Heart & Lung PT Flashcards
How many lobes does the right lung have? How many fissures?
3 lobes (superior, middle, inferior)
2 fissures (horizontal and oblique)
How many lobes does the left lung have? How many fissures?
2 lobes (superior, inferior)
1 fissure (oblique)
Why does the left lung have less lobes than the right?
Due to the space taken up by the heart on the left
What instructions should you give your pt. prior to auscultation?
- sit up
- lean forward
- deep breaths
- turn your head away from me
How many areas are ausculated on the anterior, posterior, and lateral lung?
Anterior: 10 spots (5 each side)
Posterior: 12 spots (6 each side)
Laterally: 4 spots
** look at diagram
Name the following breath sound: heard over entire lung, except beneath manubrium and interscapular region
Vesicular (over lung fields)
Name the breath sound: long on inhalation, short on expiration
Vesicular (over lung fields)
Name the following breath sound: result from consolidation/compression of pulmonary tissue that assists in transmission of sound from the bronchial tree
Bronchial (tubular, over trachea)
Name the following breath sound: short on inspiration, long on expiration
Bronchial (tubular, over trachea)
** or equal on inspiration/expiration
Which breath sounds are louder?
Bronchial
Describe the pitch and intensity of vesicular and bronchial breath sounds
Vesicular: low pitch, soft intensity
Bronchial: high ptich, loud intensity
Identify the abnormal sound: coarse rattling on exhale, very clear, low pitched, due to mucus in bronchi
Rhonchi
Identify the abnormal sound: fine, noncontinuous rattling, high pitched, sound like rice crispies, heard on inhale (sometimes exhale), due to fluid in alveoli/bronchioles
Rales or Crackles
Identify the abnormal sound: muscial sounds like high pitched clarinet notes, produced on inhale, due to constriction/obstruction
Wheeze
Identify the abnormal sound: stratchy sounds produced by movement of pleural surfaces; “walking on fresh snow”
Pleural friction rub
Identify the abnormal sound: pt. says E, ausculate A
Egophony
Identify the abnormal sound: pt. says 99, you hear clear 99
Bronchophony
Identify the abnormal sound: you ausculate clear whisper
Whispering pectoriloquy
Heart sound: start of systole, AV valves close
S1, lub (low pitched)
Heart sound: end of systole, aortic/pulmonic valves close
S2, dub (loud)
Heart sound: as ventricles fill, due to vibration on ventricular wall
S3
Heart sound: at atrial contraction (atrial kick), due to accelerated rush of blood in the ventricles
S4
What causes S1?
Closure of AV valves; ventricular pressure > atrial pressure
What causes S2?
closure of aortic/pulmonic valves; due to vessel pressure > ventricular pressure
List the order of timing of S1, S2, and carotid pulse
S1, pulse, S2
T/F: S3 and S4 are normal heart sounds.
False: abnormal, seen with heart failure
Location: aortic valve
R 2nd intercostal space
Location: pulmonic valve
L 2nd intercostal space
Location: Tricuspid/Right AV valve
L 4th intercostal space
Location: Mitral/Bicuspid/Left AV valve
L 5th intercostal space
