|
Definition
Inadequate gas exchange at alveoli
Hypoxemia--even with 100% 02
Decreased pulmonary compliance
Dyspnea
Bilateral pulmonary edema
White out appearance on X-ray (dense pulmonary infiltrates)
There is no abnormal lung sounds!!!
Low PO2 (PO2 < 50 mm Hg) |

Definition
| Positive End Expiratory Pressure--small amounts of air instilled into the alveolar sacs at the end of exhalation to prevent these alveoli from collapsing. |
