Fig. 2From: Haemodynamic outcomes during piston-based mechanical CPR with or without active decompression in a porcine model of cardiac arrestDemonstrates a pressure curve (aortic pressure in this example) and our definitions of the different phases of the chest compression cycle. Chest compression cycle phases was determined based on aortic pressure curves. y-axis = pressure (mmHg), x-axis = timeBack to article page
