To reduce time committment and expense in the diagnosis of sleep apnea it is necessary to develop simplified monitoring techniques. The monitoring systems to detect apneas should have high sensitivity, good reproducibility, be inexpensive and practical to use. The following methods have been suggested: inductance plethysmography, capnography, flow measurements by thermistors, tracheal sound recording, static charge sensitivity bed, oximetry, activity monitoring, detection of snoring. Some devices to registrate breathing have been combined with oximetry and other methods. The results have been validated by polysomnography and show rather good correlations. However, there exists no information on the time and cost savings of a step wise diagnosis of sleep apnea.
