The SleepCube BiLevel S is a variation on traditional CPAP. Instead of providing air at a constant pressure all night, the machine “senses” if you are breathing in or out and varies its level of pressure accordingly.
On inspiration a higher pressure is needed to prevent apneas, hypopneas or snoring. On expiration a lower pressure is adopted to ensure patient comfort with less resistance.
A BiLevel S is particularly beneficial for those users who require a higher pressure setting.
