  2. 1. Ventilation distribution in the lung periphery measured by inert gas washout : influence of increased gravity, anti-G suit pressure, body posture, and breathing pattern

    Abstract : The lung is highly sensitive to forces of gravity and acceleration, and to surrounding pressures. This thesis aimed to assess the effects on ventilation distribution in peripheral lung units when changing the direction or magnitude of the gravitational vector and when compressing the lower body half with an anti-G suit (AGS).

  4. 2. Lung function in micro- and in hypergravity

    Author : Stéphanie Montmerle; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Lung physiology; human; spirometry; rebreathing; cardiogenic oscillations; phase IV; anti-G suit; stroke volume; weightlessness; closing volume; DLCO;

    Abstract : The lung is extremely susceptible to gravity, even during short-term changes of the gravity vector, because it is a mixture of air and elastic tissue components. Yet, there is limited knowledge of the effects of gravity on the respiratory system. READ MORE
