  1. Fuchs et al.
  2. Intubating conditions are excellent when all variables are excellent; good (all variables are excellent or good); and poor (at least a single variable under “poor”)
  3. Laryngoscopy: easy (jaw relaxed, smooth laryngoscope blade insertion); fair (jaw is semi-relaxed, mild resistance to laryngoscope blade insertion); and difficult (jaw is not relaxed, patient is resisting the insertion of the laryngoscope blade)
  4. Not more than 2 weak contractions and/or movement for less than 5 s
  5. §More than 2 contractions and /or movement for more than 5 s
