Finger Pulse Oximeter Diagram
However if the probe is of the wrong size or has not being applied properly some of the light instead of going through the artery goes by the side of the artery shunting lower finger in image below.
Finger pulse oximeter diagram. The pulse oximeter is implemented using the freescale medical oriented microcontroller kinetis k53. This device is especially important for people who need to monitor these parameters due to certain health conditions such as asthma or congestive heart failure. Pulse oximeters are less accurate if there is poor blood flow to the finger. The fingertip pulse oximeter is designed to be used in specified electromag netic environment.
Users of the fingertip pulse oximeter must use it in the. Carbon monoxide due to smoke inhalation carbon monoxide poisoning or heavy cigarette smoking results in falsely high pulse oximeter readings. This document is intended to be used by biomedical. Pulse oximeter using freescale products.
The pulse oximeter is a small clip like device that attaches to a body part like toes or an earlobe. The pulse oximeter operates best when all the light passes through arterial blood as shown in the upper finger in the image below. Maintenance with data such as circuit diagram components list figure and the detailed rules of correction injection available only to the repair. This mcu embeds a 32 bit arm cortex m4 processor ethernet usb connectivity and an analog measurement engine ideal for medical applications.
