Parameter Vital Capacity FEV₁ FVC Arterial Po2 Venous Po2 COPD O Pulmonary fibrosis Pulmonary oedema Value 3160 ml 2420 ml 3020 ml 100 mmHg 53 mmHg O Methemoglobinaemia (causes a leftward shift in the oxygen-haemoglobin dissociation curve)
A child weighing 22 lbs, has an infection and the doctor orders erythromycin drops 2.0 mLp.o. q6h. The bottle states that the usual dosage is 20.0-40.0 mg/kg/day, and there are35.0 mg per 1.5 mL. Find the min and max dosage per day in mL. Is the order within therecommended dosage?
DA-LTE Blood is flowing through a bundle of hollow fiber tubes that are each 50 µm in diameter. There are 10,000 tubes in the bundle. The hollow fiber tube length is 12 cm and the pressure drop across each tube is found to be 250 mmHg. The hematocrit of the blood is 0.40. Estimate the blood flow rate for these conditions in each tube.

Do you think erythropoietin levels in athletes at low altitude are lower, higher, or the same after training at a high altitude for 2 months? Explain your answer. Calculate the average ml of oxygen molecules in 100 ml blood in the athletes at low altitude and then in athletes in high altitude while training at high altitude. Use the following information: 1.39 ml of oxygen per gram of hemoglobin. Do athletes training at high altitudes have more or less oxygen molecules per ml of blood then athletes training at low altitudes? Explain why this difference gives athletes who train at high altitudes an advantage over athletes who train only at low altitudes.
