What is pulse oximetry?

Pulse oximetry is a useful method of monitoring patients in many circumstances, and in the face of limited resources, the pulse oximeter may represent a wise choice of monitor, as with training it allows for the assessment of several different patient parameters.

What is SpO2?

SpO2 means, that the oxygen saturation levels are being measured repeatedly, every few milliseconds.
Each measure gives a Spot-like image of current oxygen saturation level.

Who can use it?

Patients who need to monitor SpO2 level
Pilots exposed to hypoxia at high altitudes
Asthma patients
COPD patients
Mountain climbers and others engaged in high altitude activity

How does Meditech oximeters operate?

The oximeter works according to Lambert Beer Law: Our oximeters omits a near-infrared pulse (a 660nm ray and 940nm near-infrared ray). The light passes through the skin, "hits" red blood cells, and is partially absorbed. The part which isn't absorbed is picked up by the photoelectric sensor, and being analyzed. The analysis is calculated according to the haemoglobin (R Hb) and Oxyhemoglobin (02 Hb) reflectance factor. Reflectance factor, is an index that shows the exact amount and length of light that a substance will absorb, when it is being "hit" by a certain  wavelength of light.
