This study is designed to be a clinical validation study to ready the CPM System for FDA 510(k) submission. This study will be conducted as a prospective non-randomized. The study is non-significant risk since the CPM Device is noninterventional and noninvasive. The study is primarily designed to validate the accuracy of the respiration rate and the changes in relative tidal volume. All participants will be fitted with both the CPM Device as well as reference devices (capnography and ECG). Participants will be randomized between 4 procedures (A-D) which will determine the order of 18 exercises. Each exercise has about 2 minutes of device recording and two minutes of rest. Each exercise contains two positions: sitting up for one minute and lying down for one minute. For some exercises, the participant will be instructed to breathe at a certain rate (assisted by a metronome). For other exercises, the participants will breathe at a normal rate but change how deep the are breathing. For exercise 18, all capnography reference devices will be removed, and an ECG reference device will be placed. After exercise 18, the participant will have all devices removed and the study visit will terminate. The participant will receive a safety follow-up call about 1 week after their visit.

| Accuracy of CPM System Calculated RR Versus Reference Device Via Percent of Error Accuracy of Respiration Rate | Accuracy of CPM System calculated RR versus reference device reported as percentage of respiration rate error within +/- breath rates per minute. Acceptance for clinical utility is >= 85%. Percentage of respiration rate error within ± 2bpm. Acceptance criteria for clinical utility is >= 85%. The percentage of respiration rate within ± 2brpm was calculated by data points, regardless of its rate and breathing condition, which the CPM System did not screen, therefore reporting the numeric values. Each data point will produce binary result (True or False) if the error is within ± 2 brpm. Assuming this binary result follows a binominal distribution, its confidence interval is also calculated. | up to 3 hours |
| Root Mean Squared Error (RMSE) of Respiration Rates From the CPM System vs Reference Device for Metronome Guided Breathing and Non-metronome Guided Breathing. | Root mean square (RMS) of residual relative error of relative tidal volume. Acceptance criteria for clinical utility is <= 35%. First, the subject-specific linear fitting is performed after taking the natural log of both CPM's rTV and reference TV. Then, the residual errors in rTV after the fitting were calculated. Finally, all subject's residual errors are pooled together to calculate the root mean squared (RMS) residual relative errors. The confidence interval was calculated assuming the square of this error follows Chi-square distribution. This error characterized in a log-log domain is converted back to characterize a relative accuracy by taking an exponential of natural constant followed by subtraction of one. The RMS of residual error in % is characterized in this way because the linear fitting in the log-log domain and its residual errors represents faithful relative residual error regardless of an absolute value of TV. | up to 3 hours |

| Accuracy of CPM System Calculated Respiration Rate Versus Reference Device, Reported as Root Mean Squared (RMS) Error | Accuracy of CPM System calculated RR versus reference device. It is reported in Root Mean Squared error for both exercises with metronome guided breathing and non-metronome guided breathing. Acceptance criteria of substantial equivalence is ~1.6 breath rates per minute (BRPM) for metronome guided breathing and 3.0 BRPM for non-metronome guided breathing. |
