Overview

The medical manifestations of respiratory acidosis are regularly the ones of the underlying disorder. Physical examination may vary, relying on the severity of the disorder and on the rate of development of hypercapnia. mild to moderate hypercapnia that develops slowly generally has minimum symptoms.

Physcial Examination

  • Physical examination of patients with respiratory acidosis is usually non specific.[1][2][3][4][5]

Lungs

  • In COPD patients physcial exmanination of chest shows
    • Diffuse wheezing
    • Barrel chest
    • Decreased breath sounds
    • Hyperresonanc
    • Prolonged expiration
    • Rhonchi

Appearance of the Patient

  • Patients with respiratory acidosis usually appear Anxious

Skin

  • Cyanosis
  • Digital clubbing 

Neuromuscular

  • Seizures.
  • Asterixis.
  • Myoclonus.

HEENT

  • Papilledema.
  • Conjunctival and superficial facial dilation of blood vessels.
  • Nasal flaring is a sign of respiratory acidosis.[6][7]
