Effect of Face Masks on Pulmonary Function in Patients With COPD

Effect of Face Masks on Pulmonary Function in Patients With COPD

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.

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.
