Jan 27, 2018 · Pulmonary fibrosis prognosis is the prediction of the course of the disease, pulmonary fibrosis. It damages the interstitial lungs and the fibrosis and consequently the elasticity of the lungs is lost. This article provides some information on the prognosis of this medical condition.
A simple, practical method is described for estimating unilateral lung function. Overall lung function is plied by right-left fractional perfusion estimated from a quantitative technetium ferric hydroxide macroaggregate lung scan. The calculated function attributed to the lung to be resected is then subtracted from the overall pulmonary function.

[PDF]The paediatric calculation (for ages below 15 years) is taken from Lung Function by J E Coates (Fourth Edition): PEF = 455 x (height/100)-332. In 2004 the Department of Health initiated a change to PEF meters to align to those that met a new EC standard.
With the advent of automated pulmonary function machines, laboratories have to decide which prediction equations to use from the selection provided by the manufacturer. Few laboratories are sufficiently informed about the alternatives, and in practice many use the manufacturer's default choice.
Prediction of pulmonary function abnormalities after adult respiratory distress syndrome (ARDS). Elliott CG, Rasmusson BY, Crapo RO, Morris AH, Jensen RL. To determine if measures of ARDS severity during the acute illness correlate with lung function after recovery from ARDS, we regressed lowest total thoracic compliance (CTH), initial ...
Pulmonary Function Test Definition Pulmonary function tests are a group of procedures that measure the function of the lungs, revealing problems in the way a patient breathes. The tests can determine the cause of shortness of breath and may help confirm lung diseases, such as asthma, bronchitis or emphysema. The tests also are performed before any major ...
The pulmonary consequences of neuromuscular weakness result from impaired function of respiratory muscles and spinal deformity (1, 2). The impact on pulmonary function depends on the pattern of involvement and the rate of progression of the underlying disease (3–6). Outcome is related to the rate ...
Our purpose was to determine whether the risk of death due to respiratory failure could be predicted one or two years in advance on the basis of pulmonary function, blood gas levels, and ...
[PPT]Pulmonary function tests (PFTs) are non-invasive tests that show how well the lungs are working. Pulmonary function tests (PFTs) are non-invasive tests that show how well the lungs are working. Open the Johns Hopkins Medicine menu with the enter key and .
Prediction of Pulmonary Function in Patients with Chronic Obstructive Pulmonary Disease: Correlation with Quantitative CT Parameters Hyun Jung Koo, MD1, Sang Min Lee, MD1, Joon Beom Seo, MD1, Sang Min Lee, MD1, Namkug Kim, PhD2, Sang Young Oh, .
Pulmonary function test (PFT) is a complete evaluation of the respiratory system including patient history, physical examinations, and tests of pulmonary function. The primary purpose of pulmonary function testing is to identify the severity of pulmonary impairment. Pulmonary function testing has diagnostic and therapeutic roles and helps clinicians answer some general questions about patients ...
component.1 These spirometry data were used to generate age, gender, and race/ethnicity specific prediction equations for normal spirometric values.2 These reference standards have been widely used in research relating to occupational pulmonary disease, the effects of air quality on spirometric function.
We requested specific citations for the prediction equations used for spirometry, lung volumes, carbon monoxide diffusing capacity, and airway resistance. We also asked for a description of how they dealt with ethnic differences in pulmonary function. A follow up request was sent to institutions which had not responded to the first inquiry. Results

More recently, the inverse correlation between lung function and nutrition-that is, that improved nutrition status can positively affect pulmonary decay-was established. In support of that correlation, it has been shown that aggressive nutritional intervention improves, stabilizes, or slows the rate of pulmonary function decline.
Idiopathic pulmonary fibrosis (IPF) is the most common of the idiopathic interstitial pneumonias and carries the worst prognosis, with median survival ranging from 2.5 to 3.5 years (1, 2).Although IPF has an overall poor prognosis, the clinical course of individual patients varies from slow progression to acute decompensation and death (3, 4). ...
Jul 01, 2010 · Reliable interpretation of pulmonary function results relies on the availability of appropriate reference data to help distinguish between health and disease and to assess the severity and nature of any functional impairment. The overwhelming number of published reference equations, with at least 15 published for spirometry alone in the past 3 yrs, complicates the selection of an appropriate ...

Notes. Equation parameters such as Race, have two or more discrete values that may be used in the calculation.The numbers in the parentheses, e.g. (1), represent the values that will be used. The residual standard deviation (RSD) for FEV1 is 0.38 litres.; For FVC, the RSD is 0.38 litres and for the FEV1/FVC Ratio, the RSD is 6.51%.
[PDF]Mar 01, 2014 · Office-based pulmonary function testing, also known as spirometry, is a powerful tool for primary care physicians to diagnose and manage respiratory problems. An .
interpreting pulmonary function tests that will allow him or her to recognize and quantitate abnormalities. Before interpreting the results, one should ascertain that the test was acceptable and reproducible and that the patient's demographic data are correct. Pattern recognition is key.A low FEV
[PDF]the study for the prediction of the postnatal pulmonary function was calculation of observed to expected lung–head ratio (O/E LHR) using the contralateral lung tracing [ 5 – 7 ].
Purpose. It is important to accurately predict the patient's postoperative pulmonary function. The aim of this study was to compare the accuracy of predictions of the postoperative residual pulmonary function obtained with three-dimensional computed tomographic (3D-CT) volumetry with that of predictions obtained with the conventional segment-counting method.
