The two types of pulmonary edema

Fluid can sometimes build up in the lungs, and we generally refer to this as pulmonary edema.  There are two types of pulmonary edema: 

1.  Caradiogenic:  Fluid backs up from a weakened heart.  Pulmonary pressure increases, and this fluid is forced into the parychemal tissue lining the bronchi and alveoi.

2.  Noncardiogenic:  The heart did not cause the pulmonary edema.  There is a simple pneumonic to remember all the disorders that fit into this category:  NOT CARDIAC.  As noted:
  • Near drowning
  • Oxygen therapy
  • Transfusion or Trauma
  • CNS disorder
  • ARDS, aspiration or altitude sickness
  • Renal disorder or resuscitation
  • Drugs
  • Inhaled toxins
  • Allergic alveolitis
  • Contrast or contusion
