NBP Safety Information
6-20 EarlyVue VS30 Instructions for Use
To recalculate NBP values and manually add them to the patient record
1 Take the NBP measurement normally and make a note of the systolic and diastolic
values.
2 Recalculate the systolic and diastolic values according to the table above.
3 If a mean arterial pressure (MAP) measurement value is required, use the recalculated
systolic and diastolic values to calculate a new mean using your facility’s standard
formula.
4 Touch the NBP pane on the main screen.
The NBP menu opens.
5 Touch the NBP Source menu and select Manual Input.
6 Enter the recalculated values in the Input Systolic Measurement field, the Input
Diastolic Measurement field, and—if required—the Input Mean Measurement field.
The manually entered values are saved when you save the patient record.
NBP Safety Information
WARNING
• Do not compress the NBP hose or restrict the pressure. A compressed or kinked hose may cause
the cuff to over-inflate and result in patient injury, patient discomfort, or inaccurate readings.
• Select the correct patient type for your patient. Do not apply the higher adult inflation limits and
measurement duration to neonatal patients. Over-inflating the cuff may cause patient injury,
patient discomfort or inaccurate readings.
• Do not measure NBP on patients with wounds, sickle-cell disease, or any condition where skin
damage has occurred or is expected to occur.
• Continual NBP measurements can cause injury to the patient being monitored. Weigh the
advantages of frequent measurement and/or use of STAT mode against the risk of injury. Use
clinical judgment to decide whether to perform frequent unattended blood pressure
measurements on patients with severe blood clotting disorders because of the risk of hematoma
in the limb fitted with the cuff.
• In some cases, rapid, prolonged cycling of an NBP cuff has been associated with any or all of the
following: ischemia, purpura, or neuropathy. Apply the cuff according to the directions and check
the cuff site and cuffed extremity regularly when blood pressure is measured at frequent
intervals or over extended periods of time.
• Check the patient’s limb to assure that circulation is not constricted. Constriction of circulation is
indicated by discoloration of the extremity. Check the limb at regular intervals based on the
circumstances of the specific situation.
• Do not place the cuff on any extremity where circulation is compromised or has the potential to
be compromised, including extremities being used for intravenous infusion, intravascular access
or therapy, or when an arterio-venous (A-V) shunt is present.
• Do not apply the blood pressure cuff to the same extremity as the one to which an SpO
2
sensor is
attached because the cuff inflation disrupts SpO
2
monitoring and leads to nuisance alarms.
