Comparative Analysis of Pulse Oximeter
Pulse oximetry is a non-invasive method for monitoring a person's O2 saturation. In its most common (transmissive) application mode, a sensor device is placed on a thin part of the patient's body, usually a fingertip orearlobe, or in the case of an infant, across a foot. The device passes two wavelengths of light through the body part to a photodetector. It measures the changing absorbance at e...
متن کاملWavelet analysis of pulse oximeter waveform permits identification of unwell children.
BACKGROUND Children who are unwell often display signs of circulatory compromise. It has been observed that pronounced changes occur in the appearance of the photoplethysmogram (pulse oximeter tracing) in these children. The aim of the study was to discover if wavelet transforms can identify more subtle changes in the photoplethysmogram of children who are unwell. METHODS Photoplethysmograms ...
متن کاملA Pulse Oximeter
The objective of this work was to develop a prototype for a pulse oximeter. Given the necessity, in most medical interventions, to monitorize Oxygen saturation in peripheral blood (SpO2) a pulse oximeter is highly necessary in any operating room or intensive care unit. The electronic device was built recurring mostly to Integrated Circuit (IC) and its control was performed via a programmed micr...
