Annual deaths from tornadoes, earthquakes and floods together total fewer than 200. The most deadly heat wave in recent years occurred in Chicago over a week in July 1995, when temperatures hovered around 100 degrees.
Cardiac Cycle: 1st Systole Phase. During the systole phase, the right ventricle receives impulses from the Purkinje fibers and contracts. The atrioventricular valves close and the semilunar valves open. The de-oxygenated blood is pumped into the pulmonary artery.
Hold the Doppler probe absolutely still. It can easily slip offthe artery. 5. Measure the systolic blood pressure: a. Inflate cuffquickly to maximal inflation level (30 mmHg above systolic pressure). b. Deflate at 2 mmHg/second, to appearance of systolic pressure. c. Follow down for 10 mmHg.
