Cloud Computing: de la virtualización de aplicaciones y de escritorio, a la virtualización de servidores

Las compañías y usuarios están migrando sus servicios de información a soluciones de cloud computing o cómputo en la nube; a través de éste, los servicios informáticos se gestionan a través de la Internet, con lo que es posible consumirlos de manera similar a como se usa la electricidad o el teléfono.Una de las tecnologías que ha favorecido el desarrollo audaz de los servicios de nube es la virtualización en sus diferentes versiones: la virtualización de servidores es un área general que se complementa y hace uso de técnicas más particulares como las de virtualización de aplicaciones y de escritorio.Existen herramientas comerciales para que cualquier organización implemente servicios de virtualización en sus operaciones internas, aunque la implementación de estos servicios es independiente de los servicios de nube, existe una fuerte vinculación entre ambas, y la implementación de la virtualización facilita la incorporación futura a la nube.En el Instituto Tecnológico de la Laguna se está desarrollando un proyecto de virtualización de servidores a través de Microsoft Hyper-V, se espera determinar las ventajas de esta herramienta y de los ambientes virtualizados en general.Palabras clave: Cómputo en la nube, Hyper-V, Servidores, Virtualización

Bronchoscopist's perception of the quality of the single-use bronchoscope (Ambu aScope4™) in selected bronchoscopies: a multicenter study in 21 Spanish pulmonology services

Background: The disposable bronchoscope is an excellent alternative to face the problem of SARS-CoV-2 and other cross infections, but the bronchoscopist’s perception of its quality has not been evaluated. Methods: To evaluate the quality of the Ambu-aScope4 disposable bronchoscope, we carried out a cross-sectional study in 21 Spanish pulmonology services. We use a standardized questionnaire completed by the bronchoscopists at the end of each bronchoscopy. The variables were described with absolute and relative frequencies, measures of cen‑ tral tendency and dispersion depending on their nature. The existence of learning curves was evaluated by CUSUM analysis. Results: The most frequent indications in 300 included bronchoscopies was bronchial aspiration in 69.3% and the median duration of these was 9.1 min. The route of entry was nasal in 47.2% and oral in 34.1%. The average score for ease of use, image, and aspiration quality was 80/100. All the planned techniques were performed in 94.9% and the bronchoscopist was satisfed in 96.6% of the bronchoscopies. They highlighted the portability and immediacy of the aScope4TM to start the procedure in 99.3%, the possibility of taking and storing images in 99.3%. The CUSUM analysis showed average scores>70/100 from the frst procedure and from the 9th procedure more than 80% of the scores exceeded the 80/100 score

We use a standardized questionnaire completed by the bronchoscopists at the end of each bronchoscopy. The variables were described with absolute and relative frequencies, measures of central tendency and dispersion depending on their nature. The existence of learning curves was evaluated by CUSUM analysis. Results: The most frequent indications in 300 included bronchoscopies was bronchial aspiration in 69.3% and the median duration of these was 9.1 min.

They highlighted the portability and immediacy of the aScope4TM to start the procedure in 99.3%, the possibility of taking and storing images in 99.3%. The CUSUM analysis showed average scores > 70/100 from the first procedure and from the 9th procedure more than 80% of the scores exceeded the 80/100 score. Conclusions: The aScope4™ scored well for ease of use, imaging, and aspiration. We found a learning curve with excellent scores from the 9th procedure. Bronchoscopists highlighted its portability, immediacy of use and the possibility of taking and storing images
