Transcutaneous monitoring of oxygen tension during progressive hypoxia and sleep. 1988

Department of Lung Medicine, Uppsala University, Sweden.

Transcutaneous O2 monitoring (PtcO2) was studied in 16 adult subjects suspected of having sleep-related breathing disorders, by comparison with arterial O2 measurements (PaO2). At rest the mean difference (+/- SD) between PaO2 and PtcO2 was 3.6 (+/- 1.5) kPa. During progressive hypoxia 74 simultaneous measurements showed a mean decrease in PtcO2 from the beginning to the end of the hypoxic tests of 6.6 (+/- 1.4) kPa for PtcO2 and 7.1 (+/- 1.5) kPa for PaO2. The decrease in PtcO2 was slower than that in PaO2 during the first minute (p less than 0.001), but for the whole hypoxic period there was no difference in the rate of decrease between the two methods. Continuous PtcO2 monitoring has been found useful in detecting respiratory abnormalities during sleep.

D010100	Oxygen	An element with atomic symbol O, atomic number 8, and atomic weight [15.99903; 15.99977]. It is the most abundant element on earth and essential for respiration.	Dioxygen,Oxygen-16,Oxygen 16
D001785	Blood Gas Monitoring, Transcutaneous	The noninvasive measurement or determination of the partial pressure (tension) of oxygen and/or carbon dioxide locally in the capillaries of a tissue by the application to the skin of a special set of electrodes. These electrodes contain photoelectric sensors capable of picking up the specific wavelengths of radiation emitted by oxygenated versus reduced hemoglobin.

D012891	Sleep Apnea Syndromes	Disorders characterized by multiple cessations of respirations during sleep that induce partial arousals and interfere with the maintenance of sleep. Sleep apnea syndromes are divided into central (see SLEEP APNEA, CENTRAL), obstructive (see SLEEP APNEA, OBSTRUCTIVE), and mixed central-obstructive types.
