An apparatus including a tubular channel having a pathway extending between a proximal end and a distal end of the tubular channel. The proximal end is configured to connect directly or indirectly to an end tidal CO.sub.2 monitor. The distal end has an opening. The apparatus further includes a detection member including a chamber disposed in fluid communication with the pathway of the tubular channel such that gas entering the tubular channel via the opening on the distal end passes into the chamber. A detection element is disposed within the chamber and includes a component that is sensitive to one or more systemic biomarkers such that, upon exposure to a predetermined concentration level of the one or more systemic biomarkers contained in the gas, a state of the detection element experiences a permanent alteration and the detection member indicates that the predetermined concentration level of the one or more systemic biomarkers is present in the gas.

According to a preferred embodiment of the present invention there is provided a bite block assembly adapted for capnography and oxygen delivery to a subject, the bite block assembly (50) including a first capnography passageway adapted for passage therethrough of exhaled breath from the subject to a capnograph and a second oxygen delivery passageway, separate from the first passageway, adapted for passage therethrough of oxygen from an oxygen source to the mouth of the subject.

Systems, devices, and methods are disclosed for the cleaning of an endotracheal tube while a patient is being supported by a ventilator connected to the endotracheal tube for the purpose of increasing the available space for airflow or to prevent the build up of materials that may constrict airflow or be a potential nidus for infection. In one embodiment, a mechanically-actuated endotracheal tube cleaning device is configured to removably receive a visualization member to provide cleaning of the endotracheal tube under direct visualization.

A medical system for assisting with an intubation procedure for a patient. The system comprising airflow sensors configured to obtain data indicative of airflow in the patient's airway and physiological sensors configured to obtain information regarding airflow in the patient's lungs. The system further including a monitoring device communicatively coupled to the airflow sensors and the physiological sensors. The patient monitoring device comprising at least one processor coupled to memory and configured to: provide a user interface on a display and assist the rescuer in determining proper placement of an endotracheal tube, receive the data indicative of the airflow in the patient's airway, receive the physiological information regarding the airflow in the patient's lungs, and determine whether the tube is properly placed based on the received physiological information, and present an output of the determination of whether the ET tube was properly placed.

Various methods and systems for delivery of an ETT for intubation are provided. In one example, an ETT delivery system comprises a rail system, where the rail system comprises at least one rail. In some examples the rail system engages with an ETT and at least partially defines an ETT delivery path. Additionally, the ETT delivery system may further include a delivery mechanism operatively linked with the rail system. Further, a blade may be attached to the rail system. In a further example, the ETT delivery system may comprise an ETT steering mechanism comprising an upper lip and a lower lip, where adjusting the orientation of the lower lip may adjust a tip direction of the ETT.

There is provided herein methods, apparatus and systems for evaluating carbon dioxide (CO.sub.2) concentration in a subject's breath, for example in subjects ventilated with High Frequency Ventilation (HFV), the method includes inserting to a trachea of a subject an endotrachial tube (ETT), sampling breath from an area in the trachea located in proximity to a distal end of the endotrachial tube (ETT) and evaluating one or more CO.sub.2 related parameters of the sampled breath.

The present invention provides an apparatus for nasally delivering a supraglottic jet ventilation and methods of treating breathing disorders by utilizing the apparatus for nasally delivering a supraglottic jet ventilation.

There is provided herein methods, apparatus and systems for evaluating carbon dioxide (CO.sub.2) concentration in a subject's breath, for example in subjects ventilated with High Frequency Ventilation (HFV), the method includes inserting to a trachea of a subject an endotrachial tube (ETT), sampling breath from an area in the trachea located in proximity to a distal end of the endotrachial tube (ETT) and evaluating one or more CO.sub.2 related parameters of the sampled breath.

An intubation device is provided. An intubation device comprises a movable guide configured to guide an insertion of an endotracheal tube into a trachea of a patient, the guide having a guide extension and a guide tip; an external trachea identifier source external to the trachea and disposed on the patient during an intubation, wherein the trachea identifier source generates and transmits a signal; at least one trachea condition sensor disposed on the guide tip to detect the signal generated by the trachea identifier source; and a guide control device operatively coupled to the guide, the guide control device configured to move the guide into the trachea in response to the detected signal.
