This study was designed to observe the effect of movement on ill, injured, or shocked animals. Lightly-anesthetized dogs were subjected to hemorrhagic shock. Ambulance transport was simulated by shaking, jolting, and rocking a table in three axes as well as lifting and dropping it. Accelerometer readings compared well with previously reported readings in ambulances. Simulated transport caused a rise in blood pressure and cardiac output in five of the six dogs, with no change in heart rate or right atrial pressure. A 15° head-up tilt caused a marked fall in blood pressure and cardiac output in two of the six dogs, leading to asystole in one. This could be related to diminished venous return from the lower body. Intermittent positive pressure ventilation had no protective action.
