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.

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 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.

Compressions with a Lund University Cardiopulmonary Assist System (LUCAS) device, which enhances sternal recoil, were performed at a 100-per-minute rate, at a duty cycle of 50:50, and likely with an adequate force necessary to achieve a compression depth of 30% of the anteroposterior diameter of the thorax (known optimal compression depth for 19 ± 2-kg Landrace piglets used in this study based on one of their previous studies), after 8 minutes of untreated ventricular fibrillation.

x Dr Wang and colleagues [1] studied the physiological effects and quality of chest compressions during cardiopulmonary resuscitation (CPR) at sea level and high altitude. Thirty-eight participants were asked to perform continuous chest compression CPR (CCC-CPR) for 5 minutes at sea level and at high altitude. They quantified the quality of the chest compressions and measured the rescuers' blood oxygen saturation, systolic blood pressure, diastolic blood pressure, heart rate, and fatigue, as measured with the Borg score, after CCC-CPR compared with resting levels.

x Drowning continues to be a leading cause of accidental death worldwide. In case of drowning, duration of hypoxia is the critical outcome factor. Therefore, immediate good-quality cardiopulmonary resuscitation (CPR) at the scene, with early ventilations, is essential to increase the chances of survival and to reduce the neurologic damage of survivors [1,2]. Evidence indicates that in real life, quality of CPR, even when performed by staff with duty to assist, used to be poor [3–10]. In drowning events, the extreme physical conditions in which lifeguards have to perform CPR (sometimes after performing victim's water rescue), may result in even worse CPR quality [11].

A dog model was used with ventricular fibrillation (VF) of 20 minutes, reperfusion with brief cardiopulmonary bypass, controlled ventilation to 20 hours, and intensive care to 96 hours. A retrospective comparison was made of the results of one series, now called “group I” (n = 10)—which received CPR basic life support interposed from VF 10 to 15 minutes, and CPR advanced life support with epinephrine (without defibrillation) from VF 15 to 20 minutes—to the results of another series, now “control group II” (n = 10)—which received VF no flow (no CPR) for 20 minutes.

x I agree with your opinion that unsuccessful outcomes after successful CPR are in part due to impaired cerebral function caused by ischemic brain injury. Epinephrine is currently a suboptimal drug for CPR and needs to be evaluated further. The problem is how to reduce or avoid the adverse effect of epinephrine during and after CPR. If possible, we should do our best to search for a better therapeutic drug for cardiac arrest.

x Cardiac arrest is a major concern in health care, owing to its high incidence and mortality rates. Since the development of external cardiopulmonary resuscitation (CPR), there has been little advancement in nonpharmacologic therapies that have increased survival rates associated with cardiac arrest. Consequently, there has been much interest in the development of new techniques to improve the efficacy of CPR, particularly in the development of devices. Initially, many of the devices developed were not considered functional and failed to gain acceptance in the clinical setting.

x Manually-performed external chest compression during cardiopulmonary resuscitation (CPR) produces only a quarter to a third of the normal blood flow. The systolic and diastolic pressures generated by the standard manual technique, even if optimally performed are barely adequate to sustain life. Automatic resuscitators can provide chest compressions or ventilations during CPR. The device has many advantages to perform standard “American Heart Association” (AHA) CPR.

We call this unit the coronary perfusion index (CPI). True mean coronary perfusion pressure is CPI/60.

Bystanders initiated CPR for 579 patients (bystander CPR); for the remaining 718 patients, CPR was delayed until the arrival of EMTs (delayed CPR). Survival was significantly better (P < 0.05) in the bystander-CPR group (32%) than in the delayed-CPR group (22%).

x It is well known that prompt and good quality cardiopulmonary resuscitation (CPR) is fundamental for cardiac arrest victim survival. However, it has been demonstrated by us [1] and other authors [1-10] that the fears of lay rescuers negatively influence the willingness to perform CPR on a stranger. This could explain the lack of increase in the percentage of bystander CPR in the last few years. We have previously found that the main fears are the dread of not being capable, causing physical harm, facing legal consequences, and contracting an infectious disease.

Several points of interest were raised by this article. First, we found that the participants who were trained on cardiopulmonary resuscitation (CPR) within the previous year performed CC at a rate of approximately 120 per minute with the patient either on the floor or on a stretcher, whereas others performed CC with 100 per minute on both surfaces [1].

Thirty-one subjects trained in CPR recelved retention packets 3 and 6 months after CPR training. Sixteen subjects were tested for CPR retention at 7 months after initial training, and 15 at 12 months. Likelihood χ 2 was used to compare the 7- and 12-month groups. There were no differences between the 7- and 12-month groups, because CPR retention overall was poor.

x Rescuers that undergo acute ascent without acclimatization can experience acute mountain sickness. Although performing cardiopulmonary resuscitation (CPR) for a short period requires intensive effort at sea level, performing CPR at high altitude is even more exhausting and can endanger the rescuer. Therefore, we conducted a pilot study to compare the quality of resuscitation in health professionals at high altitude (3100 m) and that at sea level.
