Oxygen output in pulse dose settings is not directly comparable to continuous liter flow. Put your result time into the calculator and read out your VO2 max value. Your VO2 at this stage of maximal exertion is called your maximal oxygen consumption ( VO2max ). Our initial runs to assess E cylinder oxygen consumption of various types of ventilators demonstrate that fluidic and turbine style ventilators consume more oxygen than compressor style ventilators. Welcome to Version 9.0 of the VAE Calculator. This parameter describes the amount of oxygen the individual's body can utilize in one minute. >> This practice question was taken from our TMC Test Bank. Ventilation rate is expressed as the volume of gas entering or leaving the lungs in a given amount of time. Firstly, you should find an appropriate location to walk precisely 1 mile (1609 meters).

ALternatively, you could just hook an ambubag up to the ETT and then use your flowmeter and pressure gauges to estimate. JavaScript is disabled. sex = male, age = 32 years, weight = 78 kg. This test is based on stepping up 16.25 inches (0.41 m) from ground level. However, the results should be pretty similar, without a big difference. endobj 25.7 mL/cm H2OD. Calculate the volume of the released gas (Vg) by multiplying the volume of the liquid nitrogen (in liters) or weight of solid carbon dioxide (in Kg) by the expansion ratio of LN (.682) or the inverse density of CO2 (.552 m3/Kg). The term VO2 max means the same as maximal aerobic capacity, maximal oxygen uptake or maximal oxygen consumption. The turbine ventilator tested uses a continuous flow of 10 l/min, which is gas inefficient. The LTV 1200 Series ventilator, is able to accommodate adult to pediatric patients, and is ideal for patient transport particularly ER or emergency services. If your body isn't used to that kind of sports activity, a few practice runs before the test day might be essential.
