Pulseless electrical activity From Wikipedia, the free encyclopedia. Pulseless electrical activity or PEA (also known by the older term electromechanical dissociation) refers to a clinical diagnosis of cardiac arrest in which a heart rhythm is observed on the electrocardiogram that should be producing a pulse, but is not.he approach in treatment of PEA is to treat the underlying cause, if known (e.g. relieving a tension pneumothorax). Where an underlying cause for PEA cannot be determined and/or reversed, the treatment of pulseless electrical activity is similar to that for asystole.

Nuclear electromagnetic pulse The E1 pulse is the very fast component of nuclear EMP. E1 is a very brief but intense electromagnetic field that induces very high voltages in electrical conductors. E1 causes most of its damage by causing electrical breakdown voltages to be exceeded.n nuclear EMP all of the components of the electromagnetic pulse are generated outside of the weapon. For high-altitude nuclear explosions, much of the EMP is generated far from the detonation (where the gamma radiation from the explosion hits the upper atmosphere).

- The pulse generator is internal in permanent pacemakers (subcutaneously or submuscularly) and external in temporary pacing. It can be set to a fixed-rate (asynchronous) or demand (synchronous) mode.

- Pulse oximetry is a procedure used to measure the oxygen level (or oxygen saturation) in the blood. It is considered to be a noninvasive, painless, general indicator of oxygen delivery to the peripheral tissues (such as the finger, earlobe, or nose).ulse oximetry technology utilizes the light absorptive characteristics of hemoglobin and the pulsating nature of blood flow in the arteries to aid in determining the oxygenation status in the body.

- Pulse Radar. Pulse Radar. A pulse radar is a radar device that emits short and powerful pulses and in the silent period receives the echo signals. In contrast to the continuous wave radar the transmitter is turned off before the measurement is finished.

Pulseless Electrical Activity (PEA) Rhythm Pulseless electrical activity usually has an underlying treatable cause. The most common cause in emergency situations is hypovolemia. PEA is treated by assessing and correcting the underlying cause.These causes can be summed up in the 6 H’s and 6 T’s of ACLS. Use the link to review the H’s and T’s.ulseless electrical activity usually has an underlying treatable cause. The most common cause in emergency situations is hypovolemia.

- Essentially, this type of electrical stimulation employs what is referred to as a medium frequency alternating current (in the low kHz range-thousands of cycles a second), which is delivered in a pulsed (or burst or interrupted) output.

Electrocardiogram The monitoring of pulse and blood pressure evaluates only the mechanical activity of the heart. The electrocardiogram (ECG), a noninvasive study, measures the electrical currents or impulses that the heart generates during a cardiac cycle (see figure of a normal ECG at end of monograph).

Bradycardia Bradycardia is a slow heart rate, when the heart beats less than 60 beats per minute. In some patients, who are otherwise healthy, the heartbeat may slow to less than 60 beats per minute while resting or sleeping. This usually causes no symptoms and does not require treatment.

Electrodermal activity Electrodermal activity. Electrodermal activity (EDA), is the property of the human body that causes continuous variation in the electrical characteristics of the skin.

- The apical pulse is a measure of cardiac function that is completed by placing a stethoscope at the apex of the heart and counting for one minute. It represents the opening and closing of the valves in the heart. Lub dub are the two sounds heard that make up one heartbeat.

Pulse Pulse (or the count of arterial pulse per minute) is equivalent to measuring the heart rate. The heart rate can also be measured by listening to the heart beat directly (auscultation), traditionally using a stethoscope and counting it for a minute. The radial pulse is commonly measured using three fingers.

Asystole and Pulseless electrical activity Asystole is a cardiac arrest rhythm in which there is no discernible electrical activity on the ECG monitor. Asystole is sometimes referred to as a “flat line.”. Pulseless electrical activity (PEA) is a clinical condition characterized by unresponsiveness and no palpable pulse but with some organized cardiac electrical activity.

- pulse 1. (pŭls) n. 1. The rhythmical throbbing of arteries produced by the regular contractions of the heart, especially as palpated at the wrist or in the neck. 2. a. A regular or rhythmical beating.

What is the difference between a pulse and a wave? A pulse is just a special type of wave - a solitary wave. And solitary waves that dissipate a minor amount of energy into the medium, have low dispersion, and are able to maintain their shape over distance are called 'solitons'. A vortex ring is a good and interesting example of a solition.

- Electrical impulses allow neurons to communicate with one another. During a seizure, there is abnormal and excessive electrical activity in the brain. This can cause changes in awareness, behavior, and/or abnormal movements. This activity usually lasts only a few seconds to minutes. Epilepsy refers to a condition in which a person has a risk of recurring epileptic seizures.

Pulseless Electrical Activity Treatment & Management Consultations. Once the cause of pulseless electrical activity (PEA) is identified and the patient's condition is stabilized, consultation with appropriate services may be obtained.A cardiothoracic surgery consult may be appropriate for a pulmonary embolectomy in patients with a large pulmonary embolus.nce the cause of pulseless electrical activity (PEA) is identified and the patient's condition is stabilized, consultation with appropriate services may be obtained.

What Is a Dangerously Low Pulse Rate? A pulse rate is considered dangerously low when it causes insufficient blood flow to the brain, with symptoms such as fatigue, dizziness, fainting or cardiac arrest. As the American Heart Association notes, the condition is defined as bradycardia. Continue Reading.

What is Pulseless Electrical Activity (PEA)? A patient in PEA will be completely unconscious. When the monitor is attached, you will see a rhythm on the monitor. Normal sinus rhythm, bradycardia, and ventricular tachycardia are possible rhythms that you might see. Despite having a rhythm on the monitor, the patient will not have a palpable pulse or blood pressure.

Pulseless Electrical Activity In a situation of cardiac arrest, the presence of organized ventricular electrical activity is not necessarily accompanied by meaningful ventricular mechanical activity. The qualifier “meaningful” is used to describe a degree of ventricular mechanical activity that is sufficient to generate a palpable pulse.

Question: Homeostasis and Negative Feedback Laboratory Exercise.  Before beginning this laboratory exercise... The resting cardiac rate or pulse rate, measured in beats per minute, is maintained in a state of dynamic constancy by negative feedback loops initiated by sensors in response to changes in blood pressure and other factors.herefore, the resting pulse rate is not absolutely constant but instead varies about a set-point value. This exercise will demonstrate that your pulse rate is in a state of dynamic constancy (implying negative feedback controls).

- Electromagnetic pulse. An electromagnetic pulse (EMP), also sometimes called a transient electromagnetic disturbance, is a short burst of electromagnetic energy. Such a pulse's origination may be a natural occurrence or man-made and can occur as a radiated, electric, or magnetic field or a conducted electric current, depending on the source.

Pulse oximetry Pulse oximetry is a non-invasive method for monitoring a person's O 2 saturation. In its most common (transmissive) application mode, a sensor device is placed on a thin part of the patient's body, usually a fingertip or earlobe, or in the case of an infant, across a foot. pulse oximeter is a medical device that indirectly monitors the oxygen saturation of a patient's blood (as opposed to measuring oxygen saturation directly through a blood sample) and changes in blood volume in the skin, producing a photoplethysmogram.
