RCIS Board Exam Study notes based on Glowacki and Sommers MP3 Exam Questions And Answers What is the pressure as blood enters the right atrium? 5mmHg What organ system in the body acts on the blood in the vessels to make a pressure of 5mmHg? Deep skeletal muscle pump system What pressure is the blood under as it goes from the RA through the tricuspid valve? 5mmHg The bigger the diameter of the valve the __________ pressure is needed to move blood across it. Less The smaller the diameter of the valve the _________ pressure is needed to move blood across it. more What is the largest valve in the heart? tricuspid valve What is the normal right ventricular systolic pressure? 25mmHg How much smaller is the pulmonic valve than the tricuspid valve? 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? Tricuspid Which valve requires more pressure to move across it, the tricuspid or the pulmonic? pulmonic Valve A requires 5mmHg to move blood and valve B requires 30mmHg. Which valve has a smaller diameter? Valve B What is the right ventricular diastolic pressure? 5mmHg What is the RV EDP? 5mmHg Why is the RV EDP not zero? Because some blood is not ejected out. The heart is not a perfectly efficient pump. What is a normal RV ejection fraction? 55-60% What is EDP? 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. What is a normal diastolic pressure in the pulmonary artery? 7-12mmHg What is the normal left atrial pressure? 7-12mmHg What is the normal O2 concentration of a RBC leaving the lungs? 98% What is the normal O2 concentration of a RBC when it returns to the RA? 70% How much O2 is a RBC able to give up to the organs? 30% of it What is the pressure as blood enters the right atrium? 5mmHg What organ system in the body acts on the blood in the vessels to make a pressure of 5mmHg?
