“…To limit these harms it may be beneficial to expedite weaning from strict lung protective ventilation parameters to allow for lower sedation requirements. However, it is also possible that allowing patients to breathe spontaneously before they have adequately recovered from their critical illness may result in worsened injury or further impact patient hemodynamics [15][16][17]. While spontaneous breathing may be beneficial in less sick patients with improved ventilation/perfusion matching and more physiologic breathing [18], this may not be the case for sicker patients with potentially injurious pressure and volume subsequently leading to worsened lung injurywhat has been described as patient self-induced lung injury (P-SILI) [19][20][21][22][23].…”
