Who invented automated external defibrillators?

The AED is just a "democratisation" of a medical device used in hospital.

The real "invention" was the use of a electrical shock to stop an heart arythmia. I don't remember his name, but an American did the first test on a animal in the early 40ies.

Doctor Claude Beck made and succeeded the first test on a young boy in the late 40ies with a device created by a friend of him.

If you ever know the missing names, please, could you improve this topic ?

The defibrillator was invented by Dr. William Bennett Kouwenhoven and a team of medical colleagues in 1933, in the basement of Shaffer Hall. Koewenhoven noted that a low-voltage electrical shock caused a ventricular fibrillation in humans, a process where the heart ceases beating, but continues to quiver, or fibrillate, rapidly.

What are three conditions or diseases that can cause a heart attack?

Three conditions or diseases that can cause a heart attack are: obesity, high blood pressure and diabetes.

What causes sed rate to be high?

What causes Erythrocyte sedimentation rates to be high?

The erythrocyte sedimentation rate (ESR), also called a sedimentation rate is the rate at which red blood cells precipitate in a period of 1 hour. This indicates a degree of inflammation. The test is performed by putting anti-coagulated blood in an upright tube, called a Westergren tube. The rate at which the red blood cells settle to the bottom is measured and reported in mm/h (millimeters per hour).

ESR is governed by the balance between pro-sedimentation factors, mainly fibrinogen, and those factors resisting sedimentation, i.e the negative charge of the erythrocytes (zeta potential). If there is an inflammatory process in action, there is a high proportion of fibrinogen in the blood and this results in red blood cells sticking to each other. The red cells form stacks called 'rouleaux' and these settle more quickly.

ESR increases where there is inflammation. ESR also increases in pregnancy or rheumatoid arthritis.

What can result in an increased risk of heart disease?

# Family history (either familial heart disease, inherited high cholesterol or LDL) # Excess weight # Diabetes # Smoking # Poor diet (high fat, high cholesterol, insufficient dietary fiber) # Sedentary lifestyle (no exercise) # Stressful lifestyle (constant worry)
Factors:

- lack of exercise

- vigorous activities

- foods rich in hydrogenated fats and alcohol

- poor lifestyle

- emotional stress

What are complex carbohydrates that aids elimination and may help prevent heart disease and cancer?

Dietary Fiber is the complex carbohydrate that aids elimination and may help prevent heart disease.

How does Ayurvedic medicine treat angina associated with ischemia?

Abana, a mixture of herbs and minerals used in Ayurvedic medicine, may reduce the frequency and severity of angina attacks.

Cardiovascular disease is a non-communicable disease?

A disease that cannot be spread from person to person is non-communicable. For example, lung cancer can make a person cough. But they won't give me cancer from coughing (though the cough can still spread viruses or bacteria). A person's heart disease is not "catch-able".

What is a diagnosis of benign hypertensive heart disease without heart failure?

Hypertension means high blood pressure.

Blood pressure readings are measured in millimeters of mercury (mmHg) and usually given as 2 numbers. For example, 140 over 90 (written as 140/90). * The top number is your systolic pressure, the pressure created when your heart beats. It is considered high if it is consistently over 140. * The bottom number is your diastolic pressure, the pressure inside blood vessels when the heart is at rest. It is considered high if it is consistently over 90. Either or both of these numbers may be too high. Pre-hypertension is when your systolic blood pressure is between 120 and 139 or your diastolic blood pressure is between 80 and 89 on multiple readings. If you have pre-hypertension, you are more likely to develop high blood pressure at some point. I hope this would be help full for you

thank you

THANK YOU,

Irregular sleep cause heart attack?

yes because my grandfatherhad one and he woke up and he had heart problems

What are the stages of congestive heart failure?

i FEEL I AM ENTERING LAST STAGE HEART FAILURE. i JUST WANT TO KNOW WHAT TO EXPECT

I watched my mother at the end of congestive heart failure...we all did as a family. If you would like to know what to expect I would rather discuss this with you privately instead of where everyone can see and it would be more respectful to do so privately...but if you want me to post the answer on here just let me know...my mother died on march 8th.2010..one month tomorrow and my dad was diagnosed yesterday with CHF...he is now in the hospital to get the swelling reduced....so with my answer to your question I have the experience to give you what you are looking for and I am also a nurse..just let me know.

What do I need to know about congestive heart failure treatment?

The first thing you must find out is if you are being treated for right or left sided heart failure. There are different treatments for each type. Medication is the most common type of treatment in which case you should know exactly how to take your medications. The best way is to discuss all of your medications with your pharmacist

How is a defibrillator used?

A defibrillator is primarily used for two conditions, Ventricular Fibrillation (V-Fib) and Ventricular Tachycardia (V-Tach). V-Fib is when the heart basically twitches and V-Tach is when it beats too fast to actually move blood. A defibrillator will NOT work if there is no electrical rhythm. If the heart is not beating and has no electrical activity at all (Asystole) then contrary to what happens in the movies, using a defibrillator would be pointless. In this situation, the only thing that can possibly "bring the patient back" is full life-support and cardiac drugs.

-----------------------------------------------------------------------------------------------------------------

Few opportunities to "bring back" one who has died are as time sensitive as defibrillation. With trauma we have the golden hour. In the best EMS systems in the US with the fastest response times the save rate for out of hospital cardiac arrest is only 2%-15%. We are making some major changes for the better the last 2 years with the advent of Public Access Defibrillators, Hands Only CPR, and cerebral resusitation such as rapid cooling and induced comas in the hospital.

We need to get a patient in Sudden Cardiac Arrest defibrillated in 1 to 3 minutes for a 70%-90% resusitation rate. Waiting the 8 minutes average response time for first responders equates to a 20% save rate or less.

Any time a patient is not breathing and appears to be dead ( with few exceptions that it would not be appropriate to go into here) you should apply the AED as soon as possible. Do not delay CPR to wait for the AED but immediatly on arrival of the AED stop CPR as the pads are ready to be applied. If the arrest is witnessed ( if they have been down less then 5 minutes) immediatly allow the AED to analize the rhythm and follow it's instructions. If there will be a delay in arrival of the AED begin rapid compressions without breathing stopping when the AED has arrived and the pads are ready to be placed. If you have oxygen available put them on high flow oxygen with a nonrebreathing mask, air will be moved as in breathing as you compress and allow the chest to expand, after all, that is how you are breathing as you read this.

If you do not know how long the patient has been down but it is likely more then 5 minutes do 200 compressions prior to applying the AED then follow it's instructions.

If you are not currently certified in AED but have been trained in the past most States include you in the Good Samaritan limited immunity statutes. If nobody is using the AED then you should use it. The machine is so smart and so fail-safe that 6th graders with minimal training have demonstrated they can effectivly and safely use it.

An AED can not shock a patient who is breathing and is not in a cardiac rhythm that requires a rapid shock to survive. No matter what you do or how many times you push the button you CAN NOT shock a patient who's life does not depend on you doing so.

You do NOT have time to wait for Fire/EMS/PD to arrive, if you see or know there is an AED there and the patient is not breathing turn it on, follow the instructions given regardless of if your training is current or not.

Factors that can lead to heart disease?

High blood pressure, stress, smoking, genetic factors, obesity, age.

What is known to correlate most strongly with reduced risk of deaths from heart disease?

People who exercise regularly, eat a healthy diet, and manage stress are less likely to have heart disease. A healthy lifestyle will offset internal risk factors such as age, gender, family history, and ethnicity. Many ethnic groups, including African Americans, have an increased risk of heart disease.

What happens during a heart attack?

In a heart attack (myocardial infarction) the heart is deprived of oxygen, and this eventually causes necrosis of the deprived cardiac tissues. This tissue death can result in heart failure and deadly arrhythmia.
Basically plaque builds up in the coronary artery and when the plaque hardens it explodes and platelets (cells that help to clot arteries and veins when they are cut) come in and prevent further release of the plaque that has explodes. However, this clotting can block an artery completely and stop blood flow to a part of the heart. When the blood flow stops, so does the oxygen to that part of the heart. Because of the lack of oxygen to keep the muscle going, muscle cells die in the heart, that's what happens in the heart during a heart attack!

When you have a heart attack the heart stops beating. It's because it clogs up the heart and you sometimes you will die or have brain damage


when you have a heart attack some of your heart cells stay without oxygen (Hypoxia )which may hurt or kill them related to how fast you get a medical care .

How long can a chihuahua live with heart failure?

Dogs can live with congestive heart failure. Dogs can live a few years if the condition is treated properly with medications and diuretics.

How is heart disease spread among humans?

The health of your heart is an outcome of some specific factors like your blood vessels stiffness, circulation in the vessels, and the amount of blockage in your arteries. These factors can be affected by many things that you do in life like your physical activity, consumption of alcohol, smoking and diet. The approach you need in order to maintain a healthy heart should be a method that fits well with these factors. Therefore i think that the risk of a heart disease should be the focus instead of which way to chose to prevent it. The best way is to focus on your heart and chose a method or treatment that provides specific results in that area (your heart health).

EECP treatment or ECP treatment (External counter pulsation) is as simple as a massage (but is done by a machine) and would help you in creating multiple natural bypasses in your heart. This treatment involves no invasive surgery or medicine use. It is effective because it results in opening up of newer blood vessels in your heart ( a process known as angiogenesis). It is also beneficial for patients with high blood pressure, diabetes, kidney disease, high cholesterol, obesity, ischemic stroke and many more diseases.

What non-communicable diseases attack the heart?

Your use of the word "attack" along with the word "non-communicable" makes me wonder whether you really mean what you seem to mean. Micro-organisms attack the body, but they're communicable. Perhaps you meant to say "affect the heart"...? There are many non-infectious cardiac diseases. These include congenital anomolies such as Tetralogy of Fallot, coronary artery disease, left and right ventricular dysfunction (also known as heart failure), arrhythmias such as atrial fibrillation, connective tissue diseases such as amyloidosis, and many others. Also, there are diseases which are non-cardiac but which affect the heart's function. These include pulmonary hypertension, vasculitis, anxiety, drug abuse, and many others.

What is ischaemic heart disease?

Ischemic heart disease is a medical condition described by a restricted blood flow through arteries in the heart muscle. These arteries cannot carry sufficient oxygen to several areas of the body supplied by such blood vessels. This condition can result in a heart attack.

In the story tell tale heart what disease does the narrator have?

It is never directly said so but the narrator shows many of the signs of Mercury poisoning. This was an occupational hazard of Hatters who used Mercury in the preparation of furs in the manufacturing of hats. This is the source of the saying 'Mad as a Hatter.'

Why heart failure occur?

The briefest medical explanation for the occurrence of cardiac failure is the result of two completely different viruses or infections are present at once, resulting in not heart attacks but failure of the hearts valves causing cardiac arrest.
