Introduction

++

abdomen the part of the body between the pelvis and the thorax.

++

abdominal splinting a rigid contraction of the muscles of the abdominal wall. It usually occurs as an unconscious reaction to abdominal pain. Abdominal splinting, in turn, may result in hypoventilation and respiratory complications.

++

acute compartment syndrome usually secondary to trauma; increasing pressure within a fascial compartment as a result of swelling or bleeding can result in nerve damage and necrosis of muscle tissue (avascular necrosis).

++

acute mountain sickness a syndrome associated with the relatively low concentrations of oxygen in the atmosphere at altitudes encountered during mountain climbing or travel in unpressurized aircraft.

++

acute stress disorder a condition that develops soon after an individual experiences or witnesses an event involving a threat of or an actual death, serious injury, or physical violation and responds to this event with strong feelings of fear, helplessness, or horror.

++

adventitious coming from an external source or occurring in an unusual place or manner. During auscultation of the chest or abdomen, adventitious sounds are those that are normally not heard.

++

agonal respirations a type of breathing that usually follows a pattern of gasping followed by apnea.

++

airway obstruction an abnormal condition of the respiratory system characterized by a mechanical impediment to the delivery or to the absorption of oxygen in the lungs.

++

airway patency the condition of an airway being open or unblocked.

++

alignment the association of long bone fracture fragments to one another; measured in degrees of angulation from the distal fragment in relation to the proximal fragment.

++

aneroid sphygmomanometer a device using air pressure to measure arterial blood pressure. Aneroid refers to the absence of liquid, in this case the absence of a mercury column in the pressure gauge.

++

aneurysm a localized weakening and swelling in the wall of a blood vessel. Can be caused by a number of factors, including hypertension, atherosclerosis, trauma, infection, or genetics.

++

angiogram an x-ray of blood vessels that can be seen because the patient receives an injection of dye to outline the vessels on the x-ray. A coronary angiogram can be used to identify the exact location and severity of coronary artery disease (CAD).

++

anterograde amnesia the inability to recall events of long ago with normal recall of recent events.

++

aortic dissection a progressive tear in the aorta. When the inner lining of the aorta tears, blood surges through the tear, creating a new false channel, separating (dissecting) the middle layer from the outer layer of the aorta.

++

aortic stenosis narrowing of the aortic valve and obstructing blood flow from the left ventricle into the aorta, resulting in decreased cardiac output.

++

apnea   an absence of spontaneous respiration.
