Abstract: A method of applying total liquid ventilation to a patient according to a ventilation cycle including inspiration and expiration profiles, comprises supplying oxygenated liquid to the patient's lungs, withdrawing liquid from the patient's lungs, and controlling independently supply of oxygenated liquid to the patient's lungs and withdrawal of liquid from the patient's lungs. This supply and withdrawal independent control comprises producing a ventilation cycle having independently controlled inspiration and expiration profiles. To carry out the method, a total liquid ventilator system comprises an inspiration pump for supplying oxygenated liquid to the patient's lungs, and an expiration pump for withdrawing liquid from the patient's lungs. A ventilation cycle control comprises first and second pump controllers connected to the inspiration and expiration pumps, respectively, to produce a ventilation cycle having independently controlled inspiration and expiration profiles.

Abstract: A toy having a pivoting member such as a dump bucket or bed, with an automatic locking system on the pivoting member. An embodiment of the present invention provides toy having a chassis, a pivoting member pivotably and slideably mounted on the chassis, and a latch mechanism. The pivoting member pivots with respect to a pivot axis and slides in a direction radial to the pivot axis from a first position to a second position. The latch mechanism engages the chassis with the pivoting member in the first position and prevents the pivoting member from pivoting, and disengages the chassis from the pivoting member in the second position to allow the pivoting member to pivot.
