Hyperventilation can be caused by things like exercise, anxiety, or asthma. Hyperventilation changes haemodynamic function through central and peripheral mechanisms; its effects on colonic motor function, however, are unknown. Without treatment it can lead … Symptoms attributable to hyperventilation are common among patients with the irritable bowel syndrome (IBS); indeed, some have suggested that hyperventilation may exacerbate the alimentary symptoms of IBS. The aim of this study, therefore, was to assess the effects of hyperventilation on colonic tone and motility and on cardiovascular autonomic activity, and to discover if hypocapnia was critical to elicit the response. The aim of this study, therefore, was to assess the effects of hyperventilation on colonic tone and motility and on cardiovascular autonomic activity, and to discover if hypocapnia was critical to elicit the response. Phasic and tonic motility of the transverse and sigmoid colon, end tidal PCO2, pulse rate, and beat to beat pulse variability were assessed before, during, and after a five minute period of hypocapnic hyperventilation in 15 healthy volunteers; in seven other subjects, effects of both eucapnic and hypocapnic hyperventilation were evaluated.

Hyperventilation changes haemodynamic function through central and peripheral mechanisms; its effects on colonic motor function, however, are unknown. Obesity hypoventilation syndrome is a breathing disorder that affects some people who have been diagnosed with obesity.

COVID-19 is an emerging, rapidly evolving situation. and Hanson, {R. 2010 Oct;48(10):718-33. doi: 10.1038/sc.2010.14. Hyperventilation syndrome reduces blood supply and oxygen levels for all vital organs of the human body. When necessary, treatment may also include a medical device called an implantable cardioverter-defibrillator (ICD). Management can be difficult, and the process of making this diagnosis, largely through the exclusion of other disorders and recognizing its specific features, is covered. Hypocapnic but not eucapnic hyperventilation produced an increase in colonic tone and phasic contractility in the transverse and sigmoid regions and an increase in pulse rate and pulse interval variability. The findings are consistent with inhibition of sympathetic innervation to the colon or direct effects of hypocapnia on colonic smooth muscle, or both.

The aim of this study, therefore, was to assess the effects of hyperventilation on colonic tone and motility and on cardiovascular autonomic activity, and to discover if hypocapnia was critical to elicit the response.
