Hemodynamic characteristics of postural hyperventilation: POTS with hyperventilation versus panic versus voluntary hyperventilation

Hyperventilation in postural hypotension.

Voluntary hyperventilation in obesity hypoventilation.

Arterial blood gas analysis was performed before and after 60 to 90 s of voluntary hyperventilation in 27 consecutive patients with occlusive sleep apnea syndrome (OSA) and daytime hypercapnia. The percentage of fall in PaCO2 from baseline was examined in relationship to age, body mass index, sleep-disordered breathing indices, and pulmonary function variables. In 14 subjects without airflow ob...

Hyperventilation symptoms and their relationship to panic

Symptom overlap between the Hyperventilation Syndrome (HVS) and Panic Disorder (PD) has been noted by many investigators; however, the reasons for this association are unclear. By following 50 college subjects (36 fema le and 14 male) who displa yed extremely high rates of hyperventilation symptoms over four-week to nine-month intervals, symptom stability patterns as well as the relationship to...
