Card Set Information
What land marks do you look for when you want to auscultate?
- apex of the lung
- lowest extent of the lung (diaphragm)- ant, lat, post
- lowest extent of the pleura posteriorally
- horizontal fissure
- oblique fissure (posterioraly)
- tracheal bifurcation (carina)
Information about normal breath sounds (vesicular)?
- loudest @ topof lungs- bronchial breath sounds at trachea
- air entry- air move in/ out
- BS- what you hear with stethoscpe- adipose tissue may prevent you from hearing properly
- when aus- talk about BS- good lungs = L= R, no added
Bronchial breath sounds (bronchovesicular)- BBS
- load over trachea
- quiet at the base
- but if there is a mass you will hear BBS at base
Reduce or decreased BS?
- know it is decreased by comparing to the otherside
- anything fluid like will cause decrease BS
What are the added sounds could be heard?
- crackles (crepitations, rales)
- wheeze (rhonchi)
- sputum- coasre cracklings esp in larger airwats
- equalisation of pressure- means alveoli are popping open and closed
- results of narrowing of airways
- hearing a wheeze on expiration- as itis passive and everything is closing down
: BS reduceded throughout, exp wheeze added or reduced
Other noises heard during auscultation
- pleural rub- hair near ear sounds, usually pleural inflam
- pericardial rub- creaky gate
- upper respiratory tract noises- gurgles
- extrapulmonary noise- # rib- popping noise
Technique of auscultation- Pt position
- ideal sitting with feet supported
- if someone is lying down- depress the bed and slide under to get to the back of their lungs
Where do children usually have patholgy?
- in the upper lobe
What are the parts of the stethoscpe?
- ear budon
SEE notes as to where to put the stethoscope to listen to the different parts of the lobe
When conduction ausculatation what do you get the pt to do?
- pt to do a cycle of DB
- compare sides
