Lung Function Changes with Acute +Gz Exposure as Assessed by Impulse Oscillometry.
Aerosp Med Hum Perform
January 2025
Introduction: The introduction of fifth-generation fighter aircraft has raised concerns regarding the impact of high gravitational forces on lung function. This study aimed to investigate the acute effects of controlled +Gz exposure, up to +9 Gz, on lung function in military pilots using impulse oscillometry (IOS).
Methods: These studies, conducted in Canada and the Netherlands, involved military pilots undergoing high G centrifuge training.
G-Induced Loss of Consciousness Prediction Using a Support Vector Machine.
Aerosp Med Hum Perform
January 2024
Gravity-induced loss of consciousness (G-LOC) is a major threat to fighter pilots and may result in fatal accidents. The brain has a period of 5-6 s from the onset of high +G exposure, called the functional buffer period, during which transient ischemia is tolerated without loss of consciousness. We tried to establish a method for predicting G-LOC within the functional buffer period by using machine learning.

Background: During flight, G force compels blood to stay in leg muscles and reduces blood flow to the heart. Cardiovascular responses activated by the autonomic nerve system and strengthened by anti-G straining maneuvers can alleviate the challenges faced during G loading. To our knowledge, no definite cardiac information measured using a mobile health device exists for analyzing G tolerance.

There are several injuries potentially related to high-G exposure, including neck and back pain, spinal fractures, and pneumomediastinum. We present a young military pilot diagnosed with isolated fractures of the right 9th and 10th ribs via X-ray after high-G exposure (maximum G level: 9G). This patient presented with progressive and localized pain in the right anterior chest and flank region.

Chronic changes in left ventricular (LV) hemodynamics, such as those induced by increased afterload (i.e., hypertension), mediate changes in LV function.
