Estimation of alveolar pressure variations during panting.
Plethysmographic assessment ofthoracic gas volume (TGV), using Boyle’s law during panting against an occluded airway, necessitates an estimation of alveolar pressure variations (SPA). In the widely used method introduced by DuBois et al in 1956,’ mouth pressure variations ( Pm) are taken as an estimate of SPA. However, these authors noted that in the presence ofcheek movements “the change in mo...
متن کاملVariations in ocular pressure during menstrual cycle.
The present study investigated whether a correlation between days of the menstrual cycle and variations in intraocular pressure exists or not. The number of days since the beginning of last menses was recorded along with intraocular pressure for 1,459 women. Measurements were taken by Goldmann applanation tonometer. The differences among various days of menstrual cycle were statistically insign...
متن کاملVoicing variations in French obstruents: Distribution and acoustic quantification
This study investigates phonetic variation of voicing correlates in French obstruents. A controlled set of words was extracted from a large broadcast news corpus providing 378 word-initial singleton obstruents /t, d, k, s/. An expert investigation, by eye and ear, of the productions revealed that phonologically voiced obstruents are phonetically voiced most of the time (96%), while a large numb...
متن کاملRelationship between esophageal and alveolar pressure variations-during occlusion.
To the Editor: Failure of mouth pressure variations (APm) to reflect alveolar pressure variations (APA) during thoracic gas volume (TGV) measurements by Boyle’s law has been reported in asthmatic patients by Shore and Martin (1) and quite recently by Stanescu et al. (2). In both studies the conclusions were reached by comparing TGV’s obtained by relating plethysmographic volume changes (AVbox) ...
متن کامل[Middle ear pressure variations during anesthesia with nitrous oxide].
Some authors have reported that significant pressure changes occured in middle ear clefts when nitrous oxide (N2O) is inhaled during general anesthesia . In 18 adult patients without ear diseases who underwent non-otological surgery , middle ear pressure measurements were made with impedance audiometer (Teledyne TA-2C) just before and during N2O anesthesia. The results obtained were as follows:...
