The meaning of SPIROMETER is an instrument for measuring the air entering and leaving the lungs (as in determining lung function in the diagnosis of pulmonary disease).
Obstructive airway disease (OAD) was defined as FEV1/FVC<0.70 & PRISm was identified as FEV1/FVC 鈮 0.70 and FEV1<80% predicted.Results: Among 3402 subjects, interim analysis is presented for 1682 subjects. 588 (35%) had presence of respiratory symptoms (cough, breathlessness, wheeze) or ...
Observed agreement is defined as the number of tests on which the raters agree with each other divided by the total number of tests (a + d/N). Agreement with Cohen’s kappa is interpreted as described by Landis and Koch28: κ > 0.81 is considered a good agreement, κ >...
However, the radiologist did not mention the grade or severity of the atelectasis, but they divided them to is present if atelectasis present or not, also knowing that the radiologist was blinded about the intervention or control group, also atelectasis defined as the collapse of a part of or...
Peak Expiratory Flow (PEF) is the maximum flow attained during an FVC maneuver (expressed as L/s or L/m). Peak Flow Meter may be used at the bedside, ER, clinic setting, or at home. FVC : Patient should ___, ___inspiration with a ___ expiration (1-2 seconds) stand maximal ...
For example, “Sex” is a nominal variable; in the “Label” column, it is labeled as “Sex” (male or female). In the “Values” column, the coding is provided as 0 = female and 1 = male. The “Variable View” tab in the SPSS file of comprehensively explaining each variable and...
Spirometry should be used to confirm a diagnosis of chronic obstructive pulmonary disease (COPD). This test is not always performed, leading to possible misdiagnosis. We investigated whether the proportion of patients with diagnostic spirometry has increased over time as well as factors associated with...
The main strength of the technique is to be based on 3D motion corrected MR images, namely on complete 4D MR dataset. As seen above, the parameters we have explored can be quantified, first, everywhere in the lung, second upon the actual 3D motion field of the lung parenchyma. The latter...
It is also possible to rule in asthma. However, it was impossible to rule out asthma as the sensitivity was too low. The prevalence of COPD is increasing in nearly all countries of the world and a high diagnostic accuracy is a prerequisite of optimal therapeutic management. The important ...
While current clinical practice is based on manual disposable incentive spirometers, others have disclosed devices and methods to provide other kinds of patient visual feedback and encouragement such as animated figures, images which are gradually unveiled, or other patterns [Vilozni 2003], [Quinn 20...
