Background: This paper aims to fill a research gap in the existing literature by investigating the impact of control, transient, and steady-state responses on the effectiveness of continuous positive airway pressure (CPAP) devices in the treatment of obstructive sleep apnea syndrome (OSAS).
Method: Bench tests were conducted on five CPAP devices: DreamStar Duo ST (SEFAM), Point 2 (Hoffrichter), Respironics PR System One Pro (Philips), iBreeze 20A (ResVent), and Respaps (MedTech). The evaluation focused on the transient responses of these devices to a pre-adjusted breathing pressure of 10 cmH2O. Parameters such as delay time, rise time, peak time, settling time, overshoot percentage, and steady-state error were measured and analyzed.
Results: The study revealed significant variations in the transient responses among the tested CPAP devices, attributed to the unique manufacturer algorithms. The observed differences underscore the importance of understanding and considering device-specific characteristics when selecting a CPAP device.
Conclusions: This research emphasizes the critical role of choosing the appropriate CPAP device for optimal patient outcomes, particularly for individuals experiencing breathing difficulties associated with OSAS. The findings highlight the need for careful consideration of device characteristics to ensure the effective treatment of sleep apnea using CPAP machines.
