A person demonstrates how to assess capillary refill time (CRT) on a dummy [1] Capillary refill test on index finger pulp. [2]Capillary refill time (CRT) is defined as the time taken for color to return to an external capillary bed after pressure is applied to cause blanching. [3]
In medicine, the mean systemic pressure (MSP) or mean systemic filling pressure (MSFP) is defined as the mean pressure that exists in the circulatory system when there is no blood motion. A similar term, mean circulatory filling pressure , (MCFP) is defined as the mean pressure that exists in the combined circulatory system & pulmonary system ...
Anatomical terminology is a specialized system of terms used by anatomists, zoologists, and health professionals, such as doctors, surgeons, and pharmacists, to describe the structures and functions of the body. This terminology incorporates a range of unique terms, prefixes, and suffixes derived primarily from Ancient Greek and Latin.
The modified Allen's test is also performed prior to heart bypass surgery. The radial artery is occasionally used as a conduit for bypass surgery, and its patency lasts longer in comparison to the saphenous veins. Prior to heart bypass surgery, the test is performed to assess the suitability of the radial artery to be used as a conduit.
In cardiac physiology, preload is the amount of sarcomere stretch experienced by cardiac muscle cells, called cardiomyocytes, at the end of ventricular filling during diastole. [1] Preload is directly related to ventricular filling. As the relaxed ventricle fills during diastole, the walls are stretched and the length of sarcomeres increases.
The human body consists of many interacting systems of organs. These interact to maintain homeostasis, keeping the body in a stable state with safe levels of substances such as sugar and oxygen in the blood. [58] Each system contributes to homeostasis, of itself, other systems, and the entire body. Some combined systems are referred to by joint ...
The circulatory system uses the channel of blood vessels to deliver blood to all parts of the body. This is a result of the left and right sides of the heart working together to allow blood to flow continuously to the lungs and other parts of the body. Oxygen-poor blood enters the right side of the heart through two large veins.
