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...

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 (...

OBJECTIVE The present study was conducted to assess the effect of controlled deep breathing on psychomotor and higher mental functions. METHODS 100 normal healthy subjects (52 females and 48 males, age range - 18 to 25 years) participated in the study. Each subject acted as his or her own control. Six weeks course of controlled deep breathing i.e. 5 seconds of maximal inhalation followed by 5...

Isolated inner ear decompression sickness (DCS) is recognized in deep diving involving breathing of helium-oxygen mixtures, particularly when breathing gas is switched to a nitrogen-rich mixture during decompression. The biophysical basis for this selective vulnerability of the inner ear to DCS has not been established. A compartmental model of inert gas kinetics in the human inner ear was cons...

Postoperative physiotherapy has been shown to reduce the incidence of postoperative pulmonary complications after open abdominal surgery. This study aimed to determine if the addition of deep breathing exercises and secretion clearing techniques to a standardised physiotherapist-directed program of early mobilisation improved clinical outcomes in patients undergoing open abdominal surgery. Fift...
