Bag and valve for advanced respiratory support

A method of providing respiratory support to a patient, the method comprising:

• providing a respiratory device comprising:
• an expandable bag having a first end and a second end, the expandable bag comprising a hinge at the first end configured to reinflate the expandable bag at a predetermined rate and a rigid connection member connected to the first end and adjacent the hinge, and in fluid communication with the expandable bag, the connection member having an inlet connected to the expandable bag, the inlet having a central axis, and an outlet configured to be connected to a patient breathing interface, the outlet having a central axis perpendicular to the central axis of the inlet, and wherein the hinge is configured to open and close along an axis that is parallel to the central axis of the inlet;
• and
• selecting a predetermined tidal volume of the expandable bag;
• selecting a pressure of a positive end-expiratory pressure (PEEP) valve with a PEEP controller;
• and
• having a user compress the expandable bag to provide air to the patient, wherein the user is prevented from compressing the expandable bag beyond the predetermined tidal volume.

A respiratory device for providing respiratory support to a patient, the respiratory device comprising:

• an expandable bag having a first end and a second end, the expandable bag comprising:
• an air intake valve;
• a hinge at the first end, the hinge configured to maintain the expandable bag in a maximum capacity in an uncompressed configuration, and wherein after compression, the hinge is configured to reinflate the expandable bag;
• and
• a rigid connection member connected to the first end of the expandable bag, adjacent the hinge, and in fluid communication with the expandable bag, the connection member having an inlet connected to the expandable bag, the inlet having a central axis, and an outlet configured to be connected to a patient breathing interface, the outlet having a central axis perpendicular to the central axis of the inlet;
• and
• wherein the hinge is configured to open and close along an axis that is parallel to the central axis of the inlet of the connection member.

A respiratory device for providing respiratory support to a patient, the respiratory device comprising:

• an expandable bag comprising an air intake valve and a hinge, the hinge configured to maintain the expandable bag in a maximum capacity in an uncompressed configuration, and wherein after compression the hinge is configured to reinflate the expandable bag;
• a connection member in fluid communication with the expandable bag portion, the connection member comprising:
• a duckbilled valve configured to allow air to move from the expandable bag portion in a first direction and directs air through a positive end expiratory pressure (PEEP) valve in an opposing direction;
• a PEEP controller comprising a dial, wherein turning the dial lifts a lifting piece relative to the duckbilled valve to adjust a distance between the lifting piece and the duckbilled valve;
• and
• wherein the connection member is capable of connecting to a patient breathing interface.
