- Malaise, fatigue
- Pleuritic pain
- Decreased breath sounds or crackles
- Crackles or absent sounds due to so much consolidation in lungs
- Tachypnea
- Dullness w/ percussion bc of consolidation of fluid where air should be in lungs
22
Q
Pneumothorax
A
- What: air leaks from lungs to → pleural space in between lung and chest wall → collapses lungs
- Closed: spontaneous, traumatic, iatrogenic (caused by exam/Tx)
- Causes include high altitudes, deep scuba diving, etc.
- Risk factors for spontaneous pneumothorax: adolescent, thin, tall boys
- Open: due to penetration
- Causes surgical accidents

- Cyanosis
- Anxiety
- Resp distress
- Tracheal displacement
- Tx: get into pleural space to let air out so lung can refill
23
Q
Asthma (what, S&S, Tx)
A
- What: hyperreactive airway disease causing bronchoconstriction, obstruction, and inflammation
- Reversible → can be treated w/ meds during Sx attack
- S&S:
- Tachypnea
- Tachycardia
- Secondary muscle use (🚩)
- Expiratory wheezing
- Chest “tightness”
- Tx: goal have pt in mild persistent to moderate persistent range w/ appropriate Tx
- Acute: bronchodilators (ie. inhalers)
- Quick-acting inhalers: only for immediate Sx relief
- Chronic: anti-inflammatory (ie. long-acting steroids)
- Long-acting Tx: helps limits amt of attacks so they wouldn’t need short acting as much ⇒ not for Sx relief
- Acute: bronchodilators (ie. inhalers)
24
Q
Asthma Type I: Mild Intermittent
A
- Sx occur less than couple times/wk during waking hrs
- < 2/month at night (waking up coughing/wheezing)

- Have pt keep inhalers
25
Asthma Type II: Mild Persistent
- Sx occurs more than 2/wks but not daily
- < 2/month at night (waking up coughing/wheezing)
- Can still have asthma attacks that interfere w/ activity temporarily
- Peak flow variability 20 - 30%
26
Asthma Type III: Moderate Persistent
- Asthma attacks at least couple times/wk ⇒ interferes w/ daily activities and lasts for days at a time
- Waking up at night w/ Sxs
- Sx pops up most days
- Have to use inhaler almost every day
- Greater peak flow variability 30% +
27
Asthma Type IV: Severe Persistent
- Pt can’t be at home anymore
- Continuous Sxs
- Severe activity limitations
- Frequent attacks at night
28
COPD: Chronic Bronchitis
- What: inflamed and narrowing of airway/bronchi lining ⇒ hypersecretion of mucus by goblet cells ⇒ difficulty breathing
- S&S:
- Productive chronic cough (minimum 3 months x 2 yrs)
- Sputum mucoid to purulent may be bloody
- Ronchi
- Crackles
- Recurrent wheezing
- Cyanosis (most w/ emphysema due to increased CO2)
- Dyspnea
- Risk factors: Age & Prolonged Hx of tobacco abuse
29
COPD: Emphysema
- What: chronic lung disease damaging and enlarging alveoli ⇒ difficulty breathing
- S&S:
- Enlarged alveoli that tries to hold onto air
- Barrel chest due to flattening of costal angle
- SOB
- Tripod position (secondary muscle use 🚩)
- Decreased breath sounds (crackles, wheezing, cough) depending on where they are in disease progression state
- Clubbing
- Polycythemia (↑ hgb) as body attempts to get more oxygen

- Hypercarbia (↑ CO2 < bronchitis)
- Cyanosis (during severe conditions)
- Malnutrition (during severe conditions)
- Risk factors: Age & Smoking
30
Lung Cancer

31
How to Document Dyspnea Subjective Grades 0-4
- Grade 0: not troubled by breathlessness except w/ strenuous exercise
- Grade 1: troubled by SOB when hurrying on lvl path or walking up slight hill
- Grade 2: walks more slowly on lvl path than ppl of same age bc of breathlessness or has to stop to breathe when walking on lvl path at own pace
- Grade 3: stops to breathe after walking ~100 yrds on lvl path
- Grade 4: too breathless to leave house or breathless when dressing/undressing
32
How to Document Dyspnea Objective
- Tachypnea: shallow breathing w/ increased RR
- Bradypnea: slower rate of breathing (may be periodic, regular intervals)
- Apnea: absence of breathing (may be episodic, irregular intervals)
- Hyperpnea: increased depth of breathing
- Kussmaul: rapid, deep breathing w/o pauses
- In adults: > 20 RR, labored breathing w/ deep breaths that resembles sighs
- Cheyne-Stokes: breaths that gradually become faster and deeper than norm, then slower, and alternate w/ periods of apnea
- Cause: diabetes, severe life crisis
- Doesn’t resolve until you treat underlying condition
- Common in: end of life oncology pts, severe heart failure
- Biot: rapid, deep breathing w/ abrupt pauses between each breath; equal depth to each breath
- Cause: damaged brain pons often due to stroke or trauma that increases region’s pressure
33
Red Flags
- Loss of synchrony between left and right lung ⇒ suggests pt has blood or fluid in space ⇒ lungs not inflating
- Presence of stridor ⇒ caused by obstruction in upper airway
- Secondary muscle use ⇒ means pt needs to use other muscles to breathe and get oxygen even at rest
- Expiratory grunt ⇒ sign of resp distress
- Grunting comes w/ closure of glandis that switches back and forth between esophagus and trachea to increase end expiratory lung pressure to prolong alveolar gas exchange ⇒ enhances ventilation and perfusion
- Cyanosis ⇒ might indicate intrathoracic disease w/ lower resp involvement
- During severe asthma exacerbation ⇒ wheezing may decrease or stop due to lack of airflow in bronchial tree ⇒ emergency
34
age-related considerations INFANTS
- Hemoptysis rare
- Barrel chest normal until they’re 2 yo
- Have thinner chest wall w/ more prominent bony structures compared to adults
- Have larger head circumference compared than chest circumference until they’re 2 yo
35
age-related considerations CHILDREN
- Hemoptysis rare
- Cyanosis more common in children
36
age-related considerations OLDER ADULTS
- Barrel chest can occur again as normal part of aging due to normal gradual loss of muscle, strength, thorax, diaphragm, and lung resiliency
- Still make sure to rule out COPD though
- Alveoli becomes less elastic ⇒ ↑ fatigue, dyspnea, exertion
- Mucous membranes become drier
37
age-related considerations PREGNANT WOMEN
Experiences changes in resp function but not RR
38
health education and promotion
- tobacco cessation
- vax: influenza, pneumococcal, pertussis, covid
39
Inspection of Chest Shape’s
- Norm ratio: 0.7 – 0.75
- Increases w/ age
- AP diameter may increase in COPD
40
Inspection of Ribs Costal Angle
- Norm: < 90*
- If angle is > 90* ⇒ caused by overinflation of lungs mostly associated w/ COPD but also seen in cystic fibrosis
41
Percussion for Underlying Tissue
- Percuss for sound to find out if underlying tissue has air or fluid, in excess, etc.
- Sounds: flat, dull, resonant, hyperresonant, tympanic
- Step: tap on intercostal spaces between each rib
- Norm: sound is resonant
42
Palpation of Chest Expansion
- Steps: both hands on back → slide them medially just enough to raise loose fold of skin on each side between thumb and spine → ask pt to inhale deeply → let hands expand w/ chest movement → watch distance between thumbs as they move apart during inspiration → feel for range and symmetry of rib cage as it expands and contracts
- Norm: bilateral, equal movement of thumbs/hand apart
- Unequal movement ⇒ lung deflated
- Causes of unilateral decrease or delay in chest expansion include: pleural effusion, lobar pneumonia, pleural pain w/ associated splinting, unilateral bronchial obstruction, chronic fibrosis of underlying lung/pleura
43
Palpation of Tactile Fremitus
- Fremitus: palpable vibration transmitted thru bronchopulmonary tree to chest wall as pt is speaking
- Steps: use ball (bony part of palm at base of fingers) or ulnar surface of your hand to optimize vibratory sensitivity of bones in hand → ask pt to repeat words “99” or “1 on 1” → if fremitus faint, ask pt to speak more loudly or in deeper voice
- Fremitus decreased or absent when pt voice is too soft or when transmission of vibration from larynx to surface of chest impeded
- Causes include: thick chest wall, obstructed bronchus, COPD, pleural effusion (fluid in pleural space impacting lung tissue), fibrosis (pleural thickening), pneumothorax (collapsed lung), infiltrating tumor
- Fremitus increased over areas where there’s consolidation (pneumonia) unilaterally from increased transmission
- Norm: symmetrical vibrations felt when pt is speaking
