A male patient has presented with the following results for spirometry and plasma Po2. What is your diagnosis? (Use your lecture notes to derive the normal range for these parameters. Also note that usually plasma O₂ is determined by saturation percentage, not Po2, but humour me here). Parameter Vital Capacity FEV₁ FVC Arterial Poz Venous Po2 Value 3560 ml 2110 ml 3120 ml 90 mmHg 35 mmHg O COPD O Pulmonary fibrosis O Pulmonary oedema O Methemoglobinaemia (causes a leftward shift in the oxygen-haemoglobin dissociation curve)

The following patient all has severe edema for different reasons. Your challenge is to explain the cause of the edema. In each case, try to explain the edema in terms of either an increase or a decrease in one of the four pressures that cause bulk flow at capillaries. A picture may be useful. Patient : Mr. Herrera  Mr. Herrera is arriving in an ambulance in anaphylactic shock due to a bee sting. During anaphylactic shock, the capillaries become leaky, and plasma proteins that normally stay inside the blood vessels “escape” into the interstitial fluid. Which pressure is altered in this case, and how is it causing edema?
