1. How long does ResMed S9 last?

The ResMed S9 CPAP motor is designed to last approximately 24,000 hours, equivalent to over eight years of continuous use at 8 hours per night. However, the motor may produce louder sounds over time, indicating needing replacement. 

Changing the filters can help extend the lifespan of the motor. If the motor needs repair or replacement, it can be done to ensure the continued functionality of the ResMed S9 CPAP machine.

2. Can you wear CPAP all day?

Wearing a CPAP machine during the day is possible but generally not recommended for routine use. CPAP is designed for nighttime use to treat sleep-related breathing disorders like sleep apnea. Using it during waking hours is usually unnecessary unless medically advised for specific conditions like severe respiratory issues or COPD. For most individuals, CPAP use during sleep at night is sufficient to manage sleep apnea and ensure better breathing during restful sleep. Consult a healthcare professional for personalized guidance.

3. Why replace CPAP after five years?

CPAP machines typically have a lifespan of around five years. After this time, various components of the machine and accessories may begin to wear out, affecting the effectiveness of the therapy. The mask’s headgear, cushion, and pillows can stretch out, the tubing can develop tears or cracks, and air filters can wear out, leading to air leaks or reduced airflow. 

Regularly replacing CPAP equipment is essential to ensure optimal performance and maintain the effectiveness of sleep apnea therapy. This practice helps to ensure that the machine functions properly and provides effective treatment for the user.

4. How many hours is a CPAP machine suitable for?

A CPAP machine is ideally used for the entire duration of sleep during the night, aiming for seven or more hours. CPAP compliance measures the number of hours and nights a patient uses the therapy and how consistently it is used for effective treatment. 

Consistently using CPAP for the recommended duration ensures optimal benefits in managing sleep-related breathing disorders, such as obstructive sleep apnea, and helps improve overall sleep quality and health outcomes.
