Incidence of hypoxaemia with intravenous fentanyl and midazolam sedation in adult patients undergoing oral surgery procedures
… this study was to investigate the incidence of hypoxaemia (SpO2 ≤94%) in American Society of Anaesthesiologists physical status I & II patients undergoing intravenous sedation with fentanyl and midazolam. The secondary aims included determination of the onset time of hypoxaemic events and …

Predictors of difficult intubation in obstetric cohort of patients: an analysis of the prospective obstetric airway management registry (OBAMR) (substudy – R025/2018)
Abstract Background: Hypoxaemia during tracheal intubation in obstetrics remains a lifethreatening complication. This study aimed to identify common clinical preinduction predictors of difficult intubation. Methods: A retrospective analysis was performed of data pertaining to tracheal intubation in …

Hypoxaemia during tracheal intubation in patients with hypertensive disorders of pregnancy: analysis of data from an obstetric airway management registry
… We compared the prevalence and risk factors for hypoxaemia (SpO2<90%) during induction of general anaesthesia in parturients with and without hypertensive disorders of pregnancy. We hypothesised that hypertensive disorders of pregnancy are associated with desaturation during tracheal intubation. …

Hypoxia and the regulation of host responses to acute bacterial pulmonary infections
… are frequently complicated by systemic hypoxaemia and, in the context of acute respiratory distress syndrome (ARDS), inappropriately prolonged neutrophilic inflammation. This combination of acute hypoxaemia and persistent inflammatory response carries significant morbidity and mortality. …

An exploratory study of neuropsychological impairment, driving performance, and sleepiness in obstructive sleep apnoea and chronic obstructive pulmonary disease
… the contribution of sleep fragmentation and hypoxaemia to poor performance and neuropsychological decline.

Illuminating a neglected population: epidemiological and clinical features of silicosis and tuberculosis among former gold miners from Lesotho
… of silicosis, tuberculosis, and associated hypoxaemia to better understand the predictive effects of comorbidity, the determinants of severity, and health care implications. Methods Three separate but inter-related sub-studies (two cross-sectional and one case series) were conducted from a …

Low-dose thiafentanil in combination with azaperone alone or azaperone and medetomidine for the immobilization of African buffalo (Syncerus caffer)
… of opioid and at only a quarter of the cost. Hypoxaemia was a concern in both combinations and resulted mainly from decreased pulmonary oxygen diffusion rather than hypoventilation. Importantly, despite respiratory rates and partial pressure of carbon dioxide (PaCO2) values being within the …

A review of the use of inhaled nitric oxide in the PICU at Red Cross Children's Hospital, 2011-2015: A retrospective cohort study
… often employed as rescue therapy for refractory hypoxaemia in acute respiratory distress syndrome (ARDS) and pulmonary hypertension (PHT) following cardiac surgery. Objectives: To describe the response to treatment with iNO. Secondary observations were deaths, comorbidities of the patients …

Incidence and Pathogenesis of Acute Lung Injury and the Acute Respiratory Distress Syndrome in Humans
… neutrophilic pulmonary inflammation, refractory hypoxaemia and diffuse alveolar damage. This work reports on the first UK based prospective study of the incidence and longer term mortality of ALI/ARDS in a general intensive care unit. Results reveal significant under recognition of this …

Perioperative comparison of the agreement between a portable fingertip pulse oximeter vs. a conventional bedside pulse oximeter in adult patients (COMFORT trial)
… with conventional pulse oximeters during hypoxaemia. Skin tones do not appear to adversely affect measurements.

Physiological responses of wild antelope to exercise training as a prospective treatment to prevent capture myopathy
… groups. The data also confirmed the severe hypoxaemia that is caused by the opioid immobilisation drugs. This is the first study showing that wild antelope can be successfully exercise trained, which led to physiological adaptations resulting in improved fitness. Whether this training …

Αιμοδυναμικές και αναπνευστικές επιδράσεις της θειϊκής πρωταμίνης σε σχέση με την οδό και τον ρυθμό χορήγησης: Πειραματική μελέτη
… infusions proved the most «benign» regarding hypoxaemia and pulmonary mechanics alterations. In view of these findings, it is clear that no particular site or rate of injection could be recommended as absolutely safe. Adequate dilution and slow administration via a peripheral vein seems to be …

Hypoxia and vascular nitric oxide bioavailability: Hypoximplications for the pathophysiology of high-altitude illness

Endotype Discovery in Acute Respiratory Distress Syndrome

Redox regulation of vascular NO bioavailability during hypoxia: implications for oxygen transport and exercise performance
… in acute hypoxia is driven by the magnitude of hypoxaemia and an accelerated rate of cerebral and muscle deoxygenation. Molecular biomarkers of endothelial function in particular, NO2• and CAMs, are also influenced by hypoxia and may contribute to the reduction in O2peak. IH may be used to …

Cathepsin S as a mediator of acute lung inflammation
… non-cardiogenic oedema and refractory hypoxaemia, which can be triggered by numerous pro-inflammatory stimuli including pneumonia, sepsis and gastric acid aspiration. The inciting injury may be further exacerbated by the application of supportive mechanical ventilation and the …

Investigations into the immunology, physiology and epidemiology of pertussis
