THORAX, LUNGS, AND CARDIOVASCULAR SYSTEM ✓ Solved

The examination of the thorax, lungs, and cardiovascular system involves a systematic approach focusing on both inspection and palpation to assess the patient's respiratory and cardiovascular health. This examination is critical for identifying any potential abnormalities that could indicate underlying health issues.

Positioning the Patient

Begin the examination by positioning the patient appropriately. The patient should be in a supine position or reclined at about a 45-degree angle. This orientation facilitates better access to the thorax and lungs.

Exposure of Necessary Areas

Expose the upper body adequately for the examination while ensuring the patient remains warm. Undressing the patient from the waist up is ideal to allow for thorough inspection of the thoracic region.

Initial Inquiry

Before proceeding with the assessment, inquire about any concerns the patient might have regarding their breathing, which establishes a rapport and helps direct the examination appropriately.

Thoracic Assessment

Inspection

Inspect the thorax for signs of respiratory difficulty. The chest should appear symmetric, with the spine vertically aligned. Look for any deformities in shape and assess the movement of the chest during respiration.

Chest Expansion

To assess chest expansion, place your hands on the patient's chest, inferior to the nipples, wrapping your fingers around either side. Ask the patient to take a deep breath and observe the movement of your thumbs; they should move apart symmetrically. Normal findings indicate no collapse or pneumonia.

Tactile Fremitus

Palpating for tactile fremitus can help identify abnormalities. Place your hands on the posterior aspect of the chest and ask the patient to speak. Equal and moderate vibrations should be noted during speech, signifying normal lung function.

Percussion

Percuss the posterior chest to evaluate diaphragmatic excursion. A normal interval is about 5 cm. During percussion, bronchial breath sounds should be audible over the trachea.

Auscultation

Auscultate the posterior breath sounds, ensuring to check for any skin abnormalities or abnormal breath sounds in the lateral aspects of the back. Additionally, perform assessments for egophony, bronchophony, and pectoriloquy, expecting to find no abnormalities.

Anterior Chest Examination

Inspection

The anterior chest should be inspected for its normal size and shape. Look for size discrepancies, shape abnormalities, bruising, or other issues. The skin should be warm, dry, and the chest should feel symmetrical upon expansion.

Auscultation and Percussion

Auscultate for tactile fremitus on the anterior chest, noting any moderate vibrations during speech. Perform percussion on the anterior chest; normal findings typically involve resonance. The anterior breath sounds should also be normal.

Cardiovascular System Assessment

Jugular Venous Pressure (JVP)

Assess the JVP by estimating the vertical distance above the midpoint of the right atrium. A measurement of approximately 7 cm H2O is considered normal.

Pulses Assessment

Evaluate the carotid and brachial pulses. Normal findings typically include a carotid pulse rate of about 70 beats per minute (bpm) and a brachial pulse rate of 90 bpm. These measurements can provide insight into the cardiovascular health of the patient.

Point of Maximum Impulse (PMI)

Locate the PMI, which is generally found near the mid-clavicular point in the fifth intercostal space. Palpate for any thrill or bruit, which should normally be absent, indicating no abnormal vascular sounds.

Auscultation of Heart Sounds

Finally, auscultate the heart sounds to assess the overall cardiovascular function. A normal examination should reveal clear heart sounds with no irregularities.

Conclusion

The thorough examination of the thorax, lungs, and cardiovascular system provides critical insights into the patient's respiratory and cardiovascular health. Proper positioning, exposure, and systematic assessment can identify potential health issues, guiding further diagnostic processes or interventions as necessary.
