Stethoscope Diaphragm
-high frequency sounds
Stethoscope Bell
-low frequency sounds
S1
-first heart sound (higher frequency)
-closure of M1 and T1
-best heard in Mitral Area
S2
-second heart sound (lower frequency)
-closure of semilunar valves valves
-best heard in Aortic Area
Aortic Area
-right sternal border
-2nd intercostal space
-S2 best heard
Pulmonic Area
-left sternal border
-2nd intercostal space
Tricuspid Area
-left sternal border
-4th intercostal space
Mitral Area
-left side under nipple
-apex of heart
-5th intercostal space
-S1, S3, S4 best heard
Apical Pulse
Listen to apex of heart for 1 min
S3
-could be abnormal (heart failure, late diastole) or normal (pregnancy/children)
-extra heart sound after S2
-“kenTUCKy”
-caused by rapid filling of ventricle
-listen with bell @ apex
S4
-always abnormal (HTN, MI, atrial kick of blood into stiff ventricle diastolic bad)
-right before S1
-gallop
Respiratory Cycle
Inspiration: 1/3, faster and louder
Expiration: 2/3, slower and softer
Vesicular Breath Sounds
-most of lung area
-inspiratory longer than expiatory
-soft
Brocho-Vesicular Breath Sounds
-near midline around upper spine and sternum
-inspiratory equal expiatory
Bronchial Breath Sounds
-above manubrium
-loud
-inspiratory shorter than expiatory
Lung Auscultation Areas
2 for each lobe
-anterior right (apical, upper,middle,lower(basal)),
-anterior left (apical, upper, lingua, lower(basal)
-posterior: apical, upper, superior lower, basal
Lung Ascultation Checkout Steps

Heart Ascultation Checkout
- Explain (I’m going to be usuing this stethescope to listen to your heart and see how well it’s working)

BP Steps
- Explain procedure
- Determine cuff size
- Drape appropriately
- Positions Patient Properly
- take radial pulse for 60s (deflate at 2mmHg/sec if >60 or 2mmHg/bear if <60bpm)
- Palpate radial pulse and inflate cuff until pulse disappears
- re-inflate cuff 30mmHg above previous pressure
- deflate at 2mmHg/sec if >60 or 2mmHg/beat if <60bpm
