There are many sources of error inherent in testing a patient's DLCO, including variation in breath holding time, low inspiratory capacity and variable inspiratory flow rates, insufficient time between maneuvers, improper hemoglobin and carboxyhomoglobin corrections, choosing inappropriate equations or nomagrams for predicted values, patients cardiac output status, predicted equations and calculations, altitude considerations, test gas quality and tank pressure, demand valve resistance, gas analyzer accuracy, valve integrity and function, among others, [ILLUSTRATION OMITTED] There are many other factors that influence DLCO.

A first breath activated positive pressure demand valve provides low breathing resistance and excellent dynamic performance a" particularly at high flow rates.
The test begins with the patient exhaling to RV, and then inspiring to TLC of 100% oxygen from a reservoir or demand valve.
5 to 25L/Min and can be used to supply demand valves or portable ventilators up to 100L/Min.
The turbine flow delivery was smooth and the demand valve accommodating, allowing flow rates up to 180 LPM for spontaneous breaths and there was no noticeable difference in flow delivery when a high pressure source gas was not used.
