UTILIZATION OF HAND-HELD PROGRAMMABLE CALCULATORS FOR RAPID BEDSIDE COMPUTATION OF PHYSIOLOGIC-PHARMACOLOGIC VARIABLES AND PROGNOSTIC INDICES DURING MECHANICAL CIRCULATORY SUPPORT.

This study describes five programs that may be used on compact, low-cost programmable calculators with adequate memory and sufficient numbers of program steps to compute cardiorespiratory variables. These short programs are especially useful in the operating room and at the bedside.

Intra-aortic balloon pumping: theory and practice. Experience with 325 patients.

Intra-aortic balloon pumping to support the failing circulation is now an accepted therapeutic modality. The device is simple. Insertion can be accomplished rapidly and efficiently in emergency rooms, coronary care units, cardiac catheterization suites and operating rooms, preoperatively, intraoperatively and postoperatively.

Molecular, microscopic, microstructural and mechanical methods of analyzing pseudoneointimal linings within partial artificial hearts in man and the calf.

Ex vivo molecular, microscopic (cellular), microstructural and mechanical methods have been utilized to evaluate biologic, blood-interfacing linings (pseudoneointimal) formed on textured, fibril-flocked pumping surfaces within abdominal left ventricular assist devices (ALVADs) on partial artificial hearts. Thus far, seventeen human and twenty bovine pseudoneointimal linings (1--28 day pumping durations) have been evaluated by these methods. The results indicate that pseudoneointima begins developing within 24 hours after contact of the pumping surface with blood and is well developed at five days.

Nitrogen retention of young men who consumed selection patterns of essential amino acids at a constant nitrogen intake.

Six patterns of essential amino acids were devised to represent different sources or combinations of protein based on a daily intake of 6.0 g of nitrogen from these sources. In each diet, cereals furnished 70% and a specially designed amino acid mixture 30% of the total nitrogen.

Effect on nitrogen retention by adults of different proportions of indispensable amino acids in isonitrogenous cereal-based based diets.

Nitrogen retention of adults who consumed diets in which cereals furnished 6.0 g N and 0.9 g of lysine was improved by increasing lysine to 1.

Lysine and tryptophan in cereal-based diets for adult human subjects.

A basic diet containing rice, wheat, and corn that furnished 6.0 g of nitrogen per day was consumed by health young adults. Two levels of lysine, 900 and 1800 mg, and three of tryptophan, 260, 390, and 520 mg, were tested.

Mechanical random access of blood bank records.

A filing system of cumulative patient record cards is described for use by large or active blood banks. Cards are retrieved for review of patient identification, past transfusion history, and legally necessary documentation of test results. Information on the cards is handwritten (as is required in most blood banks) only once, reducing transcription error.
