Comparison of Auto- and Fixed-Continuous Positive Airway Pressure on Air Leak in Patients with Obstructive Sleep Apnea: Data from a Randomized Controlled Trial

Figure 1

Classification of patients according to leakage reported by machines; median leak value was determined for each brand. (a) Distribution of leak magnitudes in the ResMed devices expressed as unintentional leakage (L/min) (x-axis). (b) Distribution of leak magnitudes in the Philips devices expressed as unintentional leakage (L/min) (x-axis). (c) Distribution of leak magnitudes in the WEINMANN devices expressed as unintentional leakage (L/min) (x-axis).
