Primary Outcome Measures:
  • EEG change, ABG change, change in scores of attention test, etc

Secondary Outcome Measures:
  • symptoms wearing N95 masks

Estimated Enrollment: 20
Study Start Date: August 2003
Estimated Study Completion Date: June 2005
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.
