Lungs and thorax Flashcards
acute cough lasts
2-3 weeks
chronic cough lasts
more than 2 months
a cough continous throughout the day may indicate
acute illness (respiratory infection)
a cough occuring in the afternoon/evenings may indicate
exposure to irritants at work
a cough present at night may indicate
postnasal drip, sinusitis
a cough present in the early morning may indicate
chronic broncial inflammation of smokers
chronic bronchitis is characterized by
a history of a productive cough for 3 months of the year for 2 years
white or clear sputum is indicative of
colds, bronchitis, viral infections
yellow or green sputum is indicative of
bacterial infections
rust colored sputum is indicative of
tuberculosis, pneumococcal pneumonia
pink frothy sputum is indicative of
pulmonary edema, so sympathomimetic medications
hacking cough is indicative of
mycoplasma pneumonia
dry cough is indicative of
early heart failure
barking cough is indicative of
croup
congested cough is indicative of
cold, bronchitis, pneumonia
orthopnea
- difficulty breathing in the supine position
paroxysmal nocturnal dyspnea
awakening from sleep with shortness of breath and needing to be upright to achieve comfort
cyanosis
bluish color
chest pain of thoracic orgin occurs with
muscle soreness from coughing or inflammation of the pleura (pneumonia)
carbon monoxide build up causes
dizziness, headache, fatigue
sulpher dioxide build up causes
cough, congestion
Expected AP/Transverse Diameter Ration
1:2
1:1 AP/Transverse Diameter Ratio is indicative of
COPD;emphysema
the tripod position is indicative of
COPD
Reasonance
low pitched, clear, hollow sound the prodominates in healthy lung tissue in adults
hyper-resonance
low-pitched, “boom”
- too much air (emphysema, pneumothorax)
dull percussion
soft, muffled, thud
- abnormal density in the lungs
hyper-resonance is indicative of
emphysema, pneumothorax
dull percussion is indicative of
pneumonia, pleural effusion, atelectasis, tumor
barrel chest description and association
- equal anteroposterior-to-transverse ratio and horizontal ribs
- associated with normal aginf and chronic emphysema as a result of hyperinflation of the lungs
kyphosis
humpback
pectus excavatum
funnel breast
pectus carinatum
pigeon breast (outward rib cage)
tachypnea
- rapid, shallow breathing; more than 24 per minute
- response to fear, anxiety, or exercise
- causes: respiratory insufficency, pneumonia, alkalosis, and lesion in the pons
bradypnea
slow breathing. Decreased rate under 10 per minute
- cases: drug induced depression, increased intercranial pressure, diabetic coma
cheyne-stokes respirations
- alternating periods of apnea and hyperventilation
- cause: heart failure, renal failure, meningitis, drug overdose, increased intercranial pressure
hyperventilation
- increase in both rate and depth
- can cause carbon dioxide to decrease in the lungs (alkalosis)
hypoventilation
- irregular, shallow pattern casued by overdose of narcotics or anaesthetics
biots respirations
- alternating periods of apnea and hyperventilation at irregular periods
fine crackles
- discontinuous, high pitched, short crackeling, pooping sounds heard
- not cleared by coughing
late inspiratory fine crackles occurs with
restrictive disease (pneumonia, heart failure, and interstinal fibrosis
early inspiratory crackles occurs with
obstructive disease (chronic bronchitis, asthma, emphysema)
posturally induced crackles
fien crackles that appear with a change of position
- occur after myocardial infraction
course crackles description
- loud, low pitched, bubbling and gurgeling sounds
- inhaled air collides with secretions in trachea and large bronchi
course crackles occur with
pulmonary edema, pneumonia, pulmonary fibrosis, depresent cough reflex
atelectatic crackles
- sound like fine crackles but do not last and are not indications of disease
- occurs in older adults, bedridden patients, and in patients that just arouse from sleep
pleural friction (description and causes)
- course and low pitched
- course gating sound
- causes: pleuritis
high pitched wheeze (description and causes)
- musical
- may be inspiratory and expiratory (prominate)
- air squeezing through narrow passageways
- Causes: acute asthma or chronic emphysema
low pitched wheezes (description and causes)
- inspiration and expiration (prominate)
- vibration in narrow airways (airflow obstruction)
- Causes: single bronchitis obstruction, tumor
stridor
- high pitched, monophonic, inspiratory, crowding sound that can be heard lower in the neck
stridor is indicative of
croup, acute epiglotis, foreign body inhalation
Acute bronchitis description
inflammation of mucous membranes of bronichial tree caused by viruses or bacteria
acute bronchitis clinical findings
- initially non-productive cough that may become productive
- substernal chest pain aggrivated by coughing
- fever, malaise, tachypnea
- rhonchi and crackles frequently heard, wheezing heard after coughing
pneumonia description
inflammation of terminal bronchioles and alveoli
pneumonia clinical manifestations
- Viral: non-productive cough or clear sputum
- Bacterial: productive cough with white, yellow, or green sputum
- fever, tachypnea, and dyspnea
- crackles and wheezing heard on auscultation
tuberculosis clinical findings
- usually initially asymptomatic; fatigue, anorexia, weight loss, fever
- later produces mucopurulent sputum
pleural effusion description
accumulation of serous fluid in pleural space between visceral and pariteal pleurae
pleural effusion findings
- dependent on the degree of fluid accumulation
- dyspnea, intercostal bulging, or decreased chest wall movement
asthma description
hyperactive airway disease characterized by bronchoconstriction, airway obstruction, and inflammation
asthma clincial findings
prolonged expiration, audiable wheeze, dyspnea, tachcardia, anxious appearance, possibility of accessory muscles, cough
- expiratory wheeze, deminished breath sounds
emphysema clinical findings
- underweight, barrel chest, short of breath with mild exertion
- wheezing and crackles on auscultation, decreased diaphragmatic excursion or percussion
closed pneumothorax
spontanous, tramatic, or iatrogenic
open pneumothorax
tramatic, iatrogenic
tension pneumothorax
developes when air leaks into the pleura and cannot escape
pneumothorax clinical findings

collapse of the lung

external pressure from tumor, fluid, or air in the pleural space
compression atelectasis
