Auto CPAP device for monitoring and treating sleep apnea in adults. Ideal for healthcare centers as well as home treatment, it is particularly easy to use and transport, with a modern design, comfortable LCD screen, and easy menu. The unit operates either continuously (CPAP) or automatically (AUTO-CPAP) and prevents sleep apnea by adjusting the pressure according to the patient's needs. It may include a heated humidifier function that can be activated and deactivated by the operator. It has a reminder function for changing the filter or mask, checking the device, or retrieving data from the memory card. The device's ramp function provides a gradual increase in pressure so that the patient can sleep easily. In automatic mode, the ramp function allows for the slowing down of pressure increase or decrease commands. When the device is in continuous CPAP mode, the nurse can modify the preset pressure by +/-1cm H2O (Pressure Alter function). With the Comfort Calibration+ function, the Auto CPAP device increases the pressure during inhalation and decreases the pressure during exhalation, thus helping the patient breathe more comfortably. It has an external memory card either for retrieving the most recent monitoring data from the device's memory or for updating the device's parameters. It includes a carrying case, flexible tube, reusable filter, power cord, memory card, and user manual for the patient.
