Ventilation workshop - a new concept

2000

The use of simulator technology to practise crisis resource management or to train standardised procedures in anaesthesia is a proved concept, although its setup in clinical practice is still in progress. To get a better understanding of the complex pathophysiological and clinical relations in the pulmonary system and the kind of alterations that could be induced by changing the ventilation of an intensive care unit patient, we modified the current concept. We created a workshop, which employs more than just the simulator training in the classical sense. During this workshop the participants attend one patient from admission to an emergency room, until discharge from an intensive care unit …

Predicting critical illness on initial diagnosis of COVID-19 based on easily-obtained clinical variables: Development and validation of the PRIORITY …

2020

ABSTRACTObjectivesCurrently available COVID-19 prognostic models have focused on laboratory and radiological data obtained following admission. However, these tests are not available on initial assessment or in resource-limited settings. We aim to develop and validate a prediction model, based on clinical history and examination findings on initial diagnosis of COVID-19, to identify patients at risk of critical outcomes.MethodsWe used data from the SEMI-COVID-19 Registry, a nationwide multicenter cohort of consecutive patients hospitalized for COVID-19 from 132 centers in Spain. Clinical signs and symptoms, demographic variables, and medical history ascertained at hospital admission were sc…

Perioperative Adverse Events in Obstructive Sleep Apnea and Use of Noninvasive Mechanical Ventilation: Key Topics and Clinical Implications

2016

Obstructive sleep apnea (OSA) is a common public health care problem and, yet, the perioperative management of OSA remains inadequate. Patients affected by this condition are prone to early postoperative complications, in part due to the negative effects of sedative, analgesic, and anesthetic agents on pharyngeal tone and arousal responses to hypoxia, hypercapnia, and obstruction. The use of opioids may also contribute to late adverse events, mainly by suppressing the rapid eye movement phase of sleep. As a result, preoperative screening of patients at high risk of OSA, as well as the implementation of a perioperative strategy to reduce the risk of complications, should lead to early periop…

2002

Uno de los principales objetivos en el diseño de los nuevosmodos ventilatorios usados en unidades de reanimación y cuidados críticos es elconseguir abolir o minimizar el trabajo respiratorio adicional o impuesto (WOBad) porel propio sistema de ventilación. La ventilación con presión de soporte (PSV) consiguela compensación del WOBad mediante la aplicación de una presión inspiratoriapreseleccionada, con los inconvenientes que ello puede acarrear de sobrecompensacióno infracompensación en función del flujo espontáneo del enfermo en cada momento. Laventilación con compensación automática del tubo endotraqueal (ATC), nace con elúnico objetivo de compensar el WOBad. Para ello aplica un soporte d…

Specific Features of the Coagulopathy Signature in Severe COVID-19 Pneumonia

2021

Rationale: COVID-19 displays distinct characteristics that suggest a unique pathogenesis. The objective of this study was to compare biomarkers of coagulopathy and outcomes in COVID-19 and non-COVID-19 patients with severe pneumonia.Methods: Thirty-six non-COVID-19 and 27 COVID-19 non-immunocompromised patients with severe pneumonia were prospectively enrolled, most requiring intensive care. Clinical and biological characteristics (including plasma biomarkers of coagulopathy) were compared.Results: At similar baseline severity, COVID-19 patients required mechanical ventilation (MV) for significantly longer than non-COVID-19 patients (p = 0.0049) and more frequently developed venous thrombot…

Optimization of ventilation system in the open office space

2018

The paper presents the results of study into the air parameters in open space offices. As office workers spend about 1/3 of the day in such spaces, it is important to provide them with the right climate comfort, and that is determined, most importantly, by: the temperature and humidity of the air, quality of the air, and the concentration of CO2. Two objects of study were selected - both of them open space facilities, each with a different intensity of use. In the course of study, measurements were taken on the basis of which the distributions of temperature, humidity, and concentrations of CO2 in the entire volume of the space were determined. Also the empirical coefficients of CO2 emissio…

Sevoflurane Impairs Cerebral Blood Flow Autoregulation in Rats: Reversal by Nonselective Nitric Oxide Synthase Inhibition

2005

UNLABELLED In this study, we investigated the effects of 1.0 and 2.0 minimum alveolar anesthetic concentration (MAC) sevoflurane on cerebral blood flow (CBF) autoregulation before and after nonselective inhibition of nitric oxide (NO) synthase in rats. Rats were randomly assigned as follows: Group 1 (n = 8): 1.0 MAC sevoflurane; Groups 2 and 3 (n = 8 per group): 2.0 MAC sevoflurane. Assessment of autoregulation within a mean arterial blood pressure range of 140-60 mm Hg was performed by graded hemorrhage before and after administration of l-arginine methyl ester (l-NAME, 30 mg/kg IV, Groups 1 and 2) or during hypocapnia (Group 3). In 10 additional animals, brain tissue NO(2)(-) concentratio…

Predictors of poor prognosis in healthy, young, individuals with SARS-CoV-2 infections.

2021

OBJECTIVES: To identify predictors of poor prognosis in previously healthy young individuals admitted with COVID-19. METHODS: We studied a cohort of patients hospitalized with COVID-19 disease. All patients without comorbidities, no usual treatments and =65years old were selected from an international registry (HOPE-COVID-19, NCT04334291). We focused on baseline variables-symptoms and signs at admission-to analyze risk factors for poor prognosis. The primary endpoint was a composite of major adverse clinical events during hospitalization including mortality, mechanical ventilation, high flow nasal oxygen therapy, prone, sepsis, SIRS, and embolic events. RESULTS: Overall, 773 healthy young p…
