Airway Management Basics: the method, the errors, and the exam

What the skill is for

Airway management basics come first in every emergency assessment because nothing else matters if air cannot reach the lungs. Before checking breathing, circulation, or running any other assessment, the nurse establishes and confirms a patent airway. This applies to the unresponsive patient found on the floor, the post-seizure patient, the sedated patient after a procedure, and the trauma patient with facial injuries.

The skill sits at the foundation of basic life support and underpins every advanced airway intervention that follows, from bag-valve-mask ventilation to intubation. A nurse who cannot rapidly open and assess an airway cannot safely proceed to any of those next steps, which is why it is drilled as a discrete, repeatable motor skill rather than something learned only in theory.

The method, step by step

For a patient with no suspected neck or spinal injury, use head-tilt chin-lift: place one palm on the forehead and tilt the head back gently while two fingers of the other hand lift the bony part of the chin upward. This moves the tongue off the posterior pharyngeal wall, which is the most common cause of airway obstruction in an unresponsive patient.

If trauma, a fall, or any mechanism suggesting cervical spine injury is present, use jaw thrust instead: without tilting the head, place fingers behind the angle of the jaw on both sides and push the jaw forward. This opens the airway while keeping the cervical spine in a neutral, stable position.

Once the airway is open, assess breathing. If the patient remains unconscious and needs airway support beyond positioning, insert an oropharyngeal airway sized from the corner of the mouth to the earlobe, curved side down, then rotated into place as it passes the soft palate.

Where it goes wrong

The most common error is defaulting to head-tilt chin-lift on a trauma patient without checking mechanism of injury first, which risks worsening an unstable cervical fracture. Always ask, however briefly, whether the presentation could involve the neck before choosing the manoeuvre.

The second common error is inserting an oral airway into a patient who is not fully unconscious. Because it presses on the tongue base, an oral airway stimulates the gag reflex in anyone with intact protective reflexes; in a semi-conscious or lightly sedated patient this triggers vomiting and increases aspiration risk rather than protecting against it. If the patient gags on insertion or attempted insertion, remove it and consider a nasopharyngeal airway instead, which is far better tolerated in a patient who is not deeply unconscious.

A third error is under-extending the neck in an infant, whose relatively large occiput already flexes the neck forward; a neutral or slightly extended sniffing position is correct, and the adult degree of tilt can actually obstruct an infant's airway.

Practising it deliberately

Practise both manoeuvres on a manikin until the hand positions are automatic, because in a real emergency there is no time to consciously recall finger placement. Alternate scenarios: an unresponsive medical patient, then a fall victim with a head laceration, so the decision between head-tilt and jaw thrust becomes reflexive rather than reasoned each time.

Practise sizing an oral airway against a partner or manikin from memory, corner of mouth to earlobe, and practise the insertion technique of inserting it upside down and rotating 180 degrees as it clears the tongue, which avoids pushing the tongue further back. Time yourself opening an airway and getting a first breath in; speed matters as much as correctness in an actual arrest.

Applying it on the exam

NCLEX questions on this topic usually present a scenario and ask which action comes first, or which technique is safest given the mechanism described. A question describing a patient found unresponsive after a fall down stairs is testing whether you choose jaw thrust over head-tilt chin-lift; missing the fall detail and defaulting to the more familiar manoeuvre is the trap.

Questions about oral airways typically test the gag reflex principle directly, asking what to do if a patient bites down on or gags against an inserted airway, or which patient is an appropriate candidate for one. The expected reasoning is always level of consciousness first: if the patient has any gag response, an oral airway is the wrong choice.

A worked example

A nurse finds a patient unresponsive in bed with no history of trauma. The correct first action is head-tilt chin-lift, followed by a look-listen-feel breathing assessment. Breathing is absent, so the nurse calls for help, begins compressions per protocol, and prepares an oral airway sized from the corner of the mouth to the earlobe once the team arrives with a bag-valve-mask.

Change one detail: the same patient is found at the bottom of a staircase with a head wound. Now jaw thrust replaces head-tilt chin-lift throughout the sequence, and cervical spine precautions are added, including manual in-line stabilisation until the spine is cleared or immobilised. The airway goal is identical; the manoeuvre changes because the mechanism of injury changes the risk calculus.
