Discontinuation of mechanical ventilation is a two-step process, consisting of readiness testing and weaning:●Readinessn testing – Readiness testing is the evaluation of objective criteria to ndetermine whether a patient might be able to successfully and safely nwean from mechanical ventilation.●Weaningn – Weaning is the process of decreasing the amount of support that the npatient receives from the mechanical ventilator, so the patient assumes an greater proportion of the ventilatory effort. The purpose is to assess nthe probability that mechanical ventilation can be successfully ndiscont...
