Calibration of the Average Breathing Rate Measurement of the Cloud DX Pulsewave Health Monitor (PAD-2A) Device (CCV-3)

Calibration of the Average Breathing Rate Measurement of the Cloud DX Pulsewave Health Monitor (PAD-2A) Device (CCV-3)

The purpose of this study is to calibrate the average breathing rate measurement of the PAD-2A device to be within ±2 breaths per minute of clinical capnography breathing rate measurements.

The plan for this study is to calibrate the average breathing rate measurement of the PAD-2A device with the breathing rate measurement of a standard clinical capnography device. The data will be collected and analyzed in order to calibrate the PAD-2A device via the capnography measures by adjusting the device algorithm for the breathing rate measurements to be within ±2 breaths per minute. Additionally, the secondary objective of this study is to compare the clinical standard respiratory rate measurement of capnography with the respiratory rate measurements of other standard clinical respiratory devices (i.e. nasal pressure transducer, thermistor, and the respiratory inductance plethysmography (RIP) belts of the chest and abdomen).

Inclusion Criteria:

• Adults ≥ 19 years of age (minimum 30% male/female)

• Wrist circumference between 13.5cm - 23cm (5.3 in. - 9.1in.)

  • Specifically for this test device, the wrist size of the consented participants will be distributed accordingly for a Gaussian distribution:

Lowest Octile: ≥ 13.5cm to < 14.7cm Lower Quarter: ≥ 13.5cm to < 15.9cm Lower-Middle Quarter: ≥ 15.9cm to < 18.3cm Upper-Middle Quarter: ≥ 18.3cm to < 20.7cm Upper Quarter: ≥ 20.7cm to ≤ 23.0cm Highest Octile: ≥ 21.9cm to ≤ 23.0cm
