Thorax and Lungs Flashcards
Asthma
- causes SOB, noctural cough
- often assoc with history of allergies
- can be made worse by exercise or irritants like smoke in a bar
- on auscultation there can be normal to decreased air movement
- wheezing heard on expiration (sometimes inspiration)
- with severe asthma may not hear wheezing because of lack of air movement
Pneumonia
- usually associated with dyspnea, cough and fever
- on auscultation there can be coarse or fine crackles heard over the affected lobe
- percussion over the affected area is dull and there is often an increase in fremitus
- egophony and pectoriloquy are heard because of increased transmission of high-pitched components of sounds
Spontaneous pneumothoraz
- occurs suddenly
- severe dyspnea and chest pain on affected side
- more common in young males
- on auscultation of affected side there will be no breath sounds
- on percussion there is hyperresonance or tympany
- absense of fremitus to palpation
COPD
- insidious in onset
- generally affects older populations with a smoking history
- diameter of chest if often enlarged like a barrel
- percussing chest elicits hyperresonance
- auscultation there are distant breath sounds
- coarse sounds of rhonchi are also often heard
- IMPT to quantify patient’s exercise capacity- may affect employment and allows to follow for progession of disease
Pericarditis
- pain sharp, knifelike
- located over left side of chest
- change of position, breathing and coughing often make the pain worse
- leaning forward improves the pain
- oftern seen in rheumatologic disease such as systemic lupus and in patients with chronic kidney disease
- may experience after MI
angina
- dull chest pain in retrosternal area or anterior chest
- often radiates to shoulders, arms, neck and jaw
- associated with SOB, N and sweating
- pain generally relieved by rest or medication after several minutes
Dissecting aortic aneurysm
-associated with a ripping or tearing sensation that radiates to the neck, back or abdomen
-because blood supply to the brain and extremities is disrupted, syncope and paraplegia or hemiplegia can occur
-bp will usually be different between the 2 arms
-carotid pulses often show asymmetry
(because aneurysm decreases flow distally and causes inequality of flow between sides
Pleural pain
- sharp, knifelike
- occurs over affected area of pleura
- breathing deeply usually makes the pain worse
- lying quietly on affected side make the pain better
- pleurisy often occurs from inflammation due to an infection, neoplasm or autoimmune disesse
left-sided heart failure
- fluid starts “backing up” into lungs because heart is unable to handle the volume
- xs fluid collects in dependent areas, causing crackle in bases of lower lobes
- sitting up allows patients to breathe easier
- 2 main causes: chronic high bp, and CAD, which lead to MI and decreased contractility of the heart
funnel chest
- causes by a depression in the lower portion of the sternum
- severe enough can be compression of heart and great vessels,leading to murmurs on asuculation
- usually only a cosmetic problem, corrective surgery can be performed if necessary
2nd intercostal space
location of needle insertion for tension pneumothorax
T4
approximate bifurcation of trachea
-marks inferior limit for endotracheal tube on chest x-ray
Sternal angles
- marks the 2nd rib,which helps establish the 2nd interspace for needle insertion or
- locations for cardiac auscultation (aortic and pulmonary areas)
4th intercostal space
normally used to chest tube insertion
When percussing, large pneuomthorax produces what sound
- hyperresonant
- great deal of air in the chest with a large pneumothorax, producing a hyperresonant note
