Outward forces of pulm capillaries:
pulmonary capillaries: Interstisial osmotic interstial: |
pulm cap: 7 mmHg
interstitial osmotic : 14 mmHg interstial hydrostat : -8 mmHg Total: 29 mmHg |
|
|
inward forces of plasma osmotic pressure
|
28 mmHg

|
Reasons for pulmonary edema
|
1. Increased resistance to flow through pulmonary vessels increase hydrostatic P.
2. Increased vascular permeability means higher Kf, greater protein leakage and therefore greater fluid leakage. |
|
|
Types of pulmonary edema
|
1. Interstitial
2. Alveolar |
|
