How a defibrillator works

Defibrillators are powerful pieces of equipment that can save a person’s life. They are designed to help support those who are affected by a cardiac incident. It allows paramedics and even bystanders to help save the individual’s life.

When a person experiences a cardiac arrest, their heart’s electrical rhythm is affected and stops the heart from beating at a normal rhythm. This arrhythmia means that the heart can no longer effectively pump oxygenated blood around the body, which has an impact in several ways. If the blood flow to the vital organs in the body and the brain is stopped, the individual will collapse, and you won’t be able to detect their breathing or their pulse. At this point, they only have minutes to be able to survive, and a defibrillator can help with this.

The defibrillator delivers a short electrical shock to the cardiac muscle area, and this recharges the heart cells allowing them to try and re-establish a working rhythm in the heart. The system inside the defibrillator is so sophisticated that it can detect any arrhythmias in the heart and will deliver the right amount of volts when it shocks the patient to help restart their heart.
