Study Details

Study Description

Brief Summary

Wearing N95 masks may have adverse physical effect on medical staff

Condition or Disease	Intervention/Treatment	Phase
Hypoxemia; Hypercapnia	Device: wearing N95 masks	N/A

Detailed 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.
