Blood salvage
A collection of the siphoned blood that has escaped from the operative site of non-contaminated surgeries so that after appropriate filtration it may be returned to the patient.
-
Ambulatory blood pressure monitoring
The measurement with a portable blood pressure monitor of blood pressure of outpatients. It is used to record the patient’s diastolic and systolic pressures during activity and rest throughout the day.
-
Normal blood pressure
A blood pressure between 100 and 120 mm Hg systolic and< 80 mm Hg diastolic.
-
Negative blood pressure
Blood pressure that is less than atmospheric pressure, as in the great veins near the heart.
-
Mean blood pressure
The sum of twice the diastolic blood pressure plus the systolic blood pressure, all divided by 3.
-
Indirect measurement of blood pressure
A simple external method for measuring blood pressure.
-
Direct measurement of blood pressure
Determination of the blood pressure within the lumen of an artery or within a chamber of the heart with a catheter introduced into the organ and attached to a pressure-monitoring transducer. It is done by placing a sterile needle or small catheter inside an artery and having the blood pressure transmitted through that system to…
-
Chronic low blood pressure
A condition in which the systolic blood pressure is consistently less than 100 mm Hg. In the absence of associated disease, low blood pressure is often a predictor of longevity and continued health.
-
Central blood pressure
Blood pressure in the heart chambers, in a great vein, or close to the heart. If determined in a vein, it is termed central venous pressure; if in the aorta or a similar large artery close to the heart, it is designated central arterial pressure.
-
Augmented diastolic blood pressure
An increase in diastolic pressure, usually by an artificial device, such as an intra-aortic balloon pump.
