Use of cognitive aids in paediatric out-of-hospital cardiac arrest

A survey study of 39 EMS agencies across six states of the United States was carried out. The survey (Appendix A, online) was developed as part of a larger study examining preventable serious adverse...

Hyperventilation in cardiac arrest—a systematic review and narrative synthesis

This review followed a focused literature search of three databases—CINAHL, MEDLINE and ScienceDirect—from 1 January 2000 to 27 April 2022. Only human, adult, prehospital studies were included. Papers...

Attempting to prevent hyperoxaemia after out-of-hospital resuscitation

This literature review has limitations. A systematic review was not possible because of financial restraints. However, by following a detailed methodology and recording the steps taken, a valid...

Chest compression efficacy of child resuscitators

In a cardiac arrest, a 911 dispatcher can often coach a bystander to perform chest compressions if CPR has not been initiated. In the case that a lightweight resuscitator such as a child has made the...

Influence of time on the predictive value of the post-resuscitation ECG

To investigate the influence of time on the predictive value of the post-ROSC ECG, patients over the age of 18 were sought who had experienced an OHCA, had been successfully resuscitated, had received...

Focused ultrasound in out-of-hospital cardiac arrest by advanced paramedics

Of the total number of OHCA emergency calls attended by the LAS for 2018, 1444 were also attended by an APP. The numbers of patients who underwent FoCUS were similar to those who did not (744/1,444:...

Clinical case review: out-of-hospital cardiac arrest following thyroid storm

The patient, a woman in her late 20s, suddenly collapsed at home without warning and was found to be unconscious and not breathing by her partner. Immediate basic life support was given via ambulance...

Mechanical chest compressions and survival in the emergency setting

This systematic review will endeavour to demonstrate whether the use of a mechanical chest compression device will be a positive factor in improving survival in the cardiac arrest scenario. In...

Focused cardiac ultrasound in out-of-hospital cardiac arrest: a literature review

Although the use of ultrasound is well established in hospitals, it did not emerge in the prehospital environment until the 1990s in the United States. Furthermore, paramedic use of ultrasound has...

Cerebral oximetry monitoring in OHCA

Cerebral oximetry uses near infrared spectroscopy (NIRS) to measure transcutaneous cerebral tissue oxygen saturation. This reflects perfusion in the cerebral microcirculation (Genbrugge et al, 2016)....

Paramedic views on clinical research in cardiac arrest

Of the paramedics who were eligible, 60% responded to the exit survey (n=101)..

SAR helicopter paramedic practice: EtCO2 measuring to assist with CPR attempts

EtCO2 is the concentration of CO2 in exhaled air, and approximates the partial pressure of CO2 in arterial blood (PaCO2). Values of PaCO2 usually range between 4.6-6 KPa (Valente, 2010; Pantazopoulos...

Cardiac arrest and the role of transthoracic echocardiography

Massive acute pulmonary emboli (PE) is a reversible cause of cardiac arrest, with thrombolysis being the first line of treatment (British Thoracic Society, 2003). Occlusion of pulmonary blood flow is...

Which resuscitated patients benefit from PPCI after out of hospital cardiac arrest?

“Which resuscitated patients benefit from PPCI after an out of hospital cardiac arrest?” .

Therapeutic hypothermia in cardiac arrest

It is important to understand how the body is affected at the time of cardiac arrest and during the reperfusion that occurs following successful resuscitation. While achieving a ROSC in OHCA is not a...
