The way forward: analyses based on raw, continuous data. It is technically absolutely feasible to collect it. Push manufacturers to release it without artificial barriers, put it in your procurement criteria, and make data accessible.

And for invasive arterial pressure: algorithms likely take the lowest value as diastolic, and intra-thoracic pressure bottoms out during chest recoil. Those short periods likely don't represent the whole diastolic period. Lower airway and central vessels share the same compartment.

The same is likely true for waveform capnography. The value shown is supposed to be end-tidal — but with multiple airflow reversals per real ventilation cycle, there's no way to know at which timepoint the device measured. A major systematic issue, to my knowledge never quantified.

Physiology-guided CPR: targeted interventions, aiming for ill defined goals? Not news, but it emerged clearer than ever in the session at #RESUS26. A thread on why we can't trust the numbers our devices show us during CPR — and what it would take to fix that. 🧵

Published already a few months ago now, but never shared - and highly relevant as there's a growing evidence base that measurement of asynchronous ventilation during ongoing chest compressions needs reproducible definitions and approaches.

Every decision is auditable: each excluded record is paired with the record it matched. So if you (or Reviewer 2 😉) want to check exactly what was removed, the table is ready. You also get downloadable outputs and a pre-filled, editable PRISMA flowchart.

Across five datasets from medicine, education & social welfare, it caught roughly 80% of all duplicates and cut deduplication time by a similar amount. It uses no fuzzy matching: a record is removed only when its normalized DOI and title match exactly.

A prespecified defibrillator-malfunction endpoint is half of the answer if nobody mandates how the device is checked. Of 8 DSED trials we tabulated replying to Schnaubelt et al., only 2 describe a post-use testing procedure, while almost all record malfunction in some way. doi.org/10.1016/j.re...

Evaluating for pneumothorax is the most accurate aspect within the eFAST protocol - and the most actionable finding in a pre-hospital setting.

What I'm personally taking for clinical practice: - Press the buttons sequentially, not simultaneously. - Check both devices after any dual defibrillator use: sometimes, damage was discovered during later cases. - Make sure to collect device-safety data Published in @resuscitation.bsky.social

#DSED is increasingly implemented for refractory VF, and dual cardioversion seems effective for elective cases too. Question I've discussed too often with colleagues - everyone had opinions, no one a well-founded answer - is simple: is this safe for the #defibrillators? doi.org/10.1016/j.re...

Graphical abstract titled "DSED (double sequential defibrillation) and dual cardioversion are promising interventions… but can they damage defibrillators?" — a scoping-review summary. Left: 5 published sources reported 8 lasting device damages and 4 temporary malfunctions; 24 regulatory adverse-event reports added 11 lasting damages and 16 temporary malfunctions. Right, under "Sequential vs. simultaneous": in published sources all damages followed simultaneous shocks, while in regulatory reports most were labelled DSED but the exact shock timing could not be determined. Bottom line: some damage was not detected until later testing or a subsequent case, so devices should be tested after dual defibrillator use. Citation: Purkarthofer et al., Resuscitation 2026.
