Pacemaker Pulse Generator
A pacemaker is a tiny device that contains a pulse generator and weighs between 20 and 50 grams. The pulse generator is made up of a battery and a small computer circuit with wires that attach to the heart referred to as a lead. The pulse generator sends out electrical impulses at a set frequency. Modern pacemakers are engineered to respond to the body’s demands. When the heart is beating too slowly, the pacemaker’s closed feedback control system sends a signal. A sensor that measures the patient’s respiration rate aids this process. When a patient is active, the discharge rate increases, and doctors refer to this as rate responsiveness.
The Reaction of The Skin to Pacemaker Materials
Without parallel advances in biotechnology, advancements in cardiovascular procedures would not have been conceivable. Biomaterials are used in a variety of applications, including prosthetic heart valves, ventricular assist devices, cardiac pacemakers, and endovascular implants, as well as suture material and bioadhesives. Materials and devices used to restore Anatomical and Physiological circulatory qualities include risks and potential complications, both in the short and long term after implantation into the recipient. Metals and alloys, polymers, and ceramics are used as implant building blocks. Collagen, hyaluronan, and dextran are examples of naturally occurring materials. Polylactic acid, polylactic-coglycolic acid, polyvinyl alcohol, and other synthetic polymers are utilized to make implanted devices. The majority of implanted devices are complex composition implants, which are made up of more than one type of material. Although these materials have been extensively employed with excellent functional outcomes, there remain concerns about biocompatibility. Novel metal alloys have been developed to overcome physical limits and improve the biomechanical characteristics of metals. Certain alloys have unique features in addition to excellent physical and chemical capabilities in terms of strength, durability, and corrosion resistance. One of the most extensively used materials in the medical prosthesis is nickel-titanium (nitinol) alloys, which have shape memory and exceptional elasticity. The reaction of tissue to implanted elements is a complicated process. It involves several processes, some of which involve the creation and activation of interacting humoral and molecular elements. These processes might be short-term (minutes) or long-term (years).
Patients Awareness and Education
Pacemaker batteries last 6-12 years and are replaced by accessing the subcutaneous pocket. To promote healing and prevent lead displacement, the patient is recommended not to lift the arm above the pacemaker level. To avoid infection, it is also recommended that you avoid showering and gently cleanse the incision site, avoiding the use of powder or lotion.
Temporary versus Permanent Pacemakers
Temporary Pacemaker
1. Intended for use for a brief period, most likely while in the hospital.
2. To assist patients until they recover or until permanent solutions are found.
3. Endocardial leads and epicedial cables are sometimes only used for a short period.
4. Externally positioned
5. The temporary generator is about the same size as a compact paperback book in terms of size.
Permanent Pacemaker
1. Pacemakers that are designed to be used for a long time.
2. The generator is placed in a subcutaneous pocket and consists of endocardial leads.
3. Depending on numerous conditions, they can last anywhere from 6 to 12 years.
4. Internally, in most cases. It weighs less than one ounce and is about the size of a credit card.
