This study reveals that breath depth sensation relies more on proprioceptive signals than visceroceptive ones, influencing respiratory drive. Accuracy in rating breath depth varies with breathing conditions and demographics.

Area of Science:

  • Respiratory Physiology
  • Sensory Perception

Background:

  • Understanding the sensory mechanisms underlying breath depth perception is crucial for respiratory control research.
  • Previous studies have explored factors influencing respiratory sensation, but the precise interplay of sensory inputs remains debated.

Purpose of the Study:

  • To investigate the subjective assessment of breath depth and its relationship with tidal volume under various respiratory conditions.
  • To determine the primary sensory modalities (proprioceptive vs. visceroceptive) contributing to breath depth sensation.
  • To examine the influence of breathing condition, exercise, and demographics on breath depth perception accuracy.

Main Methods:

  • Magnitude production testing was employed to quantify subjective breath depth ratings.
  • Tidal volumes were measured concurrently with subjective ratings in subjects at rest (spontaneous and assisted breathing) and during mild exercise.

  • Stevens power function was used to analyze the relationship between subjective breath depth and objective tidal volume.

    • Main Results:

    • Breath depth assessment was most accurate during spontaneous breathing at rest (Stevens exponent ~0.94).
    • Assisted ventilation led to less accurate ratings, with a tendency to underestimate breath depth.
    • Subjects tended to overestimate voluntary reductions in tidal volume, particularly young women.
    • During exercise, both increases and reductions in tidal volume were overestimated.
    • Voluntary tidal volume modifications triggered compensatory changes in breathing timing and rapid recovery of tidal volume.

    Conclusions:

    • Breath depth sensation is predominantly driven by proprioceptive signals from respiratory muscles, rather than visceroceptive signals.
    • The autonomous respiratory drive is influenced by breath depth sensation, with proprioception playing a role in its control.
    • Demographic factors and breathing conditions significantly modulate the accuracy of breath depth perception.
