Blood gases measure the pH (acidity), oxygen content, and carbon dioxide content of the blood. Usually, blood gases are used to analyze the arterial blood. In rarer cases, venous blood may be used.

Blood gas analysis, also called arterial blood gas (ABG) analysis, is a procedure to measure the partial pressure of oxygen (O 2 ) and carbon dioxide (CO 2 ) gases and the pH (hydrogen ion concentration) in arterial blood. Purpose Blood gas analysis is used to diagnose and evaluate respiratory diseases and conditions that influence how effectively the lungs deliver oxygen to and eliminate carbon dioxide from the blood.

Blood gas analysis, also called arterial blood gas (ABG) analysis, is a test which measures the amounts of oxygen and carbon dioxide in the blood, as well as the acidity (pH) of the blood. Purpose An ABG analysis evaluates how effectively the lungs are delivering oxygen to the blood and how efficiently they are eliminating carbon dioxide from it.

Blood gases are defined as the mixture of gases, including oxygen (O 2 ), carbon dioxide (CO 2 ), and nitrogen (N 2 ), dissolved in the fluid fraction of blood. Oxygen from the air is transported from the lungs to all tissues of the body, where it is needed for metabolism ; and carbon dioxide, a by-product of metabolism, is taken from the tissues to the lungs to be eliminated.

Electroencephalography (EEG)Electroencephalography(EEG)is a test that measures your brain wave activity. It is used to assess your brain function.What Is EEG Used For?
|
|
|
Having an Electroencephalography (EEG)TipsTry to relax and remain still.Avoid talking during the test.You will sit in a reclining chair or lie down on an exam table in a softly lighted room. The technologist will measure certain points on your head.

An electroencephalogram (EEG), also called a brain wave test, is a diagnostic test which measures the electrical activity of the brain (brain waves) using highly sensitive recording equipment attached to the scalp by fine electrodes. Purpose EEG is performed to detect abnormalities in the electrical activity of the brain which may help diagnose the presence and type of various brain disorders, to look for causes of confusion, and to evaluate head injuries, tumors, infections, degenerative diseases, and other disturbances that affect the brain.

|
Electroencephalography (EEG) is a neurological diagnostic procedure that records the changes in electrical potentials ( brain waves) in various parts of the brain. Purpose The EEG is an important aid in the diagnosis and management of epilepsy and other seizure disorders, as well as in the diagnosis of brain damage related to trauma and diseases such as strokes, tumors, encephalitis, and drug and alcohol intoxication.

|
Electroencephalography, or EEG, is a neurological test that involves attaching electrodes to the head of a person to measure and record electrical activity in the brain over time. Purpose The EEG, also known as a brain wave test, is a key tool in the diagnosis and management of epilepsy and other seizure disorders.

Electroencephalography, or EEG, is a neurological test that involves attaching electrodes to the head of a patient to measure and record electrical activity in the brain over time. Purpose The EEG, also known as a brain wave test, is a key tool in the diagnosis and management of epilepsy and other seizure disorders.
|
|
|
The electroencephalography (EEG) unit is used to record the electrical output of the brain to produce a record called an electroencephalogram. Purpose Measurements taken by an electroencephalography unit are used to diagnose and classify disorders of the brain including seizures, encephalopathy, encephalitis, some psychiatric diseases, and brain death.

An electrocardiogram (ECG) is a test that records the electrical activity of the heart. ECG is used to measure the rate and regularity of heartbeats as well as the size and position of the chambers, the presence of any damage to the heart, and the effects of drugs or devices used to regulate the heart (such as a pacemaker). See also stress test and Holter monitor (24h) .
|
|
The electrocardiogram (ECG) displays important information about the heart, including the occurrence of a heart attack or lack of oxygen, whether conduction of the heartbeat is disturbed, or its rate or rhythm altered. It is useful as a rapid indicator of the diagnosis and it is easy, painless, and inexpensive to record.
|
|
Electrocardiography is a commonly used, noninvasive procedure for recording electrical changes in the heart. The record, which is called an electrocardiogram (ECG or EKG), shows the series of waves that relate to the electrical impulses that occur during each beat of the heart.
|
|
|
The ECG (also known as EKG) is a test that records electrical signals from your heart onto a paper strip. The pattern of these signals can tell the doctor whether your heart is normal, under stress, or experiencing electrical problems, strain, or damage.
