Which statement correctly defines RODS in the context of airway management?

• A. R-restricted mouth opening; O-obstruction/obese or late pregnancy; D-distorted or disrupted airway; S-stiff or increased airway pressure
• B. R-rapid airway evaluation; O-obstacle; D-distortion; S-saturation
• C. R-resisted oxygen delivery; O-oral airway; D-diaphragm; S-spinal immobilization
• D. R-respiratory distress; O-obstructive; D-diameter; S-sedation

Answer: (A)

RODS is a mnemonic used to identify factors that predict a difficult airway during airway management. The R stands for restricted mouth opening, which makes laryngoscope insertion and blade control harder. The O covers obstruction, obesity, or late pregnancy, highlighting situations where airway patency or ventilation can be compromised and access is more challenging. The D stands for distorted or disrupted airway, such as trauma or abnormal anatomy that complicates intubation. The S represents stiff or increased airway pressure, indicating poor chest wall compliance or high airway pressures that hinder ventilation and positioning of devices. Recognizing these factors helps you plan the approach, ensure appropriate equipment is ready, and consider alternative airway strategies. Other options include terms that aren’t part of this mnemonic, so they don’t accurately define RODS.
