[Change in nCPAP pressure in repeated follow-up of patients with obstructive sleep apnea].

Ambulatory screening devices are gaining increasing acceptance for control measurements after CPAP therapy. This method has several disadvantages, however. For example, it cannot be determined, using ambulatory devices, whether a decrease in air pressure is possible. In addition, if a continuation of breathing problems exists, a full polygrafic recording is required. In repeated control studies it was determined if, and to what extent, air pressure could be altered. Results indicate that in up to 50% of the cases changes in pressure were needed. It is concluded, at least in at-risk patients or those with compliance problems, a polygrafic recording is necessary.
