Adrenaline and return of spontaneous circulation during in-hospital cardiac arrest Open
We found a rapid and five-fold increase in the transition intensity from primary PEA to ROSC approximately one minute after adrenaline administration. Repeated doses in the absence of an initial response did not alone increase the transiti…

Realtime detection of spontaneous circulation in humans during cardiopulmonary resuscitation using a continuous hands-free carotid Doppler: a pilot study Open
Real-time detection of blood flow in the carotid artery with hands-free Doppler ultrasound during CPR is safe and feasible, although the fastening patch and host unit need optimization. The RescueDoppler system detects spontaneous circulat…

A deep learning model for QRS delineation in organized rhythms during in-hospital cardiac arrest Open
A precise delineator like this could support clinical practice by quantifying QRS features to enhance diagnostic accuracy and optimize treatment strategies.

Re‐arrest immediately after return of spontaneous circulation: A retrospective observational study of in‐hospital cardiac arrest Open
Background Patients who achieve return of spontaneous circulation (ROSC) after in‐hospital cardiac arrest (IHCA) may re‐arrest. This phenomenon has not been sufficiently investigated. The aim of this study was to examine the immediate (1‐m…

Machine learning model to predict evolution of pulseless electrical activity during in-hospital cardiac arrest Open
Information hidden in the waveforms of the ECG and TTI signals, along with QRS complex features, can predict the progression of PEA. Automated methods as the one proposed in this study, could contribute to assist in the targeted treatment …

Non-shockable rhythms: A parametric model for the immediate probability of return of spontaneous circulation Open
The immediate probability of ROSC develops differently in PEA and asystole depending on the preceding rhythm and the duration of the resuscitation attempt. This knowledge may aid simple bedside prognostication and electronic resuscitation …

Heart rate and QRS duration as biomarkers predict the immediate outcome from pulseless electrical activity Open
HR and QRSd convey information of the immediateoutcome during resuscitation from PEA. These universally available and promising biomarkers may guide the emergency team in tailoring individual treatment.

Automated algorithm for QRS detection during pulseless electrical activity in cardiac arrest patients Open
Pulseless electrical activity (PEA) is one of the most common rhythms during a cardiac arrest (CA), and it consists in lack of palpable pulse in presence of electrical activity in the heart.The main treatment for a CA is the cardiopulmonar…

Pulseless electrical activity in in-hospital cardiac arrest – A crossroad for decisions Open
PEA is a crossroad in which the subsequent course is determined. The four distinct presentations of PEA behave differently on important characteristics. A transition to PEA during resuscitation should encourage the resuscitation team to co…
