A comparison of pulse oximeters during helicopter flight.
Pulse oximetry would be an invaluable parameter to monitor during patient transport. While original models of oximeters were not battery powered nor very portable, this has changed. Seven currently available commercial pulse oximeter models were evaluated in the noisy vibration-prone environment of a helicopter. Three (3) units were judged to be unacceptable on the basis of weight, duration of battery life, or lack of ease of use. In two (2) units, the sampling algorithms appeared to interface with their performance. Of the seven (7) units tested, two (2) units were found to be reliable, portable, and easy to use. The use of portable pulse oximetry monitors should rapidly become routine during the transport of critically ill patients.
