Respiratory synchronisation<br />

• Modified RTX respirator* (Medivent, London, UK)<br />

• External respirator – no preparation required<br />

• Plastic cuirass, airtight seal, drive unit<br />

• Respiratory phases actively controlled by<br />

pressure change inside the cuirass:<br />

­ pressure: chest compression: expiration<br />

­ pressure: chest expansion: inspiration<br />

• Highly reproducible chest + diaphragm positions<br />

• ECG triggered mode: 1 full respiratory cycle per<br />

cardiac cycle.<br />
