How does obesity affect airway management in EMS?

• A. It increases difficulty achieving a proper seal, may require higher airway pressures, and can complicate ventilation.
• B. It makes ventilation easier.
• C. It reduces the need for oxygen.
• D. It has no impact.

Answer: (B)

Obesity adds several challenges to airway management in the field. Excess tissue in the face and neck, along with reduced chest wall compliance and higher oxygen consumption, makes it harder to keep the airway open and to ventilate effectively. A good mask seal is more difficult to achieve because of facial adiposity and limited neck mobility, and the environment and patient size can necessitate higher airway pressures to deliver adequate tidal volumes. The combination increases the risk of rapid desaturation, so thorough preoxygenation and careful airway planning are essential. In practice, anticipate a potentially difficult bag‑mask ventilation, consider a ramped position to improve alignment of the airway, and be ready to escalate to adjuncts or a definitive airway if needed. This is why the statement about increasing difficulty and the need for higher pressures and ventilation adjustments best describes the impact of obesity.
