Brief Summary

People with COPD have more air in their lungs than other people (this problem with high lung volumes is called "hyperinflation"). Unfortunately this is unhelpful as breathing at higher lung volumes requires more effort and contributes to breathlessness. When anyone exercises, they breathe more quickly. People with COPD have narrowed airways, which makes breathing out difficult. When they breathe more quickly they may not be able to breathe out fully before they need to take the next breath in. This means that the volume of air in their lungs tends to increase further during exercise, which makes breathing even more difficult. This problem is called "dynamic hyperinflation". Pulmonary rehabilitation is one of the most helpful interventions for people with COPD and most of the benefit gained is from exercise. Anything that helps people increase the amount of exercise they can perform should lead to further improvements. Non-invasive positive pressure ventilation is a method of supporting a person's normal breathing. The ventilator delivers a flow of air at low pressure as you breathe out, which helps patients to breathe out more completely. The device also detects when patients start to breathe in and delivers a stronger flow of air at a higher pressure, helping them to take a deeper breath in. Previous research studies have shown that when people with COPD use non-invasive ventilation during exercise they are able to exercise for longer and are less breathless. The purpose of this study is to assess whether a new portable non-invasive ventilation device, called the VitaBreath, helps people with COPD recover from breathlessness during the exercise breaks more quickly (by reducing "dynamic hyperinflation", described above) and to exercise for longer overall. The VitaBreath device is small and light, weighing 0.5 kilograms (just over one pound). It is handheld and battery powered.

Outcome Measures

Primary Outcomes (1)

  • Exercise tolerance (total exercise time)

    The primary outcome is exercise tolerance (total exercise time) during continuous and interval exercise.

    12 months

Secondary Outcomes (2)

  • Symptoms

    12 months

  • Dynamic hyperinflation

    12 months

Study Arms (2)

Continuous exercise

EXPERIMENTAL

Patients will undergo a constant load exercise protocol with gas exchange analysis on a cycle ergometer. The exercise protocol will be consisted of repeated 6-min exercise bouts, separated by 2-min rest periods in between work bouts in order to allow application of the VitaBreath device. During the 1st min of each resting period participants will breathe either via the VitaBreath device or normally adopting the pursed lip breathing technique. During the 2nd min of each resting period participants will breathe normally and perform an IC maneuver to assess the magnitude of dynamic hyperinflation.

Device: VitaBreathOther: Pursed Lip Breathing technique

Interval exercise

EXPERIMENTAL

Patients will undergo an interval exercise protocol with gas exchange analysis on a cycle ergometer. The exercise protocol will consist of repeated 2-min exercise bouts, separated by 2-min resting periods in between work bouts in order to allow application of the VitaBreath device. During the 1st min of each resting period participants will breathe either via the VitaBreath device or normally adopting the pursed lip breathing technique. During the 2nd min of each rest period participants will breathe normally and perform an IC maneuver, to assess the magnitude of dynamic hyperinflation.

Device: VitaBreathOther: Pursed Lip Breathing technique

Interventions

The VitaBreath devise will be applied during the 1st minute of each resting period between exercise bouts and during the 1st minute of recovery.

Continuous exerciseInterval exercise

Pursed Lip Breathing technique will be applied during the 1st minute of each resting period between exercise bouts and during the 1st minute of recovery.
