Despite these periodic breathing problems, I feel great.

Periodic breathing is a normal variation of breathing found in infants less than one year.

An irregular breathing pattern - periodic breathing - is typical for the first few weeks.

As your sleeping body attempts to strike some balance between oxygen and carbon dioxide levels, it falls into periodic breathing.

Periodic breathing is a cycle of decreased breathing, followed by a complete absence of breathing (from three to 15 seconds).

It is a collective term referring to two breathing disorders: Cheyne-Stokes respiration and periodic breathing.

Cheyne-Stokes respiration and periodic breathing are the two regions on a spectrum of severity of oscillatory tidal volume.

Individuals who use medical support systems, such as supplemental oxygen, or who require periodic breathing treatments using powered devices rely on a stable source of electricity.

Apnea & hypopnea detection - Diagnostic components of sleep apnea/hypopnea syndrome and periodic breathing.

This is periodic breathing with recurrent episodes of apnea alternating with episodes of rapid breathing.

Periodic breathing is fairly common at higher altitudes and is not itself a sign of altitude sickness, but it often leaves afflicted individuals feeling worn out upon waking.

The distinction lies in what is observed at the trough of ventilation: Cheyne-Stokes respiration involves apnea (since apnea is a prominent feature in their original description) while periodic breathing involves hypopnea (abnormally small but not absent breaths).

Consequently, at the nadir of periodic breathing, ventilation of the alveolar space may be effectively zero; the easily-observable counterpart of this is failure at that time point of the end-tidal gas concentrations to resemble realistic alveolar concentrations.
