Periodic Breathing during Incremental Exercise [PDF]
Annals of the American Thoracic Society, 2017 Abstract Periodic breathing during incremental cardiopulmonary exercise testing is a regularly recurring waxing and waning of tidal volume due to oscillations in central respiratory drive. Periodic breathing is a sign of respiratory control system instability, which may occur at rest or during exercise.

Quantification of periodic breathing in premature infants. [PDF]
Physiol Meas, 2015 Periodic breathing (PB), regular cycles of short apneic pauses and breaths, is common in newborn infants. To characterize normal and potentially pathologic PB, we used our automated apnea detection system and developed a novel method for quantifying PB. We identified a preterm infant who died of sudden infant death syndrome (SIDS) and who, on review of

Postanesthetic Apnea and Periodic Breathing in Infants
Anesthesiology, 1986 We designed this prospective study to determine the incidence of perioperative apnea and/or periodic breathing in infants undergoing general anesthesia for inguinal herniorrhaphy in the first year of life.

Roles of periodic breathing and isocapnic buffering period during exercise in heart failure. [PDF]
Eur J Prev Cardiol, 2020 In heart failure, exercise – induced periodic breathing and end tidal carbon dioxide pressure value during the isocapnic buffering period are two features identified at cardiopulmonary exercise testing strictly related to sympathetic activation.

Infant periodic breathing and apneic threshold. [PDF]
Physiol RepAbstractA mathematical model was proposed to predict the role played by apneic threshold in periodic breathing in preterm infants. Prior models have mainly applied linear control theory which predicted instability but could not explain sustained periodic breathing.

Enhanced expiratory rebreathing space for high loop gain sleep apnea treatment
Frontiers in Sleep, 2023 The pathophysiology of sleep apnea goes beyond anatomic predisposition to airway collapse and includes additional factors such as arousal threshold and loop gain. High loop gain is a prominent feature in central and complex sleep apnea (with a mixture of

Neuromodulatory Support for Breathing and Cardiovascular Action During Development
Frontiers in Pediatrics, 2021 Neonatal survival requires precise control of breathing and cardiovascular action, with fatal consequences or severe injury without support. Prematurity presents multiple opportunities to disrupt cardiorespiratory regulation, leading to expressions of ...

Idiopathic central sleep apnea with periodicity presenting as Cheyne-Stokes breathing – Case report [PDF]
Romanian Journal of Neurology, 2022 Cheyne-Stokes breathing (CSB) is described by a cyclic variation in breathing with periods of central apneas or hypopneas alternating with periods of hypopneas in a gradual waxing and waning manner.
