Abstract:
Differences between assist-control pressure and volume ventilation are minimal provided that peak inspiratory flow delivered at early inspiration matches patient demand Ventilation at constant flow and controlled tidal volume allow instantaneous analysis of the patient-ventilator interactions and the mechanical properties of the respiratory system. The cycle-per-cycle variability of peak inspiratory flow, which is permitted in pressure-limited modes, may allow better patient comfort. We do not know if one mode (pressure controlled or volume controlled) is superior to the other in terms of outcomes.

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...

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...

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,...
