CPAP machines, essential for treating sleep apnea, require electrical power to function. The power consumption of these devices, typically measured in watts, varies depending on the specific model, pressure settings, and features like heated humidification. A typical CPAP machine might use between 30 and 60 watts. A machine operating at higher pressure settings will generally consume more power. Additional features, such as a heated humidifier or heated tubing, will also increase the overall power usage.
Understanding a CPAP machine’s power requirements is crucial for several reasons. It allows users to estimate operating costs and helps determine the suitability of the device for different power sources, including battery backups during travel or power outages. Accurate power consumption information also facilitates comparisons between different CPAP machine models, aiding consumers in making informed purchasing decisions. Historically, CPAP machines were larger and less energy-efficient. Advances in technology have led to smaller, more portable, and energy-efficient models.
