This literature review examines the scope of paramedic practice in managing cardiac arrest, a critical emergency medical situation. It explores various interventions and their impact on patient outcomes, including advanced airway management, CPR, and therapeutic hypothermia. The review synthesizes findings from multiple studies, including a nationwide population-based study, randomized controlled trials, and investigations on pre-hospital cooling. The results highlight the importance of paramedics in providing timely and effective emergency care, with studies indicating improved neurological outcomes and survival rates following paramedic arrival. However, the review also notes mixed results regarding the impact of specific interventions, such as therapeutic hypothermia, indicating the need for further research and refinement of paramedic protocols to enhance patient care during cardiac arrest. The review concludes that paramedics play a crucial role in restoring circulation and breathing through CPR, resuscitation, and hypothermia, which is closely related to other healthcare positions.
