Abstract:
Patients with COVID-19 often need therapeutic interventions that are considered high aerosol-generating procedures. These are either being performed by healthcare providers with potentially inadequate personal protective equipment or the procedures are being delayed until patients clear their viral load. Both scenarios are suboptimal. We present a simple, cost-effective method of creating a portable negative pressure environment using equipment that is found in most hospitals to better protect healthcare providers and to facilitate more timely care for patients with COVID-19.
