2. Operating instructions
Countermeasures:
The doctor should draw the patient’s attention to the fact that the cuff must be worn on the upper
arm only and care must always be taken to ensure that neither the shoulder strap nor the air tube
can ever become wrapped around the neck. The air tube should therefore always be worn under the
outer clothing (even at night).
■
If you suspect that water may have entered the unit during cleaning or use of the equipment, the
device may no longer be used on the patient.
Inform your service engineer without delay or send it for testing.
■
The air tube may kink when inflated.
The doctor should explain to the patient that, particularly when sleeping, the equipment should be
positioned in such a way that the tube cannot be compressed. If the patient is not fully competent,
the equipment should be worn only under supervision.
■
In some patients petechiae, haemorrhages or subcutaneous haematomas may occur.
All patients must be told when putting on the cuff that if they experience pain they should switch off
the equipment and inform the doctor.
■
The doctor must be certain that, according to the health of the patient, the use of the device will not
damage blood circulation in the arm.
■
The Mobil-O-Graph
®
is not suitable for use at the same time as high-frequency surgical equipment.
■
The Mobil-O-Graph
®
fulfils the requirements of EMC standards; nevertheless, the Mobil-O-Graph
®
should not be exposed to strong electromagnetic fields, as outside the limits they may cause mal-
function.
■
The cuffs and the tube are made of electrically nonconductive material. They thus protect the device
from the effects of a defibrillator discharge.
■
During a defibrillator discharge the device must not be allowed to touch the patient. The device may
be damaged by such a discharge and give inaccurate measurements.
■
The device may not meet its performance specifications if stored or used outside the specified tem-
perature and humidity ranges (see section 3.5)
■
In the majority of all cases the device is able to function according to specifications in the presence
of common arrhythmias such as atrial or ventricular premature beats. In the condition of atrial fibril-
lation, the device may not be able to function to its specifications.
■
Caution: Substitution of a component different from that supplied might result in measurement error.
2.6 Important instructions for the patient
■
The beep signals a measurement. Keep still during the measurement, until the process is complete.
Let your arm hang loosely or, when sitting, let your lower arm rest on the table or on a support.
Avoid moving your hand during the measurement.
■
The Start key
triggers an additional measurement. Press this key only if instructed to do so
by your doctor (e.g. after taking medication, if you have chest pains or shortness of breath etc.).
■
The Event key
records the time of an event and triggers a measurement. Press this key only
if something important or unusual is happening.
■
The Day/Night key
should be pressed immediately before going to sleep and upon waking.
■
The ON/OFF key
permits the device to be switched on and off if a measurement is not required
at the set time. To switch off, press the key for longer than 2 seconds.
■
A measurement can be interrupted at any time by pressing any of the keys. This deflates the cuff.
Warnings:
■
The cuff may only be worn on the upper arm and in every case you should ensure that neither the
shoulder strap nor the air tube can ever become wrapped around your neck. The air tube should
therefore always be worn under the outer clothing (even at night).
■
Take care to ensure that the tube of the cuff cannot be kinked or compressed, particularly while
sleeping.
■
If the measurement causes you pain, switch off the device, take off the cuff and inform your doctor.
■
The blood pressure monitor must not come into contact with liquids. Do not wear the equipment in
the shower!
If, for example, water has entered the device, it may no longer be used. Switch off the device and
take out the batteries.
■
Serious malfunctions are indicated by a continuous beep. If a continuous beep sounds, switch off
the device, take off the cuff and inform your doctor.
■
The cuff connection (air connector) must always engage with an audible click. Otherwise there will
be a leaky connection between the Mobil-O-Graph
®
and the tube that will produce incorrect meas-
urements.
