Healthcare workers have died, become critically ill, sustained injury/disability from COVID-19. All means must be deployed to protect HCWs.

A core principle of emergency response / hazardous materials management training has always been safety first. This is even taught in every CPR class, never enter an unsafe scene. COVID-19 is no different and I think we have learned some important lessons. If we are entering a room and are unsure of the appropriate PPE/precaution level, safety should always be maximized. Over protect then downgrade as evidence becomes available.



Excellent Sustainable / Long-term Respiratory PPE options:

1. Elastomeric, vented, reusable, respirators

These have been used around the world during epidemics for decades. Much cheaper than PAPRs, one is assigned to each healthcare worker (individual accountability), more comfortable, highly effective. These are particularly well suited for triage, evaluating a large number of patients, managing a cohort unit.

3M Models and Filters

PROS- very comfortable, easily sanitized (there is a 3M white sheet on this), minimal inhalation/exhalation resistance, easy to fit test with no additional equipment, low cost

CONS- speech is muffled by the device, communication is more difficult

2. Powered Air-Purifying Respirator (PAPR)

3M Versaflo 300 PAPR Kit with Hood - DQE


PROS- excellent protection, very comfortable, easily sanitized, no respiratory resistance

Elastomeric respirators and PAPRs can inhibit communication. Consider voice amplifiers / Bluetooth headsets to make communication effortless.
