Background: Pranayama involves manipulation of the breath, which is a dynamic bridge between body and mind. The aim of the study was to compare cardio respiratory parameters before and after pranayama practice and to correlate the changes in physical endurance with the changes in cardio-respiratory parameters.Methods: A quasi experimental study was conducted among 120 healthy students in the age group 18-25 years. These students were given pranayama practice for 30 minutes a day for 3 days in a week for 12 weeks. The subjects were assessed for various cardio-respiratory parameters like respiratory rate (RR), forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV1/FVC, peak expiratory flow rate (PEFR) , breath holding time (BHT), Heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), hand grip and rate of oxygen uptake per minute (VO2max) before and after pranayama practice. Statistical analysis included descriptive statistics, paired t test and Pearson correlation.Results: There was a significant decrease in RR, HR, SBP and DBP after pranayama practice. BHT, FVC, FEV1, PEFR, hand grip and vo2 max were significantly increased after pranayama practice. Physical endurance is positively correlated with hand grip and heart rate.Conclusions: The results emphasis the health benefits of pranayama. Regular pranayama improves the cardiovascular efficiency and physical endurance. In spite of yogic training being not very vigorous, cardio-respiratory efficiency was found to increase. Pranayama practice can be advocated to improve cardio-respiratory efficiency for patients as well as healthy individuals.

Purpose: Several studies raised the effects of Ramadan fasting on healthy adults spirometric data, but none was performed in children. The aim of this study was to compare the spirometric data of a group of faster adolescents (n = 26) with an age-matched non-faster one (n = 10). Methods: This comparative quasi-experimental study, including 36 healthy males aged 12 to 15 years, was conducted during the summer 2015 (Ramadan: June 18 to July 16). Three sessions (Before-Ramadan [Before-R], Mid-Ramadan [Mid-R], After-Ramadan [After-R]) were selected for spirometry measurements. Spirometry was performed around 5.5 to 3.5 h before sunset and the spirometric data were expressed as percentages of local spirometric norms. Results: The two groups of fasters and non-fasters had similar ages and weights (13.35 ± 0.79 vs 12.96 ± 0.45 years, 46.8 ± 9.2 vs 41.7 ± 12.6 kg, respectively). There was no effect of Ramadan fasting on forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), FEV1/FVC, peak expiratory flow, and maximal mid-expiratory flow. For example, during the Before-R, Mid-R, and After-R sessions, there was no significant difference between the fasters and non-fasters mean FVC (101 ± 11 vs 99 ± 14, 101 ± 12 vs 102 ± 14, 103 ± 11 vs 104 ± 13, respectively) or FEV1 (101 ± 13 vs 96 ± 16, 98 ± 11 vs 97 ± 16, 101 ± 10 vs 98 ± 16, respectively). Conclusions: Ramadan fasting had no interaction effect with the spirometric data of Tunisian healthy male adolescents.

The Impact

<b><i>Background:</i></b> Video-assisted surgical lung biopsy (SLB) is performed in 10–30% of cases to establish the diagnosis of idiopathic pulmonary fibrosis (IPF). <b><i>Objectives:</i></b> The aim of the study was to analyze the impact of SLB on lung function in patients eventually diagnosed with IPF. <b><i>Methods:</i></b> This is an observational, retrospective, monocentric study of all consecutive patients eventually diagnosed with IPF in multidisciplinary discussion who underwent SLB over 10 years in a specialized center. The primary end point was the variation in forced vital capacity (FVC) before and after the SLB. The secondary end points were the variations in forced expiratory volume in one second (FEV1), total lung capacity (TLC), carbon monoxide diffusion capacity (DLCO), and morbidity and mortality associated with the SLB. <b><i>Results:</i></b> In 118 patients who underwent SLB and were diagnosed with IPF, a relative decrease in FVC of 4.8% (<i>p</i> &#x3c; 0.001) was found between measurements performed before and after the procedure. The mean FVC decrease was 156 ± 386 mL in an average period of 185 days, representing an annualized decline of 363 ± 764 mL/year. A significant decrease was also observed after SLB in FEV1, TLC, and DLCO. Complications within 30 days of SLB occurred in 14.4% of patients. Two patients (1.7%) died within 30 days, where one of them had poor lung function. Survival at 1 year was significantly poorer in patients with FVC &#x3c;50% at baseline. <b><i>Conclusion:</i></b> In this uncontrolled study in patients ultimately diagnosed with IPF, SLB was followed by a significant decline in FVC, which appears to be numerically greater than the average decline in the absence of treatment in the literature. <b><i>Summary at a Glance:</i></b> This study evaluated the change in lung function in 118 consecutive patients diagnosed with idiopathic pulmonary fibrosis by surgical lung biopsy. Forced vital capacity decreased by 156 ± 386 mL in a mean of 185 days between the last measurement before and first measurement after biopsy, representing an annualized decline of 363 ± 764 mL/year.

Pulmonary function (PF) is particularly important in synchronized swimming, considering the characteristics of this sport. However, the sanitizing agents (chlorine) used in pools can have a possible negative influence on the PF parameters. In this study, we observed 24 swimmers (all women, 14 to 16 years of age) and measured their PF and competitive achievement. PF was measured before and after a 1-year period and included standard spirometric variables. Competitive achievement was evidenced during the National Championship. The t-test showed significant increases in body height and weight of the participants and a resulting increase in most of the absolute respiratory flows and pulmonary capacities. Forced vital capacity (FVC) and forced expiratory volume (both in proportion to norm for body height, gender, and age) increased significantly within the study period. FVC significantly predicted the competitive achievement of young swimmers, most probably because artists have to achieve exceptional breath control when upside down underwater. In conclusion, we found no evidence for the eventual negative influence of chlorine and its compounds on the PF of swimmers, and results showed that regular synchronized swim training could improve the PF of young artists.

Background: Accurate blood pressure (BP) measurement is a constant challenge, particularly in intensive care units. Thus, studies focusing on avoiding errors in practices of measuring BP are important to patient safety. The objective was to assess the effects of an educational intervention addressing BP measurement, targeting the theoretical and practical knowledge of nurses from a cardiac unit.Methods: This quasi-experimental, before-and-after, study was conducted in a large tertiary hospital in Brazil and included all nurses working in that unit (31 nurses, 86.1%). Data were collected through two types of assessments: practical and theoretical knowledge of the technique, before-and-after the educational intervention that involved simulation as a teaching strategy. A validated checklist was used for both assessments.Results: Most participants were female (64.5%), with an average age of 33.1 years old. Considerable improvement was observed in theoretical and practical knowledge concerning the steps used for BP measurement (p < .05). Considering the total sample, nurses complied with all steps of the BP measurement after educational intervention and the results were considered statistically significant (p < .05).Conclusions: The educational intervention improved the knowledge of nurses, which may contribute to safer healthcare delivery and error-free BP measurements.

BACKGROUND: Bronchodilator responses (BDR) are routinely used in the diagnosis and management of asthma; however, their acceptability and repeatability have not been evaluated using quality control criteria for preschool children.OBJECTIVES: To compare conventional spirometry with an impulse oscillometry system (IOS) in healthy and asthmatic preschool children.METHODS: Data from 30 asthmatic children and 29 controls (two to six years of age) who underwent IOS and spirometry before and after salbutamol administration were analyzed.RESULTS: Stable asthmatic subjects significantly differed versus controls in their spirometry-assessed BDR (forced expiratory volume in 1 s [FEV1], forced vital capacity and forced expiratory flow at 25% to 75% of forced vital capacity) as well as their IOS-assessed BDR (respiratory resistance at 5 Hz [Rrs5], respiratory reactance at 5 Hz and area under the reactance curve). However, comparisons based on the area under the ROC curve for ΔFEV1% initial versus ΔRrs5% initial were 0.82 (95% CI 0.71 to 0.93) and 0.75 (95% CI 0.62 to 0.87), respectively. Moreover, the sensitivity and specificity for ΔFEV1≥9% were 0.53 and 0.93, respectively. Importantly, sensitivity increased to 0.63 when either ΔFEV1≥9% or ΔRrs5≥29% was considered as an additional criterion for the diagnosis of asthma.CONCLUSION: The accuracy of asthma diagnosis in preschool children may be increased by combining spirometry with IOS when measuring BDR.

Abstract The purpose of this study was to examine the effects of training with intermittent breath holding (IBH) on respiratory parameters, arterial oxygen saturation (SpO2) and performance. Twenty-eight fin-swimming athletes were randomly divided into two groups and followed the same training for 16 weeks. About 40% of the distance of each session was performed with self-selected breathing frequency (SBF group) or IBH (IBH group). Performance time of 50 and 400 m at maximum intensity was recorded and forced expired volume in 1 s (FEV1), forced vital capacity (FVC), peak expiratory flow (PEF) and SpO2 were measured before and after the 50 m test at baseline and post-training. Posttraining, the respiratory parameters were increased in the IBH but remained unchanged in the SBF group (FEV1: 17 ±15% vs. -1 ±11%; FVC: 22 ±13% vs. 1 ±10%; PEF: 9 ±14% vs. -4 ±15%; p<0.05). Pre compared to post-training SpO2 was unchanged at baseline and decreased post-training following the 50 m test in both groups (p<0.05). The reduction was higher in the IBH compared to the SBF group (p<0.05). Performance in the 50 and 400 m tests improved in both groups, however, the improvement was greater in the IBH compared to the SBF group in both 50 and 400 m tests (p<0.05). The use of IBH is likely to enhance the load on the respiratory muscles, thus, contributing to improvement of the respiratory parameters. Decreased SpO2 after IBH is likely due to adaptation to hypoventilation. IBH favours performance improvement at 50 and 400 m fin-swimming.

This study was designed to measure changes in blood pressure (BP), urinary catecholamines and ventilatory functions of patients with mild essential hypertension after 10 weeks of Qigong (Shuxinpingxuegong). Fifty-eight patients volunteered to participate in this study and were randomly divided into either a Qigong group (n = 29), or a control group (n = 29). Systolic blood pressure and diastolic blood pressure decreased significantly in the Qigong group such that both became significantly lower after 10 weeks in the Qigong than in the control group. Also, there was a significant reduction of norepinephrine, metanephrine and epinephrine compared to baseline values in the Qigong group. The ventilatory functions, forced vital capacity and forced expiratory volume per sec, were increased in the Qigong group but not the control. These results suggest that Qigong may stabilize the sympathetic nervous system is effective in modulating levels of urinary catecholamines and BP positively, and in improving ventilatory functions in mildly hypertensive middle-aged patients.

The objective is to examine and compare the usability of two physiotherapy programmes, analyzing respiratory function in patients before and after cardiac surgery in hospital during seven postoperative days (POD). Quantitative randomized prospective study of 157 patients before and after the valve replacement surgery, coronary artery bypass graft and combined surgeries, who moved independently. Participants were randomized into two groups (1 and 2) with different physiotherapy programmes. The routine physiotherapy of breath-enhancing techniques, micro-circulation improvement were used for the first group, for the second group - modified physiotherapy – the improvement of inspiration muscles, mm. quadriceps. gluteus max strength. Anthropometric measurements were defined for both groups on the day before surgery and during spirography - dynamic indicators - forced vital capacity (FVC), forced expiratory volume in the 2nd second (FEV1), Tiffeneau index (FEV1 / VC (%)), peak expiratory flow (PEF), operation parameters. By comparing the postoperative respiratory parameters between the two groups and using independent samples t test, it was found out that the difference in FVC between groups is 1.71 [95% CI: −8.25 to 4.8] and it is not statistically significant (t (155) = −0.52; p = 0.60). Based on the Leuven test results FVC the distribution variance is not statistically notably different for group 1 and group 2 (F = 0.27, p=0.60). Using routine and modified physiotherapy and comparing postoperative dynamic respiratory performance of the two groups, there was no statistically significant difference, proving that the two models are equally effective.

AbstractPurpose. The purpose of this study was to evaluate the effect of regular swimming activity on the respiratory system of smokers and non-smokers. Methods. The study included 196 students, aged 19 to 24 years, attending weekly swimming classes. All students underwent pulmonary function testing before and after participating in a swimming program for 10 months. Measurements included forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and peak expiratory flow (PEF). Maximal inspiratory and expiratory pressure at the mouth (PImax, PEmax) and the percentage carboxyhemoglobin level in blood (%CoHb) were also measured. Results. After 10 months of regular swimming activity the values of FVC, PEF, MIP and MEP increased in the non-smoking as well as in the smoking group, while the FEV1 increased only among smokers. The percentage of CoHB level in the blood decreased in both groups. Conclusions. The study confirmed the positive effect of swimming on respiratory system function and the importance of promoting physical activity such as swimming among cigarette smokers as well as non-smokers.
