Understanding CPAP Machines and How They Work

Continuous Positive Airway Pressure (CPAP) machine is a therapy option for patients with sleep apnea. Sleep apnea is a sleep disorder that causes breathing to stop and start repeatedly during the night. A CPAP machine can reduce the frequency of pauses in breathing by delivering a constant stream of air pressure through a mask.

  • The CPAP machine comprises a pump that generates the pressured air, a tube that carries the airflow, and a mask that fits over the nose and/or mouth to deliver the air pressure to the airway.
  • The air pressure from the machine creates a pneumatic splint around the airway to prevent it from collapsing or narrowing during sleep, allowing patients to breathe steadily during the night.
  • CPAP machines can be set to deliver various air pressure levels, based on the patient’s prescribed treatment pressure, which can be determined during a sleep study.

CPAP machines are typically powered by electricity, with the power consumption varying depending on some factors. The wattage of a CPAP machine can be affected by different factors such as:

  • The type and model of CPAP machine
  • The ramp-up time and pressure of the machine
  • The humidifier used, if included
  • The type of mask worn by the patient

Although some CPAP machines have a low power consumption of around 25 watts, some can use as much as 90 watts or more. The table below shows some popular CPAP machines and their power consumption:
