You may be at risk for in-flight hypoxia
When flying at high altitudes, hypoxia can impair your ability to read, reason, think, see and even talk. These cognitive functions are necessary to fly you and your passengers safely. Depending on your age, overall health condition, etc. - hypoxia can occur as low as 5,000 feet.
To prevent the onset of hypoxia, AeroMedix recommends the use of a fingertip pulse oximeter to give you a measurement of the amount of oxygen in your arterial blood. Coupled with a supplemental oxygen system, a pulse oximeter can help you avoid hypoxia before it begins to impair your judgment.
AeroMedix offers a full line of fingertip pulse oximeters ranging from inexpensive entry level models to prescription, clinical grade units. Feel free to contact us if you have any questions regarding these products and their use.
