B30 Patient Monitor
2-32
Direct current for leads-off detection
through a reference electrode:
<120 nA
The normalized respiration sensing current between RA (R) and LL (F)
or RA (R) and LA (L) or LA (L) and LL (L):
<5.0 µA
Frequency of respiration sensing current: 31.25 kHz
Minimizing the effects of the line isolation monitor transients:
Crystal controlled oscillator used as the operating frequency source of the patient isolation power
supply.
The average time and time range ( ) to alarm (VFib or VTachy) for tachycardia waveform
are as follows (IEC60601-2-27 6.8.2.bb.6):
Figure 101 B1 halved amplitude:
9.9 s (8.4 to 11.5 s)
Figure 101 B1 normal amplitude: 7.1 s (5.8 to 8.2 s)
Figure 101 B1 doubled amplitude: 4.4 s (4.2 to 4.6 s)
Figure 101 B2 halved amplitude: 7.0 s (6.1 to 7.5 s)
Figure 101 B2 normal amplitude: 5.8 s (4.5 to 7.4 s)
Figure 101 B2 doubled amplitude: 6.1 s (5.1 to 7.0 s)
A clinician should always confirm the rhythm from the ECG waveform.
Direct cardiac application
The display area reserved for the ECG measurement in the screen may not be adequate for displaying
the complete ECG amplitude when measuring ECG direct from the surface of the heart. Clipping of the
signal can be reduced by adjusting the size of the signal on the screen (for example, from the default 1.0
to 0.2) in the ECG menu.
Impedance respiration
Respiration range: 4 to 120 resp/min
Accuracy: ± 5% or ± 5 resp/min, whichever is greater
The conducted RF immunity of the respiration measurement has been tested with 1 Vrms. The radiated
RF immunity of the respiration measurement has been tested with 1 V/m. The impedance respiration
measurement technology has been optimized so that the measurement is not sensitive to electrosurgery
equipment which is commonly used in the intended environment for the impedance respiration
measurement.
NOTE: Impedance respiration measurement is intended for patients ages three years
and up.
Invasive blood pressure
1
(E-PSMP module only)
Measurement range: -40 to 320 mmHg (-5.3 to 42.6 kPa)
Measurement accuracy: ±5 % or ±2 mmHg
Pulse rate:
Measurement range: 30 to 250 bpm
Accuracy: ±5 % or ±5 bpm
Transducer sensitivity: 5 µV/V/mmHg
1 The isolation barrier capacitance in the module has been minimized to reduce the hazard of burns in the event of a
defect in the ESU return electrode connection.
