- The recommendations for Minimum Personal Protective Equipment (PPE) depend on several factors:
- Procedure-related factors: AGMP (Aerosol Generating Medical Procedure) or non-AGMP
- Patient-related factors: symptomatic or asymptomatic
- COVID-19 test results: COVID positive, negative or unknown
- Asymptomatic patients undergoing AGMP should be screened for COVID-19 before the procedure, since the PAPR [Powered Air-Purifying Respirator] is required in COVID-19 positive cases.
- The flowchart guiding the decision-making process in minimum PPE can be summarized in the decision-tree available in this link: https://www.entcanada.org/wp-content/uploads/Protocol-for-COVID-and-AGMP-3-iw-mailer.pdf
- Surgical procedures known to be AGMP include airway procedures, intra-nasal and sinus surgery, head and neck mucosal surgery and mastoid surgery.
These statements come from the guideline published by the Canadian Society of Otolaryngology – Head & Neck Surgery (CSO-HNS) Executive Committee. The recommendations are also based on the BC Centre for Disease Control. Below is the description of each PPE level:
