Abstract:
Patients with respiratory failure and poor pulmonary compliance requiring high levels of positive pressure ventilation are at high risk during intrahospital transportation. Most ICU ventilators currently do not have a built-in power supply. Manual bag-valve ventilation frequently is used but often without optimum mean airway pressures or minute ventilation guarantees. Transport ventilators also are limited in their ability to provide high positive end-expiratory pressure, variable inspiratory-expiratory ratios, or pressure-controlled ventilation. The 3M SARNS HELP (Hospital Emergency Limited Power) 115, a portable battery, provides continuous power to ICU ventilators and eliminates ventilator circuit interruption for the critical period of patient transportation.

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,...
