The headgear has four adjustable straps that converge into a single back panel. It also has a crown strap to provide extra support while sleeping.
The replacement headgear is available in the same size that comes with the Wisp (Standard) and also in a Large Size.
Warning: Magnetic clips with a field strength of less than 400 mT are used in the mask.* With the exception of the devices identified in the contraindication, ensure that the mask is kept at least 6 inches (approx. 15 cm) away from any other medical implants or medical devices that can be impacted by the magnetic fields to avoid possible effects from localized magnetic fields. This includes household members, caregivers, and bed partners that may be in close vicinity to patients that use the masks.
*The application of Philips Respironics’ magnetic headgear clips and straps - according to the previous, as well as the current updated instructions and labeling - complies with the guidelines from the International Commission of Non-Ionizing Radiation Protection (ICNIRP), as well as the ISO 14117:2019-09 standard, for use of magnetic elements in proximity of implanted medical devices.
