Witryna13 lip 2024 · Irrespective of the approach chosen by the clinical team, it is imperative to assess work of breathing (WOB) when the patient is weaned from the ventilator. The gold standard for measuring inspiratory WOB is through the Campbell diagram (WOB CAMPBELL) by making use of an esophageal catheter. WitrynaIn this instance, PSV may allow the patient to overcome the imposed work of breathing through a functionally narrow endotracheal tube. There are practical advantages to conducting an SBT through the ventilator: no additional equipment is required; and ventilator alarm and monitoring systems promptly identify weaning intolerance …
