male 45-52%
- female 37-48%
- increase = erthrocytosis, dehydration, shock
- decrease = poor exercise tolerance, fatigue, tachycardia
14
Q
Hemoglobin
A
Male- 13-18
Female 12-16
-increase polycythemia, dehydration, shock
-decrease= anemias, poor exercise tolerance, fatigue, tachycardia
15
Q
Platelet count
A
150,000-450,000 cells increase = chronic leukemia decrease = thrombocytopenia, acute leukemia <20,000= AROM, ADLs only 20k-30k = light exercise only 30k-50k = moderate exercise
