Clinical criteria used to determine readiness for trials of spontaneous breathing

Clinical criteria used to determine readiness for trials of spontaneous breathing
Required criteria
  1. The cause of the respiratory failure has improved
  1. PaO2/FiO2 ≥150* or SpO2 ≥90% on FiO2 ≤40% and PEEP ≤5 cmH2O
  1. pH >7.25
  1. Hemodynamic stability (no or low dose vasopressor medications)
  1. Able to initiate an inspiratory effort
Additional criteria (optional criteria)
  1. Hemoglobin ≥7 g/dL
  1. Core temperature ≤38 to 38.5°C
  1. Mental status awake and alert or easily arousable

PaO2: arterial oxygen tension; FiO2: fraction of inspired oxygen; SpO2: arterial oxygen saturation; PEEP: positive end-expiratory pressure.

* A threshold of PaO2/FiO2 ≥120 can be used for patients with chronic hypoxemia. Some patients require higher levels of PEEP to avoid atelectasis during mechanical ventilation.
