Pneumonic for chest x-ray
ABCDEFGHI Adequate: position, inspiration, exposure, rotation (PIER) Bones and soft tissues Cardiac size, valves Diaphragms round, flat, free air Effusions Fields and fissures Great vessels Hilar masses (caution thymus in children) Impression
Identification of special landmarks/anatomy
-Sternal angle (angle of louis)
Where 2nd rib meets with the manubrium and the body of the sternum
Clinically relevant landmarks
-Needle decompression?
2nd intercostal space just superior to the 3rd rib margin (neurovascular bundle runs inferior to each rib) at the mid-clavicular line for emergent decompression tension pneumothorax, followed by chest tube placement
Chest tube insertion?
4th intercostal space at mid or anterior axillary line in the 4th intercostal space just superior to the margin of the 5th rib
Where is T4 located?
Lower margin of endotracheal tube on a chest x-ray
Landmark for thoracentesis?
7th intercostal space
Evaluation of respiration
-Patient’s posture and position?
Patient with obstructive lung disorders will tend to sit leaning forward with shoulders elevated
Evaluation of respiration
-Inspection of the neck?
- Contraction of accessory muscles (sternocleidomastoid, scalenes, or supraclavicular contraction)
- Tracheal position
Lateral displacement of the trachea can occur in?
tension pneumothorax
Thoracic expansion
- Place thumbs at about the level of the 10th ribs with fingers loosely grasping and parallel to the lateral rib cage
- Ask patient to inhale deeply
- Watch the distance between thumbs as they move apart during inspiration and feel for the range and symmetry of the rib cage as it expands and contracts
Tactile fremitus
-Where is it normally more prominent?
- Often more prominent in the interscapular area than in lower lung fields
- More prominent on the right than the left
Percussion
-Pattern for percussion?
Start superiorly percussing both sides of the chest working toward the base proceeding in a “ladder-like” pattern

Stridor
- Wheeze that is entirely or predominantly inspiratory in nature
- Often louder in neck vs chest wall
- Indicates partial obstruction of larynx or trachea (immediate attention needed)
Pleural friction rub
- Inflamed and roughened pleural surfaces grate against each other as they are momentarily and repeatedly delayed by increased friction
- Sounds like creaking, usually during expiration but can occur in both phases of respiration
- Usually confined to a relatively small area of the chest wall
