  Purpose

Objective: To analyze the additional benefits of exercise training application by the non-invasive home mechanical ventilation in patients with stable COPD and hypercapnic respiratory failure. SUBJECT: moderate-severe COPD (FEV1 <60%) in chronic respiratory failure (hypoxemia and hypercapnia PaCO2> 45mmHg). GROUPS: 45 patients included prospectively and randomly into 3 groups of 15: a) training + NIPPV group, b) Group training, c) Group NIPPV. Hypothesis: A training program to the effort associated with treatment with NIPPV significantly increase the effects compared with each treatment. MAIN OBJETIVE: Effects on exercise capacity as measured by the test of endurance cycling and test 6-minute walk (distance). SECONDARY OBJECTIVES: Impact on quality of life and dyspnea, as measured by questionnaire and CRQ, systemic inflammatory response (CRP, IL-8, TNF-α), changes in peripheral muscle strength (1RM test, isometric) and effects score BODE index.

Primary Outcome Measures:
  • exercise capacity [ Time Frame: baseline and end of follow-up period (15 weeks) ] [ Designated as safety issue: No ]
    Our primary objective is to verify the beneficial effect on exercise capacity of an exercise training program combined with treatment of positive pressure ventilation noninvasive against each of them separately, in patients with COPD. The improvement in exercise capacity will be assessed by increased resistance time (submaximal exercise test) and distance (test 6-minute walk)


Secondary Outcome Measures:
  • Peripheral muscle strength [ Time Frame: baseline and end of follow-up period (15 weeks) ] [ Designated as safety issue: No ]

    As secondary objectives, we compare the contributions of the combined treatment of:

    a. Peripheral muscle strength (1RM test, maximal isometric strength by dynamometer) and exchange of gases (ABG)


  • quality of life [ Time Frame: baseline and end of follow-up period (15 weeks) ] [ Designated as safety issue: No ]
    Impact on symptoms and quality of life (RCMH, CRQ)

  • inflammation [ Time Frame: baseline and end of follow-up period (15 weeks) ] [ Designated as safety issue: No ]
    Control of the systemic inflammatory response through: CRP, IL-8 and TNF-α

  • BODE [ Time Frame: baseline and end of follow-up period (15 weeks) ] [ Designated as safety issue: No ]
    BODE index as a sensitive parameter of response to therapeutic intervention in these patients.

Arms Assigned Interventions
Experimental: ventilation
Group program of positive pressure ventilation noninvasive
Procedure: ventilation

positive-pressure breathing bilevel (BiPAP ® Respironics, Inc.) Parameters initially programmed be: IPAP 10 cm H2O, EPAP 4 cmH2O, method ST setting yourself respirations 12 breaths minute. The IPAP was progressively increased to a maximum of 20 cm H2O, depending on patient tolerability, clinical response and arterial oxygen saturation was continuously monitored by pulse oximetry, trying to avoid possible leaks through the mask. It can also supply oxygen through a cannula connected to the mask at a flow rate of 2-4 liters per minute to maintain oxygen saturation at around 85-90%.

Patients aired uninterruptedly during nighttime (minimal between 6-8 hours night).

Other Name: Non invasive positive ventilation
Experimental: exercise training

The training program (trained group) was carried out for 12 weeks and sessions of 40 minutes duration:

d. 20 minutes of bicycle ergometer with an initial charge of about 70% of initial maximal oxygen consumption, increasing the load every two weeks as tolerated.

e. Weightlifting in 2 sets of 6 replicates of 5 simple exercises. These are held at a station multigimnástica (CLASSIC Fitness Center, KETTLER)
