Absorption atelectasis often develops from denitrogenation in patients who have low ventilation-perfusion ratios (maldistribution of ventilation), and are administered supplemental oxygen.
In order to prevent this problem, I think that the following procedures should be adopted: pay attention to the pressure values and times, as well as to concentrations in the gas mixtures that are applied during the recruitment manoeuvre; give these values in the studies reported; and to prevent absorption atelectasis, hold the oxygen concentration in the oxygen-gas mixtures at the lowest level possible.
The results from the control group (100% oxygen) may have been negatively biased by the effect of absorption atelectasis referred to above, as a result of the displacement of inert pulmonary gases by 100% oxygen inhalation (Rothen et al 1995).
In a computer model of absorption atelectasis (16), the time to collapse in a lung unit filled with 30% oxygen was estimated to be three hours.
