Background: Previous studies have been reported that about 80% of women experience premenstrual syndrome (PMS) during luteal phase of menstrual cycle. Normally menstruating women show hypocapnia followed by increased ventilation due to increased progesterone during the luteal phase compared follicular phase . As specific reason for PMS has not still been proved, various theories have been revealed and hence for PMS specific treatment is still not available. Aim: To assess the effect of End…

Status of pulmonary function tests in adolescent females of Delhi.

The majority of pulmonary functions reflect better values in luteal phase as compared with follicular phase however, a statistically significant higher results of FVC, FIVC, FEV1, and TLC were noticed in group I and group III, suggesting a possible role in increased level of progesterone in lutenal phase on respiratory system.

Autonomic function tests during pre and post menstrual phases in young women.

Responses to various sympathetic tests were significantly altered in premenstrual phase as compare to that of postmenstruAL phase reflecting the significant increase in the sympathetic activity.

Effect of medroxyprogesterone on ventilatory control and pulmonary gas exchange in chronic obstructive patients.

It is concluded that MPA lowers the PaCO2 of hypercapnic chronic obstructive pulmonary disease patients through an increased tidal volume, which could result from an increased central nervous inspiratory output, or from better mechanical performance of the respiratory muscles due to the same central stimulation.

Slow Recovery From Voluntary Hyperventilation in Panic Disorder

PD and SP patients report more distress than controls to equal amounts of hypocapnia, but PD differ from SP patients and controls in having slower symptomatic and physiological recovery.

The effect of acetazolamide on ventilation in panic disorder patients.

The authors replicated the earlier finding that acetazolamide is not panicogenic in patients with panic disorder but also showed that at the dose given, there is no meaningful effect on ventilation.

Breathing retraining: effect on anxiety and depression scores in behavioural breathlessness.

Brain pH response to hyperventilation in panic disorder: preliminary evidence for altered acid-base regulation.

Although subjects with panic disorder had greater hypocapnea during hyperventilation, their observed pH response, not altered from comparison levels, implicated exaggerated buffering, and it is suggested that increased lactate could account for these findings.

Respiratory Ventilation and Carbon Dioxide Levels in Syndromes of Depression

It has been shown that breathing rate goes up and PCO2 down in non-retarded and neurotic depression and with schizophrenia, and it must lead to alterations in pH and other variables.

The role of hyperventilation: hypocapnia in the pathomechanism of panic disorder.

A profile of panic disorder based on and generalized from the effects of acute and chronic hyperventilation that are characteristic of the respiratory panic disorder subtype is presented.

Analysis of end-tidal and arterial PCO2 gradients using a breathing model

Analysis of the PETCO2-PaCO2 difference between experimental and sinusoidally adjusted ventilatory flow profiles at rest and during exercise showed that the model produced similar values in PET CO2- paCO2 for different respiratory flow dynamics, similar to data published by Jones et al.
