Rythmic beats in the human heart are facilitated by chemical impulses. These impulses are produced by pacemaker cells that are specially structured to perform that function. However, in most cases these cells are affected by medication, stress, external stimuli and physical activity. These factors can increase or decrease the heart beats by changing the chemical impulses. Defibrillation is one of the most-well known but often misunderstood heart stimuli.
The the process of defibrillation includes delivering a jolt of electric current to the heart muscles. The electric current helps to depolarize muscles of the heart and hence to enable the pacemaker to reset and continue beating regularly. The devices that perform the function of defibrillation are known as defibrillators. The devices are made using different designs and have varying capabilities.
Movies and TV’s shows are nowadays are misleading by showing AED’s that are outdated. The prophylactic nodes provide the route through which defibrillation is performed. In order for the nodes to control the heart rate, the nodes are attached to a patient’s chest. The function of the nodes is to stimulate a shock heart rhythm through an electric shock. Unlike what is shown in movies and TV shows, patients of electric shocks do not convulse. A defibrillator functions by creating a small rhythmic contraction of the body muscles. Ventricular fibrillation is a cardiac rhythm, and it happens when the ventricle quiver rather than work in a pattern.
AED gadget can be found today in the market although the various companies manufacturing them. This can make it difficult in deciding where to start when purchasing Automatic external defibrillators. Some of the renown brands offering the devices include, CU medical, Physio control, Welch Alyn, Zoll, Phillips, Defib tech, Cardiac science and HeartSine. By having such a wide range of companies to choose from, some several factors should be considered before a purchase is made.
The Key Elements of Great Tips
The availability of information concerning AED’s on several online platforms helps in making a decision relating to the right purchase. On line information contributes to matching the budget with specific requirements of the required resuscitation gadget. The first consideration about the gadget of interest are the online reviews. Online reviews can be a great source of enlightenment. In checking the reviews, caution be taken so as to avoid overlooking on the reviews done by the manufacturer and not checking on those provided by the end users.
What No One Knows About Tips
One of the good examples of user reviews are the comments made by customers of Amazon. Customers in online platforms are not biased and give sincere opinions. End users provide insight on the merits and demerits of the AED’s they have been using. The problem with manufacturer reviews is that they give only the positive aspects of their defibrillators in order to convince customers to make purchases. An important aspect when looking at a review is the ability to compare the various devices and give their merits and demerits.
