Effect of Inspiratory Muscle Training on Physiological Function and Clinical Outcomes After Lung Transplant

The purpose of this research is to study the effect of training the inspiratory muscles (i.e. the muscle that allow you to breath-in) on exercise capacity, quality of life, and short-term clinical outcomes in patients post lung transplant.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • All patients who undergo single- or double-lung transplant at Mayo Clinic Florida.

Exclusion criteria

  • Patients undergoing retransplantation.
  • Patients undergoing multiorgan transplantation.
  • Patients who are not willing to or who are unable to give written informed consent.

Treatment and study plan

POWERBreathe Plus®

Device

Commercially available pressure-threshold device

Cardiopulmonary rehabilitation post lung transplant

Other

Pulmonary function, lung diffusing capacity for carbon monoxide, inspiratory muscle strength, and diaphragm dimensions will be assessed in each patient. Each patient will also undergo a cardiopulmonary exercise test (CPET), 6 minute walk test, and an inspiratory muscle endurance test

Primary outcomes

  1. Maximal inspiratory mouth pressure (MIP) measured in cmH2O

    Time frame: 12 weeks

    The maximal strength generating capacity of the inspiratory muscles.

Secondary outcomes

  1. Maximal oxygen uptake (V̇O2max) measured in mL/kg/min

    Time frame: 12 weeks

    Vo2 max is the maximal measured oxygen uptake during a symptom limited exercise test.

Other outcomes

  1. Six-minute walk test distance (6MWTd) measured in meters (m)

    Time frame: 12 weeks

    Distance walked during a 6 minute test

  2. Peak work rate (Wpeak) (watts)

    Time frame: 12 weeks

    The maximal work achieved in watts during a symptom limited exercise test.
