The maximal expiratory flow-volume curve in normal subjects in India.
Data on pulmonary function, with particular reference to flow-volumes, were obtained in 760 normal healthy Indians in Bombay, who had never smoked and who had no symptom or history of cardiorespiratory disease. Prediction equations were derived for spirometric parameters and for maximal expiratory flows. The maximal expiratory flow-volume curves showed considerable intersubject variability. Bot...
متن کاملZero expiratory pressure and low oxygen concentration promote heterogeneity of regional ventilation and lung densities
BACKGROUND It is not well known what is the main mechanism causing lung heterogeneity in healthy lungs under mechanical ventilation. We aimed to investigate the mechanisms causing heterogeneity of regional ventilation and parenchymal densities in healthy lungs under anesthesia and mechanical ventilation. METHODS In a small animal model, synchrotron imaging was used to measure lung aeration an...
متن کاملInvestigation of ANP Plasma Concentration in Normal Pregnancy and Preeclampsia
با وجود شواهد روزافزونی که بیانگر نقش احتمالی ANP در هموستاز طبیعی مایعات بدن است، اما هنوز اهمیت نقش این پیتید در سلامت و بیماری بدرستی مشخص نیست. بر اثر ازدیاد فشار دهلیزی و تعداد انقباضات آن، ANP از میوسیت های دهلیزی ترشح می شود. تزریق مقادیر زیادی از ANP صناعی به انسان و حیوان سبب کاهش فشار سیستمیک دهلیزی و افزایش دفع سدیم و برقراری دیورز می گردد. مطالعات اخیر بر روی تأثیر تزریق ANP صناعی ...
متن کاملValidity of Peripheral Capillary Oxygen Saturation and Normal Mixed Venous Oxygen Tension in Measurement of O2 Content
Background The change in venous oxygen saturation occurs earlier, and even its reduction is faster than arterial oxygen saturation. The aim of this study was to validate SvO2 and PvO2 for O2 content measurement in children hospitalized w...
متن کاملForced expiratory indices in normal Libyan men.
Forced vital capacity (FVC), forced expiratory volume in one second (FEV1), forced expiratory ratio in the first second (FEV1% VC), forced expiratory flow between 200 and 1200 ml (FEF200-1200), and forced mid expiratory flow between 25% and 75% of FVC (FMF) were measured in 275 Libyan men ranging from 20 to 60 years. All values were lower with increasing age and, apart from FEV1% VC, were posit...
