Many may also be using new makes or models of ventilators they are unfamiliar with. Oxygen is an essential medicine required at all levels of the health care system; only high quality, medical-grade oxygen should be given to patients. A similar formula is used to determine oxygen consumption for walking speeds between 1.9 and 3.7 mph.1 At lower speeds, walking is generally a more efficient process than running. 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). Don't forget to do some warm-up and stretching before the runs.
