Background The so called ABCDE approach (Airway-Breathing-Circulation-Disability-Exposure) is a golden standard of patient assessment. The efficacy of using cognitive aids (CA) in resuscitation and peri-arrest situations remains an important knowledge gap. This work aims to develop an ABCDE CA tool (CAT) and study its potential benefits in patient condition assessment. Methods The development of the ABCDE CAT was done by 3 rounds of modified Delphi method performed by the members of the Advanced Life Support Science and Education Committee of the European Resuscitation Council. A pilot multicentre study on 48 paramedic students performing patient assessment in pre-post cohorts (without and with the ABCDA CAT) was made in order to validate and evaluate the impact of the tool in simulated clinical scenarios. The cumulative number and proper order of steps in clinical assessment in simulated scenarios were recorded and the time of the assessment was measured. Results The Delphi method resulted in the ABCDE CAT. The use of ABCDE CAT was associated with more performed assessment steps (804: 868; OR = 1.17, 95% CI: 1.02 to 1.35, p = 0.023) which were significantly more frequently performed in proper order (220: 338; OR = 1.68, 95% CI: 1.40 to 2.02, p < 0.0001). The use of ABCDE CAT did not prolong the time of patient assessment. Conclusion The cognitive aid for ABCDE assessment was developed. The use of this cognitive aid for ABCDE helps paramedics to perform more procedures, more frequently in the right order and did not prolong the patient assessment in advanced life support and peri-arrest care.
European Resuscitation Council Guidelines for Resuscitation 2010 and Advanced Life Support Provider Course teaches that the open oxygen supply must be removed from the patient during defibrillation to the distance of minimum of 1 meter. Scientific articles describe few incidents of fire during defibrillation in oxygen – enriched atmospheres. It was performed a series of measurement of the oxygen concentration in the ambulance vehicle of 10 cubic meters. The measurements were made in parked vehicle. Patient was seated on the stretchers and oxygen was applied with oxygen mask on high flow (15 l per minute). The oxygen concentration was measured on different places in the ambulance car – the patient’s face, on the chest, on the wall in front of the car, on the wall in the rear and on the celling. We measured temperature, atmospheric pressure and humidity together with oxygen concentration. The result of our study showed that the oxygen concentration has risen from 20.9 % at all locations of the ambulance. In certain locations the concentration has increased at least to 30 %. It has prepared recommendations for defibrillation during oxygen administration according to the literature and our study.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
