Considering the trend of arterial oxygenation, we can also deduce that the main factor responsible for the increase in PaO2 and SaO2 in all groups supplied with oxygen is the presence of the drapes completely covering the face. In these patients, the only contributing factor to the difference between time4 and the basal time is the covering of the face by drapes; body position and inspiratory oxygen concentration were constant.
This effect leads us to hypothesize that the drapes applied over the face may have facilitated the increase in oxygen concentration in the inspired gases by slowing down its diffusion into the room air. If this mechanism was responsible for the increase in arterial oxygenation, we could also expect an increase in PaCO2 as a consequence of carbon dioxide increase in the air below the drapes, but this event did not happen.
It is possible that carbon dioxide did not increase in the inspired gases because of its higher diffusion compared to oxygen through the drapes, as it occurs at the alveolar-capillary membrane [ 13 ], but we are unable to conclude this.
Furthermore, coronary patients not in the head-down position and breathing room air showed improved arterial oxygenation with the drapes applied over the face. However, the increase in PaO2 and SaO2 was smaller than that observed in patients supplied with oxygen, although the levels of arterial oxygen tension and saturation were still satisfactory.
