Advanced Microprocessor-Controlled Mechanical Ventilator: Design, Performance Analysis, and Clinical Evaluation

Abstract

This paper discusses three key aspects of the ventilator's function and design and also its practical application in the healthcare industry. Mechanical ventilation, as a healthcare technique, has undergone great changes in the last century and has become an essential part of every Modern Intensive Care Unit. As such, in this paper, the fundamentals of ventilator design, specifically the engineering of the pneumatic control systems, electronics, and safety control systems, will be described. The current models and working units of ventilators are of prime interest to me. I describe and explain different models: VCV, PCV, CPAP, and BiPAP. In assessing the said topic, the design and build of these devices will be discussed, focusing on the primary requirements, the increasing of the safety of the devices, to improve patient safety, namely effective flow control and monitoring, pressure control, and real-time corrective mechanisms. In the developed countries, the ventilators fitted with ultra-reliable modern devices include control systems and efficient alarm systems. The Performance Criteria for Ventilators shall be to deliver the target tidal volume at a control of ±10% and pressure of ±2 cmH20. High performance, in this case, is the standard in Critical Care with regard to Ventilators. This paper discusses three key aspects of the ventilator's function and design and its practical application in the healthcare industry. Mechanical ventilation, as a healthcare technique, has evolved significantly over the past century and turned into a vital element in every Modern Intensive Care Unit. In this paper, the fundamentals of ventilator design, specifically the engineering of the pneumatic control systems, electronics, and safety control systems, are outlined. Ventilators currently in circulation, both models and working units, are of primary interest to me, and I also describe and explain different models, including VCV, PCV, CPAP, and BiPAP. In this assessment, I describe the design and build of these devices to focus on the primary requirements for increasing the safety of the devices and improving patient safety, i.e., effective flow control and monitoring, pressure control, and real-time corrective mechanisms. In developed countries, ventilators are fitted with ultra-reliable modern devices: ultra-reliable control systems, efficient alarm systems. The Performance Criteria for Ventilators is for the device to deliver the target tidal volume at a control of ±10% and pressure of ±2 cmH20. High Performance, in this case, is the Standard in Critical Care for Ventilators.
