assessment of the thorax and lungs the respiratory system
TRANSCRIPT
Health History Cough:
Productive, nonproductive Sputum
SOB Chest pain - with or without inspiration Smoker Environmental exposures Past medical hx.
Resp. illnesses, allergies, thoracic surgery Family hx.
TB, CF, Emphysema, Allergies, Asthma, Malignancy
Age Considerations
Children Hx. of colds, frequent respiratory
infections, allergies, smokers in the home
Elderly Hx. of SOB, fatigue, activity level, recent
weight changes, current medications
General Assessment Respiratory Rate Rhythm (Regular or Irregular) Use of accessory muscles Anteroposterior (AP:L) diameter [2:1] Purse lip breathing Depth of respirations (shallow or deep) Type of respirations (diaphragm or chest)
Pursed Lip Breathing
is the act of exhaling through tightly pressed, pursed lips. Doctors and respiratory therapists teach the technique to their patients to ease shortness of breath and to promote deep breathing, also referred to as abdominal or diaphragmatic breathing. The purpose of PLB is to create back-pressure inside airways to splint them open; moving air thus then takes less work.
Lips and Nails Clubbing of nails
Normal, (-) clubbing Nail angle 160° or less Abnormal, (+) clubbing Nail angle straightens to 180° or >,
spongy Color
Mucous membranes Capillary refill (< 3 sec)
Thoracic configuration
Deformities, shape and symmetry AP to Lateral diameter, 2:2, Barrel chest Pectus
Carinatum – pigeon chest, protrusion Excavatum – funnel chest, inward
Spinal deformities Intercostal spaces
Retractions (flail chest – sucking in) Bulging
Tracheal deviation – never normal
Pattern of Respirations: Men & Children
Diaphragmatic Women
Thoracic or costal Resting respiratory rate – should be
smooth and rhythmical 12 – 20 (12-25)
Tachypnea Bradypnea
Additional Respiratory Patterns Hyperventilation
Increased rate and shallow Hypoventilation
Decreased rate and shallow, irregular Cheyne-Stokes
Alternating tachypnea and apnea Biot’s respiration
Irregular pattern of normal resp. and apnea
Paroxysmal nocturnal dyspnea (PND) Awakening from sleep with SOB
Kussmaul Deep rapid and laborious
Palpation
Angle of Louis/Manubriosternal angle Articulation of the manubrium and
body of sternum It is continuous with the 2nd rib Good place to start counting ribs Marks the site of tracheal bifurcation,
and the upper border of the atria of the heart
Tenderness
Palpation Masses Thoracic expansion
Place hands over lung fields, thumbs touching With deep breath – smooth, symmetrical,
flattens
Tactile fremitus Vibration, have pt. say 99 or blue moon; should
be equal Increased – consolidation, tumors, pneumonia Decreased – pneumothorax, pleural effusion,
emphysema, atelectasis, obstruction
Percussion Percuss lung borders side to side:
Anteriorly Left – resonance to 3rd ICS, then dullness d/t
heart Right – resonance to 5th ICS, then dullness d/t
liver Posteriorly
Left –resonance to 9th ICS, then dullness d/t diaphragm
Right – resonance to 8thICS, then dullness d/t diaphragm
Auscultation
Auscultate with pt. in thesitting position. Begin at theapex and listen from side toside.
Normal Breath Sounds Vesicular
Found over lung periphery. Low pitched, soft breezy sound.
Inspiration > Expiration by 2 ½ times. Bronchovesicular
Found on either side of sternum and between scapula on back. Moderate intensity.
Inspiration = Expiration Bronchial
Found over the trachea and above manubrium. Loud, harsh, high pitched, blowing sound.
Inspiration < Expiration by ½. Absent breath sounds
Adventitous Breath Sounds - Discontinuous Crackles – indicate serous secretionsin the distal bronchioles
Fine crackles (Rales) – hi pitched,popping sound, like rubbing of hair.Heard during inspiration. Does notclear with coughing. Heard withobstructive diseases.
Coarse crackles – low pitched,crumpling cellophane paper sound.Heard throughoutinspiration, maybeexpiration Heard with pneumonia,CF,pulmonary edema
Pleural Friction Rub – heard in lower part of chest,
anterolateral surface. Coarse rubbing or grating sound.
Does not clear with coughing.
Pleuritis
Adventitious Breath Sounds - Continuous Wheezes
Sibilant (rhonchi) – hi pitched,musical. Heard during inspiration,but most often during expiration d/t bronchospasm. Heard with asthma,emphysema, and other obstructive lung dx. Sonorous (rhonchi) – low pitched,snoring sound. Clears with coughing. Commonly heard during expiration.D/t partial obstruction from secretions, tumor, bronchitis.
Stridor Hi pitched, crowing sound. Heard withcroup, obstructed airway
Documentation
Document adventitious breath sounds for: Frequency Timing Location Effect of position change
Vocal Fremitus/Resonance Bronchophony
Auscultate posterior chest. 99 should be soft and muffled, if loud and clear, consider lung consolidation.
Egophony Evaluates intensity of spoken voice. Have pt. say
eee, should hear soft, muffled eee, if aaa heard, consider lung consolidation.
Whispered Pectoriloquy Performed when a (+) bronchophony is
auscultated. Have pt. whisper 1,2,3. Sound should be faint and muffled. Clear with lung consolidation.
