CA720 Continuous Positive Airway Pressure Ventilator (Single-Level)

Product Introduction

The CA720 Continuous Positive Airway Pressure (CPAP) Ventilator is a single-level positive airway pressure device designed for sleep breathing therapy. Supporting both CPAP and APAP treatment modes, it provides continuous or automatically adjusted positive airway pressure to support breathing during sleep.

Developed with a focus on noise reduction and user comfort, the CA720 integrates an independently developed high-performance fan, intelligent respiratory sensing technology, and advanced motor control algorithms. Its i-Sense intelligent sensing algorithm detects subtle changes in breathing and dynamically adjusts treatment pressure according to respiratory conditions.

The device also features a preheating humidification system, adjustable heated tubing, SD card data storage, cloud-based data management, and Bluetooth connectivity with compatible pulse oximeters. These functions provide a comprehensive solution for sleep respiratory therapy and treatment data management.

Performance Features

•  CPAP and APAP Modes: Supports continuous positive airway pressure and automatic positive airway pressure therapy.

• Low-Noise Operation: Optimized fan and airflow duct design help reduce operating noise, with a specified noise level of ≤29 dB.

•  Intelligent Respiratory Sensing: The i-Sense algorithm detects respiratory changes in real time and dynamically adjusts treatment pressure.

•  High-Performance Fan: Independently developed fan technology is designed to provide smoother airflow and a more comfortable breathing experience.

•  Heated Humidification: Integrated preheating and humidification help deliver warm, humidified airflow throughout treatment.

•   Delay Pressure Boost: Adjustable delay boost function from 5 to 45 minutes.

•  Adaptive Leak Compensation: Automatically adjusts the baseline in response to air leakage, helping maintain treatment synchronization and respiratory event recognition.

• Respiratory Event Recognition: Identifies apnea-hypopnea events, airflow limitation, central sleep apnea, Cheyne-Stokes respiration, and Biot's breathing.

• Bluetooth Oximeter Connectivity: Can connect wirelessly to a compatible pulse oximeter and display SpO₂ data.

•   Long-Term Data Management: Stores approximately two years of usage data on an SD card and supports connection to Hepule Smart Health Cloud for long-term data storage.

Working Principle

The CA720 delivers positive airway pressure through a breathing circuit and compatible nasal mask or nasal pillow interface. In CPAP mode, the device supplies continuous pressure to help maintain airway patency during sleep. In APAP mode, its intelligent sensing system monitors respiratory patterns and adjusts pressure within the configured treatment range.

The i-Sense algorithm processes signals from high-precision sensors to identify respiratory events and changes in airflow. When breathing conditions change, the system dynamically adjusts pressure to provide responsive therapy.

The integrated humidification system heats and humidifies the delivered airflow to improve breathing comfort. Adaptive leak compensation helps account for mask or circuit leakage, supporting pressure delivery and respiratory event detection.

Treatment data can be recorded on an SD card and transferred to the Hepule Smart Health Cloud when connected. Bluetooth connectivity also enables compatible pulse oximeter data, including SpO₂, to be displayed.
