ZOLL R Series
The ZOLL R Series is a hospital defibrillator and monitor used on crash carts and for in-hospital transport, offering manual and AED defibrillation, transcutaneous pacing and optional SpO2, NIBP and EtCO2. It uses ZOLL's rectilinear biphasic waveform up to 200 J and is known for its Code Readiness self-check and Real CPR Help feedback through OneStep electrodes.

Safety
Safety warnings from the record.
- For children under 8 years or under 25 kg, use ZOLL paediatric defibrillation electrodes, but do not delay therapy to establish exact age or weight. Source
- Prolonged pacing over 30 minutes, especially in neonates, can cause burns; inspect the skin under the electrodes periodically. Source
- In manual mode a charge is internally dumped after 60 seconds, and changing energy during charge also discharges it internally. Source
- Bedside or central monitors may show erratic ECG while the R Series is pacing, because pacer pulses overload their inputs; monitor ECG on the R Series during pacing. Source
- Active electrosurgical equipment can cause CHECK PADS messages; check it is off when troubleshooting pad faults. Source
- Do not place the unit in service if the Code Readiness indicator shows a red X, and do not touch connected paddles, electrodes or the OneStep connector while a readiness test is running. Source
