Head & Neck The HEENT, or Head, Eye, Ear, Nose & Throat Exam is usually the initial part of a general physical exam, after the vital signs Like other parts of the physical exam, it begins with inspection, & then proceeds to palpation It requires the use of several special instruments in order to inspect the eyes & ears, & special techniques to assess their special sensory function 3
Head & Neck 4
Head & Neck Skull Hair Scalp & Face Neck Nose Ears Hearing Mouth & Pharynx Eyes 5
Head & Neck
Inspection
Inspect the skull for size, shape & evidence of trauma
Palpation
Palpate the skull for lumps, bumps & evidence of trauma 6
Head & Neck
Inspection
Inspect for quantity& distribution
Palpation

Head & Neck
Simple
Assess the ability of the patient to hear a sequence of equally accented words/numbers (3-5-2-4) whispered from a distance of a couple of feet 14
Head & Neck
Rinne Test
Compares bone & air conduction Place tip of vibrating tuning fork on the mastoid process behind the ear Ask the patient to indicate when he no longer hears the vibrating turning fork Hold the fork in front but not touching the ear canal to test air conduction Normally patient can hear vibration better than feeling them 15

Equipment needed Inspection Palpation Percussion Auscultation Pulmonary Function Test (Spirometry) 27
Stethoscope Peak flow meter 28
Observe the rate, rhythm, depth, & effort of breathing. Note whether the expiratory phase is prolonged Listen for obvious abnormal sounds with breathing such as wheezes Observe for retractions & use of accessory muscles (abdominals) Observe the chest for asymmetry, deformity, or increased anterior-posterior (AP) diameter Confirm that the trachea is near the midline 29
Identify any areas of tenderness or deformity by palpating the ribs & sternum Assess expansion & symmetry of the chest by placing your hands on the patient's back, thumbs together at the midline, & ask them to breath deeply 30
Percuss over intercostal spaces to assess lung density 31

Percussion Notes & Their Meaning
Flat or Dull Pleural Effusion or Pneumonia Normal Hyperresonant Healthy Lung or Bronchitis Emphysema or Pneumothorax 34
Breath Sounds
Using a stethoscope Instruct patient to breath deeply & slowly Use a systematic approach, compare each side to the other, document when & where sounds are heard Normal breath sounds: tracheal, bronchovesicular, bronchial, & vesicular 35
Breath Sounds: Normal Sounds
Trachea: tracheal Large central bronchi: bronchovesicular Small airways distal to central bronchi: bronchial Small lateral airways: vesicular 36
Breath Sounds: Abnormal Sounds
Wheeze
- may be heard with or without stethoscope high-pitched squeaky musical sound; usually not changed by coughing; Document if heard on inspiration, expiration, or both Noise is caused by air moving through narrowed or partially obstructed airway Heard in asthma 37
Breath Sounds: Abnormal Sounds
Stridor
- may be heard without stethoscope, shrill harsh sound on inspiration ; is an inspiratory wheeze associated with upper airway obstruction (croup) Laryngeal obstruction 38
Breath Sounds: Abnormal Sounds
Crackles
- heard only with stethoscope (rales): These are high pitched, discontinuous sounds similar to the sound produced by rubbing your hair between your fingers May clear with cough Most commonly heard in bases; easier to hear on inspiration (but occurs in both inspiration & expiration) 39
Breath Sounds: Abnormal Sounds
Gurgles
- heard only with stethoscope (rhonchi): Low pitched, coarse wheezy or whistling sound Usually more pronounced during expiration when air moves through thick secretions or narrowed airways Sounds like a moan or snore; best heard on expiration (but occur both in & out) Any extra sound that is not a crackle or a wheeze is probably a rhonchi 40
Most common of the Pulmonary Function Tests (PFTs) Measures lung function, specifically the of the amount (volume) &/or speed (flow) of air that can be inhaled & exhaled Spirometry is an important tool which can helpful in assessing conditions such as asthma, pulmonary fibrosis, cystic fibrosis, & COPD It can be used as a baseline or a post bronchodilator test (Post BD), & is an important part in diagnosing asthma versus COPD 41

Abbreviation
FVC
Name Description
Forced Vital Capacity The volume of air that can forcibly be blown out after full inspiration, measured in liters FEV 1 Forced Expiratory Volume in 1 Second The maximum volume of air that can forcibly blow out in the first second during the FVC, measured in liters. Along with FVC it is considered one of the primary indicators of lung function 43
Abbreviation
FEV 1 /FVC
Name
FEV1%
Description
• The ratio of FEV 1 to FVC •
Normal:
75–80% •
In obstructive diseases
value (<80%, often ~45%) (asthma, COPD, chronic bronchitis, emphysema) FEV 1 is diminished because of increased airway resistance to expiratory flow and the FVC may be increased this generates a reduced •
In restrictive diseases
(such as pulmonary fibrosis) the FEV 1 & FVC are both reduced proportionally & the value may be normal or even increased 44
Abbreviation Name Description
PEF FEF 25–75% or 25–50% Peak Expiratory Flow Forced Expiratory Flow 25– 75% or 25– 50% The maximal flow (or speed) achieved during the maximally forced expiration initiated at full inspiration, measured in liters/second • The average flow (or speed) of air coming out of the lung during the middle portion of the expiration (also sometimes referred to as the MMEF, for maximal mid-expiratory flow) •
In small airway diseases
expected value such as asthma this value will be reduced, perhaps <65% of • This may be the first sign of small airway disease detectable 45
Abbreviation Name Description
FIF 25–75% or 25–50% Forced Inspiratory Flow 25– 75% or 25– 50% This is similar to FEF 25–75% or 25–50% except the measurement is taken during inspiration FET Forced Expiratory Time This measures the length of the expiration in seconds 46

Inspection Palpation Auscultation (Heart Sounds) 49
Chest for visible cardiac motion Estimate Jugular Venous Pressure (JVP) Patient supine & head elevated to 15-30 degrees JVP is the distance b/w highest point at which pulsation can be seen & the sternal angle 50
JVP
51
JVP
An indirect measure of right atrial pressure Measured in centimeters from the sternal angle & is best visualized with the patient's head rotated to the left Described for its quality & character, effects of respiration, & patient position-induced changes 52
53
Physical Landmarks
Suprasternal notch Sternum Manubriosternal angle – Angle of Louis Intercostals Spaces 54
Palpate for (Point of Maximal Impulses) PMI; easiest if patient sits up & leans forward Has a diameter of ≈ 2cm & located with 10 cm of the midsternal line Palpate for general cardiac motion with fingertips and patient in supine position Palpate for radial, carotid, brachial, femoral & other peripheral pulses 55
See figure 4-12 for peripheral pulses 56
With a stethoscope Use diaphragm to assess higher pitched sounds Needs a lot of practice & experience Listen in a quiet area or to close eyes to reduce conflicting stimuli See also figure 4-10 for auscultatory Sites 57
58
59
The auscultatory Sites are close to but not the same as the anatomic locations of the valves Aortic area 2 nd ICS at the right sternal border Pulmonic 2 nd ICS at the left sternal border Tricuspid lt lower sternal border Mitral cardiac apex 60
Heart sounds are characterized by location, pitch, intensity, duration, & timing within the cardiac cycle 61
High-pitched sounds such as S 1 & S aortic & mitral regurgitation, & pericardial friction rubs are best heard with the diaphragm 2 , murmurs of The bell is preferred for low-pitched sounds such as S 3 & S 4 62
S1: Closure of AV valves (mitral and tricuspid valves: M1 before T1) Correlates with the carotid pulse Loudest at the cardiac apex Can be split but not often 63
S2: Closure of Semilunar valves (aortic & pulmonic) Loudest at the base of the heart May have a split sound (A2 before P2) 64
S 1 & S 2 position assessed in all four sites in upright and supine S 1 precedes and the S 2 follows the carotid pulse 65
S3…
Due to volume overload Due to Rapid ventricular filling: ventricular gallop S1 -- S2-S3 (Ken--tuc-ky)
S4…
Due to pressure overload Due to slow ventricular contraction: atrial gallop S4-S1 — S2 (Ten-nes—see) 66
S3…
Low-pitched sound Heard at apex of the heart Caused by rapid filling & stretching of the left ventricle Characteristic of volume overloading, such as in CHF (especially left-sided heart failure), tricuspid or mitral valve insufficiency
S4…
A dull, low-pitched postsystolic atrial gallop Caused by reduced ventricular compliance Best heard at the apex in the left lateral position Present in conditions such as aortic stenosis, hypertension, cardiomyopathies, & coronary artery disease Less specific for CHF than S3 67
Turbulent blood flow across a valve or a disease such as anemia or hyperthyroidism Listen for murmurs in the same auscultatory sites APETM Systolic b/w S1 & S2 Diastolic b/w S2 & S1 68
They are classified by
Timing & duration within the cardiac cycle (systolic, diastolic, & continuous) Location Intensity Shape (configuration or pattern) Pitch (frequency) Quality, & radiation 69
