measurements in neonates. Also it is not suitable for use in intensive-care medicine.
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 CASE™ / CS
The blood pressure cuff is wrapped around the upper arm
TONOPORT V can be operated in conjunction with CASE™ (version 5.15 or later) or with the analysis program CS (version 4.14 or later) that is included

instances where there is any element of doubt concerning the safety of connected equipment, the user must contact the manufacturers concerned or other informed experts as to whether there is any possible danger to the patient, the operator, or the environment as a result of the proposed combination of equipment. Compliance with the standard IEC 60601-1-1 must always be ensured. – TONOPORT V may be connected to CASE™ or to a PC with the CS 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. – The equipment has no protection against the ingress of liquids. 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 (CASE™, 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 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. The capacity of two fully charged or new batteries is sufficient for a minimum of 30 hours of operation or for 200 measurements. The capacity of rechargeable batteries decreases with age. If the capacity of fully charged batteries is considerably less than 24 hours, the batteries must be replaced.

Application
Applying the Cuff Warning Risk to persons - Disconnect TONOPORT V from other equipment (CASE™, PC) before connecting it to the patient. y Always insert two fully charged NiMH batteries or two new alkaline batteries, before starting a measurement. y Check that the memory has been cleared (see “Clear the Memory” on page 15). y Select the appropriate cuff size (see cuff label). When the cuff is too small the BP values will be overrated, Fig. 4-1 Applying the cuff
when it is too big, the measured values will be too low. Caution Incorrect measurements - – Use only the cuffs listed in chapter 10 "Order Information". – Replace cuffs on a regular basis. Damaged Velcro fasteners may cause incorrect readings.

y Place the cuff on that arm of the patient that is used less frequently during normal daily activities. On adults it should be placed about 2 fingers' breadth above the bend of the elbow; on children, a little closer. Bending the arm must not change the cuff level.

For the first measurement, the cuff is inflated to a pressure of 160 mmHg (initial pressure). For subsequent measurements, the device inflates the cuff to a pressure which is 15 mmHg above the systolic value of the previous measurement (minimum inflation pressure: 120 mmHg).

After error codes E02 and E08, the device enters the powersave mode to prevent over-discharging of the rechargeable batteries. This mode can only be terminated by turning the device off and on again.
