Ning et al reported a nomogram for predicting mechanical ventilation for a patient with Guillain-Barre Syndrome. This can help to identify a patient who may benefit from more aggressive management. The authors are from Sichuan University and the Seventh People's Hospital of Chengdu in China.
Patient selection: Guillain-Barre syndrome
Parameters:
(1) length of hospital stay in days
(2) glossopharyngeal and vagus nerve involvement
(3) neutrophil to lymphocyte ratio (NLR)
(4) Hughes functional grading scale (HFGS) on admission (from 0 healthy to 6 dead)

total score =
= SUM(points for all of the parameters)
Interpretation:
• minimum score: 0
• maximum score: 352.3
• The higher the score the greater the risk for mechanical ventilation.
X =
= (0.02484 * (score)) - 6.26
probability of mechanical ventilation =
= 1 / (1 + EXP((-1) * X))
