A Dual Closed-Loop Control System for Mechanical Ventilation
Journal of Clinical Monitoring and Computing, 2004Closed-loop mechanical ventilation has the potential to provide more effective ventilatory support to patients with less complexity than conventional ventilation. The purpose of this study was to investigate the effectiveness of an automatic technique for mechanical ventilation.Two closed-loop control systems for mechanical ventilation are combined in ...

Physiological closed-loop control of mechanical ventilation and extracorporeal membrane oxygenation
Biomedizinische Technik, 2017AbstractA new concept is presented for cooperative automation of mechanical ventilation and extracorporeal membrane oxygenation (ECMO) therapy for treatment of acute respiratory distress syndrome (ARDS). While mechanical ventilation is continuously optimized to promote lung protection, extracorporeal gas transfer rates are simultaneously adjusted to ...

Closed-Loop Control of Arterial CO2 in Mechanical Ventilation of Neonates
2022 44th Annual International Conference of the IEEE Engineering in Medicine & Biology Society (EMBC), 2022During mechanical ventilation of the neonate the main goal is to stabilize respiratory function of the often premature lungs. Ventilating the patient without inflicting harm is then the subordinated next goal. Ideally the arterial partial pressure of CO2 lays within a normocapnic range and fluctuations are kept minimal.

Control mechanism for software pipelining on nested loop
Proceedings. Advances in Parallel and Distributed Computing, 2002ILSP (Interlaced inner and outer Loop Software Pipelining) is an efficient algorithm of optimizing operations in the nested loops. To ensure the ILSP has a good time efficiency and a good space efficiency, there must be an efficient nested control mechanism to support the algorithm.

On closed-loop vibrational control of underactuated mechanical systems
Nonlinear Dynamics, 2022This paper discusses vibrational stabilization of a class of single-input, two degree-of-freedom mechanical systems. Considering two different control formulations—position-input and force-input—and both open- and closed-loop control, we find that the sets of attainable equilibrium positions for the unactuated coordinate are identical in every case ...

Age-related changes in open-loop and closed-loop postural control mechanisms
Experimental Brain Research, 1995In an earlier posturographic investigation (Collins and De Luca 1993) it was proposed that open-loop and closed-loop control mechanisms are involved in the regulation of undisturbed, upright stance. In this study, stabilogram-diffusion analysis was used to examine how the natural aging process affects the operational characteristics of these control ...
