Why MaskIT?

MaskIt, LLC and the Diagnostic Guardian™ family provides another barrier.

Endoscopy is a critical part of the ENT examination which brings the doctor to within 20 inches of the patient. It also stimulates the nose and throat to possibly create an unpredictable and spontaneous cough, sneeze or gag. These events may be rare, but expose everyone and the room to unpredictable infectious load. It is not practical nor fiscally responsible to test every patient for every illness prior to scoping. Asymptomatic false negative Covid patients exist; hence universal precautions are critical and have yet to be fully established.

During ENT exams we increase the risk of exposure to infectious particles purely by examining an unprotected source

What has COVID-19 taught you?

Scopes have been found to create aerosols consistent with speaking and breathing unless the patient has a spontaneous sneeze, cough, gag or cry.

Are you or your staff willing to take this risk?

  1. Be prepared by having reserve PPE
  2. Use universal precautions on ALL sick patients with any head and neck illness
  3. During a novel pandemic use universal precautions on all patients (sick or not)
