Oxygen Transport Dissolved in plasma:
(vol % = 0.0031 (ml O2 /100cm3/mmHg)
x PaO2
Bond to Hemoglobin: 1.34 ml of O2/g of Hb x g of Hb x g of
Hb/100 cm3 x % Saturated
Cyanosis
Approximately 5 g/dl of unoxygenated hemoglobin in the capillaries (> 5 gHb / 100ml of blood)
Heart Sounds S1: “ lub” occurs at the beginning of
systole (mitral and tricuspid close) S2: “dub” marks the start of diastole,
(aortic and pulmonic close) S3: (ventricular gallop) early signs of CHF
S4: (atrial gallop) pulmonic stenosis, aortic stenosis, hypertension, MI &
cardiomyopathy
