Principles of mechanical ventilation--a critical review
1De Montfort University, Faculty of Health and Life Sciences, School of Nursing and Midwifery, Leicester, UK.
Abstract:
This article is the first of a two-part review focusing on mechanical ventilation, with particular emphasis on non-invasive ventilation when managing patients suffering from respiratory failure. This article explores the principles underpinning artificial ventilation, explains the difference between positive and negative pressure ventilation, and differentiates between invasive and non-invasive modes of ventilation. Finally it examines the various operational features, flexibility in use and limitations that artificial ventilation therapy presents. Optimum ventilatory practice requires knowledge to ensure the choosing of the 'right' ventilator. It ensures informed practice and maintains optimum patient safety.

Negative-Pressure Ventilators
Negative-pressure ventilators create a vacuum around the chest or body to draw air into the lungs, simulating breathing. This method does not require an...

Ventilatory Modes
There are three ventilatory modes: full support, partial support, and spontaneous. These are described below.
Full Support Modes
Full support modes include controlled mechanical ventilation, continuous mandatory...
Physiological Control of Respiration
Breathing, a seemingly passive process, is regulated by the respiratory center in the brainstem. This center coordinates the involuntary control of respirations, which means it occurs without conscious effort, ensuring a smooth and uninterrupted pattern.
Regulation of Ventilation
The body maintains ventilation by monitoring levels of carbon dioxide (CO2), oxygen (O2), and hydrogen ion concentration (pH) in the arterial blood. Among these factors, the level of CO2 plays a crucial...
Factors Affecting Pulmonary Ventilation
Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...
