Measurement of the field metabolic rate is made using the doubly labeled water method, although alternative techniques, such as monitoring heart rates, can also be used. The advantages and disadvantages of the alternative approaches have been reviewed by Butler et al. [1] Several summary reviews have been published. [2] [3] [4]

It was replaced in 1978 by the Dinamap 845 which could also measure systolic and diastolic blood pressure, as well as heart rate. [19] The oscillometric method uses a sphygmomanometer cuff, like the auscultatory method, but with an electronic pressure sensor to observe cuff pressure oscillations, electronics to automatically interpret them, and ...
A bioassay is an analytical method to determine the potency or effect of a substance by its effect on living animals or plants (in vivo), or on living cells or tissues (in vitro). [1] [2] A bioassay can be either quantal or quantitative, direct or indirect. [3] If the measured response is binary, the assay is quantal; if not, it is quantitative ...
Modalities applied to measurement of ejection fraction is an emerging field of medical mathematics and subsequent computational applications. The first common measurement method is echocardiography, [7] [8] although cardiac magnetic resonance imaging (MRI), [8] [9] cardiac computed tomography, [8] [9] ventriculography and nuclear medicine (gated SPECT and radionuclide angiography) [8] [10 ...
The heart is at the top of the back, just behind the head, and the average heart rate is about 180 bpm under normal conditions. Daphnia spp., like many animals, are prone to alcohol intoxication, and make excellent subjects for studying the effects of the depressant on the nervous system due to the translucent exoskeleton and the visibly ...
Floyer wanted to develop a watch to measure the accurate pulse rates of his patients. Floyer created a watch that counted a user's heart beat for sixty seconds, it created an easier way to count and measure the heart rate of patients. Floyers' designs were physically made by Samuel Watson, who was involved in horology in the late seventeenth ...
The HR is often used to compute the heart rate variability (HRV) a measure of the variability of the time interval between heartbeats. HRV is often used in the clinical field [6] to diagnose and monitor pathological conditions and their treatment, but also in the affective computing research to study new methods to assess the emotional state of ...
