Peak expiratory flow is not a quality indicator for spirometry: peak expiratory flow variability and FEV1 are poorly correlated in an elderly population. Chest. 2007;131(5):1494-1499.Hegewald MJ, Lefor MJ, Jensen RL et al. Peak expiratory flow is not a quality indicator for spirometry: peak...
We dichotomized spirometry measures as impaired, based on the values predicted for children residing in northeastern China (Ma et al. 2013): lung function as FVC < 85% of reference (FVC < 85%), FEV1 < 85% of reference (FEV1 < 85%), maximum mid expiratory flow < 75% of reference (...

Flow chart Full size image Six-minute walking test The 6MWT was carried out on a straight aisle with smooth surface and of 30 m long. Before the exam, the patients rested in a sitting position, during which spirometry was performed to assess pulmonary function, including the flow volume and...
Peak inspiratory flow rates should be measured via spirometry in all goiters to assess the degree of tracheal compression. Once tracheal compression is identified, an elective total thyroidectomy should be performed to prevent morbidity and mortality from acute airway obstruction.Drainage in thyroid ...
Mutations in GBA1, the gene encoding the lysosomal enzyme β-glucocerebrosidase (GCase), which cause Gaucher’s disease, are the most frequent genetic risk factor for Parkinson’s disease (PD). Here, we employ global proteomic and single-cell genomic app

Fill in the blank. The flow-volume loop is a ___. Spirometry: Spirometry is a test that relates with the access of measuring the functioning of lungs based on inhalation and exhalation of an individual. It is used to diagnose respiratory diseases like asthma, and other chronic obstructive...
The investigators were not blinded to the group allocation (TBC1D4 variant versus control) because all study participants were genotyped before entering the study. Part of the data collection was performed blinded including blood analyses of hormones, enzyme activities, mitochondrial respirometry, GLUT4...
1 a flow/volume curve at the first pulmonary function test; b flow/volume curve after 1 month of therapy signs. A cycle of inhalation therapy with LABA and inhaled steroid was started. After 1 month of therapy, the patient was still complaining dry cough. A new spirometry showed findings ...
