We wish to comment on the article "Efficacy of Breathing and Coughing Exercises in the Prevention of Pulmonary Complications After Coronary Artery Surgery" by Stiller et al published in March 1994 Chest.1 This remains an important issue for chest physiotherapy and, if the study's findings can be reproduced, could have widespread implications for cardiac surgical units. We believe, however, that...

This study investigated the impact of deep diaphragmatic breathing (DB) on blood gases, breathing pattern, pulmonary mechanics and dyspnoea in severe hypercapnic chronic obstructive pulmonary disease (COPD) patients recovering from an acute exacerbation. Transcutaneous partial pressure of carbon dioxide (Ptc,CO2) and oxygen (Ptc,O2) and arterial oxygen saturation (Sa,O2), were continuously moni...

BACKGROUND AND OBJECTIVES Due to the increasing number of elderly and an increase in the number of cases of cancer by age, cancer is a common problem in the elderly. For elderly patients with cancer, the disease and its treatment can have long-term negative effects on their quality of life (QoL). The purpose of this study was to evaluate the effect of progressive muscle relaxation, body image a...

OBJECTIVES   To evaluate in a general population, the relationships between dysglycaemia, insulin resistance and metabolic variables, and heart rate, heart rate recovery and heart rate variability. METHODS   Four hundred and forty-seven participants in the Data from an Epidemiological Study on the Insulin Resistance syndrome (DESIR) study were classified according to glycaemic status over the...

introduction: pulmonary hyperinflation in patients with chronic obstructive pulmonary disease (copd) can increase the breathing rate and reduce diaphragmatic movements by pushing the diaphragms downward and limiting their movements; this, in fact, can affect the breathing process. the purpose of this study was to compare diaphragmatic movements in copd patients and healthy ones and to evaluate ...

Case summary A 10-year-old neutered male domestic shorthair cat was evaluated because of signs of stertorous breathing and reverse sneezing of 8 months' duration. A CT scan performed 1 week before evaluation indicated nasopharyngeal stenosis or collapse. Increased respiratory effort, stertorous breathing, coughing, reverse sneezing, bilateral black ocular discharge and mucoid left nasal dischar...

This study aims to assess regional ventilation, nonlinearity, and hysteresis of human lungs during dynamic breathing via image registration of four-dimensional computed tomography (4D-CT) scans. Six healthy adult humans were studied by spiral multidetector-row CT during controlled tidal breathing as well as during total lung capacity and functional residual capacity breath holds. Static images ...

The venous blood flow during stretching and deep breathing in the sitting posture was examined in the present study. First, an inguinocrural venous blood flow was measured using the Doppler method. It was confirmed that the blood flow velocity significantly increased during stretching with deep breathing. Second, the peripheral blood circulation in the lower limbs was evaluated during a 60 min ...

Studies show that yogic type of breathing exercises reduces the spontaneous respiratory rate. However, there are no conclusive studies on the effects of breathing exercise on heart rate variability. We investigated the effects of non-yogic breathing exercise on respiratory rate and heart rate variability. Healthy subjects (21-33 years, both genders) were randomized into the intervention group (...
