Dependent claims

A medical system, comprising:

an endotracheal tube apparatus having a proximal end and a distal end, and further comprising
an endotracheal tube having a proximal end and a distal end, wherein the endotracheal tube is configured to be inserted into a trachea of a human body;
a connection fitting connected to the endotracheal tube, wherein the connection fitting is disposed adjacent the proximal end of the endotracheal tube proximal to the proximal end of the endotracheal tube, and wherein the connection fitting provides the proximal end of the endotracheal tube apparatus;
a ventilation passageway, wherein the ventilation passageway is disposed in the connection fitting and disposed in the endotracheal tube;
an exhaled gas(es) sampling port, wherein the exhaled gas(es) sampling port is configured to be connected to an exhaled gas(es) sampling device configured to detect a presence of carbon dioxide in an exhaled gas(es) sample;
an exhaled gas(es) sampling passageway in fluid communication with the ventilation passageway;
wherein the exhaled gas(es) sampling passageway extends at least in part through the connection fitting, and is in fluid communication with the ventilation passageway of the connection fitting without being disposed in the endotracheal tube;
wherein the exhaled gas(es) sampling passageway is arrangeable in only one of a first arrangement or a second arrangement at a time;
wherein, in the first arrangement, the exhaled gas(es) sampling passageway is in fluid communication with the exhaled gas(es) sampling port;
wherein, in the second arrangement, the exhaled gas(es) sampling passageway is in fluid communication with a device to remove secretions from the exhaled gas(es) sampling passageway;
and
wherein, in either of the first arrangement or the second arrangement, the exhaled gas(es) sampling passageway extends through an openable and closeable valve of the endotracheal tube apparatus.

an endotracheal tube having a proximal end and a distal end, wherein the endotracheal tube is configured to be inserted into a trachea of a human body;
a connection fitting connected to the endotracheal tube, wherein the connection fitting is disposed adjacent the proximal end of the endotracheal tube proximal to the proximal end of the endotracheal tube, and wherein the connection fitting provides the proximal end of the endotracheal tube apparatus;
a ventilation passageway, wherein the ventilation passageway is disposed in the connection fitting and disposed in the endotracheal tube;
an exhaled gas(es) sampling port, wherein the exhaled gas(es) sampling port is configured to be connected to an exhaled gas(es) sampling device configured to detect a presence of carbon dioxide in an exhaled gas(es) sample;
an exhaled gas(es) sampling passageway in fluid communication with the ventilation passageway;
wherein the exhaled gas(es) sampling passageway extends at least in part through the connection fitting, and is in fluid communication with the ventilation passageway of the connection fitting without being disposed in the endotracheal tube;
wherein the exhaled gas(es) sampling passageway is arrangeable in only one of a first arrangement or a second arrangement at a time;
wherein, in the first arrangement, the exhaled gas(es) sampling passageway is in fluid communication with the exhaled gas(es) sampling port;
wherein, in the second arrangement, the exhaled gas(es) sampling passageway is in fluid communication with a device to remove secretions from the exhaled gas(es) sampling passageway;
and
wherein, in either of the first arrangement or the second arrangement, the exhaled gas(es) sampling passageway extends through an openable and closeable valve of the endotracheal tube apparatus;
arranging the exhaled gas(es) sampling passageway in the first arrangement;
connecting the exhaled gas(es) sampling port to the exhaled gas(es) sampling device;
establishing fluid communication between the exhaled gas(es) sampling passageway and the exhaled gas(es) sampling device;
connecting a ventilation device to the connection fitting;
providing ventilation to the human body through the endotracheal tube apparatus;
obtaining exhaled gas(es) from the human body;
moving an exhaled gas(es) sample of the exhaled gas(es) through the exhaled gas(es) sampling passageway to the exhaled gas(es) sampling device;
removing the exhaled gas(es) sampling passageway from fluid communication with the exhaled gas(es) sampling device;
establishing fluid communication between the exhaled gas(es) sampling passageway and the device to remove secretions from the exhaled gas(es) passageway;
and
removing secretions from the exhaled gas(es) sampling passageway with the device to remove secretions from the exhaled gas(es) passageway.
