Temperature
The degree of hotness or coldness of a body or enviornment (Corresponding to its molecular activity)
Turgor
the normal rigid state of fullness of a cell or blood vessel or capillary resulting from pressure of the contents against the wall or membrane
Vital Signs
Body temperature, pulse, respiration, and blood pressure. Many agencies have designated pain as the fifth vital sign
Adventitious breath sounds
Abnormal breath sounds that occur when air passes through narrowed airways or airways filled with fluid or mucus, or when pleural linings are inflamed
Alveoli
Thin-walled microscopic air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place
Apnea
A complete absense of respirations
Atelectasis
Collapse of the air sacs
Auscultation
The process of listening to sounds produced within the body, such as with the use of a stethoscope that amplifies sounds and conveys them to the nurse’s ears
Bradypnea
Abnormally slow respiratory rate, usually less than 10 respirations per minute
Cheyne-Stokes respirations
Rhythmic waxing and waning of respirations from very deep breathing to very shallow breathing with periods of temporary apnea, often associated with cardiac failure, increased intracranial pressure, or brain damage
Crackles
Fine crackling or bubbling sound heard on inspiration, fluid in alveoli or opening of closed alveoli
Diffusion
The mixing of molecules or ions of two or more sustances as a result of random motion
Dyspnea
Difficult or labored breathing
Exhalation
Breathing out, or the movement of gases from the lungs to the atmosphere
Eupnea
Normal, quiet breathing
Expiration
The outflow of air from the lungs to the atmosphere
Gurgles
AKA rhonchi, low pitched, bubbling heard in larger airways. More prominent during expiration. Sounds like wet snoring. May clear with deep breathing or coughing
Hemoptysis
The presence of blood in the sputum
Hyperpnea
Energetic (deep and rapid) respiration that occurs normally after exercise or abnormally with fever or various disorders
Hyperventilation
Very deep, rapid respirations
Hypoventilation
Very shallow respirations
Hypoxia
Insufficient oxygen anywhere in the body
Hypoxemia
Low partial pressure of oxygen or low saturation of oxyhemoglobin in the arterial blood
Inspiration
The intake of air into the lungs
Kussmaul’s Respirations
Hyperventilation that accompanies metabolic acidosis in which the body attempts to compensate (give off excess body acids) by blowing off carbon dioxide through deep and rapid breathing
Nonproductive Cough
A dry, harsh cough without secretions
Orthopnea
Ability to breath only when in an upright position (sitting or standing)
Percussion
A method of which the body surface is struck to elicit sounds that can be heard or vibrations that can be felt
Pleural Friction Rub
Creaking or grating sound from roughened, inflamed surfaces or the pleura rubbing together, evident during inspiration, expiration, or both and no change with coughing; usually uncomfortable, especially on deep inspiration
Productive Cough
Cough that expectorates mucous secretions from the respiratory tract
Pulse Oximetry
A noninvasive device that measures the arterial blood oxygen saturation by means of a sensor attached to the finger or other location
Rales
Bubbling or noisy sounds caused by fluids or mucus in the air passages
Respiration
The act of breathing; includes the intake of oxygen and the output of carbon dioxide from the cells to the atmosphere
Rhonchi
Lower-pitched sounds like snoring or rattling, secretions in larger airways (pneumonia, bronchitis, aspiration)
Tachypnea
Abnorally fast respirations; usually more than 24 respirations per minute
Ventilation
The movement of air in and out of the lungs; the process of inhalation and exhalation

These are eye movements controlled by several pairs of eye musscles. During the assessment, both eyes should move in a coordinated manner. No movement in one may indicate neurologic pathology
