An Assessment of the Feasibility and Safety of Conservative Oxygen Therapy in Critically Ill Patients

July 9, 2013 updated by: Rinaldo Bellomo, Austin Health

A Before-and-after Assessment of Conservative Oxygen Therapy vs. Standard Care in Critically Ill Mechanically Ventilated Patients

The investigators hypothesize that it is feasible and safe to deliver a conservative approach to oxygen therapy in mechanically ventilated critically ill patients (a tiem frame of, on average,10 days).

Conditions

Intervention / Treatment

Detailed Description

  1. Identify patients likely to require ventilation until the day after tomorrow (a time frame of 36 hours of average)
  2. Deliver a conservative oxygen therapy protocol while in ICU (a time frame on average of 10 days)
  3. Target an oxygen saturation between 90 and 92%
  4. Adjust FiO2 to achieve target SaO2 at all times
  5. Assess percentage of time patient is within target
  6. Assess for safety of this approach
