Technical Specifications Comparison

The document appears to compare technical specifications of three different devices or models, focusing on operational ranges, modes, and features.

Operational Ranges and Modes

• Angle or range: -60 to +60 degrees for two devices; unspecified for the third.
• Intensity levels: Low, Medium, High for one device; Low and High for the others.
• Time settings: 0 to 5.0 seconds across all devices.
• Display types: Bar or Graph for one device; Bar only for others.
• Operating modes: Auto, Manual, Percussor, and No setting for two devices; Auto and Manual for one device.

Presets and Percussor Mode

• Presets: 9 presets for one device; 3 presets for another; not applicable for the third.
• Percussor mode frequency ranges: 10 to 780 cpm (cycles per minute) for one device; 10 to 600 cpm for another; not applicable for the third.
• Pressure ranges: 0 to 70 cmH2O and 0 to 60 cmH2O for two devices; not applicable for the third.

Additional Features

• Amplitude and frequency: Amplitude 1 to 10 cmH2O and frequency 1 to 20 Hz specified for one device only.
• Cough synchronization (flow trigger), SpO2, and heart rate data are not available in any device.
• Foot switch, SD card, and comfort reader features are absent in all devices.
• Battery: One device has a detachable battery; others do not.

Power Supply and Safety
