Introduction: The prevalence of obesity is continually increasing worldwide, which increases the incidence of obesity hypoventilation syndrome (OHS) and its consequent mortality.
Methods: We reviewed the therapy mode, comorbidity
1. Hypoventilation of one lobe of lung was studied in open-chest anaesthetized dogs. Lobar blood flow, pulmonary-artery pressure and gas exchange were measured, the latter from breath-by-breath analysis with a mass spectrometer. 2. Hypoventilation of the lobe by reducing the respiratory pump stroke
Blood pressure and pulse rate in response to administered adrenaline and acetylcholine during hypoventilation were studied in urethane-anaesthetized rats. Hypoventilation was induced by decreasing the stroke volume of artificial ventilation from 1 ml/100 g to 0.3 ml/100 g. There was a significant

Obstructive sleep apnea (OSA) is a known risk factor for atrial fibrillation (AF) that is principally driven by left atrial enlargement. The impact of hypoventilation caused by obesity-induced hypoventilation syndrome (OHS) on left atrial diameter has not been examined. We investigated
It is known that prostaglandin E1 (PGE1) is a potent vasodilator and improves red cell deformability. Single lung-ventilation sometimes occurs under lung transplantation, lung cancer surgery and traumatic pneumonectomy, and may result in increased pulmonary resistance, right heart failure and severe
This study aimed to determine the cardiovascular responses during a prolonged exercise with voluntary hypoventilation (VH). 7 men performed 3 series of 5-min exercise at 65% of normoxic maximal O (2) uptake under 3 conditions: (1) normal breathing (NB) in normoxia (NB (0.21)), (2) VH in normoxia (VH
Stroke is one of the leading causes of death and long-term disability worldwide.[1][2] As medical management advances, the incidence and mortality rate of stroke declines, with the majority of strokes presenting as ischemic strokes vs. hemorrhagic strokes. As such, the focus of this article will be
Central alveolar hypoventilation disorders denote conditions resulting from underlying neurologic disorders affecting the sensors, the central controller, or the integration of those signals leading to insufficient ventilation and reduction in partial pressures of oxygen. We report a patient who
We describe a case of a 21-year-old man with mitochondrial myopathy, encephalopathy, lactic acidosis and stroke-like episodes (MELAS) who presented with hypoxic ventilatory depression. He had chronic hypoventilation, which was not explained by weakness of respiratory muscles. His hypercapnic
Central alveolar hypoventilation (CAH) syndrome is a clinical condition that is characterized by the loss of automatic breathing, particularly during sleep. Most forms in adults are caused by brainstem ischemia, mass, infection, demyelinating disease, or anoxic-ischemic damage. We present a case of
Passive motion of lower extremities (PMLE) elicits significant increases in alveolar ventilation (V A) in awake children with congenital central hypoventilation syndrome (CCHS), who have absent or near absent ventilatory responses to hypercapnia. We hypothesized that PMLE would improve V A during
The first polysomnographic recordings with concomitant monitoring of cardiocirculatory parameters demonstrated that obstructive apneas arising during sleep are accompanied by a marked increase in pulmonary and systemic arterial pressure and severe alveolar hypoventilation. Apneas also may give rise
OBJECTIVE
To evaluate the cardiorespiratory effects of IV administration of propofol (4 mg/kg), ketamine hydrochloride and propofol (2 mg/kg each; K-P), or ketamine hydrochloride (5 mg/kg) and diazepam (0.2 mg/kg; K-D) before and after induction of anesthesia (IoA) in dogs sedated with acepromazine
OBJECTIVE
To quantitate the effects of desflurane and mode of ventilation on cardiovascular and respiratory functions and identify changes in selected clinicopathologic variables and serum fluoride values associated with desflurane anesthesia in horses.
METHODS
6 healthy adult horses.

Horses
OBJECTIVE
To investigate the influence of a dexmedetomidine constant rate infusion (CRI) in horses anaesthetized with isoflurane.
METHODS
Prospective, randomized, blinded, clinical study.
METHODS
Forty adult healthy horses (weight mean 491 ± SD 102 kg) undergoing elective surgery.
