 Such a system provides, in essence, a "zero response time," and can have an enormous impact on positive patient outcomes.A paramedic has a high level of pre-hospital medical training and usually involves key skills not performed by technicians, often including cannulation (and with it the ability to use a range of drugs to relieve pain, correct cardiac problems, and perform endotracheal intubation), cardiac monitoring, tracheal intubation, pericardiocentesis, cardioversion, needle decompression and other skills such as performing a cricothyrotomy.The most important function of the paramedic is to identify and treat any life-threatening conditions and then to assess the patient carefully for other complaints or findings that may require emergency treatment.
