Ostensibly written as an introduction to the use of the "grypotonograph," an apparatus for the oscillographic registration of blood pressure and pulse waves, this book turns out to be a thoroughgoing analysis of the theoretical concepts underlying the measurement of blood pressure, the comparison between direct and indirect methods, the "staircase curve" (pulse tracings obtained during inflation of the manometer cuff from levels below the diastolic to levels above the systolic arterial pressure) and many other interesting problems. Great emphasis is laid on the overpressure produced in the artery above the cuff as the result of artificial obstruction to the pulse wave in the compressed portion of the artery. The form of the individual pulse waves in the graphic record is made use of in determining systolic and diastolic pressures. Comparative data obtained through various methods of blood pressure estimation are critically discussed in the light of the physiology and
