Heart sound. What we hear ? We have all heard the heart make the usual sounds. LUB DUB Lub is the first sound or S1 Dub is the second heart sound.

Pulse Sound Activity. Heartbeat Each heartbeat is called a cardiac cycle: two atria contract then two ventricles contract (systole), and the entire heart.

Arterial Blood Gas (ABG) Normal Ranges  pH  PaCO mmHg  PaO mmHg

Oxyhemoglobin Dissociation Curve

Oxygen Transport Dissolved in plasma:  (vol % = (ml O 2 /100cm 3 /mmHg) x PaO 2 Bond to Hemoglobin:  1.34 ml of O 2 /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)

Cardiac Assessment Ref: Bates 8 ed

Heart Sounds S 1 : “ lub” occurs at the beginning of systole (mitral and tricuspid close) S 2 : “dub” marks the start of diastole, (aortic and pulmonic close) S 3 : (ventricular gallop) early signs of CHF S 4 : (atrial gallop) pulmonic stenosis, aortic stenosis, hypertension, MI & cardiomyopathy

Professional Conduct Introduce yourself Explain the procedure / examination to the patient Ask the patient if they have any questions Cover the patient with a sheet. Only expose area examining while performing a procedure/examination
