Abstract:
Studies of empathy show that seeing another person in pain, fear or disgust elicits the same brain activations associated with pain, fear or disgust in oneself. Our interest is to know whether respiratory change can be observed in empathy, that is, whether respiration can be altered when observing emotions in others. A discomfort associated with respiration can be breathlessness. We investigated respiratory pattern and metabolic response during observation of a breath-holding subject. We found that breathlessness occurred in participants who observed breath-holding in another person. It is interesting to note that observers felt more breathlessness after breath-holding ended with an increase in respiratory rate consistent with the breath-holder's respiratory pattern. In addition, observers with high trait anxiety felt more breathlessness accompanied with an increase in respiratory rate. An increase in respiratory rate may be involved in the perception of breathlessness, in addition to the effect of observing breath-holding, indicating shared negative emotion.

Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
