Exhaled 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...
متن کاملDecrements Encountered when Wearing Hazardous Materials Gloves
Hazardous materials gloves (HAZMAT) are frequently worn when performing clinical technical skills, but it is unclear how sensory and motor performance is affected in these circumstances. In Experiment 1, two timed standardized manual dexterity tests, and a test of sensory function were administered. Glove use resulted in a decreased ability to manipulate small objects and a decreased sensitivit...
متن کاملGait dynamics when wearing a treadmill safety harness.
Nonlinear dynamics quantifies gait variability patterns, which can be useful in evaluating functional ability. A commonly used nonlinear technique is detrended fluctuation analysis (DFA). Safety support structures have previously been shown to alter DFA during gait. However, the effect of a nonweight-supporting treadmill harness on DFA during gait has yet to be determined. The purpose of this s...
متن کاملHelmet Wearing
Humans adapt their risk-taking behaviour based on perceptions of safety; this risk compensation phenomenon is typified by people taking more risks when using protective equipment. Existing studies have looked at people who know they are using safety equipment, and have specifically examined changes in behaviours against which that equipment might reduce risk. We demonstrate risk-taking increase...
متن کاملWearing a telephone
This was an initial exploration of the usefulness and usability of wearable telephony. For more than three months, the author “wore” a suite of devices that included a no-ring, auto-answer cellular phone and a separate WWW-enabled controller. Calls and email were announced verbally and privately in the author’s earpiece. Calls were placed from the controller via a click-to-dial addressbook. The...
