Outcome Measures

Primary Outcomes (1)

  • Gas trapping (expressed as percent total lung volume)

    30 minutes

Secondary Outcomes (2)

  • Regional lung ventilation distribution

    30 minutes

  • Coefficient of variation of regional lung ventilation

    30 minutes

Study Arms (1)

Computed tomography examination

EXPERIMENTAL

Each patient will undergo a low-dose supine position chest CT scan including end-inspiratory and expiratory acquisitions, corresponding to the routine protocol for COPD patients, except that this end-inspiratory/end-expiratory CT is repeated 3 times for total of 6 CT acquisitions.

Radiation: Computed tomography

Interventions

End-inspiratory/end-expiratory CT is repeated 3 times corresponding to the 3 studied conditions: At baseline, through expiratory resistive loading using an adjustable PEP mask, and after 5 min of nasal high flow therapy at 25 L/min.

Also known as: CT
Computed tomography examination
