Clinical Trial Summary

The aim of this prospective cohort single-center observational study is to determine the impact of hyperoxemia on ventilator-associated pneumonia (VAP) occurrence.

• SpO2 will be continuously recorded in order to determine the percentage of time spent with hyperoxemia.

• Patients with VAP will be prospectively identified.

• Patient characteristics and risk factors for VAP will be prospectively collected.

• Oxidant stress will be prospectively investigated in study patients: glutathion peroxidase (GPX), plasmatic superoxyde dismutase (SOD), total plasmatic antioxidant status (SAT) and urinary 8-isoprostanes will be performed at ICU admission, once a week, and at VAP occurrence.

Patients with VAP will be compared with those with no VAP

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	VAP occurrence	hyperoxemia at ICU admission (PaO2 >120 mmHg)	28 days after ICU admission
Secondary	percentage of time spent with hyperoxemia during ICU stay	hyperoxemia is defined as peripheral O2 saturation (SaO2)>98%, SaO2 will be measured every 30 seconds, and the percentage of time spent with hyperoxemia will be calculated per day.	28 days after ICU admission
Secondary	relationship between hyperoxemia at ICU admission and the presence of acute lung injury (ALI)	the presence of hyperoxemia at ICU admission will be determined using blood gazes (arterial PaO2>120 mmHg). The percentage of patients with hyperoxemia will be compared between patients with Ali, and those with no ALI	28 days after ICU admission
Secondary	percentage of time spent with hyperoxemia during ICU stay, and the presence of acute lung injury	the percentage of time spent with hyperoxemia during ICU stay will be calculated as mentioned above (outcome 2). This percentage will be compared between patient with ALI and those with no ALI	28 days after ICU admission
