Options for ventilating the pediatric patient. Part 1. Mechanical properties of three generations of ventilators
Abstract:
The past 20 years have seen striking changes in ventilators for use in infants and children. Early in this period, we relied on traditional machines and techniques that were largely borrowed from adult medicine. The availability of second-generation machines brought better understanding of pulmonary physiology, particularly as it relates to oxygen transport. Today, third-generation ventilators very different from the others have forced abandonment of dogma concerning the manner in which molecules of gas enter and leave the lung. Their full impact cannot yet be judged, but they have shown great clinical promise and no doubt will change further our understanding of pulmonary physiology.

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...
Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...

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...
