"Oropharyngeal Airway (Berman Type)" refers to the Berman-type oropharyngeal airway, which is a specific type of oropharyngeal airway. Here is an introduction to it:
Design Features
Shape and Structure: The Berman-type oropharyngeal airway usually has a unique curved shape. This shape is specifically designed to better fit the physiological structure of the human oropharynx. It generally has a relatively wide flange, which helps prevent the airway from slipping completely into the oral cavity during use, making it convenient for medical staff to operate and fix.
Material Properties: It is mostly made of soft and highly elastic medical-grade plastic or rubber. This material can ensure that when inserted into the oral cavity and pharynx, it will not cause excessive irritation or damage to the tissues. At the same time, it has sufficient toughness to resist external force deformation to a certain extent, ensuring that the airway maintains a stable shape and function during use.
Size Specifications: To meet the needs of patients of different ages and body types, the Berman-type oropharyngeal airway is available in a variety of sizes. For example, for pediatric patients, the size is relatively small, with a thinner diameter and a shorter length; while for adult patients, there are larger-sized airways to ensure that enough ventilation space and effect can be provided.
Applicable Scenarios
Emergency Situations: At the emergency medical rescue scene, such as when a patient is in a coma due to accidental incidents like traffic accidents or fires, or when a patient suddenly experiences cardiac arrest and immediate cardiopulmonary resuscitation is required, the Berman-type oropharyngeal airway can be quickly inserted into the patient's oral cavity. It effectively prevents the tongue from falling backward and blocking the airway, buying precious time for the patient's breathing and creating conditions for subsequent professional medical treatment.
During Anesthesia: During the induction and recovery periods of anesthesia in surgical operations, the patient's muscles are in a relaxed state, and airway obstruction is likely to occur. The Berman-type oropharyngeal airway can be used to maintain the patency of the patient's airway, ensure the smooth exchange of anesthetic gases, and help anesthesiologists manage respiration better, ensuring the patient's respiratory safety during the anesthesia process.
Nursing of Special Patients: For some patients who are unconscious and have weakened or disappeared swallowing reflexes due to neurological diseases, poisoning, or other reasons, during daily nursing or transportation, the Berman-type oropharyngeal airway can help keep the airway unobstructed and reduce the risk of complications such as airway obstruction and pulmonary infection.
Precautions for Use
Select the Appropriate Size Correctly: Before use, the appropriate size of the Berman-type oropharyngeal airway must be selected according to the patient's age, body type, oral cavity size, and other factors. If the size is too small, it may not be able to open the airway effectively; if the size is too large, it may cause damage to the oral and pharyngeal tissues and even lead to airway obstruction.
Standard Insertion Operation: When inserting, the patient's head should be turned to one side first, and foreign matters such as secretions and vomitus in the oral cavity should be removed. Then, insert the airway with the curved end upward along the upper surface of the tongue. When it is inserted to a certain depth, rotate it 180 degrees so that the curved end is downward and located behind the base of the tongue. The operation should be gentle during the process, and avoid inserting it with force to prevent damage to the mucous membranes and tissues of the oral cavity, gums, throat, and other parts.
Closely Observe the Patient: During the use of the Berman-type oropharyngeal airway, closely observe the patient's respiratory status, complexion, oxygen saturation, and other indicators to ensure that the airway is unobstructed and gas exchange is normal. If the patient shows abnormal conditions such as coughing, dyspnea, and cyanosis, immediately check whether the airway is displaced, blocked, or dislodged, and take corresponding measures in a timely manner, such as adjusting the position of the airway and removing airway foreign bodies.
