Basic structure and usage of Disposable Respiration Product

Endotracheal Tube is a medical device that is inserted into a patient's trachea or bronchi to create a temporary artificial breathing passage for patients, especially patients who cannot breathe on their own. Mainly made of non-toxic PVC, used in hospitals and clinics. Next, let's take a look at the basic structure and usage of Endotracheal Tube.

What is the basic structure of Endotracheal Tube?

Common Endotracheal Tube heads have one or two cuffs, which can be inflated to secure the cannula and seal the airway. The cannula body is usually made of polymer material, and a steel wire coil is embedded in the tube body to improve radial strength and axial flexibility. Some Endotracheal Tube tube bodies have anti-laser materials or layers to resist laser exposure. A tube is inserted into a patient's trachea through the nose, mouth, or percutaneously. One end is connected to an anesthesia ventilator through a breathing circuit to maintain the patient's breathing. Supplied sterile for single use.

How to use Endotracheal Tubes.

Endotracheal Tubes were inserted transorally into the trachea after exposure to the glottis under direct vision with the aid of a laryngoscope. Tilt the patient's head back, hold the lower jaw forward and upward with both hands to open the mouth, or use the right thumb to face the lower dentition and the index finger to face the upper dentition, and use the rotational force to open the mouth. Hold the laryngoscope handle with the left hand and put the laryngoscope blade into the oral cavity from the right corner of the mouth, push the tongue body to the side and then slowly advance it, and the uvula can be seen. Lift the lens vertically forward until the epiglottis is exposed. Raise the epiglottis to reveal the glottis. If a curved lens is used for intubation, the lens is placed at the junction of the epiglottis and the base of the tongue (the epiglottis valley), and the lens is forced forward and upward to make the hyoid-epiglottic ligament tense, and the epiglottis is raised and close to the laryngeal lens, that is, the glottis is exposed. If a straight lens is used for intubation, the epiglottis should be directly provoked, and the glottis can be exposed.

Hold the middle and upper sections of Endotracheal Tube with the thumb, index finger, and middle finger of the right hand as if holding a pen, enter the mouth from the right corner of the mouth, and move the tube end to the laryngeal blade when the Endotracheal Tube is close to the larynx. The narrow space between the tube walls monitors the advancing direction of the Endotracheal Tube and inserts the Endotracheal Tube tip into the glottis accurately and lightly. When using the stylet for intubation, after the tip of the Endotracheal Tube has entered the glottis, the stylet should be pulled out and then the Endotracheal Tube should be inserted into the trachea. The depth of insertion of Endotracheal Tube into the trachea is 4-5 cm for adults, and the distance from the tip of the Endotracheal Tube to the incisors is about 18-22 cm.

After intubation is complete, confirm that Endotracheal Tube has entered the trachea for re-fixation. Confirmation methods are: when the chest is compressed, there is airflow at the Endotracheal Tube mouth. During artificial respiration, bilateral thoracic rise and fall can be seen symmetrically, and clear alveolar breath sounds can be heard. For example, when using transparent Endotracheal Tubes, the wall of the tube is clear when inhaling, and a clear "white fog"-like change can be seen when exhaling. If the patient is breathing spontaneously, the breathing bag can be seen to expand and contract with the breathing after receiving the anesthesia machine. If the end-tidal ETCO2 can be monitored, it will be easier to judge, and the ETCO2 graph will be displayed to confirm that it is correct. Endotracheal Tubes were inserted transnasally into the trachea under non-photopic conditions. Spontaneous breathing must be retained during intubation, and the direction of Endotracheal Tubes can be judged according to the strength of the exhaled airflow. Use Endotracheal Tube with a suitable diameter, and insert the tube into the nasal cavity with the right hand. During the intubation process, listen to the strength of the exhaled airflow while moving forward, and at the same time adjust the position of the patient's head with the left hand to find the position with the strongest exhaled airflow. Endotracheal Tubes are advanced rapidly when the glottis is open.

When Endotracheal Tube entered the glottis, the propulsion resistance was reduced, and the exhaled airflow was obvious. Sometimes the patient had a cough reflex. When the anesthesia machine was connected, the breathing bag could be seen expanding and contracting with the patient's breathing, indicating that Endotracheal Tubes were inserted into the trachea. Such as the disappearance of exhaled airflow after the advancement of Endotracheal Tube, is the performance of insertion into the esophagus. The Endotracheal Tube should be withdrawn to the nasopharynx, and the tip of the Endotracheal Tube should be tilted upward by tilting the head slightly, which can be aligned with the glottis to facilitate insertion.
