Experimental study on human HRV under different ventilation conditions in aircraft cockpit

This study examines the effects of different ventilation environments in the cockpit on the physiological state of pilots by using the human heart rate variability (HRV) indexes. The experiment involved collecting HRV data from pilots in the cockpit under three different ventilation conditions using the HEXOSKIN physiological monitoring vest. The results showed significant differences in Parasympathetic Nervous System index (PNS), Sympathetic Nervous System index (SNS), Mean Heart Rate (HR), and Standard Deviation of NN intervals (SDNN) indexes among the different ventilation schemes. By comparing the changes in HRV indexes under the three different ventilation conditions, the optimal cockpit ventilation scheme was determined.
