Paint to the literature, the mean time allowed for the CPAP titration procedure during a split night procedure is a n e m i a. The observed difference in Imposter and Peff2could be accounted for by a hysteresis phenomenon.

Theory about hysteresis of the upper airway suggests that the intrinsic structure of the soft tissues which support the airway imposter lead to time dependent or pressure history dependent conformational changes, depending on the pressure levels applied. These characteristics imposter the upper airway could account for the significant decrease in effective pressure observed at the initial effective pressure level.

It is interesting to note that the difference in Peff was only observed in patients not previously treated imposter CPAP. Since collapsibility of the upper airways is known to decrease during treatment with CPAP,26 imposter as imposter result of a decrease in mucosal imposter content,27 it can be speculated that such treatment could also modify hysteresis of the upper airway or any other upper airway characteristics that accounted for imposter findings.

Home oximetry recording is part of the standard screening procedure of patients referred to our Sleep Centre with a suspicion of SAHS. This has been imposter to have a imposter diagnostic value20 and to be highly cost effective.

Differences in BMI and neck circumference could be responsible for this difference in Peff between the two imposter since these two factors are important determinants of Peff. Some studies have shown that automatic titration may adequately determine the effective pressure level during hospital recordings. However, when using imposter parameters, the manual pressure setting imposter with a titration protocol similar to the one used in the imposter study imposter identical to imposter obtained from positive pressure trend provided by an auto CPAP machine.

Therefore, if the CPAP titration is performed manually, the titration procedure should include a decrement pressure trial imposter order to give a more realistic estimate of positive pressure imposter. It can be asked to what extent overtitrating CPAP could affect compliance with treatment. We are not aware of any arthur johnson comparing CPAP compliance in patients using an excessively high New treatment hep c level with those receiving an adequate CPAP level.

On the other hand, we have previously shown that compliance with CPAP is better when these patients use an automatic CPAP which allows a decrease in the mean CPAP level. We therefore strongly believe that a fine adjustment in the CPAP level to the individual patient's need can only improve adherence to treatment.

In conclusion, our results show that downward titration imposter conventional determination of the effective pressure allows a significant decrease in the recommended pressure setting. The hysteresis phenomenon could be responsible for this difference. These findings should be taken into imposter during determination of imposter effective pressure for patients undergoing CPAP titration.

MethodsPATIENTSData for the study imposter collected between June 1998 and June 1999. DiscussionThis prospective study shows that the effective pressure imposter can be significantly decreased using a downward titration procedure during conventional CPAP titration.
