The Effect of Controlled Breathing Exercises on Anxiety and Arterial Oxygen Saturation in Chronic Obstructive Pulmonary Disease
Introduction: Anxiety is one of the common symptoms and complications in patients with chronic obstructive pulmonary disease that increases readmission and decreases the quality of life in these patients. Objective: This study aimed to determine the effect of controlled breathing exercises on Anxiety and Arterial Oxygen Saturation in chronic obstructive pulmonary disease in the intensive care u...
متن کاملEffects of oxygen breathing on pulmonary vascular input impedance in patients with pulmonary hypertension.
The effect of oxygen breathing on the stiffness of the large pulmonary artery has not been elucidated. We analyzed the proximal pulmonary arterial impedance with a multisensor catheter in ten patients with pulmonary arterial hypertension (PAH), eight patients with pulmonary venous hypertension, and six control subjects. The stiffness of the vessel was quantified by the characteristic impedance ...
متن کاملEffects of breathing 10 per cent carbon dioxide on the pulmonary circulation of human subjects.
SUMMARY The effects on the pulmonary circulation of breathing 10% CO2 for 10 to 20 min were studied in five eucapnic and 11 convalescing hypercapnic patients to recreate the CO2 tensions which they had experienced during respiratory failure. Right heart catheterization permitted measurements of pulmonary arterial and wedge pressures and obtaining samples of mixed venous blood. Breathing CO2 inc...
متن کاملModulation of pulmonary arterial input impedance during transition from inspiration to expiration.
We investigated whether respiration influences pulmonary arterial input impedance during transition from inspiration to expiration in five anesthetized, spontaneously breathing dogs. Impedance (Z) was separately assessed for heart beats occurring in inspiration, in expiration, and during the transition from inspiration to expiration (transitional beat). Transitional beats were scored by the rat...
متن کاملThe Effect of Motivational Abdominal Breathing Device on Breathing Patterns and Shortness of Breath in Patients with Chronic Obstructive Pulmonary Disease
Background and purpose: Despite the high prevalence of chronic obstructive pulmonary disease, There haven,t been definite curative treatment for the disease and focus of treatment has directed towards pulmonary rehabilitation as an effective non-drug treatments. this study were performed to determine the effect of motivational abdominal breathing device on breathing pattern and dyspnea of chron...
