Blood typically exits the wound in spurts, rather than in a steady flow; the blood spurts out in time with the heartbeat. The amount of blood loss can be copious, and can occur very rapidly. [10] Venous bleeding: This blood is flowing from a damaged vein. As a result, it is blackish in colour (due to the lack of oxygen it transports) and flows ...
An automated external defibrillator or automatic electronic defibrillator (AED) is a portable electronic device that automatically diagnoses the life-threatening cardiac arrhythmias of ventricular fibrillation (VF) and pulseless ventricular tachycardia, [1] and is able to treat them through defibrillation, the application of electricity which stops the arrhythmia, allowing the heart to re ...
Likewise, a 2022 systematic review on exercise-related cardiac arrests supported early intervention of bystander CPR and AED use (for shockable rhythms) as they improve survival outcomes. [ 86 ] If high-quality CPR has not resulted in return of spontaneous circulation and the person's heart rhythm is in asystole , stopping CPR and pronouncing ...
Cardiopulmonary resuscitation (CPR) is an emergency procedure consisting of chest compressions often combined with artificial ventilation, or mouth-to-mouth in an effort to manually preserve intact brain function until further measures are taken to restore spontaneous blood circulation and breathing in a person who is in cardiac arrest.
Rapid defibrillation outside of the hospital improves the chances of survival by as much as 30%, and involves using an automated external defibrillator (AED) to shock the patient's heart. [16] While CPR keeps blood flowing artificially, [17] rapid defibrillation is the only way to restart the heart and reset it to a healthy rhythm. [18]
Defibrillation is a treatment for life-threatening cardiac arrhythmias, specifically ventricular fibrillation (V-Fib) and non-perfusing ventricular tachycardia (V-Tach). [1] [2] A defibrillator delivers a dose of electric current (often called a counter-shock) to the heart.
It is supplied in a canister for use in an inhaler or in single dose vials for use in a nebulizer. [17] It is also used to treat and prevent minor and moderate bronchial asthma, especially asthma that is accompanied by cardiovascular system diseases, as it has been shown to produce fewer cardiovascular side effects. [18]
In 1864, the first steam-driven nebulizer was invented in Germany. This inhaler, known as "Siegle's steam spray inhaler", used the Venturi principle to atomize liquid medication, and this was the very beginning of nebulizer therapy. The importance of droplet size was not yet understood, so the efficacy of this first device was unfortunately ...
