Airway Symptoms & Stridor

Recognize a threatened airway early; call help before the airway becomes impossible.

Your objective: explain the approach, recognize important warning signs, then test your recall.

The jobRecognize a threatened airway early; call help before the airway becomes impossible.

  1. Assess ability to speak, swallow secretions, oxygenate, and lie flat while calling senior airway help early.
  2. Differentiate obstruction (foreign body, edema, infection, mass) from lower-airway wheeze.
  3. Prepare a shared airway plan: primary approach, backup, and surgical-airway rescue; use local protocols.

Stridor, drooling, muffled voice, rapidly changing voice, or escalating work of breathing can signal upper-airway failure.

Do not agitate, lie flat, or repeatedly instrument a patient who is maintaining a precarious airway.

Impending upper-airway obstruction Critical

Key: Stridor at rest, drooling, muffled voice, exhaustion, or altered mentation requires immediate expert airway management.

Anaphylaxis / angioedema Critical

Key: Treat as anaphylaxis when systemic allergic features or airway progression are present; do not wait for rash.

Epiglottitis / deep-neck-space infection Critical

Key: Toxic appearance, odynophagia out of proportion, trismus, neck swelling, or voice change; avoid forceful examination.

Foreign body aspiration Critical

Key: Sudden onset, unilateral findings, choking, or persistent symptoms after a choking event.

Croup, laryngitis, vocal-cord dysfunction Common

Key: Still reassess after therapy; a quiet or tiring patient is not reassuring.

Tick what your patient has — the banner updates as you go.

Tempo, choking event, allergen/ACE-inhibitor exposure, fever and odynophagia

Voice change, drooling, dysphagia, neck surgery/radiation, immunosuppression

Prior difficult airway, asthma/COPD, inhalation injury

Work of breathing, stridor at rest, ability to phonate and manage secretions

Oral/neck swelling only if safe; trismus, tongue elevation, urticaria

Avoid upsetting a child with suspected epiglottitis; keep position of comfort

Immediate

  • Continuous monitoring and airway equipment; capnography when feasible
  • Flexible visualization or imaging only when the airway is stable and expert teams agree

Targeted

  • CT neck with contrast for stable suspected deep-neck infection
  • CXR/neck radiography only when it will not delay airway care

Do not delay

  • Airway intervention for a scanner, blood work, or a perfect diagnosis
Medication safety reminder

Use this as a first-pass prompt; verify all medications, doses, concentrations, contraindications, weight, pregnancy status, and local protocols before administration.

Check indication, allergy, route, renal/hepatic risk, interactions, monitoring, and local formulary.

Discharge

  • Clearly benign cause, resolved symptoms, normal observation period, and reliable return precautions.

Admit / ENT / anesthesia

  • Persistent stridor, suspected infection, recurrent edema, or uncertain airway trajectory.

Resuscitation / operating room

  • Threatened airway, rapidly progressive swelling, inhalation injury, or foreign body with obstruction.

Use objective reassessment and the local pathway.

Before the next decision · reassess and hand over

Use these learning prompts with the presentation’s pathway. They are not discharge criteria.

  1. Reassess: compare symptoms, observations and examination with the initial assessment and response to treatment.
  2. Warning signs for Airway Symptoms & Stridor:
    • Stridor at rest or silent/tiring airway
    • Drooling, tripod position, inability to lie flat
    • Rapidly progressive face/tongue/neck swelling
    • Muffled voice, trismus, toxic appearance
    • Burns, soot, enclosed-space smoke exposure
  3. Reconsider: check unresolved findings and alternative explanations, including the pitfalls below.
  4. Escalate: communicate deterioration, uncertainty or needs beyond the current setting.
  5. Plan the transition: identify outstanding results, responsibility for follow-up, patient understanding and specific return advice.

Clinical Pearls

  • A calm, upright patient is often buying time—do not remove their compensations.
  • The best airway plan includes a backup and surgical rescue before the first attempt.

Pitfalls

  • Repeated tongue-depressor examination in a threatened infectious airway.
  • Calling stridor “wheeze” and delaying upper-airway planning.
PRACTICE REFRESHER

Rapid recall

Test your first action and the dangerous diagnoses before revealing the answer.

01 · First move

Before you scroll, what needs to happen first?

02 · Immediate threats

Name at least two diagnoses that cannot wait.
