Operator manual Corival This is the short operator manual for the Lode Corival Ergometer, which describes the basic actions for starting up your ergometer. For a complete description, we refer to our User Guide. Intended Use A Lode ergometer is a diagnostic tool intended to be used as a stress test device in a medical environment. The main goal of the use of a Lode ergometer is to create reproducible stress tests.
Operator manual Corival Caution: Not suitable for use in the presence of flammable anaesthetics. Note: The voltage selector (115/230VAC) is inside the ergometer. The main unit panel has to be unscrewed. Voltage selection should be done by a technician! Possible hazards Using the Corival according to intended use, contra indications, maintenance, precaution and common sense stated above may not eliminate all hazards.

To stop the recovery phase press the ESC button to go back to the PROTOCOL menu.
Operator manual C Corival Heart rate option 928924 C.1 Connecting the Heart rate system (option 928924) To install a heart rate option purchased afterwards, follow the instructions given in the user guide supplied with the ergometer. Installation of the Heart rate option itself has to be done by service personnel only. C.2 Using the Heart rate option The heart rate option is automatically recognized by the ergometer.
Operator manual D Corival Blood pressure option 928817, -818, 820 With option 928817, -818, 820 it is possible to perform stand alone or external controlled blood pressure measurements. After installation the BP module is recognized automatically at start up of the ergometer, indicated by the following screen for a few seconds: LODE ERGOMETER TBD D.1 Using the BP system Caution: Carefully read the instructions in Appendix D.2 Patient Hook-up before continuing.
Operator manual Corival mm Hg below the last measured DIASTOLIC pressure. The used deflate rate is approximately 4 mm Hg/heartbeat. A list of most occurring warnings and errors is given in D.3 Abort codes BP system. The built-in BP module offers, in case of malfunction or poor performance, the possibility to make error codes visible. See for more information the user guide supplied with this ergometer. Caution: The interpretation of the error codes should be done only by experts.
Operator manual Corival Fig 3: Cuff position Caution: Never place the cuff so that the microphone is located in the elbow. Pull the cuff so tight, that it neither moves nor ties off the arm of the patient. By fasten the cuff too tight or too loose, error measurements are caused. Wrap the end of the cuff around the upper arm and close the Velcro fastening (Fig 4: Mounting the cuff). Fig 4: Mounting the cuff Ensure that the air hose from the monitor to the cuff is not compressed, crimped or damaged.
Operator manual Corival The intervals of the measurements should not be too short. Intervals of 2 minutes and more result in long pauses between the stenoses, so that venous congestion and artiospasm can be avoided. D.3 Prior.

Installation of the BP module itself has to be done by service personnel only.
Operator manual E Corival SpO2 option 928840 With option 928840 your Corival is able to perform stand alone or external controlled measurement of functional oxygen saturation of arterial hemoglobin (%SpO2) and pulse rate (BPM) for adult and pediatric test subjects. Keep in mind the fact that SpO2 measurements during arm exercise is not possible due to movement artifacts. Do not attach the pulse oximeter to the same limb as the Cuff of the blood pressure monitor or any other blood flow restrictor.

Operator manual F Corival 0 Watt Start-up System 906805 With option 906805 your Corival is able to start the Corival without load (0 watt) at a preset pedal speed (rpm). You can choose any pedal speed between 30 and 80 rpm. The number of revolutions is increased from 0 to the required rpm by means of a motor drive. With this option there is no energy-loss due to the start-up phase. This option has to be built-in in the Corival while manufacturing and cannot be added later on. F.
