Peak Expiratory Flow Rate in Healthy Children from Tehran
Background: Measuring peak expiratory flow rate has been suggested as an important tool in asthma management by all international guidelines. Objective: Studies on various populations have shown considerable variations in normal values of peak expiratory flow rate. Since reference standards for Iranian children are not available, the present study was performed to establish these standards. Me...
متن کاملInstantaneous Blood Flow Responses
Variable hemodynamic responses to positive end-expiratory pressure (PEEP) with spontaneous ventilation have been reported. To clarify these responses, 15 awake patients were studied using a catheter-tip velocity transducer to record phasic aortic root blood flow continuously before, during and after PEEP (10 cm H20) applied with a face mask. Central blood volume and effective ventricular fillin...
متن کاملComparison of peak flow gauge and peak flow meter.
A comparison has been made of the new peak flow gauge and the Wright peak flow meter. Close correlation was found between measurements made with the two instruments both in normal subjects and in patients. The peak flow gauge is as consistent as the peak flow meter but is cheaper and more portable. It should be useful in survey work in general practice and for loan from hospital outpatient depa...
متن کاملPeak Angiogram Calculations from 4D Flow Imaging
Introduction Cine 4D flow imaging allows not only for the assessment of cine velocity fields but also for the generation of angiograms. We have adopted this approach with a radially undersampled phase contrast acquisition, PC VIPR, to provide a non-contrast enhanced MRA alternative for patients with a contra-indication for CE MRA based on Gd injections [1]. We have adopted a modified complex di...
