A fit factor of at least 100 is required for half-mask respirators and a minimum fit factor of 500 for a full facepiece negative-pressure respirator. Despite these cardiopulmonary changes, the constant load tests at maximal lactate steady state were completed with exception of one test subject when using masks. Effects of surgical face masks on cardiopulmonary parameters during steady state exercise, $${\dot{\text{V}}}_{A} = \left( {{\text{V}}_{\text{T}} - {\text{VD}}} \right)*{\text{RR}}$$, $${\text{VD}} = {\text{V}}_{\text{T}} *{\text{FetCO}}_{2} \, - \left( {{\text{FeCO}}_{2} /{\text{FetCO}}_{2} } \right)$$, \({\text{V}}_{E}/{\dot{\text{V}}\text{CO}}_{2}\), https://doi.org/10.1038/s41598-020-78643-1.
