Auto-CPAP gives an opportunity to decrease costs of evaluating patient with OSA, replacing manual titration of pressure during PSG. The aim of this study was to compare automatic (auto-CPAP) and manual CPAP pressure titration in patients with OSA. We studied 50 obese patients (BMI--35 +/- 6 kg/m2), mean age 52.4 +/- 9.4 years with severe OSA, mean: AHI--62.9 +/- 22.1, mean overnight SaO2--89.1 +/- 3.7%, T90--54.4 +/- 29.6%. Two polysomnographies were performed: first when patient slept with CPAP and pressure was titrated manually by a technician and second on auto-CPAP device. Both methods had similar efficacy in reduction of AHI (< 10/h) and hypoxaemia, despite lower pressure established during auto-CPAP mode preventing apnoeas and hypopnoes during 90% of sleep time (8.2 +/- 1.7 cm H2O) compared to manual CPAP titration (9.2 +/- 1.7 cm H2O) (p < 0.05). CONCLUSION: Auto-CPAP seems to be a reliable alternative to manual titration of the therapeutic pressure in patients with OSA. This may help to cut a waiting list for PSG of patients suspected of OSA.
