Labeled pulse oximeter diagram. 1 2 their package inserts indicate the. Peripheral pulse oximeters are one of the most widely used medical monitoring technologies. 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. Although the food and drug administration fda considers all pulse oximeters to be prescription medical devices most sold in drugstores or on the internet are specifically labeled not for medical use and were not reviewed by fda for accuracy.

Now the only light that falls on the detector is the room light. This reference design features afe4403 ti s high performance analog front end for pulse oximeters an ultra low power microcontroller and a highly optimized. The scope of this document is to provide a miniaturized pulse oximeter reference design for high end clinical application. A block diagram of the circuit for a pulse oximeter is shown in figure 37.

Finally the pulse oximeter switches off both the red and infrared led lights. This is an i2c supported sensor and communicates with the arduino board through i2c communication bus. The main sections of this block diagram are now described. 4 1 7 testing for pulse rate accuracy for oximeters labeled with low perfusion performance claims we recommend testing in accordance with clause 201 12 1 103 of iso 80601 2 61 2011.

The pulse oximeter is implemented using the freescale medical oriented microcontroller kinetis k53. Because the pulse oximeter now knows the level of room light it is able to subtract it from the readings to get the actual red and infrared light levels. Peripheral pulse oximeters are one of the most widely used medical monitoring technologies. This mcu embeds a 32 bit arm cortex m4 processor ethernet usb connectivity and an analog measurement engine ideal for medical applications.
