The Pulse Oximeter BSM 382 is a portable
measuring device for easy, uncomplicated and
precise measurements of arterial oxygen
saturation as well as pulse rate and pulse intensity
(display as bar and wave chart) at any time. The
device features an adjustable acoustic and visual
alarm function.
Using the Pulse Oximeter BSM 382, the oxygen
saturation level of the arterial haemoglobin
(SpO2) can be easily measured on a finger. The
measurement is carried out by two light sources
with different wavelengths being shone through
the finger and hitting a photo electrode on the
other side. The photo electrode determines which
portions of the light have passed through the
finger. Depending on the blood oxygen saturation,
different portions of the light pass through the
finger. Based on these measurements, the device
determines the saturation level, making blood
samples unnecessary.
