Inspir Labs has developed a solution for the safe use of noninvasive ventilation (NIV) to protect against airborne pathogens. Inspir Labs' solution is based on the creation of a pressure gradient to ensure that no aerosol contamination is introduced into the immediate surroundings, thereby allowing the safe use of NIV methods in any necessary environment. This approach to aerosol safety aims to solve the challenges of attempting to seal a constantly positively pressurized device.
