What is a pre -cordial blow?
Prusscordial wound is a potentially life -saving procedure that is usually performed by a trained physician. This procedure includes a sharp stock exchange in a specific location on the thoracic crust or predator and is usually given when a person has life -threatening heart problems of ventricular fibrillation or ventricular tachycardia. Presordial wound is then quickly followed by other skills to save life, such as cardiopulmonary resuscitation (CPR). If the procedure is performed by someone without proper training, it may cause further damage to the patient because the wound must be well focused. Chamber fibrillation concerns a state where the heart chambers begin to shake, unlike the contract and the chamber tachycardia is when the heart rhythm is too fast.
This procedure is trying to interrupt the arrhythmia of the heart and reset it to a normal rhythm. It is better to make a precordial blow at the beginning of the and tachycardia fibrillation. Presordium is located above the heart and chest area. If it is incorrectly delivered, a precordial wound cancause the patient to suffer from cardiac arrest due to trauma, as well as potentially burst thoracic bones. The procedure was supported when an ambulance accidentally that the patient was transported to the hospital, hit the wound and the patient's heart rhythm was repaired.
The assumed wound has the negative potential of conversion of ventricular tachycardia into ventricular fibrillation and therefore some countries no longer recommend this procedure. Research has shown that the wound generates only about 30 jouls, while up to 360 joules are usually necessary to cause a stable heart rhythm. Some medical experts say that with a lack of electrocardiographic images and evidence that the procedure works, evidence is not convincing. However, some studies recommended that the preliminary building procedure be restored to medical manuals. The reason is that if a patient is without a pulse and has not been successful with resuscitation, there may be a precordial bun the difference between lifeor by dying the patient.
When performing the preliminary procedure of the fastener, the emergency physician (EMT) will usually hold a fist of about 12 inches (about 30 cm) above the patient's thoracic bone. The fist is then dropped with a sharp suddenly to the thoracic game. This technique can also be complemented by drum stimulation, which is a number of these rhythmic strokes that are designed to artificially maintain a heart rhythm, until other types of stimulation are available.
