Question: Abstract: Considerable effort has been expended in recent years by a number of laboratories to improve methods of cardiopulmonary resuscitation. This article briefly summarizes 5 years of investigation by our group on hemodynamic support during external cardiac massage. In most studies, long-term canine preparations were used, and implanted transducers allowed precise hemodynamic measurements. Although cardiac output was depressed with all CPR methods, manual chest compressions of high velocity, moderate force, and brief duration at a rate of 120/min seemed to optimize systemic and coronary blood flow. This method was termed high-impulse CPR. High-impulse techniques now have been applied extensively in the clinical setting, and preliminary observations also support their efficacy in man. Based on this experience, it is suggested that the American Heart Association guidelines be changed to recommend a manual chest compression rate of 120/min during closed-chest cardiac massage.

Answer: The influence of manual chest compression rate on hemodynamic support during cardiac arrest: high-impulse cardiopulmonary resuscitation.

Question: Abstract: To summarize the results: Bilirubin removal by hemoperfusion was successfully performed for the first time on a premature infant. The hemoperfusion caused no adverse effects on the clinical state of the infant. The bilirubin removed in 90 min--13 mg--indicates the existence of a large extravascular pool. Hemoperfusion is suggested for bilirubin removal from newborn babies, reducing the need for blood exchange with bank blood.

Answer: Bilirubin removal from a jaundiced premature infant by resin hemoperfusion.

Question: Abstract: Using a series of graded destabilizing forces, we have developed a simple quantitative test of the postural response: the Postural Stress Test (PST). Suitable for widespread testing of elderly subjects, the test evaluates the subject's ability to avoid a fall as well as the appropriateness of the response. We have determined that by comparison with young subjects, the elderly controls have compromised although functionally effective balance. On the other hand, the balance response was severely compromised in half of the individuals with a history of falls. Experience with the Postural Stress Test suggests it will predict those elderly individuals with a tendency to fall as well as provide a simple mechanism for studying the balance response in the elderly.

Answer:
Stressing the postural response. A quantitative method for testing balance.
