cerebral oxygen saturation are weighted venous samples (70% venous, 30% arterial) Pulse oximeter values are based on arterial oxygen saturations.
what's the noramal pulse for the adulte
The perfusion index (PI) is a numerical value that reflects the pulse strength at a specific site, typically measured by a pulse oximeter. It ranges from 0.02 to 20, with higher values indicating better peripheral perfusion. A normal PI is generally considered to be between 0.4 and 4.0, although this can vary based on the individual and the measurement conditions.
There are a number of them: the Pulse Oximeter- requiresa pulse so is placed on an artery. It uses red and infrared light to measure the colour of the blood. If blood is oxygenated it is bright red and absorbs/reflects light differently to darker blood which is deoxygenated. Benarons monitor is similar to pulse oximeter but uses shorter light (blue and green). This is used to monitor capillaries and does not require a pulse hence is suitable when perforning things like bypass surgey.
at least 15 to 20 seconds
Well pulse pressure is systolic (top) minus diastolic (bottom). So the value you get should be between 30-49 to be normal.

In pulse amplitude modulation (PAM), you send a single pulse of a certain height (amplitude) that represents the value of the sampled signal at that time. With pulse code modulation (PCM), you take the same sampled value, but now represent that value by N bits, where N is the number of quantized regions. Why send a whole bunch of bits instead of just a single pulse? Because PCM performs better in situations of higher noise (AWGN).
SGOT normal value is 15-37.

The main feature of a pulse monitor is, of course, measuring the pulse of the person wearing it. Another feature is to then display this value as both a number and a graph on another machine.
Both pulse and impulse are the types of unit step function. In case of impulse the response gains the value for short duration of time and then becomes 0 while in case of pulse it is not neccessary that the value of response become 0 after an interval it may remain constant also.............
