Ventilatory movements such as regular, deep, or shallow classify breathing patterns.

In Biot's breathing, respiratory rate and depth are irregular, with alternating periods of deep gasping with periods of apnea.

The common cause includes damage to the respiratory center in the brain due to conditions like stroke, head trauma, and spinal meningitis.

Cheyne-Stokes breathing is characterized by a respiratory cycle that begins with slow, shallow breaths, gradually increasing to an abnormal rate and depth. The pattern alternates with breathing, leading to apnea before respiration resumes.

For instance, patients with cardiac failure, hyponatremia, and brain injury exhibit this breathing pattern.

Kussmaul's breathing is abnormally deep and rapid but consistent at pace. The common cause includes respiratory center stimulation due to metabolic acidosis.

Hyperventilation includes increased rate and depth of respirations and may lead to hypocarbia. Anxiety, exercise, and metabolic acidosis are a few causes of hyperventilation.

Hypoventilation is shallow and irregular breaths. It results from an overdose of specific anesthetic agents, prolonged bed rest, or chest splinting to avoid respiratory pain.
