11 Quality of bystander CPR by lay first responders: training versus real-world use of a novel CPR feedback device in singapore

Abstract

randomisation and the funding of prehospital critical care for OHCA. Method We aimed to answer the following questions: What are stakeholders' priorities for prehospital research? What are stakeholders' views on randomisation of prehospital critical care? How do stakeholders consider allocation of resources in prehospital care? We undertook a qualitative framework analysis of interviews and focus group with five key stakeholder groups: patients and public, air ambulance charities, ambulance service commissioners, prehospital researchers and prehospital critical care providers. Results Despite sharing a common appreciation of the concepts of scientific enquiry, fairness, and beneficence, the five relevant stakeholder groups displayed divergent views of research and funding strategies regarding the intervention of prehospital critical care for the condition of OHCA. The reasons for this divergence could largely be explained through the different personal experiences and situational contexts of each stakeholder group. Many aspects of the strategies suggested by the stakeholder groups only partially aligned with principles of traditional evidence-based medicine, but were held with strong conviction. Conclusion Analysis of the views of five stakeholder groups regarding research and the funding of prehospital critical care for OHCA revealed shared values, but a variety of different strategies to achieve these. This knowledge can help researchers in similar fields in the planning and presentation of their research, to maximise impact on decision making.

Responding to Cardiac Arrest in the Community in the Digital Age

“…37,38 New technology such as a credit-card size "CPRcard" provides visual feedback of compression depth and rate in real time, resulting in betterquality compressions. 39 Mobile phones might also be useful as a more accessible and cost-efficient refresher method for CPR training in lay responders. 40 Repeated reminder videos sent to user's smartphone via text in combination with regular training preserved participants willingness and confidence to perform CPR and provided support for the retention of CPR and AED skills.…”

A survey on technologies used during Out of Hospital Cardiac Arrest

“…After the dispatcher confirms that the patient is experiencing cardiac arrest, the next step is to guide the caller to perform CPR. CPR performed by bystanders plays a vital role in increasing the patient's survival chances 78,79,80,81 . Bystander CPR is necessary because the ambulance dispatched to the patient's location takes approximately 8-10 minutes, depending on the site of dispatch vehicles 82,83 .…”

“…However, these devices are expensive and are not publicly available for help during OHCA incidents. Some researchers are proposing smaller devices similar to the size of a credit card, which will help portability but still limit the use of these devices in an actual incident 78 .…”
