Abstract: Objectives: To evaluate the accuracy of heart rate and respiratory rate acquired by commercially-available device cameras and software. Methods: One-hundred and eleven subjects were enrolled at an urban academic teaching hospital in Texas. Heart rate (HR) and respiratory rate (RR) measurements were obtained using three commercially-available cameras and processed using software from Presage Technologies. These values were compared to manual counts of a three-lead ECG and end-tidal CO2 from a patient monitor. Results: The cameras were able to capture HR in 83% of the measurements and RR in 94% of the RR measurements. Camera-acquired HR showed an extremely high correlation with R∼0.99 and a root-mean-square error (RMSE) of 1.62. Respiratory rate showed a high correlation with R∼0.91 and an RMSE of 1.71. Conclusions: Heart rate and respiratory rate can be accurately acquired using commercially-available camera devices and software for signal processing.
