CPAP (Continuous Positive Airway Pressure) machines utilize water in a humidifier chamber to add moisture to the pressurized air delivered to the user. The amount of water consumed depends on several factors, including the humidifier’s settings (higher settings use more water), the ambient humidity, the duration of use, and the machine’s design. A typical user might observe anywhere from a few milliliters to the full capacity of the water chamber being depleted overnight.
Humidification is a crucial component of CPAP therapy for many users. Dry air can lead to nasal congestion, dryness, irritation, nosebleeds, and sore throats, potentially decreasing compliance with therapy. Adding moisture improves comfort and reduces these side effects, promoting consistent use and the effectiveness of CPAP treatment in managing sleep apnea. Historically, CPAP machines did not incorporate humidifiers, and users frequently experienced these issues. The integration of heated humidification represents a significant advancement in CPAP technology, enhancing patient experience and treatment outcomes.
