Function Tests

The main elements of a chest assessment are outlined. Elementary measurements which should be taken by physiotherapists are described. Simple lung function tests which are within the capability of physiotherapists who are closely concerned with chest patients are explained in some detail. The tests concerned are: Peak Expiratory Flow Rate, Forced Vital Capacity, Forced Expiratory Volume in 1 sec. and the ratio Forced Expiratory Volume in 1 sec./Forced Vital Capacity as a percentage. Four of the more advanced tests and their underlying concepts which are more the domain of special pulmonary testing laboratories are briefly described.

ABSTRACT Objective: To evaluate the change in respiratory function and functional capacity according to the type of preoperative fasting. Methods: Randomized prospective clinical trial, with 92 female patients undergoing cholecystectomy by laparotomy with conventional or 2 hours shortened fasting. The variables measured were the peak expiratory flow, forced expiratory volume in the first second, forced vital capacity, dominant handgrip strength, and non-dominant handgrip strength. Evaluations were performed 2 hours before induction of anesthesia and 24 hours after the operation. Results: The two groups were similar in preoperative evaluations regarding demographic and clinical characteristics, as well as for all variables. However, postoperatively the group with shortened fasting had higher values than the group with conventional fasting for lung function tests peak expiratory flow (128.7±62.5 versus 115.7±59.9; p=0.040), forced expiratory volume in the first second (1.5±0.6 versus 1.2±0.5; p=0.040), forced vital capacity (2.3±1.1 versus 1.8±0.9; p=0.021), and for muscle function tests dominant handgrip strength (24.9±6.8 versus 18.4±7.7; p=0.001) and non-dominant handgrip strength (22.9±6.3 versus 17.0±7.8; p=0.0002). In the intragroup evaluation, there was a decrease in preoperative compared with postoperative values, except for dominant handgrip strength (25.2±6.7 versus 24.9±6.8; p=0.692), in the shortened fasting group. Conclusion: Abbreviation of preoperative fasting time with ingestion of maltodextrin solution is beneficial to pulmonary function and preserves dominant handgrip strength.

Expiratory Flow

Spirometry and Peak Expiratory Flow Rate (PEFR) are important measurements in diagnosing and monitoring of COPD and asthma. Ethnic specific reference equations are necessary in interpretation of these parameters. However, equations for Sri Lankan Tamil adults are not available. This study aims to establish reference equations for lung function parameters of Sri Lankan Tamils. A descriptive cross sectional study was carried out in all 5 districts of Northern Sri Lanka. Participants were selected by cluster sampling. Base line data were obtained by a questionnaire. Height, sitting height, weight, arm span, mid arm circumference, and chest expansion were measured. Respiratory functions were assessed by a calibrated spirometer (Cosmed Micro Quark, Italy) and Wright compatible peak expiratory flow meter. Means, and standard deviations for Vital Capacity (VC), Forced Vital Capacity (FVC), Forced Expiratory Volume in the first second (FEV1), FEV1%, Peak Expiratory Flow Rate (PEFR) and for other forced expiratory parameters of 775 males and 687 females were determined. Lung function parameters have significant p<0.05 positive correlations with most of the anthropometric measures. Age had a significant p<0.05 negative correlation with lung function parameters in adults >20 years and positive correlation p<0.05 in 14–20 years group. Step wise multiple regression analysis was used to determine the prediction equations. Also equations based on age, height and age, arm span were derived. Age, height based equations were retested in the same population. Predicted values by the developed equations had better agreement than that of GLI 2012 equations. This can be useful in assessing the respiratory function in Sri Lankan Tamil population as there are no already existing equations.

Abstract Background: Lung function test is a useful indicator that measures the presence of mild abnormalities, if any. The present study aimed to compare the lung function in people from different occupations and to correlate with anthropometric measurements and blood pressure. Methods: This cross-sectional study was conducted among students, faculty, gardeners, housekeeping, and support staff of Melaka Manipal Medical College (MMMC) and auto drivers of Manipal. Peak expiratory flow rate (PEFR) and vital capacity (VC) were recorded using a digital spirometer. Breath-holding time (BHT), and blood pressure (BP) were recorded. Waist-to-hip ratio (WHR) and body mass index (BMI) were measured. The data were analyzed using the Prism statistical package. Results: Forty-one males and Thirty-two females participated in this study. PEFR did not significantly differ among the different occupations but was negatively correlated with WHR in females. For VC, male students showed a significantly higher value than gardeners, whereas female students and faculty members had a considerably higher value than housekeepers. VC negatively correlated with age in males. In females, it showed a negative correlation with age, WHR, duration of indoor non-AC exposure, and systolic BP. BHT of male students and staff was significantly higher than auto drivers, and it showed a negative correlation with age, duration of outdoor exposure, and systolic BP. Lung function parameters did not correlate with indoor AC exposure in males and females. Systolic BP was significantly higher in auto drivers than students, and it increased with age in males. In females, systolic BP negatively correlated with outdoor exposure and positively correlated with indoor non-AC exposure. Among females, WHR was significantly higher in housekeepers and staff than students and faculty. Conclusion: The study results showed that vital capacity was lowest among male gardeners and female housekeepers who tend to have occupational exposure to chemicals. Peak expiratory flow rate (PEFR) and vital capacity were lower in females with a tendency towards abdominal obesity. More considerable time spent indoors was associated with lower vital capacity and higher systolic blood pressure in females.

Agreement Study

Objective: To determine the agreement between devices and repeatability within devices of the forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), peak expiratory flow (PEF) and forced expiratory flow at 50% of FVC (FEF50) values measured using the four spirometers included in the study. Methods: 50 (24 women) participants (20-64 years of age) completed maximum forced expiratory flow manoeuvres and measurements were performed using the following devices: MasterScreen, SensorMedics, Oxycon Pro and SpiroUSB. The order of the instruments tested was randomized and blinded for both the participants and the technicians. Re-testing was conducted on a following day within 72 hours at the same time of the day. Results: The devices which obtained the most comparable values for all lung function variables were SensorMedics and Oxycon Pro, and MasterScreen and SpiroUSB. For FEV1, mean difference was 0.04 L (95% confidence interval; -0.05, 0.14) and 0.00 L (-0.06, 0.06), respectively. When using the criterion of FVC and FEV1 ≤ 0.150 L for acceptable repeatability, 67% of the comparisons of the measured lung function values obtained by the four devices were acceptable. Overall, Oxycon Pro obtained most frequently values of the lung function variables with highest precision as indicated by the coefficients of repeatability (CR), followed by MasterScreen, SensorMedics and SpiroUSB (e.g. min-max CR for FEV1; 0.27-0.46). Conclusion: The present study confirms that measurements obtained by the same device at different times can be compared; however, measured lung function values may differ depending on spirometers used.

In Reply.— We thank Drs McJunkin and Stallo for their interest in our paper. Their suggestion of using objective lung function measurements in young children and infants with acute asthma in the emergency department is impractical. The pulmonary index score we used includes at least one important lung function measure, namely, respiratory rate; this score also has been shown to be very reliable in children.1 Although we routinely use the peak expiratory flow rate in children in the emergency department, most of our patients were younger than 3 years of age and could not cooperate with this objective measurement.
