Yes, you do.  If you are a patient we have already registered your device but, both the provider and the patient need to register for the recall.
You can register your machine on the Philips website or by phone (1-877-907-7508) to ensure that Philips knows your machine is active.
Please see the Addendum to the Position Statement from the Canadian Thoracic Society, Canadian Sleep Society and the Canadian Society of Respiratory Therapists here for more details.
