Pulse Oximeter
Posted by admin on April 14th, 2008
This Pulse Oximeter uses ADuC7024 MicroConverter.Pulse oximetry (PO) is considered to be the “fifth vital sign” of health status.It is a medical device that measures the amount of oxygen in a patient’s arterial blood.A typical oximetry sensor has a pair of light-emitting diodes (LEDs) facing a photodiode through a translucent part of the patient’s body, usually a fingertip or an earlobe. One LED is red, with wavelength of 660 nm; the other is infrared, with a wavelength of 940 nm. The percentage of blood oxygen is calculated based on the absorption rate from each wavelength of light after it passes through the patient’s body. [via]
