UNLABELLED BACKGROUND Hyperventilation may be used to hasten recovery from general anesthesia with potent inhaled anesthetics. However, its effect may be less pronounced with the newer, less soluble agents, and it may result in rehypnotization if subsequent hypoventilation occurs because more residual anesthetic will be available in the body for redistribution to the central nervous system. ...

Abstract Introduction Pediatric sleep-related hypoventilation is a clinical pattern in which ventilatory insufficiency occurs the setting of either severe OSA (obstructive hypoventilation) or obesity (sleep related hypoventilation). We are reporting case describing management overlapping obstructive due to uncontrolled and pediatric syndrome. Report case(s) The patient full term African America...

Central hypoventilation syndrome (CHS) is a rare condition characterized by hypoventilation during sleep, reduced ventilatory responsiveness to CO(2) and O(2), impaired perception of air hunger, and autonomic abnormalities. Neural impairments accompany the condition, including structural injury, impaired cerebral autoregulation, and dysfunctional autonomic control. The hypoventilation may induc...

BACKGROUND Pulse oximetry is a widely accepted procedure for ventilatory monitoring during gastrointestinal endoscopy, but this method provides an indirect measurement of the respiratory function. In addition, detection of abnormal ventilatory activity can be delayed, especially if supplemental oxygen is provided. Capnography offers continuous real-time measurement of expiratory carbon dioxide....

Diaphragm pacing is an alternative to mechanical ventilation in patients with high cervical cord damage (>C4 dermatome). It brings clinical benefits and reduces health costs [1–3]. It is also indicated in certain cases of central hypoventilation [4]. Two types of diaphragm pacing devices are commercially available. With intrathoracic phrenic stimulation, electrodes are implanted around the phre...

Chronic hypoventilation due to injury to the brain stem respiratory center or high cervical cord (above the C3 level) can result in dependence to prolonged mechanical ventilation with tracheostomy, frequent nosocomial pneumonia, and prolonged hospitalization. Diaphragm pacing through electrical stimulation of the phrenic nerve is an established treatment for central hypoventilation syndrome. We...

Complex respiratory events, which may have a detrimental effect on both quality of sleep and control of nocturnal hypoventilation, occur during sleep in patients treated by non-invasive ventilation (NIV). Among these events are patient-ventilator asynchrony, increases in upper airway resistance with or without increased respiratory drive, and leaks. Detection of these events is important in ord...

Objectives—Neuropsychological investigations have shown a degree of cognitive dysfunction in a proportion of nondemented patients with ALS. Respiratory muscle weakness in ALS can lead to nocturnal hypoventilation, resulting in sleep disturbance and daytime somnolence. Sleep deprivation of this type may cause impairments in cognitive function, but this has not been formally evaluated in ALS. Met...

BACKGROUND A correlation has been observed between obstructive sleep events and sleep quality. The aim of the study was to assess if there is also a correlation between nocturnal hypoxemia and hypercapnia and sleep efficiency and sleep fragmentation in children. METHODS Nocturnal pulse oximetry (S(pO(2))) and transcutaneous carbon dioxide (P(tcCO(2))) recordings with simultaneous actigraphy ...
