Biological consequences of oxygen desaturation and respiratory effort in an acute animal model of obstructive sleep apnea (OSA).
BACKGROUND An animal model mimicking all the factors involved in obstructive sleep apnea (OSA) is useful for investigating mechanisms because the associated comorbidity usually present in such patients is an important limitation. AIM To test the hypothesis that hypoxia/normoxia and respiratory effort have different effects on the induction of inflammatory response and endothelial dysfunction ...
متن کاملEvaluating predictions of critical oxygen desaturation events.
This paper presents a new approach for evaluating predictions of oxygen saturation levels in blood ( SpO2). A performance metric based on a threshold is proposed to evaluate SpO2 predictions based on whether or not they are able to capture critical desaturations in the SpO2 time series of patients. We use linear auto-regressive models built using historical SpO2 data to predict critical desa...
متن کاملFatal respiratory events caused by zanamivir nebulization.
To the Editor—GlaxoSmithKline was very concerned to learn of the fatality of a 25-year-old pregnant woman with severe H1N1 influenza A following nebulized administration by means of mechanical ventilation of zanamivir solution, described in the letter by Kiatboonsri et al [1]. This solution had been made by the treating hospital pharmacy from the lactose powder formulation of zanamivir, markete...
متن کاملAcoustic Breath Detection and Classification: Modeling Respiratory Events
A continuation of research into modeling airway events of patients undergoing sedation is described. Sounds recorded at the trachea were recorded and separated by means of a threshold algorithm. The threshold was determined by the expectation maximization algorithm on filtered data. A comparison between the respiratory rate of the threshold algorithm and that of the direct airflow measure is do...
متن کاملNon-Invasive detection of respiratory effort-related arousals (REras) by a nasal cannula/pressure transducer system.
STUDY OBJECTIVES The published AASM guidelines approve use of a nasal cannula/pressure transducer to detect apneas/hypopneas, but require esophageal manometry for Respiratory Effort-Related Arousals (RERAs). However, esophageal manometry may be poorly tolerated by many subjects. We have shown that the shape of the inspiratory flow signal from a nasal cannula identifies flow limitation and eleva...
