| Question | Answer |
|---|---|
| Normal Hypoxemia | 80-100mmHg |
| Mild Hypoxemia | 60-79mmHg |
| Moderate Hypoxemia | 40-59mmHg |
| Severe Hypoxemia | < 40mmHg |
| Age correction for Hypoxemia: every year over age 60 subtract 1 mmHg from | 80mmHg |
| PaO2 < 40mmHg = | severe hypoxemia |
| Pa02 < 60-65mmHg = | indicates hypoxemia |
| CaO2 / Oxygen content | (Hb x 1.34 x SaO2) + (PaO2 x .003) |
| CaO2 normal | 17-20mL O2/dl |
| PAO2 | [(PB-47) x FiO2] - PCO2 x 1.25 |
| PAO2 normal @ rest on RA | 5 - 15mmHg |
| PAO2 @ exercise on RA | 15 - 30mmHg |
| PAO2 on 100% O2 | 25 - 65mmHg |
| V/Q mismatch | 66 - 300mmHg |
| Shunt | >300mmHg |
| P/F ratio | PaO2/FiO2 |
| P/F normal | 380 - 480 |
| P/F acute lung injury | <300 |
| P/F acute respiratory distress | <200 |
| Oxygen Index (O/I) | PIP x FiO2 / PaO2 |
| Oxygen Index normal | <10 |
| Adult arterial pH | 7.40 (7.35-7.45) |
| Adult arterial PCO2 | 40 (35-45) |
| Adult arterial PO2 | 97 (80-100) |
| Adult arterial HCO3 | 24 (22-26) |
| Adult arterial BE | 0 (+/- 2) |
| Adult arterial Hb | 14 (12-16) |
| Adult arterial CaO2 | 20 ( 17-20) |
| Adult arterial COHb | <2% |
| Adult arterial MetHb | <1% |
| Adult venous pH | 7.35 |
| Adult venous PCO2 | 46 |
| Adult venous HCO3 | 40 |
| Adult arterial BE | 0 |
| Adult venous Hb | 14 |
| Adult venous SvO2 | 70-75% |
| Adult venous CvO2 | 15 |
| Neonate pH | 7.33 |
| Neonate PCO2 | 47 |
| Neonate PO2 | 60 |
| Neonate HCO3 | 25 |
| Neonate BE | - 4 |
| If temperature increases | pH decreases |
