When you are first diagnosed with sleep apnea, a physician will usually provide you with a prescription for CPAP treatment. You then take this prescription to a homecare provider, who will help you start your treatment.
This homecare provider is particularly important at the start of your treatment. They should help you learn more about sleep apnea, the treatment process, and set you up with therapy treatment. Most providers will allow you to try the CPAP machine for a month, during which time they should help you adopt therapy into your daily life and ensure that the treatment is having the intended result.
In the longer-term, your homecare provider should help you maintain your CPAP equipment, supply you with replacement parts, solve any equipment problems, and help monitor your therapy progress for when your sleep apnea treatment needs change.
