Airway Management and Ventilation
Airway management and ventilation is the body of emergency-medicine knowledge concerned with keeping the airway open and ensuring adequate oxygenation and carbon dioxide elimination in acutely ill or injured patients. It spans rapid bedside assessment of airway patency and risk, the techniques used to secure and protect the airway, and the modes of ventilatory support that follow.
Definition
Airway management and ventilation refers to the assessment, establishment, protection, and maintenance of a patent airway together with the provision of adequate oxygenation and ventilation, using manual manoeuvres, supraglottic and tracheal devices, and invasive or non-invasive positive-pressure support as the clinical situation requires.
Scope
This area orients the reader to four linked topics: assessing the airway and predicting difficulty, performing rapid sequence intubation, recognising and managing the difficult airway, and supporting breathing with non-invasive ventilation. It frames these as reference knowledge about how emergency clinicians conceptualise the airway, not as procedural instruction or dosing guidance.
Sub-topics
Core questions
- Is the airway patent, protected, and at risk of deterioration?
- Does the patient need oxygenation, ventilation, or a secured airway, and how urgently?
- How can difficulty with mask ventilation, intubation, or a surgical airway be anticipated?
- When can breathing be supported non-invasively rather than by intubation?
Key concepts
- Airway patency and protection
- Oxygenation versus ventilation
- Predicted difficult airway
- Rapid sequence intubation
- Supraglottic and tracheal devices
- Front-of-neck access
- Positive-pressure ventilation
- Pre-oxygenation and apnoeic oxygenation
Mechanisms
The airway can be obstructed at the level of the pharynx, larynx, or lower airways, and ventilation can fail through inadequate respiratory drive, mechanical limitation, or gas-exchange impairment. Emergency airway practice addresses these by first opening and protecting the airway, then matching the intervention to the deficit: oxygen and positive pressure for failing gas exchange, and a secured tracheal airway when protection or controlled ventilation is required. Because intubation and positive-pressure ventilation carry their own hazards, including aspiration during induction and ventilator-induced lung injury, the field emphasises anticipation, planned escalation, and limiting harm from the interventions themselves.
Clinical relevance
Failures of airway management are a recognised source of avoidable harm in emergency and anaesthetic care, which is why structured assessment, planned escalation, and team preparation are central themes. This area describes how clinicians reason about the airway and breathing as a domain of knowledge; it is not a substitute for trained, supervised practice or for institutional protocols.
Epidemiology
The Fourth National Audit Project documented that major airway complications, though uncommon relative to the number of airways managed, are disproportionately associated with death and brain damage and frequently involve gaps in assessment, planning, or rescue. Such audit data have shaped the emphasis on anticipating difficulty and rehearsing rescue strategies.
History
Modern emergency airway management grew out of mid-twentieth-century anaesthetic advances, including the description of cricoid pressure and bedside signs to predict difficult intubation, and was later systematised by difficult-airway guidelines and national audits that linked outcomes to process. Parallel advances in mechanical and non-invasive ventilation reshaped how breathing is supported once the airway is addressed.

Frequently asked questions
- What is the difference between oxygenation and ventilation in airway care?
- Oxygenation is the delivery of oxygen to the blood, while ventilation is the movement of air that clears carbon dioxide; a patient can have one problem without the other, and interventions are chosen accordingly.
- Why is anticipating a difficult airway emphasised so strongly?
- National audit data link a large share of severe airway complications to unrecognised difficulty and absent rescue plans, so structured prediction and pre-planned escalation are treated as core safety practices.
