Vital Signs Analysis for Oceanauts in Deep Sea Submerged Environment: A Case Study
The oceanauts often suffer a lot from psychological dysfunction in the narrow and complicated deep sea environment. This paper aims to analyze the vital signs for oceanauts in submergence work with one case as an example. Four vital signs including heart rate, blood pressure, SDNN and LF/HF derived from ECG and blood pressure signals were analyzed to demonstrate the physiological status in submergence work.
