|---|---|---|
| Is oxygen induced lung injury a concern when placing a patient on mechanical ventilation? |
|
NS |
| YES, a major concern |
126 (59%) |
|
| due to the high incidence of injury |
13 (6%) |
|

|
| YES, but not a major concern |
80 (37%) |
|
| NO, it is not a concern |
9 (4%) |
|
| In your opinion, which one of the following two situations poses a greater threat of lung injury for mechanically ventilated patients? |
|

| High FiO2 |
35 (16%) |
|
| High tidal volumes and high ventilator pressures |
173 (81%) |
|
| Don't know |

|
| In situations when maximal SaO2 achievable is low (±85%) or when FiO2 requirements are high, do you assess indices of tissue oxygenation? |
|
P = 0.05 |
| NO |
91 (43%) |
|
| YES, lactate |
88 (42%) |
|
| YES, microcirculation with OPS/SDF imaging |

|
| YES, SvO2 |
6 (3%) |
|
| YES, other | 2 (1%) |
NS, not significant; FiO2, fractions of inspired oxygen; OPS, orthogonal polarization spectral; SDF, sidestream dark field; SaO2, arterial oxygen saturation; SvO2, mixed venous oxygen saturation.
