2. Lobes and Landmarks

3. Performing the Assessment: Subjective Data ROS -Ask about dyspnea, cough, chest pain (PQRST format) ROS -Ask about dyspnea, cough, chest pain (PQRST format) Short interview sessions if resp. distress / tiring easily Short interview sessions if resp. distress / tiring easily Past health history Past health history –AllergiesMeds –ImmunizationsTravel history –Childhood illnessFamily history –HospitalizationsTB, smoking Psychosocial Assessment Psychosocial Assessment

4. Assessment Cont.: Objective Data Inspection… …Always first!!!

5. Assessment begins…. The moment you see the patient. The moment you see the patient. What position is most comfortable for him? Does he appear relaxed, anxious, uncomfortable? Is he having any trouble breathing? Tripod Position

6. Focused Assessment (con’t) Inspection Inspection Color, Size and shape & symmetry of chest, any lesions or scars Color, Size and shape & symmetry of chest, any lesions or scars –Anterior LateralPosterior

7. Altered size/shape: Barrel Chest Increased AP:Transverse Diameter Increased AP:Transverse Diameter Costal angle >90 degrees Costal angle >90 degrees 1:22:1

8. Barrel Chest

9. Asymmetrical chest Scoliosis

10. Normal Breathing

11. Intercostal Spaces and Muscles Retractions

12. Focused Assessment Cont… Resp. rate and depth Resp. rate and depth Pattern of respiration – regular rhythm Pattern of respiration – regular rhythm Abnormal patterns Abnormal patterns –Hyperventilation –Tachypnea vs. bradypnea –Stertorous (Noisy)

13. Looking at related structures Skin: cyanosis, pallor Skin: cyanosis, pallor Nails: Clubbing Nails: Clubbing –Spongy nail matrix and nail angle of greater than 160 degrees

14. Focused Assessment Cont.: Palpation Check for tenderness Check for tenderness (normally nontender) Crepitus – SQ air pockets Crepitus – SQ air pockets Tactile fremitus – increased with fluid accumulation Tactile fremitus – increased with fluid accumulation Abnormal if tumor, fractured ribs, chest tubes, wound site, fluid

15. Focused Assessment: Auscultation

17. Normal Breath Sounds

18. Adventitious/Abnormal Breath Sounds (T 11-2) p.132 Continuous sounds Wheezes Wheezes –Sibilant –Sonorous (Rhonchi) Discontinuous sounds Crackles (Rales) Crackles (Rales) –Fine –Course –*Atelectic crackles –Pleural friction rub

19. Wheezes (Continuous) Sibililant wheeze high-pitched musical sounds heard first when a patient exhales high-pitched musical sounds heard first when a patient exhales Partial blockage in airflow Partial blockage in airflow Sonorous wheeze (rhonchi) low pitched – snoring, rattling sound low pitched – snoring, rattling sound heard primarily when the pt exhales Air passes through large airways filled with fluid/ secretions Air passes through large airways filled with fluid/ secretions

20. Crackles (Discontinuous) FINE /COURSEFINE /COURSE Caused by collapsed or fluid- filled alveoli popping openCaused by collapsed or fluid- filled alveoli popping open usually heard in the lung bases during inhalation usually heard in the lung bases during inhalation Atelectic crackles Pleural friction rub – pericarditis

21. Abnormal Breath Sounds Diminished breath sounds Diminished breath sounds Absent breath sounds Absent breath sounds

22. Interpreting what you hear… Note whether the sound occur during inhalation or exhalation, or both. Note whether the sound occur during inhalation or exhalation, or both.
