x Recent studies evaluating interposed abdominal compression cardiopulmonary resuscitation (IAC-CPR) have demonstrated a significant increase in cardiac output, mean arterial pressure, and cerebral perfusion, as compared with standard CPR. A clinical evaluation of IAC-CPR effectiveness on resuscitation out-come has not been reported. A prospective randomized study comparing IAC-CRP with standard CPR for resuscitation of pre-hospital cardiopulmonary arrest was undertaken using the Milwaukee County Paramedic System.

x Despite the problems inherent in estimating blood flow from pressure, determination of systolic arterial pressure during cardiopulmonary resuscitation (CPR) is common and probably valuable as an indicator of potential systemic flow. The addition of interposed abdominal compression (IAC) to closed-chest CPR has been promoted because of its potential to increase systolic arterial pressure during CPR. Interposed abdominal compressions have also reportedly increased diastolic arterial-central venous pressure difference (DA-DCVP) and, thus, have the potential to increase coronary vascular flow.

x Perfusion of the cerebral cortex (rCCBF) during resuscitation from cardiac arrest was studied using 24 large dogs and three different resuscitation models. Conventional cardiopulmonary resuscitation (CPR) was compared with interposed abdominal compression CPR (IAC-CPR) and with IAC-CPR together with infusion of epinephrine. Conventional CPR produced a mean rCCBF of only 11% (0.057 ± 0.07 ml/min/g) normal perfusion (0.54 ± 0.14 ml/min/g). Even without epinephrine, IAC-CPR produced mean rCCBF equal to 51% (0.27 ± 0.17 ml/min/g) of normal.

x This study was undertaken to determine the effect of interposed abdominal compressions (IAC) during cardiopulmonary resuscitation (CPR) on gastric insufflation when the airway is not secured with an endotracheal tube. A canine model was used in which a common ventilation pressure was applied to separate cuffed esophageal and tracheal tubes. Gas entering the stomach was collected by a pre-placed gastrostomy tube leading to a bell spirometer. Gas entering the lungs was measured with a Wright Respirometer® in series with the endotracheal tube.

Abdominal counterpulsation in cardiopulmonary resuscitation: Animal models and theoretical considerations Charles F. Babbs

x Abdominal counterpulsation improves blood flow during other-wise standard CPR in animal models and in electronic models of the circulation. The method generates both central aortic and central venous pressure pulses. Success depends upon maximizing the former and minimizing the latter. Solution of a simple, first-order, differential equation may provide insight into proper technique. The equation suggests that the central arteriovenous pressure difference is maximized when pressure is applied directly over the abdominal aorta and when fluid loading is avoided.
Cardiac, thoracic, and abdominal pump mechanisms in cardiopulmonary resuscitation: Studies in an electrical model of the circulation Charles F. Babbs, J.Christopher Weaver, Sandra H. Ralston, Leslie A. Geddes

x To investigate alternative mechanisms generating artificial circulation during cardiopulmonary resuscitation (CPR), an electrical model of the circulation was developed. Heart and blood vessels were modeled as resistive-capacitive networks; pressures in the chest, abdomen, and vascular compartments as voltages; blood flow as electric current; blood inertia as inductance; and the cardiac and venous valves as diodes. External pressurization of thoracic and abdominal vessels, as would occur in CPR, was simulated by application of half-sinusoidal voltage pulses.

x Geddes et al [1] published a preliminary animal study introducing a new method of cardiopulmonary resuscitation (CPR) in which rescuers use only abdominal compressions (OAC) to resuscitate sudden ventricular fibrillation cardiac arrest, which they referred to as OAC-CPR. They reported that the idea of using abdominal compressions during CPR originated with Ralston et al [2] who studied the use of interposed abdominal compressions (IAC) with standard chest-compressions CPR (or IAC-CPR). They suggested that it was logical to explore the potential of using abdominal compressions without chest compressions because blood flow during IAC-CPR was found to be double that of standard chest-compressions CPR, therefore prompting them to conduct their study.

x Regarding the Ralston introduction of interposed Abdominal Compression (IAC) CPR, she did her work in my lab in 1980; the paper appeared in 1982 [1]. In all cases, the ventricles were fibriliating. The paper by Coletti et al [2] was published in the same year, but OAC was used to assist the failing beating dog heart. We agree, OAC is a safe and useful method of assisting the circulation as was shown in our paper by the increasing coronary perfusion when compared in the SAME animal using standard chest-compression CPR.
