Abstract: A cannula configured to provide positive expiratory pressure (PEP) and oxygen to a patient, including: a base including an oxygen opening and an inhalation opening; a valve including an inhalation flap valve that closes the inhalation opening and a PEP flap valve; a valve retainer including a flow opening and an exhalation opening, wherein the PEP flap valve closes the exhalation opening; and a nasal pillow seated on the valve retainer.

Abstract: A method for controlling a ventilator to provide variable volume (VV) with average volume assured pressure support (AVAPS), including: producing a VV target volume using a VV distribution function; producing a volume error Verror that is the difference between the VV target volume and a measured volume of the previous breath; scaling the volume error Verror; producing a VV target difference as the difference between VV target volume and the VV target volume of the previous breath; producing a modified volume error by adding the VV target difference to the scaled volume error Verror; producing a delta pressure support ΔPS based upon the modified volume error and a dynamic compliance; and producing a current pressure support value based upon the delta pressure support ΔPS and the pressure support value of the previous breath.
