简要总结
This study will test the accuracy of an investigational, non-invasive device for measuring heart rate and respiratory rate. The device emits radiowaves that allows it to pick up subtle changes in a person's chest wall, which allows it to calculate the heart rate and respiratory rate. We propose to study whether the device's measurements are accurate and reproducible in patients with chronic obstructive pulmonary disease (COPD) or asthma. The device undergoing study has been evaluated in healthy volunteers, but its accuracy in vital sign monitoring in patients with respiratory conditions has not yet been established. This study will serve as the foundation for additional work to assess the device's accuracy in measuring a patient's overall "work of breathing" or respiratory effort. Future work will examine the device's accuracy in measuring work of breathing in patients having an exacerbation of their underlying respiratory condition.
The primary aim of this study will be to assess the validity of heart rate and respiratory rate measurements in patients with either COPD or asthma.
