A complete medical history taken by a health care practitioner is the most important diagnostic tool. Often, a survey that asks a series of questions about daytime sleepiness, sleep quality, and bedtime habits is given. A physical examination of t...

Sleep apnea is a condition in which breathing stops for more than ten seconds during sleep. Sleep apnea is a major, though often unrecognized, cause of daytime sleepiness. It can have serious negative effects on a person's quality of life, and is ...

Sleep apnea, or sleep-disordered breathing, is a condition in which breathing is briefly interrupted or even stops episodically during sleep. Because repeated arousal or even full awakening when breathing stops disturbs sleep, individuals sufferin...

Blood gases is a test done to measure how much oxygen and carbon dioxide is in your blood. It also looks at the acidity (pH) of the blood. Usually, blood gases look at blood from an artery. In rarer cases, blood from a vein 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.

Polysomnography is a sleep study. It measures your sleep cycles and stages by recording brain waves (EEG), electrical activity of muscles, eye movement, breathing rate, blood pressure, blood oxygen saturation, and heart rhythm. A specially trained health care provider will directly observe you while you sleep. There are two states of sleep: non-rapid eye movement (NREM) sleep and rapid eye movement (REM) sleep. REM sleep is associated with dreaming. Your body muscles (except your eyes and lungs) do not move during this stage of sleep. NREM sleep has four stages distinguishable by EEG waves. REM sleep alternates with NREM sleep approximately every 90 minutes. A person with normal sleep usually has four to five cycles of REM and NREM sleep during a night.

The word polysomnography, derived from the Greek roots " poly, " meaning many, " somno, " meaning sleep, and " graphy " meaning to write, refers to multiple tests performed on patients while they sleep. Polysomnography is an overnight test to evaluate sleep disorders .

What Is a Sleep Study?Do you often have problems sleeping?
|
 |
Polysomnography is a series of tests performed on patients while they sleep. Polysomnography is a comprehensive overnight procedure that evaluates sleep disorders .
|
 |
Polysomnography is a set of tests performed while a patient sleeps. It is done to diagnose and evaluate sleep disorders , and examines at a minimum brain wave patterns, the movements of both eyes, and the tone of at least one skeletal muscle.
|
|
During a physical examination, a health care provider studies a patient's body to determine the presence or absence of physical problems. A typical physical examination includes: Inspection (looking at the body; Palpation (feeling the body with hands; Auscultation (listening to sounds; Percussion (producing sounds.

Pulmonary function tests are a group of tests that measure how well the lungs take in and release air and how well they move oxygen into the blood.
|
 |
Pulmonary function tests are a group of procedures that measure the function of the lungs, revealing problems in the way a patient breathes. The tests can determine the cause of shortness of breath and may help confirm lung diseases, such as asthma , bronchitis or emphysema .
|
|
A pulmonary function test shows how well your lungs are working. A complete test has three parts. You may be given the entire test or only certain parts. The entire test is painless and lasts 45–90 minutes.
|
|
Pulmonary function tests are a group of procedures that measure how well the lungs are functioning. Purpose Pulmonary function tests help a doctor to diagnose respiratory diseases and disorders such as asthma , chronic obstructive pulmonary disease (COPD), and emphysema, and mechanical injury by measuring the degree of lung impairment.

Normal individuals have a large reserve in lung function that allows breathing capacity to increase at least twenty to thirty times during periods of vigorous physical activity. It is not the ability to breathe that normally limits maximum exercise capability, nor does physical activity normally change lung function, either in the short-term or over time with training.

The pulse oximeter is a photoelectric instrument for measuring oxygen saturation of the blood . A pulse oximeter uses infrared light and a photo sensor to detect the amount of oxygen in a patient's blood.
|
|
The pulse oximeter is a photoelectric instrument for measuring oxygen saturation of blood. Purpose A pulse oximeter measures the amount of oxygen present in blood by registering pulsations within an arteriolar bed (an area between arteries and capillaries).

T4 (thyroxine) is a hormone produced by the thyroid gland. A laboratory test can be done to measures the amount of the T4 in your blood.
|
 |
TSH is a laboratory test that measures the amount of thyroid stimulating hormone (TSH) in your blood. TSH is produced by the pituitary gland and tells the thyroid gland to make and release the hormones thyroxine (T4) and triiodothyronine (T3. See also: T3 test; T4 test.
|
 |
Thyroid function tests are common tests used to tell how well your thyroid is working. See the following articles for details: T3; T3 resin uptake; T4; Thyroid scan; TSH; TSI.
|
|
Thyroid function tests are blood tests used to evaluate how effectively the thyroid gland is working. These tests include the thyroid-stimulating hormone test (TSH), the thyroxine test (T 4 ), the triiodothyronine test (T 3 ), the thyroxine-binding globulin test (TBG), the triiodothyro-nine resin uptake test (T 3 RU), and the long-acting thyroid stimulator test (LATS).

Detailed information on the most common types of thyroid function tests
|
|
Thyroid function tests are blood tests used to evaluate how effectively the thyroid gland is working. These tests include the thyroid-stimulating hormone test (TSH), free and total thyroxine tests (FT 4 ,T 4 ), the free and total triiodothyronine tests (FT 3 ,T 3 ), the thyroxine-binding globulin test (TBG), and the T-uptake test.
|
|
The key tests to determine thyroid function are serum measurements of free thyroid hormones and thyroid-stimulating hormone (TSH). Thyroid hormones have a negative feedback on TSH secretion from the anterior pituitary.
