Formal
spirometry forms an integral part of the diagnosis and management of patients with asthma and COPD and relies on a competent operator, accurate equipment, standardised operating procedures, quality control and patient co-operation as outlined in the South African guideline for office
spirometry.
If COPD is suspected, perform
spirometry to determine the presence of fixed airflow limitation and confirm the diagnosis.
All these patients underwent
spirometry. Patients were evaluated for forced vital capacity (FVC), forced expiratory volume in 1 s (FEV-1), and the ratio of both FEV-1 and FVC.
Spirometry variables including forced vital capacity, forced expiratory volume in 1 second, ratio between the two, peak expiratory flow rate, forced expiratory flow between 25% and 75% expired volume were recorded and interpreted.
The GOLD 2017 classification simplified the chronic obstructive pulmonary disease staging that was available from 2011 to 2015 from three variables (
spirometry thresholds, exacerbation risk, and dyspnea scale) to two variables (exacerbation risk and dyspnea scale).
So it's necessary to update the reference ranges for
spirometry and its prediction equation as well.
To assess the baseline pulmonary function by
spirometry in newly diagnosed hypothyroid patients not having any known lung diseases.
Any patient unable to perform
spirometry, recently diagnosed smear positive pulmonary tuberculosis (PTB), recent myocardial infarction and any infectious disease patient were excluded.
Therefore, this study aims to analyze the relationship between the presence of DOH and the number of attempts of forced
spirometry maneuvers performed by healthy children.
Spirometry tests measures the total amount of air you can breathe out from your lungs and how fast you can blow it out.
Findings also show that just 54.3% of patients diagnosed within the past two years had a record of any
spirometry test with a result consistent of COPD.
The Global Initiative for Chronic Obstructive Lung Disease (GOLD) has uncoupled
spirometry results from the ABCD treatment algorithm; this move marks the organization's first announcing of major COPD guidance since 2011.
Spirometry is a valuable tool for the diagnosis and follow-up.
Spirometry is essential in early diagnosis, as symptoms are not always a reliable indicator of COPD [8].
