Non-invasive ventilation in the weaning process.

PubMed (2008)

Miguel Ferrer

Patients with chronic airflow obstruction and difficulty in weaning from mechanical ventilation are at increased risk for intubation-associated complications and mortality because of prolonged invasive mechanical ventilation. Non-invasive ventilation (NIV) may avert most of the pathophysiologic mechanisms associated with weaning failure in these patients. Several randomised controlled trials have shown that the use of NIV in order to advance extubation in difficult patients can result in reduced periods of endotracheal intubation, complication rates and survival. The published data with the outcome as a primary variable are nearly exclusively from patients who had pre-existing lung disease. In addition, the patients were hemodynamically stable, with a normal level of consciousness, no fever and a preserved cough reflex. The use of NIV in the management of respiratory failure after extubation did not show clinical benefits, although clinical trials included a small proportion of chronic respiratory patients. In contrast, NIV immediately after extubation is effective in avoiding respiratory failure after extubation in patients at risk for this complication, particularly those with chronic respiratory disorders and hypercapnic respiratory failure.

Diseño y manufactura de ortesis dinámica para mano mediante el modelado por deposición fundida (MDF)

Revista de Ciencias de la Salud (2019)

Miguel Guandulay-Alcázar Reynaldo Ledesma-Jaime Miguel Ferrer Gabriela Ramos-Lázaro

Currently a large number of hand injuries occur in the Mexican population, mainly caused by accidents at work and in sports activities. To help the population have access to a brachiopalmar rehabilitation, In this work it was proposed to develop a rehabilitative prototype “dynamic hand orthosis” to address the main pathologies that affect our society (fractures, dislocations, sprains, tendonitis and sx of the carpal tunnel). The design was analyzed in a finite element for its validation, having a safety factor of 2.6 and a maximum tension of 12.84 MPa below the ABS elastic limit, Manufacturing was done using a 3D printer with the ABS filament. This orthosis has an extensor finger attachment composed of hammocks, one for each finger. Due to its universal design, it can be used for both hands only by exchanging the extension of the thumb.

An in-vitro study to evaluate high-volume low-pressure endotracheal tube cuff deflation dynamics

Minerva Anestesiologica (2019)

Joan Daniel Martí Gianluigi Li Bassi Valentina Isetta Miguel R Lazaro Eli Aguilera-Xiol

High-volume low-pressure (HVLP) endotracheal tube (ETT) cuffs for critically ill patients often deflate during the course of mechanical ventilation. We performed an in-vitro study to comprehensively assess HVLP cuff deflation dynamics and potential preventive measures.We evaluated 24-hour deflation of seven HVLP cuffs of cylindrical or tapered shape, and made of polyvinylchloride or polyurethane. Experiments were performed within a thermostated chamber set at 37 °C. In the first stage of experiments, the cuff pilot balloon valve was not manipulated. The cuff internal pressure was assessed hourly for 24 hours, via a linear position sensor which monitored cuff deflation displacements. Then, we re-evaluated cuff deflation of the worst-performing ETT cuffs with the cuff pilot balloon valve sealed. Finally, we inflated ETT cuffs within an artificial trachea to evaluate deflation dynamics during mechanical ventilation.Initial tests showed an exponential decrease in cuff internal pressure in five out of seven cuffs. Cuffs of cylindrical shape and made of polyurethane demonstrated the fastest deflation rates (P<0.050 vs. cuffs of conical shape and made of polyvinylchloride). When the cuff pilot balloon valve was not sealed, the internal cuff pressure deflation rate differed significantly among ETTs (P=0.005). Yet, upon sealing the cuff pilot balloon valve and during mechanical ventilation, cuff deflation rates decreased (P<0.050).In controlled in-vitro settings, ETT cuffs consistently deflate over time, and the cuff pilot balloon valve plays a central role in this occurrence. Deflation rate decreases when cuffs are inflated within a plastic artificial tracheal model and mechanical ventilation is activated.

Manufactura de bicicleta de bambú con transmisión de engranes

Revista del Diseño Innovativo (2019)

Miguel Ferrer Gabriela Ramos-Lázaro Miguel Guandulay-Alcázar Arturo Ortíz-Roa

The present project deals with the construction of a bicycle with a Bamboo structure, a cultivation plant preferably in the southwest of Mexico, however a bamboo cultivated in the Mexican Bajío was used. A transmission based on helical gears was also included, replacing the traditional transmission chain. Solidworks modeling was performed as well as finite element analysis to quantify bicycle safety factors as well as Von Mises efforts. Regarding the assembly and construction of the bamboo bicycle, different cuts of the plant's rods were made to adapt them to the tubular parts of the bicycle frame, in addition to the handlebar. The transmission was assembled with helical gears by coupling them with a power transmission shaft. Also tests were done, already armed the bike, both resistance and speed. And considering testing the transmission with gears.
