Book excerpt: INTRODUCTION: Commercial lightweight surface Supply divers' consoles underwent unmanned resistive effort testing. This report presents results from the Dive Lab XLDS RDC-3 and Interspiro DP2 lightweight consoles. METHODS: Four Dive Lab XLDS RDC-3 and five Interspiro DP2 consoles were tested. Resistive effort wee determined at a water temperature of 38 F (3.3 C). A breathing simulator with a sine wave breathing pattern was used, and the exhaled air was heated and humidified. Testing was done at depths from the surface to 198 feet of seawater (fsw; 60.7 meters of seawater [msw]) in steps of 33 fsw (10.1 msw) and at ventilations ranging from 22.5 L/min to 90 L/min. RESULTS: The Dive Lab XLDS RDC-3 console met the NEDU resistive effort performance goal of 1.75 kPa at a respiratory minute volume (RMV) of 62.5 L/min to 132 fsw with the MK 20 (nonpositive pressure) full face mask and to 165 fsw with the MK 21 helmet. The Interspiro DP2 console met this same performance goal to 198 fsw with the Divator MKII (positive pressure) full face mask.
