Exam 20: Weaning and Discontinuation from Mechanical Ventilation

A patient is being weaned from invasive mechanical ventilation using VC-IMV.The respiratory therapist reviews the following data from the past few hours. What should the respiratory therapist recommend for this patient?

Which mode of ventilation delivers the exact amount of pressure required to overcome the resistive load imposed by the ET tube for the flow measured at the time?

Assess the following data obtained from the spontaneous breathing trials of four patients.Which patient is most likely to be weaned successfully at this time?

An SBT should not continue for longer than _____ minutes.

In which patient would continued use of an artificial airway be necessary?

Which of the following is considered a closed loop mode used for weaning from mechanical ventilation?

A patient being actively weaned from mechanical ventilation currently is receiving the following ventilatory support: pressure support = 15 cm H₂O,spontaneous Vᴛ = 575 mL,spontaneous rate = 14 breaths/min,spontaneous Vᴛ = 500 mL,FɪO₂ = 35%,PEEP = 5 cm H₂O.The arterial blood gas results are: pH = 7.42,PₐCO₂ = 38 mm Hg,PₐO₂ = 94 mm Hg,SₐO₂ = 98%,HCO₃- = 24 mEq/L.What should the respiratory therapist do next?
