Validation of Respiratory Rate and Heart Rate Measurements by Capaciflectors Placed in Four Locations on the Chest

In a collaborative project between University Hospital Southampton NHS Trust and the University of Southampton, the investigators have developed a wearable, mobile, non invasive, low-cost, continuous respiratory rate monitor device called a capaciflector. This study will be the first ever study undertaken to attempt to measure the respiratory rate and heart rate on patients using a capaciflector. Investigators will evaluate whether the correlation between the capaciflector's measurements of respiratory rate and heart rate when compared with the gold standard pneumotachometer and electrocardiogram respectively is high enough to promote its potential future use within a device for clinical practice.
