What is pharmacologic management of ventricular fibrillation?
Patients who experience ventricular fibrillation (which is disorganized electrical activity occuring within the lower chambers of the heart) are resuscitated via defibrillation. Defibrillation consists of an electric shock usually delivered via conductive pads or paddles. It essentially resets all the cells of the heart in hopes that when electrical activity resumes, it will be organized and able to pump blood. Untreated, all ventricular fibrillation is fatal, and patients who are at known risk for experiencing this arrythmia can be provided with an implanted cardioverter defibrillator, or ICD. This is a device which is placed under the skin of the upper torso and connected to the heart with a wire. It contains a computer which will monitor the patient's heart at all times and deliver a shock if recognizes ventricular fibrillation or a related rhythm called ventricular tachycardia. There are also certain drugs, such as amiodarone and lidocaine, which can be given to a patient at known risk for ventricular fibrillation in order to make it less likely. These drugs usually work by making the cell membranes of the cells of the heart more electrically stable. Many of the same drugs can also be given if defibrillation is initially unsuccessful in order to help make it more effective. It should be noted that there is a very short window of time to treat ventricular fibrillation (permenant brain damage begins to occur approximately 4-6 minutes after the onset of the arrythmia), and the prognosis for these patients is generally very poor if they are not defibrillated immediately and transferred to a critical care setting.
When was the ICD Defibrillator invented?
Michel Mirowski conceived of and developed the implantable cardioverter-defibrillator (ICD). After building a prototype device, Mirowski tested and refined it in animals. Despite considerable skepticism and criticism from many of his colleagues, Mirowski implanted the first device in a human in 1980.1 In 1985, the FDA initially approved theICD, specifying that patients had to have survived 2 cardiac arrests to qualify for ICD implantation.
How long after your heart stops beating do you faint?
A person who suffers from cardiac arrest will faint at the same time or withing 1-2 seconds after suffering from cardiac arrest. There are different forms of cardiac dysrhythmias that a person can suffer from: Ventricular Tachycardia- is when the ventricles of the heart beat very rapidly and without much efficiency, a person can still be conscious while in ventricular tachycardia and live for hours in this rhythm. Eventually this rhythm will be fatal as not enough blood flow will be delivered to vital organs. Ventricular Fibrillation- is when the ventricles just "quiver" erratically and unable to produce a palpable pulse and a patient presenting in this rhythm will be unconscious although agonal respirations might still be noted. On an EKG this rhythm appears to look like a seismograph when an earthquake is happening, very erratic and inconsistent. Asystole- This is the final rhythm of cardiac arrest and exhibits no electrical activity of the heart. 99% of patients will not initially present in this rhythm as they usually progress from VT or VF into asystole. A patient in asystole on a EKG would show a "flatline" or no electrical activity of the heart.
How do you give a girl an anonymous Valentine?
Answer Anonymous can be fun initially but it can turn into creepy. To be playful, you can leave it on her/his car, mail it to her/him, have it delivered, etc. but I would not leave it anonymous for very long as it can scare someone.
How is the census in Ireland taken?
Census forms are delivered to every household and places like hotels, hospitals, where any people are. On the night of the census the forms are filled in and are then collected in the following days by the people who initially delivered them. Results are eventually released through the Central Statistics Office, whose website is below. The last census was in 2006.
Can you bypass liver by snorting?
When taken orally, a drug is first taken up by the liver, then delivered into the general circulation. When taken by injection, by skin patch, or by inhalation, the drug bypasses the liver initiallyand is delivered directly to the circulation. So initially yes. But ask a doctor or pharmacist before you snort anything your supposed to take orally.
Is initially an adverb?
The word initially is indeed an adverb, yes.An example sentence is:We were initially very excited about the trip.
How initially is used in a sentence?
Initially, I didn't want to write this sentence, but I changed my mind.
Is rigid a synonym for worse or is initially?
