Soluzioni per la ventilazione naturale e precetti igienici nell’edilizia ospedaliera tra Ottocento e Novecento
2016
La ventilazione, il riscaldamento e raffrescamento, il soleggiamento divennero, tra Ottocento e Novecento, strumenti imprescindibili per garantire la salubrità dell’aria e degli ambienti, sia nel caso di risanamento di edifici esistenti, sia nella realizzazione di nuove costruzioni. La tipologia degli ospedali era, al pari delle scuole, teatri, mercati quella in cui i sistemi di ventilazione finalizzati all’igiene dell’aria erano studiati con più accuratezza. Si ricorreva ad ingegnosi espedienti che consentivano di mantenere nello stabilimento sanitario quelle condizioni che garantissero il comfort ambientale, evitando l’entrata di aria dai padiglioni delle malattie infettive; particolare i…
Protective ventilation with high versus low positive end-expiratory pressure during one-lung ventilation for thoracic surgery (PROTHOR): study protoc…
2019
Background: Postoperative pulmonary complications (PPC) may result in longer duration of in-hospital stay and even mortality. Both thoracic surgery and intraoperative mechanical ventilation settings add considerably to the risk of PPC. It is unclear if one-lung ventilation (OLV) for thoracic surgery with a strategy of intraoperative high positive end-expiratory pressure (PEEP) and recruitment maneuvers (RM) reduces PPC, compared to low PEEP without RM. Methods: PROTHOR is an international, multicenter, randomized, controlled, assessor-blinded, two-arm trial initiated by investigators of the PROtective VEntilation NETwork. In total, 2378 patients will be randomly assigned to one of two diffe…
Ski economy and physiological responses while double poling : curved vs. straight poles
2015
Christina Mishica (2015). Ski economy and physiological responses while double poling: curved vs. straight poles. Department of Biology of Physical Activity, University of Jyväskylä, Master’s Thesis in Exercise Physiology. 57 pp. Introduction. Double poling (DP) is commonly used in cross country skiing (XC). It is becoming more and more popular and in some competitions it is the exclusive technique. Ski poles allow a skier to apply power and force to the snow and their composition and design have a significant effect on performance. Different pole lengths and cross sections are some of the differences that have been tested. Advancements in equipment will continue to be introduced so it is i…
Sigh in patients with acute hypoxemic respiratory failure and acute respiratory distress syndrome: the PROTECTION pilot randomized clinical trial
2021
Background: Sigh is a cyclic brief recruitment manoeuvre: previous physiological studies showed that its use could be an interesting addition to pressure support ventilation to improve lung elastance, decrease regional heterogeneity and increase release of surfactant. Research question: Is the clinical application of sigh during pressure support ventilation (PSV) feasible? Study design and methods: We conducted a multi-center non-inferiority randomized clinical trial on adult intubated patients with acute hypoxemic respiratory failure or acute respiratory distress syndrome undergoing PSV. Patients were randomized to the No Sigh group and treated by PSV alone, or to the Sigh group, treated b…
Pressure support ventilation + sigh in acute hypoxemic respiratory failure patients: Study protocol for a pilot randomized controlled trial, the PROT…
2018
Background Adding cyclic short sustained inflations (sigh) to assisted ventilation yields optimizes lung recruitment, decreases heterogeneity and reduces inspiratory effort in patients with acute hypoxemic respiratory failure (AHRF). These findings suggest that adding sigh to pressure support ventilation (PSV) might decrease the risk of lung injury, shorten weaning and improve clinical outcomes. Thus, we conceived a pilot trial to test the feasibility of adding sigh to PSV (the PROTECTION study). Methods PROTECTION is an international randomized controlled trial that will be conducted in 23 intensive care units (ICUs). Patients with AHRF who have been intubated from 24 h to 7 days and under…

Effects of non invasive ventilation on left and right hemodynamic parameters during acute respiratory failure secondary to COPD exacerbation

Supraclavicular approach is an easy and safe method of subclavian vein catheterization even in mechanically ventilated patients: Analysis of 370 atte…
2009
BACKGROUND: Central venous catheters are commonly inserted for hemodynamic monitoring, volume monitoring, administration of medications, long-term total parenteral nutrition, access for renal replacement therapy, cardiopulmonary resuscitation, and difficult peripheral catheterization. The primary outcome of this study was to define venipuncture, catheterization and entire procedure success rates, and finally complication rate of subclavian venous catheterization via the supraclavicular approach with special focus on mechanically ventilated patients. The secondary outcome was to potentially make recommendations regarding this technique of central venous catheterization in mechanically ventil…
Bilevel heat exchanger network synthesis with an interactive multi-objective optimization method
2012
Abstract Heat exchanger network synthesis (HENS) has been an active research area for more than 40 years because well-designed heat exchanger networks enable heat recovery in process industries in an energy- and cost-efficient manner. Due to ever increasing global competition and need to decrease the harmful effects done on the environment, there still is a continuous need to improve the heat exchanger networks and their synthesizing methods. In this work we present a HENS method that combines an interactive multi-objective optimization method with a simultaneous bilevel HENS method, where the bilevel part of the method is based on grouping of process streams and building aggregate streams …
