NXP® offers ultra-low-power MCUs that support LCD displays for portable pulse oximeters, which track oxygen levels in a patient’s blood.
These devices offer a simple, non-invasive method to monitor the percentage of hemoglobin in the blood that is saturated with oxygen. Saturation level and heart rate are displayed on an LCD display.
Pulse oximeters come as standalone, portable units or as part of a larger patient monitoring system.
Speed development time when designing your portable medical device with Our Healthcare Analog Front End (AFE) reference platform which includes a complete hardware platform, schematics and software. Based on the Kinetis Microcontroller K53 measurement.
