Abstract
Pulse oximetry is a noninvasive method for monitoring a person’s oxygen saturation. It is an electronic device and
instrument that measures the electrical impulse of the of human heart and the number of beats per minute at which
the heart pumps blood into the body. An average man, school or hospital should be able to easily afford a pulse
oximeter for personal, teaching and emergency purposes, respectively. This is not the case due to the cost of this
device and this is the reason this project was embarked upon. This work builds a low power, low cost, reliable and
non-invasive monitoring device that accurately measures the level of SPO2 and pulse rate in the blood of a patient
or an individual. LM358 was used in this project and the electrodes in the transmitter senses the heart electrical
impulse and sends the information to a receiver in the form of a watch, to obtain and record results which were
found to be accurate and within normal range and standards. The results and readings are as obtained from some
patients in the medical ward of University of Ilorin Teaching Hospital. This type of proximity device is essential for
a patient suffering from hypertension, asthma and other various heart diseases. In spite of the successful design
and construction of the device, battery failure (life cycle), deterioration of the components, among others, are some
of the challenges associated with the device. Recommendations on how to improve the system have been given.
