Identify the item in the below denote image? Oral Pharyngeal Airway (OPA) Individual Sizes

Appeared in: AIIMS Delhi NO - 2018

Explanation

  • The device shown in the image is an Oropharyngeal Airway (OPA), also called a Guedel airway.
  • It is a rigid, curved plastic tube inserted into the mouth of an unconscious patient to maintain a patent airway.
  • Its function is to prevent the tongue from displacing backward and obstructing the oropharynx.
  • The visible features—a flange, a bite block, and a curved body—are all characteristic of an OPA.

Why Other Options Were Wrong

  • Option B: An NPA (Nasopharyngeal Airway) is a soft, flexible tube inserted through the nose, which is visually and functionally different from the rigid oral device shown.
  • Option C: An LMA (Laryngeal Mask Airway) is a more complex supraglottic airway device with an inflatable mask that seals around the laryngeal inlet. The device in the image is a simple adjunct, not an LMA.
  • Option D: IGAM is not a standard acronym for an airway device. It is likely a typo for i-gel. An i-gel is a supraglottic airway with a soft, non-inflatable gel cuff, which looks very different from the rigid plastic OPA.

Clinical Relevance
  • Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Identification of basic airway management adjuncts as background academic context rather than a clinical decision trigger.
  • Correctly identifying airway adjuncts is a fundamental skill in emergency care and anesthesia to prevent life-threatening hypoxia.
  • Proper sizing of an OPA is critical. It is measured from the corner of the patient's mouth to the angle of the jaw. An incorrectly sized OPA can worsen airway obstruction.
  • OPAs should only be used in deeply unconscious patients without a gag reflex. Inserting an OPA in a patient with an intact gag reflex can induce vomiting and aspiration.
How to Approach the Question
  • First, carefully examine the image provided. Note the key features of the device: its shape (J-curved), material (rigid plastic), and components (flange at one end).
  • Next, read the options provided: OPA, NPA, LMA, and IGAM.
  • Recall the definitions and appearances of each of these airway devices.
  • Compare the visual features from the image with your knowledge of the options. The rigid, J-shaped oral device matches the description of an Oropharyngeal Airway (OPA).
  • Eliminate the other options based on their distinct characteristics: NPA is soft and nasal, LMA has an inflatable mask, and i-gel (assuming IGAM is a typo) has a soft gel cuff.
Concept Tested & Keywords
  • Concept Tested: Identification of basic airway management adjuncts.
  • Stem keywords: Identify, item, image
  • Lead-in keywords: NOT
  • Clinical cues: The image shows a rigid, J-shaped medical device, which is a key feature of an OPA.
  • Negative lead-in flag: NOT changes the reasoning strategy; look for the exception or incorrect statement rather than the true statement.
