Oscillometric Measuring Method

For periods of up to 30 hours, TONOPORT V records the patient's blood pressure at selectable intervals and saves the results. There is a choice of three different measurement protocols.

The blood pressure is measured by the oscillometric method. The criteria for this method are the pressure pulsations superimposed with every systole on the air pressure in the cuff.

Using TONOPORT V with CASETM /

TONOPORT V can be operated in conjunction with CASETM (version 5.15 or later), with CardioSysTM (version 4.14 or later), or with the analysis program CardioSoft (version 4.14 or later) that is included with TONOPORT V. If the USB port is used, it is necessary to install the appropriate driver first (see “Software Installation” on page 22). With these systems, individual measurement protocols can be created and the stored data can be reviewed on-

If this is not ensured, the hydrostatic pressure of the liquid column in the blood vessels will lead to incorrect results. y When the patient is sitting or standing during measurements, the cuff is automatically at the correct level.

With V6.5 and subsequent versions, the patient ID used by the analysis program can be stored in TONOPORT V to allow the collected data to be downloaded without selecting the patient first (refer to the respective Operator Manuals; you will find the CardioSoft manual on the CardioSoft CD).

Compliance with the standard IEC 60601-1-1 must always be ensured. – TONOPORT V may be connected to CASETM, CardioSysTM or to a PC with the CardioSoft program. While connected to any of these devices, TONOPORT V must be disconnected from the patient. – Chemicals required for the maintenance of the equipment, for instance, must under all circumstances be prepared, stored, and kept at hand in their specific containers. Failure to observe this instruction may have severe consequences for the patient. – Liquids must not enter the equipment. Equipment into which liquids have entered must be inspected by a service technician before use. – Before cleaning, TONOPORT V must be disconnected from other equipment (CASETM, CardioSysTM, PC). – Dispose of the packaging material, observing the applicable waste-control regulations. Keep the packaging material out of children's reach.

Setup

Some Basic Facts on Battery Power

Insert Batteries

TONOPORT V is either powered by two rechargeable Nickel Metal Hydrid batteries (NiMH) or by two alkaline batteries. The device must be set to the power source used (see section "Insert Batteries" below). The device also contains a Lithium cell that powers the clock. The Lithium cell can only be replaced by a service technician.

Note Switch TONOPORT V off before inserting the batteries. To do so, slide the ON/OFF switch (10, Fig. 2-1) to the left while looking at the display. y Hold TONOPORT V as shown in Fig. 3-1 and slide
