En este trabajo se analizan por espectrometría de masas, según la normativa de la Unión Europea (UE), los sistemas de Venturi de distintas casas proveedoras disponibles en el mercado español. Se evalúa también la tolerancia de los sistemas ante diversas circustancias (cambios de flujo de oxígeno y aumento de resistencias en el sistema). Se ha encontrado que los sistemas fijos se adaptan bien a la normativa, mientras que ninguno de los sistemas variables cumple los requisitos que establece esta normativa, y un sistema (Oxigem variable) es incapaz de dar, para concentraciones del 24–28%, una concentración de O2 por debajo del 31%</p><p id="spar0010" class="elsevierStyleSimplePara elsevierViewall">En conclusión, en nuestro mercado las mascarillas variables no cumplen la normativa UE y una de ellas (Oxigem variable) tiene un rango de error que no permite su uso en la práctica clínica.

Nevertheless, rigorous quality control of their reliability is lacking. In this study we used mass spectrometry to evaluate Venturi systems sold by various companies in Spain. We also studied tolerance under various conditions (changes in oxygen flow and with increased system resistance). Fixed systems were found to comply well with recommendations, whereas none of the variable systems complied. One system (Oxigem Variable) was unable to provide an oxygen concentration below 31% when set to deliver at 24% to 28%. We conclude that the variable masks available in Spain do not comply with European Union recommendations and the range of error of one of them (Oxigem Variable) means it is not clinically useful. Fixed systems were the most reliable ones in our market, and airlife and intersurgical devices were the variable systems that best approximated the reliability of fixed systems</p>" ] ] "bibliografia" => array:2 [ "titulo" => "Bibliografía" "seccion" => array:1 [ 0 => array:2 [ "identificador" => "bibs0005" "bibliografiaReferencia" => array:11 [ 0 => array:3 [ "identificador" => "bib0005" "etiqueta" => "1."
