PAPRs are not effective during firefighting, in an oxygen-deficient atmosphere, or in an unknown atmosphere; in these situations a self-contained breathing apparatus or supplied-air respirator is recommended instead. [5] PAPRs have the advantage of eliminating breathing resistance caused by unpowered negative-pressure respirators such as N95 masks.
An open circuit SCBA typically has three main components: a high-pressure gas storage cylinder, (e.g., 2,216 to 5,500 psi (15,280 to 37,920 kPa), about 150 to 374 atmospheres), a pressure regulator, and a respiratory interface, which may be a mouthpiece, half mask or full-face mask, assembled and mounted on a framed carrying harness.

On March 24, 2020, the U.S. Secretary of Health and Human Services (HHS) enacted Emergency Use Authorizations [53] to allow the use of additional devices, including: "Ventilators, positive pressure breathing devices modified for use as ventilators (collectively referred to as 'ventilators'), ventilator tubing connectors, and ventilator ...

The CDC suggests that, in non-healthcare settings, building ventilation should be brought up to 5 air changes per hour, along with the use of MERV-13 filters, the use of air purifiers (air cleaners), and upper-room Ultraviolet germicidal irradiation (UVGI) to reduce the odds of infection and people coming down with COVID-19.
Non-invasive ventilation (NIV) is the use of breathing support administered through a face mask, nasal mask, or a helmet.Air, usually with added oxygen, is given through the mask under positive pressure; generally the amount of pressure is alternated depending on whether someone is breathing in or out.
