Summary

Due to the concerns of virus transmission during COVID-19 pandemic, multiple respiratory societies postpone or limit pulmonary function test, especially cardiopulmonary exercise test (CPET), as patients may generate large amount of aerosol particles during test but it is conventionally performed without filter. This study aims to investigate the effects of reducing aerosol particle concentrations in the room air during CPET by placing an inline filter, and to assess the effects of filter on the physiologic responses during CPET.

Conditions

  • Transmission, Patient-Professional

Interventions

DEVICE

Respiratory filter in-line placed with the standard mouthpiece

The respiratory filter is a device that removes solid/large particles from gas

OTHER

Standard mouthpiece

The mouthpiece is the interface that is placed on participant's face in order to measure all the breathing physilogic responses
