Circulatory effects of expiratory flow-limited exercise, dynamic hyperinflation and expiratory muscle pressure
نویسنده
چکیده
This article reviews recent research in normal subjects exercising with and without expiratory flow limitation at ,1 L?s imposed by a Starling resistor in the expiratory line, and in patients with chronic obstructive pulmonary disease (COPD), using optoelectronic plethysmography to measure respiratory kinematics, combined with mouth, pleural and abdominal pressure measurements, to assess work of breathing and respiratory muscle

Lung hyperinflation in COPD: applying physiology to clinical practice
In chronic obstructive pulmonary disease (COPD), worsening expiratory flow limitation together with alteration in the elastic properties of the lung are associated with progressive lung hyperinflation and gradual decline in the resting inspiratory capacity over time. Dynamic hyperinflation (DH) refers to the variable increase in end-expiratory lung volume (EELV) above the relaxation volume (VR)...
متن کاملHyperinflation, dyspnea, and exercise intolerance in chronic obstructive pulmonary disease.
Expiratory flow limitation is the pathophysiologic hallmark of chronic obstructive pulmonary disease (COPD), but dyspnea (breathlessness) is its most prominent and distressing symptom. Acute dynamic lung hyperinflation, which refers to the temporary increase in operating lung volumes above their resting value, is a key mechanistic consequence of expiratory flow limitation, and has serious mecha...
متن کاملCHRONIC OBSTRUCTIVE PULMONARY DISEASE Regional chest wall volumes during exercise in chronic obstructive pulmonary disease
Background: Dynamic hyperinflation of the lungs impairs exercise performance in chronic obstructive pulmonary disease (COPD). However, it is unclear which patients are affected by dynamic hyperinflation and how the respiratory muscles respond to the change in lung volume. Methods: Using optoelectronic plethysmography, total and regional chest wall volumes were measured non-invasively in 20 stab...
متن کاملEffects of nasal positive expiratory pressure on dynamic hyperinflation and 6-minute walk test in patients with COPD.
INTRODUCTION Dynamic hyperinflation is an important target in the treatment of COPD. There is increasing evidence that positive expiratory pressure (PEP) could reduce dynamic hyperinflation during exercise. PEP application through a nasal mask and a flow resistance device might have the potential to be used during daily physical activities as an auxiliary strategy of ventilatory assistance. The...
متن کامل"Intrinsic" PEEP (PEEPi): role of expiratory muscles.
In normal subjects breathing at rest, lung volume at end-expiration corresponds with the elastic equilibrium volume, or relaxation volume (Vr), of the respiratory system. If expiratory duration is not long enough, then inspiration may begin before the system has returned to Vr, such that end-expiratory lung volume is higher than Vr. This condition is named dynamic pulmonary hyperinflation and "...
