Chest wall distortion during resistive inspiratory loading.

E R Ringel, S H Loring, J Mead

    Journal of Applied Physiology (Bethesda, Md. : 1985)
    |May 1, 1985

    Summary

    Breathing with added resistance causes varied chest wall movements. Muscle activity and pressure data do not fully predict these complex, often behavioral, respiratory responses.

    Area of Science:

    • Respiratory Physiology
    • Biomechanics of Breathing

    Background:

    • Inspiratory loading alters respiratory mechanics.
    • Understanding chest wall motion during loaded breathing is crucial.

    Purpose of the Study:

    • To investigate chest wall motion patterns under inspiratory resistive loads.
    • To explore the relationship between muscle activity, pressures, and chest wall configuration.

    Main Methods:

    • Six subjects (1 naive, 5 experienced) breathed with added inspiratory resistance.
    • Measurements included chest wall motion (rib cage, abdomen), tidal volumes, pressures (transdiaphragmatic, pleural), and muscle electromyography.

    Main Results:

    • Varied inspiratory motion patterns were observed based on subject instructions.
    • Predicting chest wall configuration from individual muscle contributions and pressures proved difficult.
    • Respiratory responses to loading showed substantial individual variability.

    Conclusions:

    • Chest wall distortion during loaded breathing is complex and influenced by behavioral factors.
    • Overall respiratory motion is not easily inferred from electromyographic and pressure data alone.
    • Individual responses to inspiratory loading are highly variable.
