Product Information

Use of High-Flow Nasal Therapy on Patients with Suspected or Confirmed COVID-19 COVID-19 is a highly contagious disease, and virtually all forms of respiratory support, including high-flow nasal therapy, pose some risk of disease transmission. The U.S. Food and Drug Administration has stated that ventilating patients with communicable diseases using noninvasive devices without a filtered seal from atmosphere may contaminate room air and increase risk of transmission, and that this risk may be exacerbated by high-flow nasal therapy systems. Some clinicians have also suggested that the use of high flow nasal therapy may facilitate the spread of COVID-19 or other communicable diseases through aerosolization of pathogens. If high-flow nasal therapy is used to treat patients with COVID-19 or other communicable diseases, appropriate precautions should be taken, such as placing a mask over the nose and mouth of suspected and infected patients while on high-flow nasal therapy, isolating patients in negative pressure rooms, and providing caregivers with appropriate personal protective equipment specified for aerosol-generating procedures; however, these precautions cannot guarantee that diseases will not be transmitted to caregivers or others.
