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. For example, the methods and devices described herein 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:
advancing a working end of a ventilation device within a body passageway of the individual, where the working end includes a distal opening and a medial opening proximally spaced from the distal opening;
drawing suction through the distal opening and maintaining the suction for a period of time while monitoring a fluid parameter to indicate movement of the wall of the body passageway against the working end of the device;
ventilating the individual through the medial opening upon determining movement of the wall of the body passageway without removing the working end from the body passageway and while maintaining suction through the distal opening; and
ventilating the ventilating the individual through the distal opening upon failure to detect movement of the wall of the body passageway.
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 timing ventilating the individual with a chest compression to increase effectiveness of both the compression and ventilation.
4. The method of claim 1 , further comprising initially ventilating through the medial opening during application of suction through the distal opening.
5. The method of claim 1 , further comprising, upon detecting movement of the wall of the body passageway, maintaining sufficient suction to temporarily anchor the ventilation device within the body passageway.
6. The method of claim 1 , further comprising a balloon coupled to the working end of the ventilation device where the balloon temporarily anchors the ventilation device within the body passageway.
7. The method of claim 1 , where a proximal portion of the ventilation device further comprises a face mask, where the distance between the face mask and the distal opening is adjustable.
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 1 , further comprising coupling a collection member to the first lumen and collecting bodily fluids in the collection member during suctioning.
12. 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 to move a wall of the body passageway at the distal opening;
ventilating the patient through the second lumen and the medial opening upon determining movement of the wall of the body passageway while maintaining suction through the distal opening and ventilating the patient through the first lumen and the distal opening upon failing to determine movement of the body wall without removing the working end of the ventilation device from the body passageway.
13. The method of claim 12 , 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.
14. The method of claim 12 , further comprising timing ventilating the individual with a chest compression to increase effectiveness of both the compression and ventilation.
15. The method of claim 12 , further comprising initially ventilating through the medial opening during application of suction through the distal opening.
16. The method of claim 12 , further comprising, upon detecting movement of the wall of the body passageway, maintaining sufficient suction to temporarily anchor the ventilation device within the body passageway.
17. The method of claim 12 , further comprising a balloon coupled to the working end of the ventilation device where the balloon temporarily anchors the ventilation device within the body passageway.
18. The method of claim 12 , where a proximal portion of the ventilation device further comprises a face mask, where the distance between the face mask and the distal opening is adjustable.
19. The method of claim 12 , where a proximal portion of the ventilation device further comprises a pressure relief valve to adjust ventilation parameters of the individual.
20. The method of claim 12 , 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.
