aphonia
the loss of the ability of the larynx to produce normal speech sounds
asbestosis
caused by asbestos particles in the lungs and usually occurs after working with asbestos
asphyxia
is the loss of consciousness that occurs when the body cannot get the oxygen it needs to function.
asthma
a chronic inflammatory disease of the bronchial tubes, often triggered by an allergic reaction.
atelectasis
or collapsed lung, is the incomplete expansion of part or all of a lung due to a blockage of the air passages or pneumothorax
bradypnea
an abnormally slow rate of respiration, usually of less than 10 breaths per minute
bronchiectasis
the permanent thickening of the walls of the bronchi, caused by chronic infection and inflammation
bronchodilator
is an inhaled medication that relaxes and expands the bronchial passages into the lungs.
bronchorrhea
an excessive discharge of watery mucus from the bronchi
bronchoscopy
the visual examination of the bronchi using a bronchoscope
bronchospasm
is a contraction of the smooth muscle in the walls of the bronchi and bronchioles, tightening and squeezing the airway shut
Cheyne-Stokes respiration
an irregular pattern of breathing characterized by alternating rapid or shallow respiration followed by slower respiration or apnea
chronic obstructive pulmonary disease (COPD)
a group of lung diseases in which the bronchial airflow is obstructed, making it difficult to breathe out
croup
an acute respiratory infection in
children and infants characterized by obstruction of the larynx, hoarseness, and swelling around the vocal cords resulting in a barking cough and stridor.
cyanosis
a bluish discoloration of the skin and mucous membranes caused by a lack of adequate oxygen in the blood
cystic fibrosis

dysphonia
difficulty in speaking, which may include any impairment in vocal quality, including hoarseness, weakness, or the cracking of a boy’s voice during puberty
dyspnea
also known as shortness of breath, difficult or labored breathing
emphysema
the progressive, long-term loss of lung function, usually due to smoking. Emphysema is characterized by a decrease in the total number of alveoli, enlargement of the remaining alveoli, and the progressive destruction of the walls of these
remaining alveoli.
empyema
refers to a collection of pus in any body cavity.
endotracheal intubation
the passage of a tube through the mouth into the trachea to establish or maintain an open airway, especially when a patient must be placed on a ventilator
