Question 1

When should you use the head tilt-chin lift technique during airway management?

Accepted Answer

Use the head tilt-chin lift technique in patients without suspected cervical spine injuries. Place one hand on the forehead and apply gentle backward pressure to tilt the head. Position fingertips under the chin and lift upward to extend the neck, moving the tongue away from the throat and reducing airway obstruction risk.

Question 2

Why is the jaw-thrust maneuver preferred when cervical spine injury is suspected?

Accepted Answer

The jaw-thrust maneuver opens the airway without neck movement, making it ideal for patients with possible spinal injuries. Place fingers behind the mandible angles and apply upward and forward pressure to move the jaw forward. This technique minimizes cervical spine movement while effectively clearing the airway.

Question 3

How do you properly insert and position an oropharyngeal airway?

Accepted Answer

Measure the oropharyngeal airway from the corner of the mouth to the earlobe to select the correct size. Insert the tip facing the roof of the mouth, then rotate 180 degrees to align with the tongue. This positioning prevents tongue obstruction and reduces trauma to oral tissues while ensuring proper airway clearance.

Question 4

What is the E-C clamp technique used for in bag-valve-mask ventilation?

Accepted Answer

The E-C clamp technique creates a tight seal between the mask and patient's face. Form a C-shape with your thumb and index finger around the mask, while the remaining three fingers form an E along the mandible to stabilize the mask. This technique reduces air leaks and ensures adequate ventilation during manual bag-valve-mask delivery.

Question 5

How often should you squeeze the bag during bag-valve-mask ventilation?

Accepted Answer

Squeeze the bag every 5 to 6 seconds during bag-valve-mask ventilation. Observe visible chest rise to confirm adequate ventilation. Bag-valve-mask can be used with or without supplemental oxygen, and combining it with adjuncts like oropharyngeal airways improves ventilation in unconscious patients.

Question 6

What is the primary purpose of an oropharyngeal airway in emergency care?

Accepted Answer

An oropharyngeal airway prevents the tongue from blocking the airway in unconscious patients without a gag reflex. It maintains a clear path for airflow and reduces the risk of airway obstruction. These airway management techniques are foundational skills that may be followed by resuscitation advanced airway management techniques in complex cases.

Question 7

What are the key differences between head tilt-chin lift and jaw-thrust maneuvers?

Accepted Answer

Head tilt-chin lift extends the neck and is used when cervical spine injury is not suspected, while jaw-thrust moves the jaw forward without neck extension for suspected spinal injuries. Head tilt-chin lift is generally more effective for clearing airway obstruction, but jaw-thrust prioritizes spine protection in trauma patients.
