Trends in mechanical ventilation: are we ventilating our patients in the best possible way?
Introduction. Even though the concept of mechanical ventilation dates back to the 14th century with V esalius [], it is only in the last century that it has been widely introduced into routine clinical practice.Since their initial appearance, mechanical ventilators have become more sophisticated and expanded their application from the intensive care unit (ICU) to the respiratory medicine ward ...

The Mechanical Ventilator: Past, Present, and Future
The use of ventilatory assistance can be traced back to biblical times. However, mechanical ventilators, in the form of negative-pressure ventilation, first appeared in the early 1800s. Positive-pressure devices started to become available around 1900 and today's typical intensive care unit (ICU) ventilator did not begin to be developed until the 1940s. From the original 1940s ventilators ...
An Introduction to Low-Cost Portable Ventilator Design
Mechanical ventilation is a life-saver in the development of modern ICUs. This paper provides an idea of origin of modern mechanical ventilators. Based on reviewed literature, a simple, easy-to-use and easy-to-build design of low-cost portable ventilator is proposed in this paper. The proposed ventilator prototype is assumed to have better working performance than already available in market ...
Physiologic Basis of Mechanical Ventilation
The primary purpose of mechanical ventilation is to decrease work of breathing. Achieving this goal requires that cycling of the ventilator be carefully aligned with the intrinsic rhythm of a patient's respiratory center output. Problems arise at the point of ventilator triggering, post-trigger inflation, and inspiration-expiration switchover.
Low-Cost, Open-Source Mechanical Ventilator with Pulmonary Monitoring
This paper shows the construction of a low-cost, open-source mechanical ventilator. The motivation for constructing this kind of ventilator comes from the worldwide shortage of mechanical ventilators for treating COVID-19 patients—the COVID-19 pandemic has been striking hard in some regions, especially the deprived ones. Constructing a low-cost, open-source mechanical ventilator aims to ...
Mechanical Ventilation, Past, Present, and Future
Mechanical ventilation (MV) has played a crucial role in the medical field, particularly in anesthesia and in critical care medicine (CCM) settings. MV has evolved significantly since its inception over 70 years ago and the future promises even more advanced technology. In the past, ventilation was provided manually, intermittently, and it was ...
Mechanical Ventilation
Mechanical ventilation is a critical intervention to sustain life in acute or emergent settings, particularly in patients with compromised airways, impaired ventilation, or hypoxemic respiratory failure. This procedure involves applying positive pressure breaths and relies on the airway system's compliance and resistance. Clinicians in critical care units must understand how mechanical ...
The effect of ventilator-associated pneumonia on the prognosis of
Background Mechanical ventilation (MV) is often applied in critically ill patients in intensive care unit (ICU) to protect the airway from aspiration, and supplement more oxygen. MV may result in ventilator-associated pneumonia (VAP) in ICU patients. This study was to estimate the 90-day and 180-day mortalities of ICU patients with VAP, and to explore the influence of VAP on the outcomes of ...
Design and Prototyping of a Low-Cost Portable Mechanical Ventilator
Abstract and Figures. This paper describes the design and prototyping of a low-cost portable mechanical ventilator for use in mass casualty cases and resource-poor environments. The ventilator ...
The Mechanical Lung Ventilator Case Study
The mechanical lung ventilator is intended to ventilate patients in intensive therapy who require mechanical ventilation [].The ventilator proposed for the ABZ 2024 Case Study works in pressure mode, i.e., the respiratory time cycle of the patient is controlled by pressure, and, therefore, this ventilator requires a source of compressed oxygen and medical air readily available in intensive ...
Design and analysis of a mechanical ventilation system based on cams
The cam is changed manually according to the ventilation requirements established by the medical staff and tidal volume, OxygenIP.PE general specifications are shown in Table 1. Figure 2. Mechanical ventilation system OxygenIP.PE: (a) Inspiration phase; (b) Exhalation phase; (c) Isometric view. Table 1.
2019 Year in Review: Patient-Ventilator Synchrony
Abstract. Patient-ventilator synchrony is a popular topic of research on mechanical ventilation. This review puts this research into both contemporary and historical perspective. Five areas of research are described: literature reviews, manual detection of synchrony problems, automated detection of synchrony problems, modes for improving ...
A Low-Cost Portable Mechanical Ventilator—A Conceptual Design
Toward the direction of physically realizing an innovative mechanical ventilator, this paper discusses the idea of the design and fabrication of a reusable, low-cost portable mechanical ventilator. ... This has led to a lot of research and development to be done by engineers in the past few years in order to design such ventilators which can be ...
Recent advances in mechanical ventilation
The process of liberation from mechanical ventilation is becoming more standardized, with evidence supporting daily trials of spontaneous breathing in all suitable mechanically ventilated patients. This article critically reviews the most important recent advances in mechanical ventilation and suggests future directions for further research in ...
2018 Year in Review: Adult Invasive Mechanical Ventilation
Research in the area of adult invasive mechanical ventilation is rich and diverse. With more than 3,200 articles on mechanical ventilation published in 2018, isolating the most relevant literature is a challenge.
