Abstract: A ventilator, comprising: a manual resuscitator; a motor; a compression plate that is mechanically coupled to the motor, wherein operation of the motor causes the compression plate to periodically compress the manual resuscitator against a resuscitator plate; and one or more operational parameter adjustment controls, wherein operation of the motor is adjusted in response to a value of a particular operational parameter being changed using the one or more operational parameter adjustment controls.

Abstract: A ceiling mounted and extendable tray apparatus is provided, in which a plurality of trays is supported from an overhead housing and operably lowered for access to equipment stored therein. The one or more trays are horizontally supported by an elongated arm that is slidably and pivotably attached to a housing mounted to the ceiling. Each of the trays is supported from the arm via a track along each tray side, while a secondary arm extends between the track and the arm to support the tray in a horizontal condition. Each of the trays is slidable from the elongated arm when lowered, while a slidable cover is disposed over each tray. The trays are aligned in a staggered configuration when deployed, and furthermore in a stacked and condensed state when stowed within the housing. A locking mechanism secures the lowermost tray against the housing to retain the trays therein.
