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...

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...

We monitored 12 patients undergoing major abdominal surgery using a pulse oximeter (Nellcor N-200) and a transcutaneous oxygen tension monitor (TINA, Radiometer A/S) on the second or third night after operation. Of the shortest hypoxaemic episodes measured with the pulse oximeter (< or = 30 s duration), 78% also occurred in the transcutaneous oxygen tension measurement. Episodes of longer durat...

A pulse oximeter is a medical device that indirectly monitors or measure the oxygen saturation of a patient's blood (as opposed to measuring oxygen saturation directly through a blood sample) and changes in blood volume in the skin, producing a photoplethysmogram. The pulse oximeter may be included into a multi parameter patient monitor. This also displays the pulse rate. There are many portabl...

Pulse oximetry is a ubiquitous non-invasive medical sensing method for measuring pulse rate and arterial blood oxygenation. Conventional pulse oximeters use expensive optoelectronic components that restrict sensing locations to finger tips or ear lobes due to their rigid form and area-scaling complexity. In this work, we report a pulse oximeter sensor based on organic materials, which are compa...
