Chapter 19 Flashcards
Alveoli
Functional unit of the lung
Thing-walled chambers surrounded by networks of capillaries that are the site of respiratory exchange of CO2 and 02
Angle of Louis
Manubriosternal angle, the articulation of the manubrium and body of the sternum, continuous with the second rib
Apnea
Cessation of breathing
Asthma
An abnormal respiratory condition associated with allergic hypersensitivity to certain inhaled allergens
Characterized by: Inflammation, bronchospasm, wheezing, and dyspnea
Atelectasis
An abnormal respiratory condition characterized by collapsed, shrunken, deflated sections of alveoli
Bradypnea
Slow breathing, fewer than 10 breaths per minutes
Bronchiole
On of the smaller respiratory passageways into which the segmental bronchi divide
Bronchitis
Inflammation of the bronchi with partial obstruction of bronchi due to excessive mucus secretion
Bronchophony
The spoken voice sound heard through the stethoscope, which sounds soft, muffled, and indistinct over normal lung tissue
Bronchovesicular
The normal breath sound heard over major bronchi
Characterized by: Moderate pitch, an equal duration of inspiration and expiration
Chronic obstructive pulmonary disease (COPD)
A functional category of abnormal respiratory conditions
Characterized by: Airflow obstruction
Cilia
Millions of hairlike cells lining the tracheobronchial tree
Consolidation
The solidification of portions of lung tissue as it fills up with infectious exudate
Ex. pneumonia
Crackles (Rales)
Abnormal, discontinuous, adventitious lung sounds heard on inspiration
Dead space
Passageways that transport air but are not available for gaseous exchange
Ex. Trachea, bronchi
Dyspnea
Difficult, labored breathing
Emphysema
Chronic obstructive pulmonary disease
Characterized by: Enlargement of alveoli distal to terminal bronchioles
Fissure
The narrow crack dividing the lobes of the lungs
Fremitus
A palpable vibration from the spoken voice felt over the chest wall
Friction rub
A coarse, grating, adventitious lung sound heard when the pleurae are inflamed
Hypercapnia
Increased levels of CO2 in the blood
Hyperventilation
Increased rate and depth of breathing
Hypoxemia
Decreased level of oxygen in the blood
Intercostal Space
Space between the ribs
Kussmaul Respiration
type of hyperventilation that occurs with diabetic ketoacidosis
Orthopnea
Ability to breathe easily only in an upright position
Paroxysmal Nocturnal Dyspnea
Sudden awakening from sleeping, with shortness of breath
Percussion
Striking over the chest wall with short, sharp blows of the fingers to determine the size and density of the underlying organ
Pleural Effusion
Abnormal fluid between the layers of the pleura
Rhonchi
Low-pitch, musical, snoring, adventitious lung sounds caused by obstruction from secretions
Tachypnea
Rapid, shallow breathing
More than 24 breaths per minute
Vesicular
Refers to soft, low-pitched, normal breath sounds heard over peripheral lung feilds
Wheeze
High-pitched, musical, squeaking adventitious lung sounds
Xiphoid process
Sword-shaped lower top of the sternum
What subjective thing would you ask about when assessing?
Cough Chest pain Respiratory infections Smoking Shortness of breath Environmental exposure
Pleura
Thing slippery serous membrane between chest wall and lungs
What structures are composed of dead space?
Trachea
Bronchi
What elements would you include in inspection of respiratory system?
Shape and configuration
Color
Respiration rate
Use of accessory muscles
What characteristics define barrel chest?
Costal angle >90
Appears as if in continuous inspiration
Hyperinflation of the lungs
What condition is barrel chest most common in?
COPD
Bronchial lung sound
High-pitch
Inspiration < expiration
Harsh, hollow, tubular
Trachea and larynx
Bronchovesicular lung sound
Moderate pitch
Inspiration = expiration
Over major bronchioles
Vesicular lung sounds
Low pitch
Inspiration > expiration
Rustling sound
Peripheral lung fields
The manubriosternal angle is also called ___
Angle of Louis
What is a normal costal angle?
90 degrees
Anteroposterior/ Tranverse diameter ratio
2:1
