6 Deﬁbrillator/Transcutaneous Pacer Analyzers

Specications

Defibrillator Analyzer

Energy output measurement Compatible defibrillator waveshapes: Lown, Edmark, trapezoidal, dc bi-phasic, and ac pulsed bi-phasic

Autoranged measurement 0.1 J to 600 J

Accuracy 0.1 J to 360 J: ± 1 % of reading +0.1 J

360 J to 600 J: ± 1 % of reading +0.1 J, typical

Note: For pulsed bi-phasic defibrillator, specified accuracy is ± (1.5 % of reading + 0.3 J) on both ranges

Load resistance

Resistence: 50 Ω

Accuracy 1 %, non-inductive (< 2 μH)

Charge time measurement Range: 0.1 s to 100 s

Accuracy: ± 0.05 s, typical

Synchronization test

(cardioversion)

Delay time measurement

• Timing window: ECG R-wave peak to the defib pulse peak

• Range: -120 ms to 380 ms; measures timing from 120 ms prior to the R-wave peak to up to 380 ms

following the R-wave peak

Automated defibrillator test ECG waves

• Normal sinus: 10 BPM to 300 BPM in 1 BPM steps

• Ventricular fibrilation: Coarse and fine

• Monomorphic ventricular tachycardia: 120 BPM to 300 BPM in 1 BPM steps

• Polymorphic ventricular tachycardia: 5 types

• Asystole
