DARAY′s V409 is a simple and accurate fingertip pulse oximeter

The device simultaneously measures the oxygen saturation in the blood (%SpO2) and the patient′s pulse rate (BPM); it also displays an indication of pulse strength. The V409 is self contained, light and powered from 2 AAA alkaline batteries which should last for at least 30 hours continuous operation. Auto shutdown after 8 seconds prolongs battery life, and an indicator shows battery state.

How it works:
The V409 pulse oximeter projects an LED-produced light of specific wavelength through the fingernail. A sensor on the other side of the finger passes the received light to a microprocessor which interprets the changes in the received light and converts it to a recognisable format which is shown on the Clear, wide angle OLED display.
