What aspect does 'N' in the LEMON mnemonic address?

The 'N' in the LEMON mnemonic specifically addresses neck mobility, which is a critical aspect to consider during airway assessment. Evaluating neck mobility is crucial because it helps determine the ease or difficulty of intubation. A patient with limited neck mobility may present challenges due to restricted head extension, which can compromise the alignment of the oral, pharyngeal, and laryngeal axes, making intubation more technically difficult. Therefore, assessing neck mobility allows healthcare providers to anticipate potential intubation complications and prepare appropriate strategies or equipment, thus optimizing patient safety and airway management.
