In a state of hypercapnia, the accumulation of carbon dioxide in the blood causes the pH of the blood to drop, leading to a state of respiratory acidosis.

Bradypnea is less than 12 breaths per minute, and tachypnea is greater than 20 breaths per minute. Break up the assessment by listening to the anterior lung sounds and then the heart sounds and allowing the patient to rest before listening to the posterior lung sounds.

It is best to examine the precordium with the patient supine because if the patient is turned on the left side, the apical region of the heart is displaced against the lateral chest wall, distorting the chest movements.
