ARRHYTHMIA PATIENTS: The Digital Vital Signs Device is designed to operate
in the presence of cardiac arrhythmias. However, the pulse rate meter may be
adversely affected in some cases.
Caution
BLOOD PRESSURE MEASUREMENT
• Do not allow the blood pressure cuff or hose to come into contact with
fluids. If this occurs, See “Cleaning“ of the devices’ Operations Manual
for drying instructions.
• Check the hose and cuff frequently for signs of damage or debris. An
obstruction in the hose may interfere with inflation and deflation, resulting
in inaccurate readings.
• To obtain accurate blood pressure readings, keep the limb and cuff
motionless.
• The blood pressure cuff should be at the same level as the patient’s
heart. If you cannot place the NIBP cuff at this level, add 1.4 mmHg to the
measured pressure values for each 2 cm above the heart level, or subtract
1.4 mmHg for each 2 cm below heart level.
• Blood pressure measurements may not be accurate if the patient is
convulsive or experiencing tremors.
• Check for kinks in the blood pressure hose if the device reports a
measurement problem.
Caution
• Read instructions provided with the sensor to understand the best
application technique and all relevant safety information.
• Do not apply the sensor on the same limb as the NIBP cuff. During blood
pressure measurements, the perfusion is temporarily reduced, which can
result in inaccurate pulse oximetry readings.
• Elevated levels of carboxyhemoglobin or methemoglobin can result in
inaccurate pulse oximetry readings.
• Bright light can create problems with the pulse oximetry measurements,
resulting in inaccurate readings. If the sensor is in a place where it may be
exposed to bright light, cover it with opaque material.
• Pulse oximetry readings may be inaccurate in the presence of excessive
motion artifact or tremors.

DEVICE DESCRIPTION
IQvitals® + Digital Vital Signs Device
The IQvitals
®
and Digital Vital Signs Device contains a Main Board, an I-O Board, and a Processor Board. The Main Board contains signal acquisition and power management
circuitry. The I-O Board contains data port connectors. The Processor Board runs both signal analysis software to generate the patient’s physiological readings and user interface
software to display the patient’s readings and trend them over time. The IQvitals contains an SD card to store the patient’s readings and the device settings, while the Digital Vital
Signs Device uses on-board ash memory.
®
IQvitals
The IQvitals
PC
®
PC device contains a Main Board and an I-O Board, but no Processor Board. In this case, the signal analysis software runs as part of the IQmanager® software package
on the clinician’s workstation.
Both devices are powered from either an external, medical-grade mains supply or an internal, rechargeable lithium-ion battery.
Both devices can connect to select digital scales.
Both devices are available with or without the SpO2 function.
A thermal printer purchased from Midmark, can be connected to the Digital Vital Signs Device device, but does not connect to the IQvitalsPC device.
GENERAL TROUBLESHOOTING NOTES
As a general rule, it is good idea to power-cycle the device to see if a problem persists. The device has numerous self-checks that will continue to trigger if the issue persists.
It is often necessary to isolate a problem to a particular component – the device, the power supply, a patient sensor, etc. It is a good idea to swap in a “known-working” component
to see where a problem lies.
Conrm that Midmark-approved SpO2 sensors and temperature probe covers are being used.
