Background And Methods:
Little is known about self-induced cognitive trance (SICT) on respiratory function. The aims of this prospective, single-center, non-randomized, open-label study of healthy volunteers, were to characterize spirometry changes during SICT, confirm the safety of this technique, and investigate the potential clinical benefits of SICT.
Results:
Nine people participated. There were no significant difference in FEV1 FVC or FEF 25-75 before, during, and after SICT. There were significant improvements in grip strength during SICT (+2.2 kg/5.7 %, p<0.05) and in self-efficacy score related to physical activity at the end of the trance. One participant had a significant worsening of FEV1 during SICT in the context of a recent upper airway infection.
Conclusion:
SICT does not significantly modify spirometry data in healthy volunteers and can improve self-efficacy related to physical activity. SICT should probably be performed with caution during upper airway infections.

Physiological Control of Respiration
Breathing, a seemingly passive process, is regulated by the respiratory center in the brainstem. This center coordinates the involuntary control of respirations, which means it occurs without conscious effort, ensuring a smooth and uninterrupted pattern.
Regulation of Ventilation
The body maintains ventilation by monitoring levels of carbon dioxide (CO2), oxygen (O2), and hydrogen ion concentration (pH) in the arterial blood. Among these factors, the level of CO2 plays a crucial...

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:
