LIFEPAK 15 Monitor/Defibrillator Operating Instructions
•
There may be some difference between readings taken manually and readings from the NIBP
monitor due to the differing sensitivity of the two methods. The NIBP monitor meets the
ANSI/SP10 AAMI standard that requires a mean difference of
±
5 mmHg, with a standard
deviation no greater than 8 mmHg, compared to auscultatory readings.
•
When using the NIBP monitor during defibrillation, the NIBP monitor is not available when the
defibrillator is being charged. Upon shock, the monitor resets and dashes (– – –) appear in
place of pressure readings. After defibrillation, you can resume blood pressure measurement
according to NIBP Monitoring Procedure (on page 82).
•
If the blood pressure cuff fails to deflate for any reason or causes undue discomfort to the
patient, remove the cuff from the arm or disconnect the tubing from the defibrillator.
•
If the patient has been active, optimal resting measurements will be obtained if you wait five
minutes before taking a blood pressure measurement.
Cuff Selection
The use of properly designed and sized cuffs is essential for the accurate measurement of blood
pressure. The cuff must fit snugly around the extremity to occlude the artery. For a list of BP
cuffs that are intended for use with the LIFEPAK 15 monitor/defibrillator, see the
LIFEPAK 15 Monitor/Defibrillator Accessories Catalog at www.physio-control.com.
NIBP Monitoring Procedure
The NIBP monitor inflates an occluding cuff and determines systolic and diastolic pressures,
mean arterial pressure (MAP), and pulse rate. Pressure measurements are reported in mmHg
and pulse rate in beats per minute (bpm).
Both single-measurement and specified-interval (timer-controlled) methods of blood pressure
reading are available.
The NIBP monitor draws power from the defibrillator. When the defibrillator is turned on, the
NIBP monitor conducts a self-test that takes approximately three seconds.
IMPORTANT! The LIFEPAK 15 monitor NIBP port and tubing are not compatible or
interchangeable with the NIBP tubing that is used with other LIFEPAK monitor/defibrillators.
Changing the Initial Inflation Pressure
The initial cuff pressure should be set approximately 30 mmHg higher than the patient’s
anticipated systolic pressure. The factory default initial inflation pressure for the first
measurement is 160 mmHg. For pediatric patients, the initial cuff pressure may need to be
lowered. Initial inflation settings are 80, 100, 120, 140, 160, or 180 mmHg. For infants, the
recommended initial cuff pressure is 120 mmHg.
Caution should be taken not to lower the initial pressure below the adult patient’s systolic
measurement. Doing so may cause the cuff to reinflate and cause patient discomfort. For
subsequent measurements, the monitor inflates approximately 30 mmHg higher than the
previously determined systolic pressure.
