When pressure rises in retrieval medicine, technical skill alone is not enough. Shared mental models, rally points, focused attention, closed-loop communication and well-designed cognitive aids help teams stay coordinated as clinicians move from flow towards cognitive overload, task fixation or freezing.

Prehospital, emergency and palliative-care teams get a practical framework for family-witnessed resuscitation, death at scene and communication after unsuccessful treatment. Non-abandonment, support for children, family presence, humane death notification and brief team debriefing are treated as active components of emergency care.

Prehospital, palliative-care and human-factors teams get a framework for care when resuscitation or acute treatment is no longer producing expected benefit. The episode keeps comfort, dignity, family presence, EASE communication and ENOUGH decision support within active emergency care.

Prehospital, emergency and trauma teams get a damage-control framework for exsanguinating injury. Haemorrhage control, rapid vascular access, blood-product resuscitation and movement towards operative source control take priority, while airway and obstructive causes of shock are managed without allowing avoidable scene delay.

Prehospital, trauma and critical-care teams get a specialist acute topic around ECMO after injury. It separates VV respiratory support from VA support for traumatic cardiogenic shock, while emphasising haemorrhage control, focused echocardiography, cannulation planning and evolving thrombosis risk.

Refractory VF is not just a cue for another shock or another drug. CPR fraction, peri-shock pauses, pad position, vector change, dual sequential defibrillation and post-ROSC hypotension all need protocolised practice before the arrest happens.

Persistent ventricular fibrillation after three shocks is a practical trigger, not just a pharmacology problem. The HEMS debrief focuses on DSED, vector change, pad position and training so shock strategy does not add pauses or confusion during cardiac arrest.

Traumatic cardiac arrest after a stab wound or major chest trauma needs more than one thoracotomy rule. This is the more specialist arrest listen, but it is sharp on tamponade versus exsanguination, how rhythm and witnessed physiology judge viability, and when ultrasound helps or delays chest opening.

Best saved for after the ward-arrest episode, this one helps when VF keeps returning or will not terminate. It separates recurrent from refractory ventricular fibrillation, reminds you to check truly lateral pad placement, and keeps the focus on compression fraction, ventilation, early intraosseous access, and ECPR or cath lab thinking.

Action beats gadgets in this cardiac arrest debrief. The episode keeps the focus on high-quality manual CPR, capnography, pad position, and defibrillation vector, while reminding prehospital teams not to overestimate mechanical CPR or ventilation devices when the basics have not been optimised.
