The ventilator adaptor has a first movable element with a first inlet and a second inlet, and a second movable element movably attached to the first movable element and with an outlet. The outlet has an inner diameter of 14.5-15.5 mm, preferably 15 mm, and the first inlet and the second inlet have an outer diameter of 14.5-15.5 mm, preferably 15 mm. The outlet is in fluid communication with the first inlet in a first position or with the second inlet in a second position by moving the second movable element relative to the first movable element thereby aligning the outlet with the first inlet or the second inlet. The outlet may be attached to an endotracheal tube in order to form a ventilation assembly. ## Claims ### Claim 1 A ventilator adaptor, comprising: a first movable element having a first inlet and a second inlet on an outer surface, wherein the first movable element has a concave inner surface opposite the outer surface; and a second movable element movably attached to the first movable element and having an outlet tube extending in an opposite direction from the first movable element, wherein the second movable element has an outer surface opposite the outlet tube matching the concave inner surface of the first movable element, wherein the inner surface of the first movable element includes circumferential grooves surrounding the first inlet and the second inlet, each groove configured to hold an o-ring in compression between the inner surface of the first movable element and the outer surface of the second movable element and separate the inner surface of the first movable element and the outer surface of the second movable element by a gap of 0.2-2 mm, wherein the first movable element has an integral annular inwardly directed radial lip that fits into an annular radial groove around the circumference of the second movable element, wherein the outlet tube has an inner diameter of 14.5-15.5 mm, wherein the first inlet and the second inlet have an outer diameter of 14.5-15.5 mm, and whereby the outlet tube is in fluid communication with the first inlet in a first position or is in fluid communication with the second inlet in a second position by moving the second movable element relative to the first movable element thereby aligning the outlet tube with the first inlet or the second inlet, and wherein the first movable element is rotatable relative to the second movable element to align the outlet tube with the first inlet in the first position or the second inlet in the second position. ### Claim 2 (depends on 1) The ventilator adaptor of claim 1, which, other than the first inlet, the second inlet, and the outlet tube, does not have an additional inlet or outlet. ### Claim 3 (depends on 1) The ventilator adaptor of claim 1, further comprising a third inlet on the first movable element. ### Claim 4 (depends on 1) The ventilator adaptor of claim 1, wherein no intermediary position of the outlet tube between the first position and the second position establishes fluid communication simultaneously among the first inlet, the second inlet, and the outlet tube. ### Claim 5 (depends on 1) The ventilator adaptor of claim 1, further comprising a cap configured to cover the first inlet, the second inlet, or both independently. ### Claim 6 (depends on 5) The ventilator adaptor of claim 5, wherein the cap comprises a tether attached to a crossbar connected to both the first inlet and the second inlet, wherein the cap is configured to independently cover the first inlet and the second inlet. ### Claim 7 (depends on 1) The ventilator adaptor of claim 1, further comprising a label, a notch, or a groove to indicate an alignment of the first movable element with respect to the second movable element in the first position or in the second position. ### Claim 8 (depends on 1) A ventilation assembly, comprising: the ventilator adaptor of claim 1 and an endotracheal tube removably attached to the outlet tube. ### Claim 9 (depends on 8) A method for switching between ventilator devices with the ventilation assembly of claim 8 while maintaining respiratory support through the endotracheal tube, the method comprising: providing respiratory support by fluidly connecting the endotracheal tube with a first ventilator device fluidly connected to the first inlet, wherein the outlet tube is in the first position; connecting a second ventilator device to the second inlet; moving the outlet tube from the first position to the second position thereby providing respiratory support by fluidly connecting the endotracheal tube with the second ventilator device; and disconnecting the first ventilator device from the first inlet. ### Claim 10 (depends on 9) The method of claim 9, wherein the first ventilator device is a mechanical ventilator, and the second ventilator device is a manual resuscitator device. ### Claim 11 (depends on 9) The method of claim 9, wherein the endotracheal tube is disposed within a patient, and a lung recruitment of the patient is maintained from before the moving to after the moving. ### Claim 12 (depends on 1) The ventilator adaptor of claim 1, wherein no collar is present around the circumference of the first or second movable element.
