A grade 3 on the upper lip bite test (patient unable to bite upper lip with lower teeth) has LR+ 14 for<unk><unk>  intubation
An<unk>  assessment score based on criteria of the LEMON method is able to successfully stratify the risk of intubation<unk> y in the emergency department.
Look at the patient externally for characteristics that are known to cause<unk>  laryngoscopy, intubation or ventilation

Short neck
Micrognathia
Prior surgery

3 - Ideally the distance between the patient's incisor teeth should be at least 3 finger breadths
3 - Distance between the hyoid bone and the chin should be at least 3 finger breadths
2 - Distance between the thyroid notch and the floor of the mouth should be at least 2 finger breadths
1 - Lower jaw should not sublux more than 1cm
The patient sits upright, opens mouth and protrudes tongue
Grades are based on visibility of the uvula, posterior pharynx, hard, and soft palate
Assess for conditions leading to<unk>  obstruction such as Peritonsillar Abscess (PTA), trauma, or Epiglottitis.
Patient places chin down onto their chest and extend their neck.
Remove the hard collar and provide manual stabilization in trauma patients.
Poor neck mobility impacts ability to have<unk>  access alignment.
