An analysis of the Afrikaans telephonic descriptors of cardiac arrest in a Western Cape Emergency Control centre
Introduction: Out of Hospital Cardiac Arrest (OHCA) is a time-sensitive emergency which requires prompt identification and emergency care in order to reduce morbidity and mortality. The first step in recognising OHCA is rapid identification by the emergency dispatch centre. Identification of such …

An analysis of the isiXhosa telephonic descriptors of cardiac arrest (ca) in a Western Cape emergency control centre
Introduction: Out-of-hospital cardiac Arrest (OHCA) represents a considerable public health challenge, characterised by its critical time sensitivity, high morbidity, and poor survival rates. Despite decades of low survival rates, OHCA survival has been a constant concern for healthcare systems …

The fight against time in prehospital cardiac arrest - a true medical emergency
… after an out-of-hospital cardiac arrest (OHCA) are one in ten. The majority of survivors have no or relatively mild neurological sequelae. Interventions are time critical and well-timed management is challenging. All aspects of resuscitation in an OHCA are based on knowledge of clinically …

An exploration of the recognition of deterioration in ems witnessed cardiac arrest: improving national outcomes from out-of-hospital cardiac arrest (OHCA).
… EMS witnessed out-of-hospital cardiac arrest (OHCA) in Scotland. I extracted key findings from these papers, analysed their contribution, and examined the links made to demonstrate their influence on national guidelines and policy development into one progressive and coherent body of work, to …

Mortality Risk Among Patients Who Present to Hospitals with Out-Of-Hospital Cardiac Arrest and ST-Elevation Myocardial Infarction
… with an out-of-hospital cardiac arrest (OHCA), decisions for immediate coronary angiography are made when the likelihood of survival is highly variable and unknown. A simple prognostic tool that can identify patients with a very high mortality risk upon hospital presentation may inform …

Views and perceptions of advanced life support practitioners on initiating, withholding and terminating resuscitation in out of hospital cardiac arrest in the emergency medical services of the Western Cape
… cause of out-of-hospital cardiac arrest (OHCA). (2) The overall prognosis and neurological outcome associated with OHCA are rather poor and have remained unchanged for the past thirty years. There is a survival rate of approximately 10% following discharge from hospital. (3, 4) This is …

Aspects of post-resuscitation care after out-of-hospital cardiac arrest
… are due to out-of-hospital cardiac arrest (OHCA). In Sweden, approximately 10,000 persons suffer an OHCA annually and in 5000 cardiopulmonary resuscitation (CPR) is initiated. The successful return of spontaneous circulation (ROSC) and admission to hospital are just the first steps towards …

Predictors of survival in cardiac arrest
… and 10% for out-of-hospital cardiac arrest (OHCA). Many factors influence survival, ranging from the patient’s age, gender and comorbidities, to the conditions surrounding the arrest, to the emergency medical service (EMS) response time, to post-arrest treatment strategies. In study I, the …

The development and testing of a training intervention designed to improve the acquisition and retention of CPR knowledge and skills in ambulance paramedics
… in the out-of-hospital, cardiac arrest (OHCA) survival rates. Reports indicate that, although the incidence and outcome of OHCA vary across the globe, the median reported rates of survival at hospital discharge have remained below 10% for the 30 years preceding this study. One of the …
