Phase:

PHASE2

Brief Summary

During weaning the work of breathing is transferred from the ventilator back to the patient. Approximately 40% of the time on ventilators is spent weaning. Studies support the use of screening protoco...

Detailed Description

In the context of a multicentre, pilot trial in 100 elderly (\>/= 65 years) critically ill adults comparing two strategies to identify weaning candidates ('once daily' vs. 'at least twice daily' scree...

Eligibility Criteria

Inclusion

  • The investigators will include:
  • elderly (age \>/= 65 years) critically ill adults
  • receiving invasive mechanical ventilation for at least 24 hours who can breathe spontaneously on Pressure Support (PS) or trigger breaths on volume or pressure Assist Control (AC), volume or pressure Synchronized Intermittent Mandatory Ventilation (SIMV) ± PS, Pressure Regulated Volume Control (PRVC) or Airway Pressure Release Ventilation (APRV).
  • patients must be receiving \</= 70% inspired oxygen
  • and a positive end-expiratory pressure of \</= 12 cm H2O (Table 2). .

Exclusion

  • The investigators will exclude patients who have already undergone extubation or an SBT, are unlikely to benefit (e.g. moribund, expected brain death), on automated weaning modes, participating in studies with a weaning protocol, and those who can not be optimized with regard to sedation and mobilization.
  • Specifically, we will exclude patients:
  • admitted after cardiopulmonary arrest or with brain death or expected brain death,
  • who have evidence of myocardial ischemia in the 24 hour period before enrollment,
  • who have received continuous invasive mechanical ventilation for \>/= 2 weeks,
  • who have a tracheostomy in situ at the time of screening,
  • who are receiving sedative infusions for seizures or alcohol withdrawal,
  • who require escalating doses of sedative agents,
  • who are receiving neuromuscular blockers or who have known quadriplegia, paraplegia or 4 limb weakness or paralysis preventing active mobilization (e.g., active range of motion, exercises in bed, sitting at edge of bed, transferring from bed to chair, standing, marching in place, ambulating),
  • who are moribund (e.g., at imminent risk for death) or who have limitations of treatment (e.g., withdrawal of support, do not reintubate order, however, do not resuscitate orders will be permitted),
  • who have profound neurologic deficits (e.g. large intracranial stroke or bleed) or Glasgow Coma Scale (GCS) \</= 6,
  • who are using modes that automate SBT conduct,
  • who are current enrolled in a confounding study that includes a weaning protocol,
  • who were previously enrolled in this trial,
  • patients who have already undergone an SBT or
  • patients who have already undergone extubation \[planned, unplanned (e.g. self, accidental)\] during the same ICU admission.
