oropharyngeal airway การใช้

• Therefore, an oropharyngeal airway must be sized appropriately.
• An oropharyngeal airway may cause gagging and vomiting.
• Oropharyngeal airways are indicated only in vomit and potentially lead to an obstructed airway.
• An NPA is often used in conscious patients where an oropharyngeal airway would trigger the gag reflex.
• Such devices include the laryngeal mask airway, cuffed oropharyngeal airway and the esophageal-tracheal combitube ( Combitube ).
• An oropharyngeal airway is used during bag-valve-mask ventilation to prevent oropharynx soft tissues from blocking the airway.
• Higher level practitioners such as emergency medical service personnel may use more advanced techniques, from oropharyngeal airways to intubation, as deemed necessary.
• If the risk of asphyxiation is deemed high, doctors may use various devices ( such as an oropharyngeal airway, nasopharyngeal airway or endotracheal tube ) to safeguard the airway.
• Oropharyngeal airways come in a variety of sizes, from infant to adult, and are used commonly in pre-hospital emergency care and for short term airway management post anaesthetic or when manual methods are inadequate to maintain an open airway.
• Current evidence suggests that for out-of-hospital cardiac arrest, basic airway interventions ( head-tilt chin-lift maneuvers, bag-valve-masking or mouth-to-mouth ventilations, oropharyngeal airways ) resulted in greater short-term and long-term survival, as well as improved neurological outcomes in comparison to advanced airway interventions ( endotracheal intubation, laryngeal mask airway, all types of supraglottic airways ( SGA ), and trans-tracheal or trans-cricothyroid membrane airways ).
• EMT is the main entry level of EMS . The procedures and skills allowed at this level are generally non-invasive such as bleeding control, positive pressure ventilation with a bag valve mask, oropharyngeal airway, nasopharyngeal airway, supplemental oxygen administration, taking vital signs, pulse oximetry, glucometry, oral suctioning, eye irrigation, cardio-pulmonary resuscitation ( CPR ), use of an automated external defibrillator ( AED ), splinting ( including full spinal immobilization ), traction splinting, deliver in a normal childbirth, assist with a complicated birth, and medication administration ( such as epinephrine auto-injectors, oral glucose gel, aspirin, CPAP . Training requirements and treatment protocols vary from area to area.
