ECG, make certain that the alarms are enabled, and then lower the HR upper
alarm limit setting below its current value. Verify that "HR < [upper limit]"
annunciates as a medium grade alarm. Press the ALARM SILENCE key, and
then return the HR upper alarm limit to its previous value. Verify that the alarm
is no longer active, and that ECG monitoring continues normally. Alternatively,
disconnect the RA or LL electrode. Verify that "HR lead off" annunciates as a
low grade alarm. Press ALARM SILENCE and reconnect the electrode. Verify
that the alarm ceases and that the ECG waveform and HR parameter return.
The ECG and Heart Rate Monitoring settings and specifications for the
Nightingale PPM3 may be found in the PPM3 Monitor Settings and Technical
Data chapters. Procedures for changing configuration settings, such as sourcing
pulse rate (PR) from SpO

while still displaying an ECG waveform, enabling a
HR/PR tone, displaying multiple ECG waveforms, or adjusting alarm limits, may
be found in the Working With Menus chapter.
WARNING – Conductive parts of the ECG patient cables, electrodes,
and associated connections of type CF applied parts, including the
neutral conductor of the patient cable and electrode should not come
into contact with other conductive parts including earth ground.
WARNING – Read safety instructions provided with a defibrillator.
The PPM3 is designed to withstand defibrillation and will recover
within 5 seconds, per IEC 60601-1. Only use accessories approved
by Zoe Medical for use with the Nightingale PPM3.
WARNING – Operating the Nightingale PPM3 with HR/PR limit alarms
disabled means that no low or high HR/PR alarm conditions will
produce alarm notifications. Use this feature with extreme caution.
Patients must be closely observed if HR/PR limit alarms are disabled.
WARNING – Care should be taken to ensure that the total patient-
applied current across all patient-connected equipment is less than
10 microamperes (uA). The PPM3 applies approximately 2½ uA.
CAUTION – Line isolation monitor transients may resemble actual cardiac
waveforms and thus inhibit heart rate alarms. To avoid the risk of this
happening, follow the directions for proper electrode placement, and keep
the ECG lead wires away from sources of line noise.
