Apparatus and method for improved assisted ventilation
Devices and methods for allowing for improved assisted ventilation of a patient. The methods and devices provide a number of benefits over conventional approaches for assisted ventilation. Methods and devices that permit blind insertion of a device that can allow ventilation regardless of whether the device is positioned within a trachea or an esophagus.
1. A method for ventilating an individual, the method comprising:
inserting a ventilation device within a natural respiratory opening of the individual by advancing a working end of the ventilation device within a body passageway of the individual, where the working end includes a distal opening fluidly coupled to a first lumen and a medial opening fluidly coupled to a second lumen;
drawing suction through the distal opening and maintaining the suction for a period of time;
determining whether tissue of the body passageway is drawn against the distal opening by the suction;
ventilating the individual through the first lumen after failing to determine that the tissue of the body passageway is drawn against the distal opening; and
ventilating the individual through the second lumen after determining that the tissue of the body passageway is drawn against the distal opening and maintaining the suction while ventilating through the second lumen.
2. The method of claim 1 , further comprising adjusting a ventilation parameter to improve ventilation of the individual where the ventilation parameter comprises a parameter selected from the group consisting of a ventilation rate, volume, pressure; inhale and exhale ratios, and PEEP.
3. The method of claim 1 , further comprising providing an indicator signal to identify desired times of chest compression.
4. The method of claim 1 , further comprising initially ventilating through the second lumen during application of suction through the first lumen.
5. The method of claim 1 , further comprising deploying an anchor to temporarily secure the ventilation device in the body passageway.
6. The method of claim 5 , where the anchor comprises a balloon coupled to the working end of the ventilation device.
7. The method of claim 1 , where a proximal portion of the ventilation device further comprises a face mask and where the method includes affixing the face mask to the individual.
8. The method of claim 1 , where a proximal portion of the ventilation device further comprises a reinforced section to prevent collapse of the ventilation device in a mouth of the individual.
9. The method of claim 1 , where a proximal portion of the ventilation device further comprises a pressure relief valve to adjust ventilation parameters of the individual.
10. The method of claim 1 , where the ventilation device comprises a plurality of markings on an exterior surface and where inserting the ventilation device into the natural respiratory opening comprises advancing the ventilation device to a depth determined by one or more markings.
11. The method of claim further comprising coupling a collection member to the first lumen and collecting bodily fluids in the collection member during suctioning.
12. The method of claim 1 , where the body passageway comprises either a trachea or an esophagus of the individual.
13. A method for rapidly ventilating an individual experiencing respiratory distress, the method comprising:
inserting a ventilation device within a natural respiratory opening of the individual by advancing a working end of the ventilation device within a body passageway of the individual, where the working end includes a distal opening fluidly coupled to a first lumen and a medial opening fluidly coupled to a second lumen;
pulling a suction force through the distal opening and maintaining the suction force for a period of time;
ventilating the individual through the first lumen when tissue from the body passageway does not seal the distal opening; and
ventilating the individual through the second lumen while maintaining the suction force through the distal opening when the tissue from the body passageway seals the distal opening.
14. The method of claim 13 , further comprising initially ventilating through the second lumen during application of suction through the first lumen.
15. The method of claim 13 , further comprising deploying an anchor to temporarily secure the ventilation device in the body passageway.
16. The method of claim 15 , where the anchor comprises a balloon coupled to the working end of the ventilation device.
17. The method of claim 13 where a proximal portion of the ventilation device further comprises a reinforced section to prevent collapse of the ventilation device in a mouth of the individual.
18. The method of claim 13 , where a proximal portion of the ventilation device further comprises a pressure relief valve to adjust ventilation parameters of the individual.
19. The method of claim 13 , where the ventilation device comprises a plurality of markings on an exterior surface and where inserting the ventilation device into the natural respiratory opening comprises advancing the ventilation device to a depth determined by one or more markings.
20. The method of claim 13 , further comprising coupling a collection member to the first lumen and collecting, bodily fluids in the collection member during suctioning.
21. The method of claim 13 , where the body passageway comprises either a trachea or an esophagus of the individual.
22. A device for ventilating an individual through one or more body passageways using a suction source and a gas supply, the device comprising:
a tubular member having at least a first and second lumen, where the first lumen is fluidly coupled to a first opening located towards a distal portion of the tubular member, the second lumen fluidly coupled to a medial opening being located proximally to the first opening along a wall of the tubular member, where the first opening and medial opening are fluidly isolated within the tubular member;
a control system having a valve configured to fluidly direct the gas supply through either the first lumen or the second lumen;
the control system is configured to direct suction from the suction source through the first opening and first lumen and identify a formation of a seal at the first opening resulting from the suction;
where the control system is configured to ventilate the individual through the first lumen when the seal at the first opening is not identified and ventilate the individual through the second lumen while maintaining suction through the first opening when the seal at the first opening is identified.
23. The device of claim 22 , further comprising an indicator to signal desired times of chest compression.
24. The device of claim 22 , further comprising an anchor to temporarily secure the tubular member in a body passageway.
25. The device of claim 24 , where the anchor comprises a balloon coupled to the distal end of the tubular member.
26. The device of claim 22 , where the tubular member further comprises a reinforced section to prevent collapse of the ventilation device in a mouth of the individual.
27. The device of claim 22 , where the control system further comprises a pressure relief valve to adjust ventilation parameters of the individual.
28. The device of claim 22 , where the tubular member comprises a plurality of markings on an exterior surface and where the tubular member is configured to be advanced to a depth determined by one or more of the markings.
