Assessment of the Von Recklinghausen oscillotonometer.
The Von Recklinghausen Scala Alternans Altera oscillotonometer was assessed in order to establish whether any of the disputed points over its use made a significant difference to the readings obtained. Inversion of a new cuff gave significantly higher systolic readings, but a worn cuff gave consistent results whatever its position. Measurements of systolic and diastolic pressures were not significantly affected by the use of the sustained leak lever provided the leak was small. Maintenance and cleaning of the instrument are essential for its proper working.
