Introduction. Postoperative ineffective cough is easy to occur after thoracic surgery, and it is also a risk factor for postoperative pulmonary complications (PPCs). Objectives. To explore the value of peak expiratory flow rate (PEF) in evaluating cough ability in patients undergoing lung surgery and evaluate the effectiveness of chest wall compression during the expiratory phase by PEF. Methods. From September 2020 to May 2021, the researchers collected the data of patients who underwent lung surgery. Eventually, 153 patients who met the criteria were included, 102 cases were included in the effective cough group and 51 cases were included in the ineffective cough group. The receiver working curve (ROC curve) was used to analyze whether PEF could evaluate cough ability. At the same time, the researchers collected the pulmonary function data of the first 30 patients of the ineffective cough group while compressing the chest wall during the expiratory phase to evaluate the effectiveness of chest wall compression. Results. The area under the curve (AUC) of postoperative PEF to evaluate the postoperative cough ability was 0.955 (95% CI: 0.927–0.983, P < 0.001 ). The values of PEF (127.17 ± 34.72 L/min vs. 100.70 ± 29.98 L/min, P < 0.001 , 95% CI: 18.34–34.59) and FEV1 (0.72 (0.68–0.97) L vs. 0.64 (0.56–0.82) L, P < 0.001 ) measured while compressing the chest wall were higher than those without compression. Conclusions. PEF can be used as a quantitative indicator of cough ability. Chest wall compression could improve cough ability for patients who have ineffective cough.

Obesity has become one of the major health issues in India. WHO defines obesity as “A condition with excessive fat accumulation in the body to the extent that the health and wellbeing are adversely affected”. Obesity results from a complex interaction of genetic, behavioral, environmental and socioeconomic factors causing an imbalance in energy production and expenditure. Peak expiratory flow rate is the maximum rate of airflow that can be generated during forced expiratory manoeuvre starting from total lung capacity. The simplicity of the method is its main advantage. It is measured by using a standard Wright Peak Flow Meter or mini Wright Meter. The aim of the study is to see the effect of body mass index on Peak Expiratory Flow Rate values in young adults. The place of a study was done tertiary health care centre, in India for the period of 6 months. Study was performed on 80 subjects age group 20 -30 years, categorised as normal weight BMI =18.5 -24.99 kg/m2 and overweight BMI =25-29.99 kg/m2. There were 40 normal weight BMI (Group A) and 40 over weight BMI (Group B). BMI affects PEFR. Increase in BMI decreases PEFR. Early identification of risk individuals prior to the onset of disease is imperative in our developing country. Keywords: BMI, PEFR.

Actuality of Research. Scientific works proved that the greater the volume of the lungs, the better the physical abilities of athletes. So researching of the functional state of organism, namely the level of lung capacity of volleyball players is very important. The aim of the Researching. Determining of the level of lung capacity, forced air volume in 1 second and peak expiratory flow rate in volleyball qualifications. Results. The average rate of lung capacity of volleyball players is – 3,98 l, Forced air volume in 1 second – 3,32 liters, peak expiratory flow rate 5,77 – l/sec. Conclusions. The results of researching indicate that the level of vital capacity in girls is rather higher. So volleyball players (girls) have a high level of fitness of the body, providing adaptation to hight loads and hight endurance.

Background: In Chronic Obstructive Pulmonary Disease (COPD), as result of dynamic hyperinflation, primary respiratory muscles go into weakness and length tension relationship of muscles is altered. This leads to decreased ability of primary respiratory muscles to generate muscle tension. COPD patients mostly use accessory muscle for breathing and there is lack of facilitation of intercostal muscle and weakness of diaphragm. Few studies are conducted to assess the immediate effect of Chest Proprioceptive Neuromuscular Facilitation (PNF) i.e. intercostal stretch among COPD patients. Therefore, there is need to find out immediate effect of chest PNF- intercostal stretch on respiratory rate (RR), chest expansion, peak expiratory flow rate (PEFR) among patient with COPD. Objective: To find out immediate effect chest PNF on respiratory rate, chest expansion and peak expiratory flow rate. Methodology: Ethical clearance and participant consent was taken. Study design was Qausi experimental study. The 65 subjects were taken by convenient sampling. Intercostal stretch was applied over 2nd and 3rd rib bilaterally for 10 breaths with 1 minute rest with a 10 repetitions and Outcome measures were assessed before and immediately after giving chest PNF. SPSS 16 software was used to analyse the data. The normality of the data was assessed using parametric paired t test. Significance level was set at 0.05 and 95% Confidence Interval. Outcome Measures: Respiratory rate, Chest expansion, Peak expiratory flow rate. Result: Immediate effect of chest PNF showed that there was statistically significant increase in PEFR and chest expansion at three level (P=0.000) and there was statistically significant decrease in RR (P=0.000). Conclusion: There is immediate effect of Chest PNF- intercostal stretch on, Respiratory rate, Chest expansion at three level that is axillary, nipple and xiphisternal and Peak expiratory flow rate. It is an easy to use, less time consuming, easy to understand and cost effective technique. KEY WORDS: Chest PNF, intercostal stretch, COPD.
