Many Puritan Bennett devices in the GoodKnight series include the ability to read patient data regarding sleep therapy. Thus, physicians will have access to downloadable data and will be able to custom tailor even better therapy to the specific needs of each patient.

  • Most machines use proprietary SilverLining 3.6 software

  • Physicians can have access to downloading information from each night of sleep therapy

  • The doctor & the patient can track much better the apnea/hypopnea index

The CPAP devices in the GoodKnight range represent the best choice for patients who travel often. The devices are lightweight, and they are FAA approved so the patient can take the device on board. These CPAP devices provide more freedom of movement to the patients.

Patients noncompliant with regular CPAP therapy, will find extremely efficient the Bi-Level machine in the GoodKnight series. The GoodKnight 425 Bi-Level device is actually one of the smallest, quietest and most portable Bi-Level machines available out there. The machine is lightweight with only 1.5 lbs. so it represents the perfect solution for active patients who travel frequently and need CPAP therapy on the go. This machine is an extremely popular choice among patients who cannot use Continuous Airway pressure therapy because they find it difficult to produce an exhale against a high pressure CPAP coming from the machine.

The bi-level device can be set with one pressure for exhale and another pressure for inhalation. Therefore CPAP therapy becomes more comfortable and breathing becomes more natural.

Please contact SleepRestfully for any question regarding the GoodKnight series of CPAP or Bi-level machines or accessories by Puritan Bennett. Here, you will find only top quality devices offered by world leading brands, and the most competitive prices.
