Telemedicine techniques could deliver health care services to battlefields and expedite, optimize patient care and triage. However, the communication networks in such environments are often unreliable and have limited bandwidth. In this study, we evaluated the accuracy loss and clinical decision error caused by data transmission. We compared physiologic data under various resampling rates with the original high-resolution data and reported the matrix to detailed trade-off between clinical accuracy and band resource requirement. Using data collected from 15,000 trauma patients, we found that heart rate readings could be within a 10 difference when reducing sampling rate from 2 seconds to 5 minutes. Moreover, the high-fidelity waveform could be reduced for sampling rate with a small 5 loss in prediction performance. This study could guide optimal selection of data sampling rate and estimation of data reliability based on the wireless bandwidth availability and acceptable vital signs resolution during the remote clinical decision making process.
