Use of an Integrated Low-Flow Anesthetic Vaporizer, Ventilator, and Physiological Monitoring System for Rodents

Abstract:
We developed a new pressure-limited ventilator system by modifying the Bird #7001M ventilator. Our aims were to free ICU floor space by wall-mounting the ventilator, and to employ a pressure-limited, gas-powered ventilator similar to our transport ventilator to aid in the training of members of our transport team. The system provides a peak pressure of 150 cm H2O and a peak flow of 208 L/min. When coupled with heated pneumatic nebulizers, it quietly provides a maximum gas flow of 208 L/min with nebulized water at 37 degrees C. We successfully used this system for over 4 years to provide a wide range of ventilatory support and oxygen therapy.

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,...
