Abstract
An airway device is provided that may track the flow of respiratory gases through the device with sensing elements at a plurality of locations along the gas flow path of the device. Such a device may be useful for assessing a variety of clinical states, for adjusting patient ventilator settings, or for determining whether or not an airway device has been properly inserted into a patient airway.
Claims24
A multi-lumen intubation tube comprising:
- a conduit adapted to transfer gas to a patient's lungs comprising a first lumen and a second lumen;
- a first carbon dioxide sensing component disposed on the first lumen;
- and
- a second carbon dioxide sensing component disposed on the second lumen.
A method of manufacturing a multi-lumen intubation tube comprising:
- providing a conduit adapted to transfer gas to a patient's lungs comprising a first lumen and a second lumen;
- providing a carbon dioxide sensing element disposed on the first lumen;
- and
- providing a carbon dioxide sensing element disposed on the second lumen.
A method of determining which lumen is active in a multi-lumen tube comprising:
- inserting a multi-lumen tube into a patient's airway;
- determining a concentration of carbon dioxide gas at a location in a first lumen;
- and
- determining a concentration of carbon dioxide gas at a location in a second lumen,
- wherein the lumen with the higher concentration of carbon dioxide gas is the active lumen.
