![]() However, the relationship between the effect of airway management in OHCA on actual CCF and patient outcomes is unknown. Advanced airway management with endotracheal intubation (ETI) or supraglottic airway devices (SGA) allows ventilation without interruption of chest compressions and is expected to increase CCF. Interruption for ventilation as synchronous CPR may have a significant impact on CCF. 5 Two methods are used for chest compressions and ventilation during cardiopulmonary resuscitation: synchronous CPR, a cycle of 30 uninterrupted chest compressions with a cycle of two ventilations or asynchronous CPR, and uninterrupted ventilation with advanced airway management. ![]() Among them, the interruption time of chest compressions for ventilation may have a significant impact on CCF. 4ĭuring prehospital resuscitation, rescuers may stop chest compressions for many reasons that are integral to patient care, such as ventilation, assessing heart rhythm and pulse, defibrillation, or tracheal intubation. 2, 3 American Heart Association guidelines for cardiopulmonary resuscitation recommend maintaining the CCF above 80% during CPR. Maintaining a high chest compression fraction (CCF percentage of time patients received compressions through constant chest compressions) is considered a key factor in achieving return of spontaneous circulation (ROSC) of OHCA resuscitation. “High-quality CPR” is key to improving the chance of survival for OHCA patients. 2010 122:S298–324.More than 120,000 out-of-hospital cardiac arrest (OHCA) victims were transported to the emergency room in Japan in 2015.Their one-month survival rates are low at <10%, 1 and improving prognosis of these cases is an urgent issue.

CCF during resuscitation may improve if there is a focus on improving these factors and requires validation in multicentric settings.Ĭardiac arrest cardiopulmonary resuscitation chest compression fraction defibrillation emergency department.Ĭopyright: © 2021 Journal of Emergencies, Trauma, and Shock.īecker LB, Ostrander MP, Barrett J, Kondos GT. ![]() CCF decreased when resuscitation lasted longer, during daytime when the defibrillator was used, the total team members increased, and also when the number of people giving chest compressions increased. The mean CCF for cardiac arrest patients was well within the targets of guideline recommendation. Diurnal variation (day, n = 35 mean 69.20% ± 7% and night, n = 20 mean 75.80% ± 5.6%, P = 0.001) and patients receiving defibrillation (receiving n = 10 mean 67.00% ± 4.11% and not receiving n = 45 mean 72.62 ± 7.42%, P = 0.005) were found to significantly affect CCF. The mean CCF was analyzed using descriptive statistics and was found to be 71.60% ± 7.52%. The total time taken for the entire resuscitation was noted by the device and CCF calculated. The feedback device Cprmeter2™ was placed on the patient's sternum at the beginning of resuscitation. Resuscitation was provided by trained health-care providers. Patients presenting to the emergency department in cardiac arrest at a single center were prospectively included in this study. We aimed to identify the mean CCF and its relationship with various factors affecting it. Targeting a CCF of at least 60% is intended to limit interruptions in compressions and maximize coronary perfusion during resuscitation. Chest compression fraction (CCF) is the cumulative time spent providing chest compressions divided by the total time taken for the entire resuscitation.
