Breathing patterns can provide valuable insight into a patient’s respiratory function and neurological status. Changes in the rhythm, depth, or rate of breathing often signal underlying medical conditions that require further evaluation.
Normal breathing is steady and rhythmic, typically occurring at a rate of about 12–20 breaths per minute in healthy adults. Bradypnea refers to an abnormally slow breathing rate, often seen with sedative drugs, brain injury, or severe metabolic conditions. Tachypnea describes rapid breathing, usually shallow, that may occur with fever, anxiety, lung disease, or hypoxemia.
Cheyne–Stokes respirations follow a cyclic pattern in which breathing gradually increases in depth, then decreases, followed by a brief period of apnea before the cycle repeats. This pattern is commonly associated with heart failure or neurological disorders. Kussmaul respirations are deep, rapid breaths that occur as the body attempts to compensate for metabolic acidosis, such as in diabetic ketoacidosis.
Sighing respirations involve intermittent deep breaths between normal breaths and may occur with anxiety or normal lung expansion. Biot breathing consists of clusters of breaths followed by irregular periods of apnea and is often linked to brainstem injury. Apnea is a temporary cessation of breathing, while ataxic breathing is completely irregular and typically indicates severe brainstem dysfunction.
