Finger pulse oximeter was
developed in 1972 by Takuo Aoyagi, is a non-invasive medical device for
monitoring a patient’s oxygen saturation and producing a photoplethysmogram. In
its application, a sensor is placed on a thin part of the patient’s body
usually a fingertip and in the case of an infant, across a foot. Two waves of
light are passed through the patient’s to a photo detector. The changing
absorbance in each of the wavelength is measured.
Reflectance pulse Oximetry may be
used as an alternative to transmissive pulse Oximetry. This method does not
require a thin section of the patient’s body and is therefore well suited to
more universal application such as the feet, forehead and chest. The pulse
oximeter may be incorporated into a multiparameter patient monitor. Mostly
monitors display the pulse rate and most are Portable, battery-operated pulse oximeters
are available for transport or home blood oxygen monitoring.
Because of their simplicity of
use and the ability to provide continuous and immediate oxygen saturation
values, finger pulse oximeter are of critical importance in emergency medicine and
also very useful in any setting including intensive care, operating, recovery
and determining the effectiveness of or need for supplement oxygen.
