Abstract: Described herein are improved assisted ventilation interfaces along with methods and uses thereof. The interfaces comprises a hood embodiment with altered design aspects to decrease or even avoid the risk of leakage and potential viral transmittance along with providing other benefits. In one aspect, the patient interface comprises a hood with a free-breathing valve and an integral viral filter. The free-breathing valve and viral filter may be separate to or integral to the exhaust port. In a further embodiment multiple branches may be used from the exhaust port with multiple viral filters. In a further embodiment, an internal pressure gauge may be used. In a further embodiment dual air sources may be used.
