Summary
This study presents a system to detect gravity-induced loss of consciousness (G-LOC) using physiological factors. It also explores methods to improve pilot recovery and monitor anti-G systems.
Area of Science:
- Aerospace Medicine
- Human Factors Engineering
- Physiological Monitoring
Background:
- Gravity-induced loss of consciousness (G-LOC) poses a significant risk in high-performance aircraft.
- Existing monitoring systems require enhancement for real-time detection and intervention.
Purpose of the Study:
- To present the development status of a G-LOC detection system.
- To investigate physiological indicators for monitoring G-LOC.
- To explore methods for improving pilot recovery and monitoring aircraft systems.
Main Methods:
- Investigating physiological factors: eye blink rate, head slumping, arterial pulsations, and EEG spectral shift.
- Developing systems to detect anti-G straining maneuver and anti-G suit function.
- Considering voice-synthesized queries for pilot interaction.
- Exploring methods to reduce post-recovery incapacitation.
Main Results:
- The Loss-of-Consciousness Monitoring System (LOCOMS) is under development.
- Multiple physiological parameters are being evaluated for G-LOC detection.
- Integration of anti-G system monitoring and pilot interaction is being studied.
Conclusions:
- The LOCOMS aims to provide early detection of G-LOC.
- Comprehensive monitoring includes physiological data and aircraft system performance.
- Future work may reduce pilot incapacitation periods.

Direct Method
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...

01:30Pulse rhythm
Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac muscle...
