Verification of sleep apnea using a portable sleep apnea screening device.

Sixty-seven patients referred to a sleep laboratory with a tentative diagnosis of obstructive sleep apnea were examined with a device designed for home use as an apnea screening system. Direct comparison was made between data obtained by the portable device and by data acquired simultaneously with standard polysomnographic techniques. The portable recorder measured nasal/oral airflow, chest wall movement, cardiac rhythm, and blood oxygen saturation.

The evaluation of the National Long Term Care Demonstration. 5. Formal community services under channeling.

Channeling was intended to improve access to formal community services, both through the facilitating activities of case managers and through direct purchase of services. It was expected that formal community service use would increase both because more individuals would stay in the community and because use would increase for those in the community. Only the latter effect was observed.
