The science behind SleepWeaver Élan® PAP Mask
The SleepWeaver® achieves a good seal and quiet operation using the properties of a balloon. When a balloon is inflated, all points inside the balloon are at the same pressure. This air pressure pushes the wall of the balloon until the tension in the wall of the balloon or something outside the balloon pushes back.
The SleepWeaver® takes advantage of this property. The pressure inside of the mask is the same at all points. So the pressure being applied to the patient for their CPAP therapy is the same pressure that pushes the mask against the patient’s skin. This creates a good seal between the cloth of the mask and the skin of the patient.
There are several advantages of this method over conventional CPAP masks. The cloth in the mask conforms to the features of the patient’s face, so the mask forms a very good seal. There is no additional pressure required to hold the mask onto the patient’s face, so there is no need for excess tension in the straps. The pressure exerted by the mask is the same at all points, so there are no localized pressure points that can create pressure sores.
