A heated moisture unit provides supplemental humidity to the pressurized air delivered by continuous positive airway pressure (CPAP) therapy devices. This heated humidity can alleviate common CPAP side effects, such as dryness of the nasal passages, throat, and mouth. One example is a passover humidifier, which directs air over a heated water reservoir. Another example is a chamber humidifier, which bubbles air through heated water before delivery to the patient.
Adding moisture to the airflow improves patient comfort and compliance with CPAP therapy, a crucial treatment for obstructive sleep apnea. Dry air can irritate sensitive mucous membranes, leading to nosebleeds, congestion, and sore throats. Humidification addresses these issues, promoting restful sleep and the overall effectiveness of the therapy. The development of these devices has significantly improved the tolerability and therefore the efficacy of CPAP treatment since its widespread adoption.
