Upper Airway Obstruction (Adult) Flashcards
(13 cards)
Recite the UAO (Adult) CPG
What is the key status that triggers this guideline?
An adult patient with audible stridor.
What must be done immediately?
Request MICA, due to risk of life-threatening airway obstruction.
Does this CPG apply to stridor caused by anaphylaxis?
No – refer to CPG A0704 Anaphylaxis.
What two aspects should be assessed initially?
• Acute or chronic onset
• Respiratory status including SpO₂.
What should be done for a conscious patient?
• Encourage to cough
• Give 5 back blows, 5 chest thrusts
• Alternate and monitor.
What actions are taken for an unconscious patient?
• Use laryngoscope & Magill’s forceps

What if the patient loses cardiac output?
Treat per CPG A0201 Cardiac Arrest, including forced ventilations.

Dexamethasone 8 mg IV or IM.

Perform ETI as per CPG A0302 Endotracheal Intubation, and be prepared for cricothyroidotomy per CPG A0303.
what is the pathophsyiology and definition of UAO
Upper Airway Obstruction refers to a partial or complete blockage of the airway above the vocal cords, including the nose, pharynx, or larynx. It can lead to reduced airflow, hypoxia, and potential respiratory failure if not managed promptly.
🚨 Common Causes of UAO:
Infectious: Croup, epiglottitis, tonsillitis
Allergic: Anaphylaxis, angioedema
Foreign body aspiration
Trauma: Burns, swelling, laryngeal injury
Tumour/mass effect
Neurological: Reduced tone in unconscious patients
