1. Forced expiratory volume in ml (FEV1·0) and forced vital capacity (FVC) were measured in a random sample of older people (215 men, 272 women) aged 62 years and upwards. 2. Multiple regression equations were calculated to predict these variables by using age and height. In contrast with younger groups most of the variance was not explained by these equations. 3. The equations developed predict lower values for FEV1·0 and FVC than other published series most of which contain relatively few older people.

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.

During coronary angiography in 24 chronic smokers with coronary heart disease, cardiac function measurements were taken and correlated with respiratory function tests. Fourteen patients had evidence of chronic obstructive pulmonary disease. Cardiac output had a direct correlation with vital capacity, forced vital capacity [FVC], forced expiratory volume in 1 s [FEV1], and velocity at 25% of FVC [V [max] 25]. Pulmonary artery resistance was inversely correlated with FEV1/FVC, while pulmonary artery oxygen saturation weakly correlated with FEV1 and V [max] 25. The pulmonary artery pressure had a weak correlation with the pulmonary artery resistance and an intermediate correlation with the right atrium and the right ventricular pressures. Early diagnosis and therapy of chronic obstructive pulmonary disease in smokers may be possible without using invasive methods

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.

This study aimed to compare the effects of cervical stabilization exercises with breathing exercises and cervical stabilization exercises with thoracic spine extension exercises on respiratory function in subjects with forward head posture (FHP). The study included 30 adults with FHP. They were divided into two groups—experimental (EG) and control (CG)—with 15 participants in each group. The EG was asked to perform cervical stabilization exercises with breathing exercises, and the CG was asked to perform cervical stabilization exercises with thoracic spine extension exercises. After 4 weeks of exercise, the changes in respiratory function were measured again. The results showed significant differences in the EG before and after exercise in terms of forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), peak expiratory flow (PEF), and forced vital capacity/vital capacity max (FVC/VCmax%) (p < 0.05). The CG showed only a significant increase in FVC, FEV1, and FVC/VCmax% after the experiment (p < 0.05). In the between-group comparison, there were significant differences noted in FVC, FEV1, PEF, and FVC/VCmax% in the EG compared to the CG (p < 0.05). As a result, cervical stabilization exercises with breathing exercises are recommended to promote respiratory function.

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.

Global Health Issue

Research background. Bronchial asthma is becoming a global health issue: it is an increasingly common illness diagnosed in very young children. It is believed that the majority of people develop this disease in the early childhood. Tai Chi, which is a Chinese martial art combining harmonious breathing and body movements, can help to reduce stress, relax and maintain body balance. In addition, it allows those with asthma to better control their asthmatic fts and to improve physical potential. Research aim was to assess the effect of Tai Chi exercises on the respiratory function of 8–11-year-old children with bronchial asthma. Methods. The research was performed at Public Sanatorium. Two groups, each consisting of 25 children aged 8–11 years suffering from bronchial asthma, underwent examination. The following spirometry indicators were measured and compared: peak expiratory flow (PEF), forced vital capacity (FVC), forced expiratory volume in one second (FEV1), forced expiratory volume in one second to forced vital capacity (FEV1/FVC). Schtange and Genchi specimen indicators were evaluated before and after 4 weeks intervention. The study group practiced Tai Chi exercises and the control group received regular physiotherapy in a gym. Results. All indicators of functional capacity of respiratory function after intervention increased in both groups statistically signifcantly, but there were no signifcant differences between groups. Conclusion. Both regular physiotherapy and Tai Chi exercises were equally effective in improving the respiratory function in children with asthma.Keywords: children, bronchial asthma, Tai Chi, physiotherapy
