RCIS Board Exam Study notes based on Glowacki and Sommers MP3 with Complete Solution What is the pressure as blood enters the right atrium? -Answer 5mmHg What organ system in the body acts on the blood in the vessels to make a pressure of 5mmHg? -Answer Deep skeletal muscle pump system What pressure is the blood under as it goes from the RA through the tricuspid valve? -Answer 5mmHg The bigger the diameter of the valve the __________ pressure is needed to move blood across it. -Answer Less The smaller the diameter of the valve the _________ pressure is needed to move blood across it. -Answer more What is the largest valve in the heart? -Answer tricuspid valve What is the normal right ventricular systolic pressure? -Answer 25mmHg How much smaller is the pulmonic valve than the tricuspid valve? -Answer 5x smaller. It takes 5mmHg to get across the tricuspid valve and 25mmHg to get across the pulmonic valve. Which valve has a bigger diameter, the tricuspid or pulmonic valve? -Answer Tricuspid Which valve requires more pressure to move across it, the tricuspid or the pulmonic? -Answer pulmonic Valve A requires 5mmHg to move blood and valve B requires 30mmHg. Which valve has a smaller diameter? -Answer Valve B What is the right ventricular diastolic pressure? -Answer 5mmHg What is the RV EDP? -Answer 5mmHg Why is the RV EDP not zero? -Answer Because some blood is not ejected out. The heart is not a perfectly efficient pump. What is a normal RV ejection fraction? -Answer 55-60% What is EDP? -Answer End Diastolic Pressure. An efficient heart has an ejection fraction of 55-60%, this leftover blood in the ventricle is under a resting (diastolic) pressure
