This proposed study will evaluate whether a novel nonpharmacological intervention, Breathing Room, can improve lung function in the target population of older adults. Therefore, the primary aim of this pilot is to examine the effect of Breathing Room on inspiratory muscle strength, spirometry confirmed ventilatory function (Forced Expiratory Volume in one second (FEV1), Forced Vital Capacity (FVC) and FEV1/FVC), functional status, posture, physical activity, and lower respiratory infection rates.
Objective: To determine the effect of breathing exercises on certain physiological parameters, sleep quality and vitality in the elderly. Method: In this randomized controlled, experimental study, pre and post tests were applied to 26 elderly participants in the intervention group and to 25 elderly patients in the control group. The intervention group underwent breathing exercises for 30 minutes at the same time of the day, three days a week for three months (pursed-lip breathing exercise, deep breathing exercise, coughing exercise), while no such exercise was carried out by the control group. Pittsburg Sleep Quality Index, the Subjective Vitality Scale, spirometer, sphygmomanometer and pulse oximetry device measurements were used for the collection of data. The data was evaluated with an independent sample t-test, a paired-sample t-test and a two-way repeated measures ANOVA.
Soccer requires the activation of aerobic and anaerobic metabolism. The increase of the ventilatory demand stimulates the increase of the neural impulse to the respiratory muscles, increasing the mechanical power of the inspiratory muscles. The main objective of the study is to assess the effectiveness in the improvement of the strength of the inspiratory muscles and the muscular recovery with the Powerbreathe® device in semi-professional soccer players. Randomized double-blind clinical study with follow-up period. 36 semi-professional soccer players from the province of Soria will be randomly distributed to the study groups: experimental (inspiratory muscle training with 50% resistance) and control (10% resistance training). The dependent variables will be: aerobic and anaerobic sports performance (Cooper's 12-Minute Run Test and Repeated Sprint Ability), blood lactate concentration (Lactate Scout®), and lung function using the ergo-respiratory parameters (maximum inspiratory pressure, expiratory pressure maximum, forced vital capacity and forced expiratory volume in 1 second). The sample distribution will be calculated using the Kolmogorov-Smirnov test. The changes after each evaluation will be analyzed with the t-student test and with an ANOVA of repeated measures, the intra and intersubject effect will be observed. The effect size will be calculated using Cohen's formula. It is intended to observe improvement in inspiratory strength levels, decrease in blood lactate concentration and an increase in aerobic and anaerobic sports performance.
Volume expansion (VE) is often administered in intensive care (ICU)-patient to improve arterial oxygen delivery. Such effect is secondary to an increase in stroke volume and cardiac output. However, cardiac output increase in response to VE (fluid responsiveness) only occurs when the heart is preload-dependant. Increasing evidence of the deleterious effects of inappropriate fluid administration encourages the development of variables predicting fluid responsiveness, but few have been validated in spontaneously breathing patients. Central venous pressure (CVP) variation in spontaneously patients during standardized or unstandardized inspiratory maneuver may represent an easy tool to predict fluid responsiveness. The hypothesise is that inspiratory maneuver may increase CVP variation in fluid responsiveness patient whereas no or few variation may reflect fluid unresponsiveness.
The primary purpose of this study is to determine if there is a significant difference in regional distribution of ventilation when comparing eupneic tidal ventilation with Incentive Spirometry (I.S.) and EzPAP® lung expansion therapy in healthy adult human subjects. Electrical impedance tomography (EIT) will be used to measure regional distribution of ventilation during resting tidal ventilation and during lung expansion therapy.
Mind-body practices, such as yoga, ta'i chi, mindfulness and biofeedback, commonly use slow breathing techniques to induce physiological and mental relaxation. Medical research suggests that slow breathing techniques induce physiological relaxation. This 6 week study will compare the effects of different types of breathing. The hypothesis is that different breathing techniques produce different physiological and mental changes.
