In this review we try to define the pulmonary lesions caused by mechanical ventilation that may benefit from the main recruitment strategies proposed, both in the case of intensive respiratory care patients as in patients under anesthesia.

The most common pulmonary lesions caused by mechanical ventilation are: barotrauma, volutrauma, atelectrauma and biotrauma. There are strategies for alveolar recruitment, some of which are recruitment maneuvers in themselves according to the pressure values used , such as: an increase in PEEP values, sustained insufflation, sighing, resorting to the benefits of spontaneous breathing, high frequency oscillating ventilation, ventilation with biological variability maintaining constant minute volume, prone position, differential ventilation, partial liquid ventilation and inhaled nitric oxi- de.

Monitoring of alveolar acinus recruitment: oximetry arterial and pulse saturation measurement , PaCO 2, arterial pressure, computerized axial tomography CAT , dynamic CAT done during the recruitment maneuver. Conclusions: In spite of their mechanical origin, mechanical ventilation lesions occur due to changes in biochemical elements such as the surfactant, the action of inflammatory mediators, etc.

The lack of large casuistic that supports the success of maneuvers as regards healing and the duration of the benefits of the maneuvers especially in the immediate postoperative period , as well as those concerning survival and morbi-mortality leads us to state that, as yet, there is no evidence about the degree of success of such maneuvers.

There is an improvement in reported monitoring that leads, with certainty, to the frequent use of these strategies, with the pertinent safeguards that allow achieving the specified beneficial repercussions.
