SERVO-flow is designed through collaboration with Getinge and showcases a new ventilator that facilitates a seamless move from the intensive care unit (ICU) to a step-down ward. The project aims to strengthen the position of step-down wards by increasing the advancement level of ventilators used outside of the ICU and rethinking their product architecture to meet the needs of physicians, nurses and physiotherapits. The COVID-19 pandemic has accelerated the adoption of high-flow therapy outside of the ICU. It has proven effective in managing respiratory distress, reducing the need for intubation, and providing an intermediate level of care between standard oxygen therapy and mechanical ventilation. Implementing advanced respiratory support in step-down wards can help reduce the load on ICUs by managing patients who do not require intensive care but still need more support than what is provided in general wards. This approach optimizes ICU resources, ensuring that critical care beds are available for the most severe cases. However, step-down wards can receive critically ill patients who have been stable in the ICU for only 2-4 hours, with 30-50% of these patients experiencing deterioration. The high risk of deterioration among recently stabilized ICU patients underscores the need for advanced monitoring solutions to promptly detect and address any decline of a patient’s condition.The future hospital is a dynamic environment where patient mobilization is integrated at every ward level based on the patient’s capabilities. Designing ventilators to support patient mobilization is crucial for recovery, particularly in rebuilding diaphragm strength and overall physical rehabilitation. Early and safe mobilization has been shown to improve outcomes and reduce the duration of mechanical ventilation.In today’s market, there is a mismatch between transport ventilators and those used in step-down wards. Physiotherapists need solutions that can be easily attached to walking aids, as the demand for mobilization is increasing and can outpace available staff. To address this need, SERVO-flow is designed with a new product architecture containing the key components, defined in this thesis, for safe and effective use in various mobilization scenarios. This design project is intended to inspire future ventilator development.
