Filter by:In order to monitor and improve cardiopulmonary resuscitation(CPR) quality, there is need for tools that provide real time feedback to responders. The use of invasive arterial pressure monitoring and end tidal carbon dioxide (ETCO2) as quality measures of CPR. Invasive pressure measurements are timeconsuming and cumbersome in resuscitation situations, and are very rarely practical. ETCO2 measurements require presence of a capnometer with an advanced airway. High quality chest compression will result inETCO2 between 2-2.5KPa. A rapid increase in ETCO2 on waveform capnography may enable ROSC to be detected while continuing chest compression and can be used as a tool to withhold the next dose of bolus adrenaline injection. Pulse oximetry, which noninvasively detects the blood flow of peripheral tissue, has achieved widespread clinical use. It was noticed that the pulse waveform frequency can reflect the rate and interruption time of chest compression(CC) during cardiopulmonary resuscitation(CPR). The perfusion index (PI) is obtained from pulse oximetry and is computed as the ratio of the pulsatile (alternating current) signal to the non-pulsatile (direct current) signal of infra-red light, expressed as a percentage;PI =ACIR/DCIR∗100% (i.e. AC = pulsatile component of the signal, DC = non-pulsatile component of the signal, IR = infrared light). PI shows the perfusion status of the tissue in the applied area for an instant and a certain time interval. The PI value ranges from 0.02% (very weak) to 20% (strong).Peripheral PI has been proposed for different clinical uses with some applications in critical patients. The purpose of this study is to evaluate the role of pulse-oximeter derived perfusion index for high quality CPR and as aprognostication tool of ROSC during in-hospital cardiac arrest in comparison to ETCO2 reading.
The goal of this randomized controlled trial is to compare prehospital ventilation strategies in out-of-hospital cardiac arrest. The intervention group is automatic ventilation and the control group is manual ventilation. The main questions it aims to answer are: 1. How does automatic ventilation affect OHCA patients' survival and prognosis comparing to manual ventilation. 2. What are the differences on resuscitation qualities between automatic ventilation and manual ventilation.
The objective of this study is to estimate the feasibility and safety of early weaning from ICU treatment in patients after cardiac arrest and an early (< 12 h) favourable EEG pattern (indicating no or mild postanoxic encephalopathy).
The goal of this study is to test the feasibility and acceptability of an informational website to reduce uncertainty, psychological distress, and caregiver burden among close family members of cardiac arrest patients. The investigators hypothesize that participants who receive access to the website will have lower rates of uncertainty, psychological distress, and caregiver burden at 3 months post-hospital discharge compared to participants who receive usual care.
The investigators propose a multicenter randomized controlled trial in South Korea and Taiwan to observe the clinical effects of REBOA on nontraumatic out-of-hospital-cardiac-arrest (OHCA) patients. While REBOA has been traditionally used in trauma for hemorrhage control, it has also shown promising results in nontraumatic cardiac arrests by rerouting circulation to increase perfusion in the coronary and brain.
This study evaluates patients suffering from traumatic cardiac arrest assessed by the Danish HEMS between 2016 and 2021. The primary outcome is 30-day survival; secondary outcomes are status at admission to the hospital and prehospital return of spontaneous circulation. Further, the prehospital critical care was identified and evaluated.
The objective is to evaluate the effectiveness of a Just in Time (JiT) video as compared to the AHA Heartsaver® Course and no training (control) in ability to correctly perform CPR. The secondary objective is to assess skill retention 3-9 months after the AHA Heartsaver course with and without JiT Video use. The goal of this work is to study the effectiveness of this new JiT video to improve objective knowledge- and performance-based measures of effective OHCA response, as well as subjective ratings of preparedness and likeliness to respond, compared to the standard AHA Heartsaver® CPR AED Training course.
This is a single-center, observational study. Patients after successful cardiopulmonary resuscitation (CPR) will be transferred to the emergency intensive care unit for further standardized management. After successful return of spontaneous circulation (ROSC) for 72h and hemodynamics remained stable for 24h, the post-resuscitated patients underwent functional magnetic resonance imaging (fMRI) examination. During the examination, the supervising physician accompanied the patient and monitored the patient's vital signs using a magnetic resonance monitoring system (Siemens Healthcare Prism, Germany). Patients who are on ventilators are mechanically ventilated using a magnetic ventilator (HAMILTON-MRI, USA). In additional to conventional sequences, fMRI is performed for diffusion-prepared pseudo-continuous arterial spin labeling (DP-pCASL) and blood oxygenation level dependent functional magnetic resonance imaging (BOLD-fMRI). These MRI sequences allow quantitative assessment of the patients' cerebral microcirculation, blood-brain barrier, and cerebral oxygenation status. Patients will be followed up for neurologic prognosis according to the Modified Rankin Scale (mRS) at 6 months after disease onset.
Out-of-hospital cardiac arrest (OHCA) has multiple etiologies. In the absence of ST-elevation myocardial infarction, percutaneous coronary intervention (PCI) is delayed. This study aims to determine the diagnostic accuracy of Coronary Calcium Score (CCS) and Coronary CT Angiogram (CCTA) to rule out a coronary artery disease (CAD) in the first days after an OHCA.
Management of cardiac arrest according to published guidelines has remained largely unchanged for a decade. Thames Valley Air Ambulance provide Critical Care Paramedic and Physician teams who respond to cardiac arrests and offer treatments beyond the scope of ambulance service clinicians. Following a review of practice and appraisal of evidence the investigators developed an additional algorithm for cases of adult medical cardiac arrest with refractory shockable rhythms. This adds to but does not replace the Advanced Life Support algorithm and includes: - Delivering shocks with the LUCAS mechanical CPR device running - After 5 shocks have been delivered placing new pads in the Anterior Posterior (AP) position - Delivering shocks using the TVAA Tempus Pro defibrillator rather than the Ambulance Service defibrillator. This bundle was based on recommendations from ILCOR and the Resus Council (UK) Advanced Life Support manual and was launched in October 2021.
