Let’s read an article a month – June 2022

Every month I read an open-access article. I share the title and associated link with my followers to encourage clinicians to read more articles, stay up to date, and continue to grow.

The objective of this month’s paper is “to compare the impact of wearing different masks during a 6MWT on respiratory symptoms, SpO2, and functional capacity” (p86).

Wearing different masks while performing submaximal functional activities results in no difference in oxygen saturation and functional exercise performance. However, wearing cloth masks and N95 masks results in increased dyspnea and breathing effort.


It is important to note that this is a small study of 29 young and healthy subjects who did not have any cardiopulmonary disease or limitations (p86).

Happy reading and learning,
