Function Testing

Pulmonary function testing is a physiological test that measures the air volume that an individual inhales or exhales as a function of time. Smoking is greatly associated with reduction of pulmonary function. The aim of the present study was thus to estimate forced expiratory volume in first second (FEV1), forced vital capacity (FVC), and maximum voluntary ventilation (MVV) in adults aged ≥ 40 years with smoking history. Smoking is often related to obstructive disorders, as indicated by low FVC, FEV1, and MVV values. These pulmonary functions were analyzed based on several variables, such as number of cigarettes smoked per day, smoking duration and age. The study sample comprised of 100 healthy adult smokers. All participants were interviewed to obtain information related to their lifestyle and smoking habit. After analyzing the FVC, FEV1, and MVV results using SPSS software, we noted that their values were conversely related to participant age and smoking duration.

Function Testing

Spirometry, also called office-based pulmonary function testing, is a useful tool for diagnosis and classification of lung disease. Here, we outline a simple stepwise approach for interpretation of spirometry results. The first step is to determine the forced expiratory volume in a one second/forced vital capacity (FEV1/FVC) ratio. If airflow is limited, a bronchodilator is administered followed by reassessment. The next step is to determine whether FVC is low; an observed decrease in FVC indicates a restrictive patten. For patients with obstructive disease, inhalation medication is needed. Therefore, this review also describes the most appropriate inhalation device for each patient and the correct use of the device to maximize inhalation therapy benefits.

Background Although the close relationship between the upper and lower airways has been highlighted previously, little is known about the association between lung function and the recurrence of chronic rhinosinusitis with nasal polyps (CRSwNP). This study aimed to evaluate the factors associated with pulmonary function that affect CRSwNP recurrence after surgery. Methods We performed a series of routine pulmonary function tests for general anesthesia prior to CRSwNP surgery. The values for each parameter were compared in the presence or absence of recurrence. Results Sixty-nine patients with CRSwNP were included. The percent predicted forced expiratory volume in one second (%FEV1) in the recurrent group was significantly lower than that in the non-recurrent group ( P = .005). A multivariable logistic regression model revealed that %FEV1 was a positive predictor of recurrence (odds ratio: 0.96, 95% CI: 0.92-0.99, P = .023). There were no significant differences in the other pulmonary functions between the two groups. Conclusions We found that %FEV1 may be a predictor of CRSwNP recurrence after surgery. As %FEV1 is a pulmonary function test that is routinely performed before surgery, this parameter is readily applicable. Moreover, as %FEV1 appears to have the potential to reveal concealed asthma, %FEV1 might be a particularly useful tool for the prediction of CRSwNP recurrence after surgery.

The incidence of exercise-induced asthma (EIA) was studied in 134 asthmatic, 102 nonasthmatic atopic, and 56 nonatopic children. Pulmonary function tests measuring forced vital capacity (FVC) and one-second forced expiratory volume (FEV1) were performed on each child prior to and serially for 20 minutes following free running exercise. The incidence of EIA among the asthmatic and atopic nonasthmatic children was 63% and 41% respectively, and 7% among control subjects. Airway function was studied prior to and after a standardized free running exercise test. Forty-one percent of the nonasthmatic and 63% of the asthmatic atopic children had a significant decrease in airway function as compared to 5% of the nonallergic subjects.

Functional Indices

Although the general framework described in the joint American Thoracic Society/European Respiratory Society guidelines provides a useful and practical method for the interpretation of pulmonary function tests, several other measurements and functional indices, if understood correctly, may help in diagnosis and management of patients with respiratory diseases and in design of research protocols. This review provides information on the underlying physiology, interpretative caveats, and the evidence supporting the use of a number of these indices. Some of these measurements, such as the inspiratory fraction, inspiratory capacity/total lung capacity (IC/TLC), may offer additional prognostic information, while others, such as residual volume (RV)/TLC and forced expiratory volume in 3 s/forced vital capacity (FEV3/FVC), may help fill in the gaps between patient symptoms and more traditional indices of pulmonary function. Although most studies of non-traditional indices focus on airflow-limiting disorders, many can be fruitfully applied in other settings. Understanding the physiology that catalyzed these investigations will undoubtedly enrich the functional assessment armamentarium of the practicing clinician and researcher.

OBJECTIVES This study aimed to compare the change in pulmonary function in children and adolescents with cystic fibrosis (CF) who were infected with methicillin-resistant Staphylococcus aureus (MRSA) treated with either vancomycin (VAN) alone or vancomycin plus rifampin (VAN-RIF). METHODS Included patients were ages 6 to 20 years; hospitalized for an acute pulmonary exacerbation (APE) of CF from May 1, 2012, to April 30, 2014; had a respiratory tract culture positive for MRSA within 1 month of index hospital admission; received at least 48 consecutive hours of VAN or VAN-RIF; and had admission and discharge pulmonary function tests. The primary end point was change in percent predicted forced expiratory volume in 1 second (FEV1). RESULTS A total of 39 encounters met inclusion criteria: 24 in the VAN group (mean age 15.1 years) and 15 in the VAN-RIF group (mean age 13.7 years). There were no between-group differences in mean percent change in FEV1 (32.6% ± 28.8% vs. 21.1% ± 12.1%; p = 0.091), mean percent change in forced vital capacity (22.6% ± 25.8% vs. 14% ± 9.4%; p = 0.127), or return to baseline FEV1 (20 [83.3%] vs. 14 [93.3%] patients; p = 0.631). Median (IQR) length of stay (13 days [11–14 days] vs. 13 days [9–14 days]; p = 0.6) and median (IQR) time to readmission (82 days [43–129 days] vs. 147 days [78–219 days]; p = 0.2) were similar between the VAN and VAN-RIF groups, respectively. CONCLUSIONS Vancomycin monotherapy appears to be adequate when treating APEs of CF in children and adolescents with moderate lung disease and high MRSA VAN minimum inhibitory concentrations. Therefore, the addition of RIF may be unnecessary; however, larger studies are needed to confirm these findings.

Background: Air conditioners are used extensively these days of the modern lifestyle. Inhalation of cold dry air while using Air conditioners causes bronchoconstriction due to which alteration may occur in pulmonary function. This study was aimed to compare the Pulmonary Function tests of Car AC users and non AC users. Methods: The Study included 52 employees not exposed to car air conditioner as a control (group I) and 52 employees exposed to car air conditioner  with minimum exposure of 1 hour per day for 6 months as a subject (group II). Pulmonary function tests were performed using computerised spirometer. Statistical analysis was done by unpaired t test.Results: Age, Height and weight are not statistically significant between study group and control group. Forced vital capacity, forced expiratory volume in 1 second, Ratio of Forced vital capacity and Forced expiratory volume in 1 second, Inspiratory reserve volume, Expiratory reserve volume, Maximum voluntary ventilation are decreased in car air conditioner users compared to non-users, but was not significant. Forced expiratory flow (FEF), Peak expiratory flow rate (PEFR) values shows statistically significant decreased in car air conditioner users.Conclusions: The present study shows hyper-responsive airways on exposure to cold air which leads to bronchoconstriction. The significant decrease in PEFR, FEF suggest that upper airways as well as smaller airways are affected on exposure to car AC. So, Exposure to car Air Conditioner leads to risk of developing respiratory dysfunction.

Background: Previous studies suggest that obese individuals are prone to pulmonary function abnormalities. The aim of this study was to evaluate pulmonary function tests in obese individuals and to relate pulmonary abnormalities if any found to lipid abnormalities and to the extent and duration of obesity.Methods: This prospective study was done on 40 obese patients attending to Dr. D. Y. Patil Hospital, Mumbai with complaints of pulmonary functions during the period from January to December 2012. Pulmonary function test was done with the help of Jaegers pneumoscreen. The percentage of body fat was determined by using triceps skin fold thickness technique by using Vernier callipers. Fasting serum samples was collected to analyses cholesterol and triglycerides.Results: Female preponderance was seen in the study (57.5%). Forced expiratory volume, forced vital capacity, maximum mid expiratory flow rate was significantly reduced and the ratio of forced expiratory volume in one second to forced vital capacity was significantly increased in individuals who had abnormal pulmonary function. Decrease in pulmonary function was noted with increased levels of cholesterol and triglyceride but the correlation was not significant.Conclusions: Obese individuals although asymptomatic have significant lung function abnormality in the form of restrictive as well as obstructive pattern. Hence, reduction in the body weight may help in reversal of the pulmonary function indices.

A questionnaire was sent to all pediatric training programs to evaluate the use of pulmonary function reference standards and the interpretation of pulmonary function test results. Responses were obtained from 107 of 130 institutions, and 94 of these had pulmonary function laboratories available. Of the 94, 60 used one of three reference standards. The primary reason the reference standards were chosen was either unknown or because they came with the spirometer (24), were recommended by another person or were those used in that person's training (34), or were thought to be the best standards available or most applicable to the population to be tested (31). To define abnormality, most used an 80% predicted cutoff for forced vital capacity, forced expiratory volume in 1 second, and forced expiratory flow at 25% to 75% vital capacity. For a change in an individual through time, most used a 10% change for forced vital capacity, forced expiratory volume in 1 second, and forced expiratory flow at 25% to 75% vital capacity. Thirteen used statistical methods to define abnormal individuals and none used statistical methods to define a significant change over time. Although there are a few guidelines for reference standards and interpretations of pulmonary function tests, it appears that most laboratories are not using those guidelines and that further guidelines and education are needed.

Maximal Voluntary Ventilation

Ventilatory pulmonary function was investigated in 160 children and adults with repaired or unrepaired congenital cleft palate in comparison with 130 normal children and adults. Pulmonary function tests included measurement of lung volumes, of maximal voluntary ventilation (MVV) and of forced spirometry parameters: forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV1/FVC ratio and mean forced expiratory flow during the middle half of FVC (FEF25–75). Patients with cleft palate demonstrated significant differences from normal individuals in some of the measurements made. Functional alterations were observed at higher frequency among adult patients with unrepaired clefts and mainly consisted of a reduction in expiratory flows and MVV. However, the deviations observed were usually discrete and probably of low Physiopathologic significance. The results permit us to conclude that, in contrast to data reported by others, subjects with congenital cleft palate have little impairment of pulmonary ventilatory function.
