Novel Barrier Enclosure for Both Aerosol and Droplet Protection Model

Area of Science:

• Emergency Medicine
• Infectious Diseases
• Medical Device Safety

Background:

• Emergency physicians face high risks of exposure to infectious respiratory diseases.
• Intubation procedures significantly increase provider exposure risk to droplet and aerosol secretions.
• Intubation boxes are recommended on social media, but evidence of effectiveness is limited.

Purpose of the Study:

• To evaluate the effectiveness of a novel barrier enclosure in reducing provider contamination during intubation.
• To quantify droplet spread during intubation with and without the barrier enclosure.

Main Methods:

• A novel barrier enclosure was tested using a fluorescent simulated respiratory contagion.
• The degree of droplet contamination to the intubator was measured.
• The study modeled droplet spread during intubation procedures.

Main Results:

• The barrier enclosure demonstrated added protection for providers performing intubation.
• A significant reduction in the spread of simulated respiratory droplets was observed when using the device.
• The novel device effectively contained contaminants during the simulated procedure.

Conclusions:

• The tested barrier enclosure provides significant protection against droplet contamination for healthcare providers during intubation.
• This device is a valuable tool for reducing exposure during aerosol-generating procedures in emergency medicine.
• Further research should validate these findings in clinical settings.
