Clinical Trial Summary

Wearing N95 masks may have adverse physical effect on medical staff

Description:

Wearing N95 masks results in hypooxygenemia and hypercapnia which reduce working efficiency and the ability to make correct decision.

Medical staff are at increased risk of getting 'Severe acute respiratory syndrome'(SARS), and wearing N95 masks is highly recommended by experts worldwide. However, dizziness, headache, and short of breath are commonly experienced by the medical staff wearing N95 masks. The ability to make correct decision may be hampered, too. The purpose of the study was therefore to evaluate the physiological impact of N95 mask on medical staff.
