متن کاملExhaled Air Dispersion during Coughing with and without Wearing a Surgical or N95 Mask
OBJECTIVES We compared the expelled air dispersion distances during coughing from a human patient simulator (HPS) lying at 45° with and without wearing a surgical mask or N95 mask in a negative pressure isolation room. METHODS Airflow was marked with intrapulmonary smoke. Coughing bouts were generated by short bursts of oxygen flow at 650, 320, and 220L/min to simulate normal, mild and poor c...
