Respiratory assessment
Respiratory Assessment

  • Thoracic cage bony conical shape with narrow at top

  • Defined by sternum, 12 pairs ribs and 12 thoracic vertebrae

  • Rib 1-7 attached to sternum via costal cartilages

  • Rib 8,9,10 attached to costal cartilage

  • Rib 11,12 “floating” with free palpable tips

  • Anterior thoracic Landmarks;

    • Suprasternal notch, “U” shaped


Respiratory assessment

Sternum-”breastbone” has three parts:

The body

The xiphoid

The Manubrium

Manubriosternal Angle- “Angle of Louis”-is articulation of the manubrium and the body of the sternum; continuous with the 2ed rib; marks site of the tracheal bifurcation into the R & L bronchi

Costal Angle- R & L costal margins form angle where meet at xiphoid process


Respiratory assessment

  • Posterior thoracic Landmarks

    • Vertebra Prominens

    • Spinous Processes

    • Interior Boarder of Scapula

    • 12th Rib

  • Anterior Chest

    • Midsternal Line

    • Midclavicular Line- bisects the center of each clavicle at point halfway between the palpated sternoclavicular and acromioclavicular joint, near nipple line


Respiratory assessment

  • Posterior Chest

    • vertebral Line- midspinal

    • Scapular line- extends through inferior angle of scapula

  • Lateral Chest- Lift arms 90* & divide by 3 lines

    • Anterior axillary- down from anterior axillary fold to where the pectoralis major muscle inserts

    • Posterior anillary down from posterior axillary fold to where latissimus dorsi muscle inserts


Respiratory assessment
;

  • Midaxillary line-down from apex of axilla, lies between and parallel to other two

  • Thoracic cavity

    • Mediastinum- middle section of thoracic cavity contains esophagus, trachea, heart and great vessels; and the Left & Right pleural cavities

    • Lung Borders- anterior

      • Apex 9 highest point of lungs 3-4 cm above inner 3rd of clavicles

      • Base- lower border, rest on diaphragm about 6th rib in midclavicular line


  • Respiratory assessment

  • Lungs- 2 pair

  • Anterior

    • Right lung shorter because of underlying liver; has 3 lobes

      • Anterior Right Upper Lobe (RUL)

      • Right Middle Lobe (RML)

      • Right Lower Lobe (RLL)

        - Left Lung- narrower because heart bulges

        to left; has 2 lobes


  • Respiratory assessment

  • Posterior

    • Right Upper Lobe (RUL) and Left Upper Lobe (LUL)- from apices at T1 down to T3

    • Right Lower Lobe (RLL) and Left Lower Lobe (LLL)- from the above border to T10 on expiration and to T12 on inspiration.

  • Pleurae- thin slippery which forms an envelope between lungs and chest wall.

  • Visceral Pleura- lines outside of lungs down into fissures


  • Respiratory assessment

    • Parietal Pleura- lining inside the chest wall and diaphragm.

    • Trachea- lies anterior to esophagus; is 10– 11 cm long in adult; starts at cricoid cartilage bifurcates below sternal angle into R and L bronchi; posterior bifurcates at T4 or T5;

      R bronchus shorter wider;

      L bronchus vertical than L main


    Respiratory assessment

    • Function of Trachea and bronchi- transport gases between environment and lung parenchyma.

      • Bronchial tree- protect alveoli from small particulate matter in the inhaled air

      • Bronchi lined- goblet cells which secrete mucus that entraps particles

      • Bronchi line with cilia- which sweeps particles upward swallowed or expelled

      • Acinus- functional respiratory unit consist of bronchioles, alveolar ducts, alveolar sac and alveoli


    Respiratory assessment

  • Major function of Respiratory System-

    • Supply oxygen to body for energy production

    • Remove CO 2 as waste product for energy reaction

    • Maintaining homeostasis (acid-base balance) of arterial blood

    • Maintaining heat exchange (less important to humans)


  • Respiratory assessment

    • Control of Respirations

      • Involuntary control mediated in respiratory center in brain stem (pons & medulla)

      • Change in carbon dioxide and oxygen levels in blood

      • Hypercapnia- Increase of carbon dioxide-stimulus to breathe

      • Hypoxemia ) decrease in oxygen in blood can cause increase in respirations but less effective

      • Hypoventilation – slow, shallow breathing causes carbon dioxide to build in blood


    Respiratory assessment

    -With age less surface area available for gas exchange

    Increases older person risk for postoperative pulmonary complications due to decreased ability to cough


    Respiratory assessment

    • Assessment ( need to note normal from abnormal)

      A. Subjective Data: questions to ask-what client tells you

      • Cough - cold in particular to children; how frequent, when, time of day, contributing factors; what kind of cough (hacking, dry, with blood), what makes it worse or better

      • SOB- older adults on exercise

      • Chest pain with breathing

      • History of respiratory infections- chronic


    Respiratory assessment

    allergies, history of asthma, TB.

    Pulmonary disease in older adults

    5. Environmental exposure- where did you or do you work, do you smoke, do you live or work near pollutants

    6. Self care behavior- chest x-ray, TB testing, etc.

    • Allergies in family- particularly in children


    Respiratory assessment

    Objective

    • Inspection (what you see)

      • Shape and Configuration of chest wall.

        • Thorax symmetric, elliptical shape with downward sloping ribs

        • Any signs tumors, lumps, bruising on chest

        • Check shape for:

          • Scoliosis (“s” shape)

          • Kyphosis (humpback)

          • Barrel chest


    Respiratory assessment

    Skin color and condition

    • Person’s position

    • Level of consciousness (LOC)

      B. Palpation

  • Symmetric expansion- place hands of posterolateral chest wall with thumbs at level of T9 or T10; Slide hands medially to pinch up a small fold of skin between thumb; have person take a deep breath


  • Respiratory assessment

    your thumbs should move apart symmetrically

    • Tactile Fremitus- palpable vibrations- with palmar base ( the ball) of fingers or ulna edge of one hand touch person’s chest and have then repeat “ninety-nine” or “blue moon” should feel vibration; varies among people but symmetry most important

      Affecting normal intensity of Tactile Fremitus:

      -Relative location of bronchi to chest wall

      - Thickness of chest wall


    Respiratory assessment

    - Pitch and intensity

    Check for:

    Decreased fremitus

    Increased fremitus

    Rhonchal fremitus

    Pleural friction fremitus

    Crepitus

    CPercuss

    • Tapping on client’s skin with short sharp strokes to assess underlying structure


    Respiratory assessment

    • Strokes yield palpable vibrations and characteristics sounds that depict location, size, density of underlying organ pg.163

    • Two methods-

      • Direct- striking hand direct contact with body wall. Used in infant’s thorax and adult sinus areas

      • Indirect- use both hands. Striking hand

        contacts stationary hand fixed on client’s skin


    Respiratory assessment

    Avoid striking client’s ribs & scapulae, always a dull sound & yields no data

    Lung Field

    • Start at apices at top of both shoulders

    • Percuss interspaces comparing side to side going down lung region

      • Hyperresonance- too much air present

      • Resonance-voice heard through stethoscope; is muffled nondistinct


    Respiratory assessment

    -Dull- abnormal density in lung sound & yields no data

    c. Diaphragmatic Excursion- mapping out lower lung border at expiration & inspiration; somewhat higher due to liver

    C. Auscultation-with the diaphragm of stethoscope from apex to base, from side to side.


    Respiratory assessment

    a. Evaluate the presence and quality of normal breath sounds.

    b. With flat diaphragm of stethoscope listen at least one full respiration in each location

    c. Compare side to side and top to bottom ( Go from left to right and then down or from right to left and then down

    d. analyze breath sounds

    e. detect any abnormal sounds

    f. examine sounds produced by spoken word

    g. pulse oximeter-noninvasive method of assessing arterial oxygen saturation (SpO2)


    Respiratory assessment

    h Listening to own breathing sounds.

    Stethoscope tubing bumping

    Patient shivering

    Patient has hairy chest

    Rustling of paper gown

    Music or talking in background

    i. Normal breathing Sounds- for adults

    • Bronchial (tracheal) –loud, high pitched, over trachea and larynx

    • Bronchovesicular-moderate, moderate pitch, over major bronchi posterior between scapular especially right anterior upper sternum at 1st and 2ed intercostal spaces


    Respiratory assessment

    c. sounds.Vesicular- Soft, low pitch, rustling sound of wind through trees; over peripheral lung field

    • Decreased Sounds

    • Obstruction- by secretion, mucus

      plug or foreign body

    • Loss of Elasticity- in lung fiber &

      decreased force of inspired air

    • Something obstructs transmission

      of sound between lung and

      stethoscope

      2. No breath sounds- no air moving; ominous sign


    Respiratory assessment

    3. Increased breath sounds-bronchial sounds.

    sounds are abnormal when heard

    over abnormal location

    • Adventitious Sounds- sounds not normally heard in the lungs; if present are superimposed on breath sounds

      1. Crackles- rales

      2. Wheeze – rhonchi

      3. Atelectaticcrackles-short, popping, crackling sounds like fine crackles


    Respiratory assessment

    • Voice Sounds- sounds. Vocal Resonance ; soft muffled indistinct, heard through stethoscope

      1. Bronchophony-repeat “99”- soft,muffled, indistinct heard through stethescope cannot distinguish. 2.Egophony- auscultate chest person phonates long “ee-ee-ee-ee-” through stethoscope

      3. Whispered pectoriloquy- perslecton whispers phrase “one-two-three”; response faint, muffled and almost inaudible


    Respiratory assessment

    • Normal Adult Respiration Patterns sounds.

      • Rate- 10 to 20 breaths/minute

      • Depth- 500 ml to 800 mo

      • Pattern- even

      • Ratio to Respiration- fairly constant 4:1

      • Depth- air moving in & out each respiration

      • Sigh- occasional normal pattern; purposeful to expand alveoli

    • Respiration Patterns:

      • Tachypnea- rapid shallow breathing; increased to >24


    Respiratory assessment

    • Bradypnea sounds.- Slow breathing decrease but regular; < 10/minute

    • Cheyne-Stokes- breathing periods last 30 to 45 seconds, with periods of apnea (20 seconds); alternating the cycle

    • Hyperventilation- Increase both in rate and depth

    • Hypoventilation- irregular shallow pattern

    • Biot’s Respiration- similar to Cheyne-Stokes except pattern is irregular

    • Orthopnea- difficulty breathing when supine

    • Paroxysmal nocturnaldyspnea-is awakening from sleep with SOB & needs to be upright to achieve comfort


    Respiratory assessment

    • Hyperventilation sounds.- rapid, deep breathing causes carbon dioxide to be blown off

  • Chest size changes-

    • Inspiration- lung size increases; diaphragm descends and flattens; negative pressure air rushes in

    • Expiration- chest size recoils; diaphragm decreases in chest size and relaxes; positive pressure air flows out


  • Respiratory assessment

    • Abnormal Tactile Fremitus sounds.

      • Increased tactile Fremitus-increased density of lung tissue, thereby making a better conducting medium for vibration

      • Decreased Tactile Fremitus- anything obstructs transmission of vibration.

      • Rhonchal Fremitus- vibration felt when inhaled air passes through thick secretions in larger bronchi

      • Pleural Friction Fremitus- inflammation of the parietal or visceral pleura causes a decrease

        in normal lubricating fluid


    Respiratory assessment

    • Adventitious Lung Sounds sounds.:

    • Discontinuous Sounds- are discrete crackling sounds

      • Crackles-fine; formerly called rales, high-pitched, short crackling, popping sounds heard during inspiration cannot be cleared by coughing

      • Crackles-coarse; loud, low-pitched, bubbling & gurgling sounds that start in early inspiration and may be present in expiration; sound like Velcro fastener opening

      • Atelectatic crackles; sound like fine crackles, but do not last and are not pathologic


    Respiratory assessment

  • Continuous Sounds are musical sounds

    • Wheeze- high pitched- musical sound that sound polyphonic; predominately in expiration but may occur in inspiration & expiration

    • Wheeze- low pitched- rhonchi; monophonic single note; musical snoring; moaning sound; more prominent on expiration; may be cleared by coughing

    • Stridor- high pitched- monophonic, crowing sound, heard on inspiration


  • Respiratory assessment

    • Common Respiratory Conditions: inspiratory and expiratory

      • Atelectasis-collapsed shrunken section of alveoli or entire lung due to:

        • Airway obstruction, Compression on lung, Lack of surfactant

    • Effusion maybe; Transudative (watery capillary fluid), Exudatative ( protein),

      Empyemic (purulent matter)


  • Respiratory assessment

    Hemothorax (blood),Chylothorax (Milky lymphatic fluid) bronchioles

    • Presence of fluid subdues lung sounds

    • No adventitious sounds

    • Pt. exhibits-increased respirations, dyspnea

      dry cough, abdominal distention, cyanosis

  • Heart Failure- pump failure increasing pressure of cardiac overload causes pulmonary congestion

    • Bronchial mucosa may beswollen

    • Dependent airways deflated

    • Engorged capillaries


  • Respiratory assessment

  • Respiratory assessment

    • Pulse Oximeter- noninvasive method to assess arterial oxygen saturation (Spo2) Sensor attaches to client’s finger detector measures amount of light absorbed by oxyhemoglobin (HbO2) and unoxygenated (reduced) hemoglobin (Hb); ratio of light emitted to light absorbed con converts to % of oxygen saturation; Healthy person no lung disease or anemia has a Spo2 of 97% to 98 %.

    • 12 minute distance (12MD) walk, clinical measure of functional status of clients with COPD; used as outcome measure for



    Respiratory assessment

    • Infants and children saturation (Spo

      • Inspect and then listen to lung sounds of infants sleeping, can concentrate on breath sounds

      • May sit in parents lap and play with stethoscope reduces fear

      • Older children like to listen to their own lungs

        A. Inspection

      • Infants has rounded thorax with equal anteroposterior-to-transverse chest diameter


    Respiratory assessment

    • Infants and Children saturation (Spo

      • Respiratory system develops in utero

      • Respiratory system doesn’t function till birth

        • At birth when cord cut blood gushes to pulmonary circulation, the foramen oval in heart closes, the ductus arteriosus contracts and closes some hrs. later and the pulmonary circulation functions

        • In childhood-respiratory development continues, increases in diameter and length in size and number of alveoli


    Respiratory assessment

    • Chest wall thin with little musculature; ribs & xiphoid are prominent; thoracic cage soft & flexible

    • Newborn first respiratory assessment is part of Apgar scoring system to measure successful transition to extrauterine lifescored at 1 minute and at 5 minutes after birth; 1 minute score of 7 to 10 very good condition, needs only suction of nose and mouth

    • Age 6 thorax ratio is 1:2 (anteroposterior-to-transverse diameter) pg 464; Count respiratory rate for 1 full minute; normal rate is 30 to 40 breaths/minute; may go to 60/minute; get count when infant asleep


    Respiratory assessment

    • Breathe through nose rather than mouth prominent; thoracic cage soft & flexible

    • Intercostal muscles not well developed

    • Abdominal bulges with each inspiration but see little thoracic expansion

      B. Other observations

      Evidence of Infection, Cough, Wheezes,

      Cyanosis, Chest Pain, Sputum, Bad

      breath


    Respiratory assessment
    , prominent; thoracic cage soft & flexible

    C. Palpation

    encircle infant’s thorax with both hands; should be no lumps, masses or crepitus; may feel costochondral junctions.

    D. Percussion-limited, fingers of adult too large

    in relation to tiny chest.; note hypper-

    resonance occurs normally in infants

    and young child due to thin chest wall

    E. Auscultation-normally bronchovesicular

    breath sounds in infants up to 5-6 year

    old; breath sounds are louder and

    harsher

    -fine crackles commonly heard immediate


    Respiratory assessment

    in newborns prominent; thoracic cage soft & flexible

    -Cackles in upper lung field occur with cystic fibrosis

    -Expiratory wheezing occurs in lower airway obstruction e.g., asthma, bronchiolitis

    -Stridor- high pitched inspiratory crowing with upper arway obstruction, e.g., croup, foreign body aspiration, acute epiglottitis


    Respiratory assessment

    • Depth of respirations- prominent; thoracic cage soft & flexible

      • Hyperpnea- too deep

      • Hypopnea- too shallow

    • -Retraction- sinking in of soft tissue relative to the cartilaginous and bony thorax; in severe airway obstruction- retraction extreme.

    • Nasal flaring- sign of respiratory distress

    • Head bobbing- in sleeping or exhausted infant sign of dyspnea


    Respiratory assessment

    • Noisy breathing- “snoring” obstruction, polyps or foreign body in nasal passages

    • Grunting- sign of chest pain- acute pneumonia/ pleural involvement

    • Chest pain-older children maybe pulmonary and or nonpulmonary

    • Clubbing- proliferation of tissue about the terminal phalanges, associated with chronic hypoxia, chronic pulmonary disease or primarily cardiac defect

    • Cough- maybe associated with respiratory disease; is protective mechanism


    Respiratory assessment

    F. Tests foreign body in nasal passages-

    • Pulse oximetry- similar to adults however can position around foot, toe, earlobe

    • Transcutaneous Oxygen Monitor –Tc Po2

      measures O2 diffusion across skin

      G. Oxygen Therapy

    • Delivered by mask, nasal cannula, tent, hood, face tent, or ventilator

    • Oxygen mask- various sizes, delivers higher O2 concentration than cannula; can cause skin irritation

    • Nasal Cannula-low-moderate O2


    Respiratory assessment

    • concentration; can talk ad eat; must have foreign body in nasal passagespatent nasal passages

      • Oxygen Tent-lower O2 concentrations; can increase concentration while eating; fit around bed to prevent leakage; cool & wet environment; poor access to child

      • Oxygen hood, face tent- high O2 concen-tration; free access to child’s chest; high humidity; need to be removed for feeding & care; humidified O2 not blown directly on infants/child face

      • Masks not well tolerated by child


    Respiratory assessment

    • Pregnancy foreign body in nasal passages

      • Thoracic cage wider; costal angle feels wider; respirations deeper; although this can be quantified only with pulmonary function test

      • Pregnancy induces small degree of hyperventilation as tidal volume increases steadily throughout pregnancy

      • Diaphragm elevated and subcostal angle increased due to enlarging uterus

      • Lung disease maybe aggravated by pregnancy


    Respiratory assessment

    • Pregnancy foreign body in nasal passages

      • As uterus increases elevates diaphragm which decreases the vertical diameter of thoracic cage but is compensated by increase in horizontal diameter.

      • As fetus grows there is increase in oxygen demand on mother’s body; increasing tidal volume( deep breathing)


    Respiratory assessment

    • Aging Adults foreign body in nasal passages

      • Costal cartilages calcifies, less mobile thorax

      • Respiratory muscles strength declines after 50 and continues to do so till 70

      • Decrease in elastic properties of lungs, becomes harder to inflate

      • Decrease in Vital Capacity- maximum amount of air that a person can expel from lungs after first filling lungs to maximum


    Respiratory assessment

    • Increase in Residual Volume- amount of air remaining in lungs even after most forceful expiration

    • With age less surface area available for gas exchange

      -Chest cage increases anteroposterior diameter; looks barrel shape and outward

      curvature of thoracic spine; compensates holding head extended and tilted back

      -Chest expansion decreases though still symmetric

      -cartilages becomes calcified
