A 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...

متن کاملAWearable Pulse Oximeter
Group Members: Fanpeng Kong, Yubo Qin, Zhengyu Yang and Zhongtian Lin Advisor: Prof. Laleh Najafizadeh Introduction The aim of this project is to design a wearable pulse oximeter which is capable of measuring the heart-rate and blood’s oxygen saturation. The project employs wearable electronics. The project consists of three main parts: 1) sensor design, which includes the optical transceiver u...
متن کاملA Three-Wavelength Pulse Oximeter for Carboxyhemoglobin Determination
Pulse oximetry measures the relative concentration of arterial oxygenated hemoglobin and reduced hemoglobin. This paper presents the design of a pulse oximeter, which measures the presence of a third substance, carboxyhemoglobin (HbCO), by unfiltered LEDs at 660 nm, 810 nm, and 940 nm. Background information is given on the theory of pulse oximetry. Theoretical approximations and calculations w...
متن کاملComparative 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...
