Can Wearing an N95 Mask Cause Cardiopulmonary Overload?

 

In a new study, Chinese researchers conclude that wearing an N95 mask for a prolonged period could affect physiologic and biochemical parameters.

 

The authors report that the effect was primarily initiated by increased respiratory resistance and subsequent decreased blood oxygen and pH, which contributed to sympathoadrenal system activation and epinephrine as well as norepinephrine secretion elevation, and a compensatory increase in heart rate and blood pressure.

Evaluation of Mask-Induced Cardiopulmonary Stress (N95)

 

Results

Thirty randomized participants (mean [SD] age, 26.1 [2.9] years; 15 women [50%]) completed the study. Wearing the N95 mask resulted in reduced respiration rate and oxygen saturation by pulse oximetry (Spo2) within 1 hour, with elevated heart rate (mean change, 3.8 beats/min [95% CI, 2.6-5.1 beats/min]) 2 hours later until mask off at 22:00. During the light-intensity exercise at 11:00, mask-induced cardiopulmonary stress was further increased, as heart rate (mean change, 7.8 beats/min [95% CI, 5.3-10.2 beats/min]) and blood pressure (systolic: mean change, 6.1 mm Hg [95% CI, 0.6-11.5 mm Hg]; diastolic: mean change, 5.0 mm Hg [95% CI, 0.3-9.6 mm Hg]) increased, while respiration rate (mean change, −4.3 breaths/min [95% CI, −6.4 to 2.3 breaths/min]) and Spo2 (mean change, −0.66% [95% CI, −1.0% to 0.3%]) decreased. Energy expenditure (mean change, 0.5 kJ [95% CI, 0.2-0.8] kJ) and fat oxidation (mean change, 0.01 g/min [95% CI, −0.01 to 0.03 g/min]) were elevated at 11:00. After the 14-hour masked intervention, venous blood pH decreased, and calculated arterial pH showed a decreasing trend. Metanephrine and normetanephrine levels were increased. Participants also reported increased overall discomfort with the N95 mask (Figure 2).
