Glossary of Medical Terms. If you know of any others, please let me know so that they can be added.

ABG: Arterial blood gases. A test where blood is drawn and measured for oxygen content. The ABG tells the physician whether or not the patient is getting enough oxygen into the bloodstream. An ABG is frequently used for cases of asthma, COPD, or chest trauma.

Adenosine: A drug used to treat certain heart arrhythmias (irregular heartbeats) by helping to stabilize heart rhythm. (see IV push)

AMA: Against Medical Advice. a term used with a patient who checks himself out of a hospital against the advice of a person's doctor. While it may not be medically wise for the person to leave early, in most cases the wishes of the patient are considered first. The patient is usually asked to sign a form stating that he is aware that he or she is leaving the facility against medical advice, and the AMA term is used on reports concerning the patient. This is for legal reasons in case there are complications to limit liability on the part of the medical facility.

GSW: Gun shot wound.

Haematuria: blood in urine

Hemorrhage: a dramatic and sudden loss of blood.

Hyperkalemia: is an elevated blood level (above 5.0 mmol/L) of the electrolyte potassium . The prefix hyper- means high (contrast with hypo-, meaning low). The middle kal refers to kalium, which is Latin for potassium. The end portion of the word, -emia, means "in the blood". Extreme degrees of hyperkalemia are considered a medical emergency due to the risk of potentially fatal arrhythmias.

Hyperresonant: When percussing (thumping) a patient's back and listening for breath sounds, the doctor will hear hyperresonant, or increased, vibrations that are indicative of a pneumothorax. (see tension pneumo)

Hypertension: High blood pressure.

Hypotension: Low blood pressure.

Influenza : means flu in latin.

Intubation: the procedure of inserting a tube into the trachea of a patient who is not breathing.

Intubation tray: A tray that contains various instruments used to intubate a patient who is not breathing: a laryngoscope, which is an instrument for opening the larynx; and an endotracheal tube, which is inserted into the trachea through the mouth to facilitate breathing. A bag is attached outside the mouth so that breathing can be done mechanically for the patient - in a procedure known as "bagging."

IV push: When a drug is put directly into the IV all at once.

Large-bore IV: An IV with a large needle used to transfuse fluids - either saline or blood - very quickly, particularly in trauma cases, where a patient may have lost a lot of blood.

Laryngoscope: an instrument for opening the larynx.
