Let’s start by saying that I am not an expert. But, specific guidance from the CDC for managing these patients is available, but I feel like the dispersal of this information is critical to front line EMS providers.

Viral Filters/Airway Management
Viral Filter on BVM

Filters on Inhalation and Exhalation Port of Ventilator

Filter After Flow-Sensor
Update: Hamilton does not specifically recommend a viral filter between the flow sensor and the patient:
- For passive humidification, use a bacteria HME/HMEF filter between the proximal flow sensor and the patient to protect the airway against contamination. Be aware of changes in anatomical dead space and airway resistance.
- Contamination of the flow sensor tube connectors is avoided due to permanent rinse flow through the flow sensor tubing towards the patient
