“…The impact of CFIO on patient-centred outcomes is still unclear. 5 , 7 , 11 To our knowledge, only two trials have compared the use of CFIO to other methods of ventilation in human studies. 5 , 7 These two randomized controlled trials included 95 and 696 patients and were conducted in France.…”

“…While the CFIO device maintains a positive alveolar pressure, ventilation is delivered by the concomitant chest compressions to achieve adequate gas exchanges. 5 – 7 The impact of CFIO on patients’ outcomes is unclear but CFIO was associated with improved gas exchange parameters 5 , 7 – 11 and increased coronary perfusion pressure 10 in small human cohort studies and animal model studies.…”

Introduction: In 2018, a continuous flow insufflation of oxygen (CFIO) device (b-card™, Vygon (USA)) placed on a supraglottic airway (SGA) became the standard of care to ventilate patients during adult out-of-hospital cardiac arrest (OHCA) care in Quebec–Capitale-Nationale region, Canada. This study aims to assess the paramedics’ perception as well as the disadvantages and the benefits relative to the use of CFIO during OHCA management. Methods: An invitation to complete an online survey (Survey Monkey™) was sent to all 560 paramedics who are working in our region. The survey included 22 questions of which 9 aimed to compare the traditional manual ventilation with a bag to the CFIO using a 5-point Likert-type scale. Results: A total of 244 paramedics completed the survey, of which 189 (77.5%) had used the CFIO device during an OHCA at least once. Most respondents felt that the intervention was faster (70.2%) and easier (86.5%) with the CFIO device compared with manual ventilation. CFIO was also associated with perceived increased patient safety (64.4%) as well as paramedic safety during the evacuation (88.9%) and the ambulance transport (88.9%). Paramedics reported that physical (48.1%) and cognitive (52.9%) fatigue were also improved with CFIO. The main reported barriers were the bending of the external SGA tube and the loss of capnography values. Conclusion: The use of CFIO during adult OHCA care allows a simplified approach and was perceived as safer for the patient and the paramedics compared with manual ventilation. Its impact on patient-centred outcomes needs to be assessed.

“…Boussignac tube, or with the combination of an oropharyngeal airway and standard mask with non-rebreather reservoir. Current evidence on this novel strategy derives from two randomized controlled trials (RCTs), enrolling 95 and 944 Out-of-Hospital Cardiac Arrest, respectively, in which the Boussignac tube was used for passive oxygen delivery [15][16][17]. No differences in any survival outcomes were observed [17].…”

Purpose of reviewThe purpose of this review was to give an overview of the most significant updates in resuscitation guidelines and provide some insights into the new topics being considered in upcoming reviews.Recent findingsRecent updates to resuscitation guidelines have highlighted the importance of the earlier links in the chain-of-survival aimed to improve early recognition, early cardiopulmonary resuscitation (CPR) and defibrillation. Empowering lay rescuers with the support of emergency medical dispatchers or telecommunicators and engaging the community through dispatching volunteers and Automated External Defibrillators, are considered key in improving cardiac arrest outcomes. Novel CPR strategies such as passive insufflation and head-up CPR are being explored, but lack high-certainty evidence. Increased focus on survivorship also highlights the need for more evidence based guidance on how to facilitate the necessary follow-up and rehabilitation after cardiac arrest. Many of the systematic and scoping reviews performed within cardiac arrest resuscitation domains identifies significant knowledge gaps on key elements of our resuscitation practices. There is an urgent need to address these gaps to further improve survival from cardiac arrest in all settings.SummaryA continuous evidence evaluation process for resuscitation after cardiac arrest is triggered by new evidence or request by the resuscitation community, and provides more current and relevant guidance for clinicians.
