Your personal assistant in challenging cardiac arrest scenarios. iArrest was developed to give healthcare professionals a powerful tool to navigate stressful and challenging cardiac arrest calls. Whether as a Paramedic on scene or as a clinician in hospital, this app can assist in running structured and effective adult cardiac arrest scenarios. Developed by an anaesthetist training in London, this app takes into consideration the most recent Resuscitation Council (UK) Guidelines 2015. It serves as an aide-memoire for basic tasks that can easily be overlooked in stressful scenarios. iArrest also incorporates a number of timers to assist with rhythm analysis, adrenaline timings and arrest duration. It will remind the user via audible and visual cues about necessary interventions even if a clinician’s phone is muted. iArrest has been programmed to prevent phones from going into sleep mode, in order to ensure continuous use throughout the arrest. iArrest will record the exact time an important event or an intervention has occurred and present the user with a detailed log of events. These logs can be copied to the clipboard and used for documentation and record keeping.
