ARDS (noncardiogenic pulmonary edema): Difference between revisions

Line 19:

**Pulmonary edema -- Respiratory failure NOT fully explained by cardiac failure or fluid overload. This vague statement further says "as judged by the treating physician using all available data" and that if there are no ARDS risk factors (i.e. causes) present, that objective assessment such as Echo is need to exclude CHF.

**Oxygenation -- a PaO2/FIO2 ratio <300 on PEEP or CPAP of '''at least 5 cmH2O'''.

***e.g: PaO2=55 on 50% O2 ---- P/F ratio = 55/0.5 = 110

*Note:

**ARDS is actually a histopathologic delineation of a specific pattern of lung parenchymal injury. This pattern is called Diffuse Alveolar Damage (DAD) and can only be truly diagnosed with a tissue sample assessed under the microscope, which is rarely done in such patients.
