Use of Inspiratory Minute Volumes in Evaluation of Rotary and Fixed Wing Pilot Workload.

摘要

Inspiratory minute volume (IMV) measurements by Mueller Respirometer were utilized in the evaluation of US Army aircrew workload and stress in helicopter and fixed wing aircraft. The IMV data obtained demonstrates a significant stress and/or workload level of the aviator in performance of helicopter day nap-of-the-earth (NOE), night nap-of-the-earth (NNOE) and with the use of night vision devices (NVD). IMV of 20.05 to 38.11 liters per minute NTPD were obtained during the performance of these combat operational techniques. IMV determination in-flight is considered a valuable clinical tool in the assessment of aircrew stress and/or workload. (Author)
