Doctors usually consider anything between 70 and 100 mmHg to be normal. A MAP in this range indicates that there’s enough consistent pressure in your arteries to deliver blood throughout your body.
You can do without the pulmonary valve and live. In fact you can do without a tricuspid valve and live; there was a surgeon that used to do tricuspid valvectomies for endocarditis. You don't live well; you'll eventually have to have the tricuspid valve replaced.Jun 20, 2017
Systemic vascular resistance (SVR) reflects changes in the arterioles2, which can affect emptying of the left ventricle. For example, if the blood vessels tighten or constrict, SVR increases, resulting in diminished ventricular compliance, reduced stroke volume and ultimately a drop in cardiac output.May 25, 2017
The normal pulmonary artery systolic pressure is 20 mm Hg or less, and the normal mean (average) pulmonary artery pressure is 12 mm Hg. A number of disease processes affect the pulmonary circulation and increase the pressure levels in the pulmonary arteries and right ventricle.
SVRI is calculated as 80*(MAP-CVP)/CI, where CI is cardiac index ; and the formula equals 80*(MAP-CVP)/(CO/BSA), where BSA is body surface area. This formula may also be presented as SVRI=SVR*BSA, and the normal values of SVRI range from 1900 to 2400 dynes s m2/cm5 , , .
Cannon A waves, or cannon atrial waves, are waves seen occasionally in the jugular vein of humans with certain cardiac arrhythmias. When the atria and ventricles contract simultaneously, the blood will be pushed against the AV valve, and a very large pressure wave runs up the vein.
The normal range (95% CI) of peak exercise RVSP is 12.2 mmHg to 57.4 mmHg in men, and 11.2 mmHg to 58.0 mmHg in women. The normal range for patients younger than 50 years, 50 to 75 years, and older than 75 years of age was 11.7 mmHg to 52.5 mmHg, 11.4 mmHg to 58.6 mmHg, and 15.3 mmHg to 64.5 mmHg, respectively.
The pulmonary wedge pressure (PWP), also called pulmonary arterial wedge pressure (PAWP), pulmonary capillary wedge pressure (PCWP), pulmonary artery occlusion pressure (PAOP), or cross-sectional pressure, is the pressure measured by wedging a pulmonary catheter with an inflated balloon into a small pulmonary arterial
Typically, this means that the venous waves are visible just above the clavicle when the patient is sitting at 30-45 degrees. With the JVP, the vessel is the internal jugular vein, and the fluid is the venous blood it contains. Look carefully on both sides of the neck for the JVP.
