near drowning
thermal injury
inhalation of toxic gases
trauma
sepsis
shock
high altitude illness
pulmonary embolism
ARDS
pulmonary lymphatic obstruction
aspiration of gastric contents
disseminated intravascular coagulation

CARDIOGENIC PULMONARY EDEMA
DEFINITION:
Interstitial edema, including fluid engorgement of the perivascular and peribronchial spaces and the alveolar wall interstitium.
ETIOLOGY:
Arrhythmias , MI , severe systemic hypertension
Pulmonary embolism , valvular heart disease
Increased pulmonary capillary wedge pressure
PATHOPHYSIOLOGY:
Cardiogenic pulmonary edema occurs when the pulmonary capillary pressure exceeds the forces that maintain fluid within the vascular space (serum oncotic pressure and interstitial hydrostatic pressure).
Increased pulmonary …
