looks at the ability of air to reach all parts of the lungs, while the perfusion part evaluates how well blood circulates within the lungs. As Q in physiology...

studied in animal and human for decades. Before the implementation, the perfusion system will be selected and the process can be similar to organ bath...

precede this clinical instruction. Early in their clinical training, the perfusion student may have little involvement outside of an observational role...

completed, the signal is processed to generate an image that shows the perfusion on a screen. The laser Doppler effect was first used to measure microcirculation...

changes in light absorption. A conventional pulse oximeter monitors the perfusion of blood to the dermis and subcutaneous tissue of the skin. With each...

extracts the fluid through the other tube. While outside the tubes, the perfusion fluid picks up physiological substances such as neurotransmitters that...

laparoscopic approach is used to stir the abdominal content during the perfusion. Lotti M called into question the statement that the Coliseum technique...

single session. Angiography provides important information regarding the perfusion and patency of distal arteries (e.g. femoral artery). The presence of...

patient through a mouthpiece or mask that covers the nose and mouth. The perfusion phase of the test involves the intravenous injection of radioactive...

is standard, but 1.5 T is satisfactory). In order to properly scale the perfusion values into cerebral blood flow units (CBF, ml/100g/1 min), a separate...

such as seen during use of diuretics. Instead, experiments isolating the perfusion pressures seen by glomerular capillaries from heightened systemic pressures...

the contrast reaches the renal cortex and renal medulla) to evaluate the perfusion and vascularity of the kidneys. CT scan taken at 90 to 180 seconds (when...

Ventilation-perfusion mismatch is the term used when the ventilation and the perfusion of a gas exchanging unit are not matched. The actual values in the lung...

perfusion information. A second phase "blood pool" image following the perfusion (if carried out in a three phase technique) can help to diagnose inflammatory...

amplitude and time course (similar to the b value). In both cases, the perfusion effect results in a curvature of the diffusion attenuation plot towards...

perfusion defect (ischaemia). The position in the left ventricle of the perfusion defects are described using the AHA 17 segment model. Stress CMR cannot...

medicine tests, directly assess the function of the kidney by measuring the perfusion and excretion of radioactive substances through the kidneys.[citation...

renin–angiotensin system, increases fluid retention in the body, increases the perfusion of glomerulus, thus increasing glomerular filtration rate (GFR). At...

diastolic blood pressure Mean arterial pressure is a major determinant of the perfusion pressure seen by organs in the body. MAP levels greater than 90 mmHg...

centers, reduces the risk of ischemic spinal cord injury by increasing the perfusion pressure to the spinal cord. A 2012 Cochrane systematic review noted...
