The Essential Role of Power Supply Units in Respiratory Devices
#

Continuous Positive Airway Pressure (CPAP) devices and oxygen concentrators are foundational technologies in respiratory care, supporting patients with conditions such as Obstructive Sleep Apnea (OSA) and Chronic Obstructive Pulmonary Disease (COPD). These devices are designed to maintain stable breathing and optimal blood oxygen levels, and their effectiveness is closely tied to the reliability of their power supply units.

A dependable power supply is crucial for uninterrupted operation. CPAP machines require a steady flow of pressurized air to keep airways open, while oxygen concentrators rely on consistent power to operate compressors and oxygen separation systems, delivering high-purity oxygen. Any instability—such as voltage fluctuations or power interruptions—can compromise therapy and patient safety.

Efficiency, Safety, and Compliance
#

Medical-grade power supplies must meet rigorous international standards. High efficiency, such as compliance with Level VI energy efficiency, reduces both operational and standby power consumption—an important benefit for home-based users. Adherence to IEC 60601 standards ensures low leakage current, minimizing electrical risks and enhancing patient safety.

Modern power supply units incorporate advanced protection features, including safeguards against overvoltage, overcurrent, short circuits, and overheating. These mechanisms maintain stable operation under varying conditions, protecting both the device and the patient. In the event of power anomalies or equipment overload, the unit intervenes promptly to prevent system damage or therapy disruption.
