Study Summary

Given the heightened vulnerability of COPD patients to severe illness upon SARS-CoV-2 infection, precautions like mask-wearing are deemed crucial. Yet, mask-wearing can exacerbate breathlessness and discomfort in this demographic. This study aims to assess the effects of wearing a face mask during 6-Minute-Walking-Tests (6-MWT) among COPD patients.

Study Description

In this detailed study, we aim to explore the impact of wearing face masks on COPD patients during 6-Minute-Walking-Tests (6MWT). COPD, commonly observed among smokers and former smokers, poses heightened mortality risks upon SARS-CoV-2 infection. Consequently, face masks are often recommended for preventive measures. However, breathlessness remains a predominant symptom in this patient cohort. Moreover, there is a dearth of data concerning blood oxygenation levels while wearing various types of face masks.

The study will involve COPD patients who will undergo three 6MWTs: one without a mask, one with a simple face mask, and one with a FFP2 mask. Prior to each 6MWT, comprehensive pulmonary function tests including spirometry, body plethysmography, and CO-diffusion capacity measurement will be conducted. Additionally, capillary blood gas analysis will be performed both before the 6MWT and after each test session.
