The SATURİSTA Device

This study aims to evaluate the functional performance and feasibility of the Saturista system, a novel device designed for automated oxygen flow regulation based on continuous monitoring of oxygen saturation (SpO₂). The system integrates real-time physiological monitoring, wireless data transmission, and centralized visualization to support timely detection of oxygen desaturation and clinical decision-making. A pilot feasibility study will be conducted in healthy volunteers using a scenario-based protocol, including baseline monitoring, controlled desaturation, probe disconnection, and signal recovery. The primary objective is to assess the system's ability to generate alarms in response to changes in SpO₂ and to display data in real time. Secondary objectives include evaluation of response time, signal management, and overall system stability.

Comparison of Physiological Effects of Two High-Flow Tracheal Oxygen Versus T-Piece During Spontaneous Breathing Trials

Spontaneous breathing trials (SBT) are essential for assessing extubation tolerance, yet optimal approaches are debated. High-flow nasal oxygen offers benefits like precise oxygen delivery, flow-related positive end-expiratory pressure generation and improved lung function. While high-flow tracheal oxygen can also be used as an SBT method, it has reduced physiological effects due to bypassing the upper airway with a more open circuit. To enhance this limitation, investigators developed a modified high-flow tracheal oxygen tube with a smaller expiratory end diameter to increase expiratory resistance and airway pressure. This is a prospective randomized crossover study that aims to compare the physiological effects of standard and modified high-flow tracheal oxygen versus T-piece during SBT.

Comparison of Physiological Effects of Two Types of High-Flow Oxygen Therapy in Tracheostomized Patients

High-flow nasal oxygen therapy offers benefits like precise oxygen delivery, flow-related positive end-expiratory pressure generation and improved lung function. High-flow oxygen therapy can be applied via tracheostomy as high-flow tracheal oxygen. While high-flow tracheal oxygen has been used to facilitate weaning, it has diminished physiological effects due to bypassing upper airways. To enhance its effectiveness, researchers developed a modified high-flow tracheal oxygen tube with a smaller expiratory end diameter to increase airway resistance and pressure. This is a prospective randomized crossover study that aims to compare the physiological effects of standard and modified high-flow oxygen therapy in tracheostomized patients.
