Left Ventricular Assist Devices Essay

If a pacemaker is implanted to control Greg’s heart rate, he will need or will be forced to make certain life changes to maintain the device. There are many precautions that he will need to take such as keeping electronics a certain distance from directly over the pacemaker and may have other issues in any metal detector situations (Staff, Pacemakers, 2016). In my opinion I think that Greg will be able to play sports again; but, certain sports may be out of the question. Due to the fact of the contact in certain sports, Greg would risk getting hit again putting him as risk for another

The LifeVest is a defibrillator that is placed in a vest that patient is able to wear under his cloth. The vest helps save and individual in cardiac arrest. My patient was going to use this device because of his cardiac condition and due to his recent MI; these factors put him at a higher risk of cardiac arrest. It was amazing to watch how all the technology in the vest can save someone’s life. Watching my patient through his vest fitting and teaching was the highlight of the day. It was the first time that I

Also, this document analyses and complete three evidence-base practice articles in nursing care with QSEN guidelines. Lastly, this documents review the safety concerns that are related to the technology when it

It is important to follow instructions from your health care provider about caring for your ventricular assist device (VAD) at home (destination therapy). You will continue to work with a health care provider who specializes in VADs (VAD coordinator) and a heart specialist (cardiologist).

The device is needed when a person’s heart fails to operate correctly. A person needing an artificial heart would be extremely ill that is they would not be able to function like an everyday person. E.g. – walking.

This is done by the pacemaker being connected to the heart by one or more wires called the pacing leads which are usually attached to the right atrium as this is where the electrical activity is emitted by the Sino atrial node (SA) node. For instance when someone has a slow heart beat (bradycardia) due to the electrical signals not being conducted properly or blocked the pacemaker will send the an electrical signal to the heart initiating a new excitation wave which will re set the heart at a sinus rhythm. Pacemakers act as signal transmitter that interprets the electrical signal then decides whether to initiate another signal such, as if the heart electrical signal was blocked it would lead to cardiac arrest however the pacemaker picks up that no electrical signal has been initiated and therefore generates one in order to keep the heart pumping. In addition to these pacemakers have special sensors that pick up when you are moving and your respiration rate; as if the device doesn’t recognise an increase in body activity it can generate electrical signals for no reason as it think that your pulse rate is to high (tachycardia), this is called the responsive rate and is vital to ensure rhythmic

McCarty and Shaffer (2015) state "we now know that the normal resting rhythm of the heart is highly variable rather than being monotonously regular..." (p. 47) showing the need for a new type of control technique. As a stand-alone treatment, HRV is shown to influence the regulatory system of the heart allowing for controlled, rhythmic beating in the patient using the HRV biofeedback device.

The heart’s moves oxygen-rich blood from the lungs to the left atrium onto the left ventricle which then pumps it to the rest of the body. The left ventricle generates the heart’s pumping power therefore it is larger than the other chambers. In left-sided heart failure, the left side of the heart works harder to pump the same amount of blood that is normally pumped. There are two types of left-sided heart failure- the systolic and the diastolic. In systolic failure, the left ventricle is not able to normally contract and the heart cannot push enough blood into the circulation. In systolic failure, the left ventricle is not able to relax because the muscle has become stiff. As a result, the heart cannot properly fill with blood during resting period between each beat. Right-sided heart failure is another type of heart failure that results from the failure of the left-side. The heart’s pumping action moves blood that returns to the heart though the veins through the right atrium and then onto the right ventricle which pumps the blood back out of the heart into the lungs to be replenished with oxygen. When the left ventricle

With the constant change in the medical field, it is mandatory for all nurse anesthetists to keep up with everything to give the best care. The newest of these technologies is the mobile stroke treatment unit. Strokes have a profound impact on someone’s health. The consequences of a stroke can be devastating. In order to improve stroke outcomes, many hospitals in Germany and the United States are now using specially equipped mobile stroke treatment ambulances with all the necessary elements for the evaluation and treatment of strokes. Another new technology is the leadless cardiac pacemaker. The leads in pacemakers detect a patient’s heart rhythm and relay the information to the generator and enclosed computer chip, which then adapts its electrical responses to the patients’ needs so the heart beats on a normal rate. Over time, the leads break and wear out, insulation around it can crack, and could become infectious. A wireless cardiac pacemaker that’s no bigger than a large vitamin is 10 percent the size of a traditional pacemaker. In the space of 15 to 30 minutes, the miniaturized battery-controlled device can be implanted directly in the heart without surgery. This pacemaker nanotechnology has eliminated surgery, lumps and scars on patient’s chest, restrictions on daily physical activities, as well as any complications stemming from any malfunctioning insulated connecting leads. With all these new technologies coming into play

A pacemaker consists of a battery, computerized generator, and wires with sensors called electrodes. These electrodes detect the electrical activity of the conducting cells and then send the data back to the generator via the wires. If the pacemaker senses irregular activity, it will deliver a low energy pulse to the heart. For reference, the current delivered by a pacemaker is about one thousandth the size of the current needed to start a car. Most people report feeling a fluttering in their chest, if anything at all. Another interventional option is the ICD, which acts as both a pacemaker and a defibrillator. An ICD consists of a pulse generator, which monitors your heartbeat, and the leads. The leads of the ICD have electrodes that connect to the heart chambers. If an irregular rhythm is detected, a low energy pulse is delivered to prompt the heart to start beating normally. If the low energy pulse is not effective or sufficient, the ICD switches to a high energy pulse called defibrillation. People report defibrillation as feeling like you are being kicked in the

In an effort to address the issue of radio frequency radiation exposure in this community, we will provide a background on the sources of radio frequency radiation as well as the known and suspected health effects. We will also proposed two epidemiological studies and discuss risk management and

Furthermore the group also mentioned that, even though the frequency for non-ionizing radiation is less dangerous, it is still possible to have side effects that may affect to our personal lives. There was a class where at the end we had a very brief discussion about radiation from electronics and the topic of cell phones/smart phones was brought up by few students when they were asked about their opinion or personal experience. Some side effects they mentioned from using their cell phones/smart phones constantly were having problems falling asleep along with minor headaches.

The good news is that there are a few simple solutions that help in lowering one’s risk of exposure to radiation. First of all, holding the phone away from the face and using the speaker phone instead leads to ten thousand times less exposure. In addition, using a wired headset gives less exposure into the ear. Secondly, since carrying the phone in one’s pocket leads to exposure to his or her bone marrow, one should simply keep the phone off. Lastly, the weaker the signal in the phone, the more the radio frequency signal has to enhance itself to get into the phone; thus, one should avoid using the phone if it appears to have a weak signal. Basically, one gets greater exposure to radiation with a weaker signal. Indeed, it is never too late to prevent oneself from such hazards.

As for the second design, low frequency excitations are present due to the worker’s motion including walking and contraction and expansion of his muscles. These low excitation motion can provide viable amounts of wasted mechanical energy that can be converted to power many critical devices including sensors for oxygen monitoring, pacemakers, defibrillators, cell phones, and wireless sensors and actuators. A significant impediment in the
