Effects of oxygen breathing on inspiratory muscle fatigue during resistive load in cycling men.
The aim of the present study was to determine the development of the inspiratory muscle fatigue in healthy human during incremental cycling to exhaustion under mild and heavy resistive loaded breathing in air and oxygen. Minute ventilation, tidal volume, respiratory rate, inspiratory mouth pressure, and parasternal EMG activities were recorded during an incremental cycling test under mild (12 c...
متن کاملTask failure with lack of diaphragm fatigue during inspiratory resistive loading in human subjects.
Task failure during inspiratory resistive loading is thought to be accompanied by substantial peripheral fatigue of the inspiratory muscles. Six healthy subjects performed eight resistive breathing trials with loads of 35, 50, 75 and 90% of maximal inspiratory pressure (MIP) with and without supplemental oxygen. MIP measured before, after, and at every minute during the trial increased slightly...
متن کاملChest wall volumes during inspiratory loaded breathing in COPD patients
Chest wall volumes and breathing patterns of 13 male COPD patients were evaluated at rest and during inspiratory loaded breathing (ILB). The sternocleidomastoid (SMM) and abdominal muscle activity was also evaluated. The main compartment responsible for the tidal volume at rest and during ILB was the abdomen. During ILB patients exhibited, in addition to increases in the ratio of inspiratory ti...
متن کاملChest wall regional volume in heart failure patients during inspiratory loaded breathing
Were evaluated individuals divided into two groups: we studied chronic heart failure (CHF) (19 patients with CHF plus cardiomegaly) and control (12 healthy volunteers) during performance of inspiratory loaded breathing (ILB). We evaluated: spirometry, functional capacity through the six-minute walk test (6MWT), and distribution of thoracoabdominal volumes via optoelectronic plethysmography (OEP...
متن کاملInspiratory muscle training increases inspiratory muscle strength in patients weaning from mechanical ventilation: a systematic review.
QUESTION Does inspiratory muscle training improve inspiratory muscle strength and endurance, facilitate weaning, improve survival, and reduce the rate of reintubation and tracheostomy in adults receiving mechanical ventilation? DESIGN Systematic review of randomised or quasi-randomised controlled trials. PARTICIPANTS Adults over 16 years of age receiving mechanical ventilation. INTERVENTI...
