The distance between the transition point on full expiration and the transition point on full inspiration is the extent of diaphragmatic excursion (normally 3–5.5 cm).Abnormally high transition points on one side may be seen in unilateral pleural effusion and unilateral diaphragmatic paralysis.The transition point from resonant to dull percussion notes marks the approximate position of the diaphragm.

Move downwards while percussing over both sides of the chest wall.Sign of fluid inside the thoracic cavity : pneumonia, pleural effusion.Sign of increased air inside the thoracic cavity: emphysema, bronchial asthma, pneumothorax.Physiological finding: resonant percussion note (a comparatively hollow and loud note).Often the finding of asymmetry is more important than the specific percussion note that is heard. Always percuss both sides of the chest at the same level.Strike the joint with the other middle finger and evaluate the elicited sound.Hyperextend the nondominant middle finger and place the distal interphalangeal joint against the chest wall.Nasal flaring or flaring of the nostrils.Jugular, sternal, and intercostal retraction.Hemoptysis: See " Etiology of hemoptysis.”.Blackish-brown: possibly old blood should be further investigated (can also be a harmless incidental finding).Grayish: pneumoconiosis, a waning bacterial infection.Green: an indication of a pseudomonal infection.White and translucent: viral infection (for example, bronchitis that presents with a typical early-morning cough).Kyphosis or scoliosis may lead to decreased forced vital capacity, forced expiratory volume and overall respiratory function.Asymmetric movement may be associated with pleural disease, phrenic nerve damage, or pleural effusion.The anteroposterior diameter of the thorax may increase in COPD, leading to a “ barrel chest” appearance.When there is nail clubbing, the normal diamond-shaped “window” between the nail beds will not be seen.Place distal phalanges against each other so that both fingernails touch.Nail bed feels spongy when pressed and springs back when released.
