1. Respiratory system examination

2. 01 Introduction to respiratory system examination

3. Inspection of Respiratory System Observation of breathing patterns Assess the rate, depth, and rhythm of breathing, and note any signs of distress or labored breathing. 01 Assessment of chest symmetry Examine for any asymmetry, deformities, or abnormal movements during breathing. 02 Evaluation of skin color and condition Check for cyanosis, pallor, or any signs of peripheral cyanosis on the lips and nail beds. 03

4. Palpation of Respiratory System Assessing tactile fremitus Palpate for vibrations while the patient speaks to assess for any abnormalities or asymmetry. Identifying chest tenderness Gently palpate the chest wall to check for tenderness, which may indicate underlying pathology. Detecting crepitus or subcutaneous emphysema Palpate for abnormal crackling sensations under the skin, which may be indicative of air accumulation.

5. Auscultation of Respiratory System Listening for breath sounds Use a stethoscope to listen for normal vesicular, bronchial, or abnormal breath sounds in different lung fields. Identifying adventitious sounds Recognize crackles, wheezes, or stridor that may indicate underlying respiratory conditions. Assessing vocal resonance Listen for changes in vocal resonance to detect potential abnormalities in lung tissue density.

6. 02 Key steps and techniques in conducting a respiratory system examination

7. Preparation for examination Patient positioning and comfort Ensure the patient is seated comfortably and upright, facilitating optimal lung expansion and assessment of respiratory effort. 01 Equipment check Verify the functionality of the stethoscope, pulse oximeter, and other necessary tools for accurate examination and monitoring. 02 Patient briefing Explain the examination process to the patient, including the need for deep breathing and potential discomfort during certain maneuvers. 03

8. Physical examination of the respiratory system Inspection of the chest and respiratory rate Observe the chest for symmetry, deformities, and use of accessory muscles. Count the respiratory rate to assess breathing pattern. Percussion and palpation Perform percussion to assess the density of lung tissue and palpation to identify tenderness, crepitus, or masses in the chest wall. Auscultation of breath sounds Listen to breath sounds using the stethoscope, differentiating between normal vesicular, bronchial, and adventitious sounds.

9. Additional assessments and investigations Spirometry and peak flow measurement Conduct spirometry to assess lung function and measure peak expiratory flow rate, aiding in the diagnosis of respiratory conditions. Chest X-ray and imaging studies Order chest X-ray or other imaging studies to visualize lung structures and identify abnormalities such as infiltrates, effusions, or masses. Arterial blood gas analysis Obtain arterial blood samples to evaluate oxygen and carbon dioxide levels, as well as pH, providing insights into respiratory and metabolic status.
