Finger Pulse Oximeter - (blood oxygen saturation meter)
A device that measures blood oxygen saturation (%SpO2) and pulse rate

Our Finger Pulse Oximeters are high quality, Health Canada licenced finger pulse oximeters suitable for both medical use and use by athletes, pilots or anyone travelling, working or training at high altitudes.

Hypoxia is a pathological condition in which the body as a whole (generalized hypoxia) or a region of the body (tissue hypoxia) is deprived of adequate oxygen supply. Generalized hypoxia occurs in healthy people when they ascend to high altitude, where it causes altitude sickness leading to potentially fatal complications: high altitude pulmonary edema and high altitude cerebral edema. Hypoxia also occurs in healthy individuals when breathing mixtures of gases with a low oxygen content, e.g. while diving underwater especially when using closed-circuit rebreather systems that control the amount of oxygen in the supplied air. A mild and non-damaging intermittent hypoxia is used intentionally by athletes during altitude trainings to develop an athletic performance adaptation at both the systemic and cellular level. A Finger Pulse Oximeter is invaluable for monitoring blood oxygen saturation for these situations.

Because of their simplicity and speed, pulse oximeters are of critical importance in emergency medicine and are also very useful for patients with respiratory or cardiac problems, especially COPD, or for diagnosis of some sleep disorders such as apnea and hypopnea.


Some Terminology used with Pulse Oximetry:

Perfusion Index or PI is the ratio of the pulsatile blood flow to the non-pulsatile static blood flow in a patient's peripheral tissue, such as finger tip, toe, or ear lobe. Perfusion index is an indication of the pulse strength at the sensor site. The PI's values range from 0.02% for very very weak pulse to 20% for extremely strong pulse. The perfusion index varies depending on patients, physiological conditions, and monitoring sites. Because of this variability, each patient should establish his own "normal" perfusion index for a given location and use this for monitoring purposes.

Perfusion index is normally monitored with pulse oximeters. PI is also a good indicator of the reliability of the pulse oximeter reading. For most pulse oximeters for general use, the reading is unreliable or unavailable if PI is at or below 0.4%.

The pleth (Plethysmograph), available in many pulse oximeters, is a graphical representation of the perfusion index.
