Cardiac Physiology…Part 1 Pages 18-22 Left heart pressures > Right heart pressures MV & TV are atrioventricular valves ○ Open during diastole AoV & PV are semilunar valves Before we jump in, ○ Open during systole p. 18 let’s remember… Remember how blood transfers from areas of higher pressure to low pressure? ○ The difference of pressure between two locations is called a pressure gradient PGs are responsible for opening & closing the valves…it all depends where the pressure is highest! This concept applies throughout the entire p. 20 cardiac cycle! p. 18 Normal Cardiac Pressures (mmHg) RAP: 2-8 (mean pressure) RVP: 15-25 2-8 (diastolic pressure transfer!) PAP: 15-25 (systolic pressure transfer!) 4-12 PCWP: 2-12 (transfer from PA, split in half to each lung!) LAP: 2-12 (transfer from PCWP / lungs!) LVP:
