- expected to be ventilated until the day after tomorrow (a tiem frame of, on average 48 hours)
Exclusion Criteria:
- expected to be off mechanical ventilation today or tomorrow
- carbon monoxide poisoning
- necrotizing fasciitis
Sites / Locations
- Austin Hospital

standard care
conservative O2 therapy
Arm Description
normal treatment
a value of 90-92% O2 saturation will be targeted
Outcomes
Primary Outcome Measures
Difference in PaO2/FiO2 ratio from baseline to worst value
Pao2/FiO2 ratio will be measured regularly and compared during standard care and the intervention period (a time frame of, on average, 10 days)
Secondary Outcome Measures
Lactate
blood lactate will be measured regularly and assessed during standard care and the intervention period

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