- Mild pulmonary venous hypertension (15–20 mmHg) produces isolated dilatation of the upper zone vessels.
- Interstitial oedema occurs when the pressure is between 21 and 30 mmHg - fluid collections in the interlobar fissures, interlobular septa (Kerley B lines)
- Alveolar oedema occurs when the pressure exceeds 30 mmHg

- present in 15% to 25% of patients ultimately diagnosed with pulmonary emboli

Correct! Wrong!

Normal potassium levels are between 3.5 and 5.0 mmol/L (3.5 and 5.0 mEq/L) with levels below 3.5 mmol/L defined as hypokalemia
