    Ergometer Operation Manual Type er900L Configuration 7.3.5 RPM Control Sometimes, it may be necessary for the patient to discontinue pedaling for one reason or another. Normally, when the RPM value drops below the minimum value (30 RPM), this will lead to an abort of the load program since a defined load is no more present. Now it is possible to turn off RPM control for these special applications.

    Some of these parameters are code protected and should not be modified by the op- erator due to safety considerations. Notify your authorized dealer or the ergoline ser- vice department if you wish to alter any one of these protected parameters.

  • Page 44: Defining An Ergometry Program

    Defining an Ergometry Program The operator may select from 10 different ergometric programs when using the ergometrics er900L. Of these 10 programs, eight are fully programmable, one pro- gram offers automatic loading and one program is for pulse-steady-state training. Ergometric program definition is only possible when the ergometer is controlled internally, i.e.

    Ergometer Operation Manual Type er900L Configuration 7.4.1 Setup of Automatic Program 0 Automatic program 0 is for the fully automated testing of patients with unknown circula- tion condition, in particular, weak patients. The ergometer’s control computer uses this program to test the patient’s circulation response across two or three different but spe- cific load increments.

  • Page 46: Definition Of Programs 1-8

    Ergometer Operation Manual Type er900L Configuration 7.4.2 Definition of Programs 1-8 The operator has the choice of eight stress programs that are freely programmable to specific requirements on the ergometrics er900. In these eight programs, all control and alarm parameters are fully selectable. As with programs 0 and 9, the setup accom- plished with the monitor program represents a basic setup that can still be changed for any specific ergometry run at the beginning of that particular ergometry.

Systole = alarm parameter, when reached will cause program termination max. Diastole = alarm parameter, when reached will cause program termination Start Load = load value with which the system begins stressing the patient.

  • Page 48: Definition Of Program 9 For Pulse-Steady-State Training

    Ergometer Operation Manual Type er900L Configuration 7.4.3 Definition of Program 9 for Pulse-Steady-State Training Program 9 offers pulse-steady-state training capability. A continuously available heart rate input is prerequisite for this program. Heart rate input can be accomplished in various ways. You can attach an ear/finger clip, a pulse monitor (such as the Polar Pacer) or connect a QRS trigger output from an ECG device being used (see Annex E to this operator’s manual).
  • Page 49 Ergometer Operation Manual Type er900L Configuration The meaning of the various training parameters: max. Heartfreq. This is the pulse-steady-state limit for heart rate that is to be used in this training. When this limit is reached, the ergometer will take over complete load control to ensure that the patient’s heart rate remains stable at this level (by lowering and raising the load automatically).

  • Page 50: Structure Of Programs

    Die Programs 1-8 can be individually programmed for the testing of various patient groups such that at the push of a button the right program is at hand. Programs 1-4 have been pre-programmed with sample programs by ergoline prior to delivery. These programs are only exemplary and can certainly be changed.

Individual load increments are not programmable. The load- ing process is determined automatically by the ergometer during the ergometry pro- cess and is only dependent upon the circulation response of the patient.
