The SATURİSTA Device (SATURİSTA)
Development and Pilot Evaluation of an Artificial Intelligence-Assisted System for Automated Oxygen Flow Regulation: The Saturista 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.

详细说明
The Saturista system is a novel, integrated platform designed to support automated oxygen therapy management through continuous monitoring of oxygen saturation (SpO₂) and real-time decision support. The system combines pulse oximetry-based sensing, wireless data transmission, a cloud-based data infrastructure, and a web-based user interface within a distributed closed-loop control architecture.
In conventional clinical practice, oxygen therapy is typically adjusted manually based on intermittent assessment of oxygen saturation. This approach may delay recognition of physiological deterioration and timely intervention. The Saturista system addresses this limitation by enabling continuous monitoring, automated alarm generation, and centralized visualization of patient data at the nursing station.
The system consists of three main components: (i) a pulse oximetry-based monitoring module, (ii) an embedded device with wireless communication capabilities that regulates oxygen flow via a pneumatic valve mechanism, and (iii) a cloud-based software platform that processes physiological data and provides real-time visualization and alarm management.
This study is designed as a pilot feasibility study conducted in healthy volunteers to evaluate the technical and functional performance of the system. A scenario-based testing protocol will be applied, including baseline monitoring, controlled desaturation through short-duration breathing maneuvers, probe disconnection, and signal recovery. These scenarios simulate common clinical monitoring conditions and allow assessment of system responsiveness and reliability.
The primary outcome measures include the system's ability to detect decreases in SpO₂ and generate appropriate alarms, as well as its capacity to display physiological data in real time. Secondary outcomes include system response time, detection of signal loss, recovery performance, and overall operational stability.
The findings of this study are expected to provide preliminary evidence regarding the feasibility and functional performance of the Saturista system and to inform the design of future clinical studies in patient populations.

研究人群
The study population consists of healthy adult volunteers recruited for a pilot feasibility evaluation of the Saturista system. Participants are individuals without known respiratory or cardiovascular disease and with normal baseline oxygen saturation levels.
The purpose of selecting a healthy population is to assess the technical performance and functional reliability of the system under controlled conditions before clinical testing in patient populations. All participants will undergo a structured, scenario-based testing protocol, including baseline monitoring, controlled desaturation maneuvers within safe physiological limits, probe disconnection, and signal recovery.
This population allows for standardized assessment of the system's ability to monitor SpO₂, generate alarms, display real-time data, and manage signal-related events without the confounding effects of underlying clinical conditions.

Healthy Adult Volunteers (Pilot Feasibility Cohort)
This cohort includes healthy adult volunteers participating in a pilot feasibility study to evaluate the functional performance of the Saturista system. Participants will undergo a structured, scenario-based testing protocol under controlled conditions. The protocol includes baseline monitoring, controlled desaturation through short-duration breathing maneuvers, probe disconnection, and signal recovery. The purpose of this cohort is to assess the system's ability to monitor oxygen saturation (SpO₂), generate alarms in response to predefined threshold changes, display data in real time, and manage signal interruption and recovery. No therapeutic intervention is applied, and all procedures are conducted within safe physiological limits under supervision. |
