Any change in breathing pressure may lead to leaks where the N95 should form a seal against the skin, and any mask barrier fabric or straps may interfere with proper fit of the N95 . Just as you can suck air in through a mask rather easily, so can you exhale air out through it. The observed prolonged Ti and increased RAW suggest a change in pulmonary regulation when using a SM.

There is no carbon dioxide in the mask. Surgical face masks increase airway resistance and heart rate during steady state exercise in healthy volunteers. If you overheat easily in a mask, look for inner and outer layers of tightly woven, lightweight, high-tech fabrics that can help keep you cool. Participants were excluded from the tests if they had orthopedic, metabolic, or cardiorespiratory diseases.

Despite these cardiopulmonary changes, the constant load tests at maximal lactate steady state were completed with exception of one test subject when using masks. The respiratory work were calculated from the peak flow and airway resistance (RAW) and showed significant differences (Co 3.00.7kPa vs. SM 4.61.2kPa, p<0.01, n2p=0.71). Sci. Healthcare workers providing direct care or working within the patient/client/resident zone for individuals where assessment suggests a high-risk of transmission, should use P2/N95 respirators rather than face masks, along with the other PPE required.
