Design and Development of Pulse Oximeter
نویسندگان
چکیده
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 portable oximeters are available in the market, but they are not so accurate. To make accurate oximeter we are using here ARM based microprocessor/ microcontroller. In this paper our main emphasis is on accuracy and displaying Haemoglobin Level.

A 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 کاملNovel Wearable and Wireless Ring-Type Pulse Oximeter with Multi-Detectors
The pulse oximeter is a popular instrument to monitor the arterial oxygen saturation (SPO2). Although a fingertip-type pulse oximeter is the mainstream one on the market at present, it is still inconvenient for long-term monitoring, in particular, with respect to motion. Therefore, the development of a wearable pulse oximeter, such as a finger base-type pulse oximeter, can effectively solve the...

Background & Aim: Pulse Oximeter monitoring technology has become so common in intensive health care settings over the last decade that blood oxygen level is now considered as the fifth vital sign. However, it seems that medical and nursing staffs are not specially educated to operate with the devices. The aim of the study was to investigate the knowledge of medical assistants (residents), nurs...
