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.

x The addition of abdominal counterpulsation to standard cardiopulmonary resuscitation (AC-CPR) during ventricular fibrillation has been shown to improve cardiac output, oxygen uptake, and central arterial blood pressure in dogs. The present study was performed to determine the effect of AC-CPR on regional blood flow. Regional blood flow was measured with radioactively labeled microspheres during sinus rhythm and during alternate periods of AC-CPR and standard CPR (STD-CPR) in nine dogs anesthetized with pentobarbital.

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.

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 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 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 Takotsubo cardiomyopathy (TC)—ampullar cardiomyopathy—is a novel cardiac syndrome that has acute onset of chest pain, electrocardiographic change, and minimal elevation of cardiac enzymes resembling acute myocardial infarction without any evidence of myocardial ischemia or injury. Its characteristic image in angiography is a transient left ventricular (LV) apical ballooning having the appearance of takotsubo , Japanese for octopus trap [1-3]. We report here a rare case of a 69-year-old woman with type 2 diabetes mellitus (DM) who exhibited myocardial depression with the typical wall motion abnormality seen in TC during a period of sepsis.

x The author observes that an incremental approach to improving basic life support (BLS) has met with limited success. Rather than continuing to optimize each of the broadly different techniques for increasing forward blood flow, we should evaluate a combination of techniques. Because human providers would likely be unable to apply such a combination, the next generation in the chain of survival, after immediate manual BLS, should be a machine. As envisioned, this machine would incorporate optimized circumferential constriction, anteroposterior compression with forceful decompression, and partial airway obstruction into one system—a combination of combinations.
