To estimate the minimum total output flow needed to meet the patient’s inspiratory demands, do the following: Since we do not always actually measure VT for entrainment devices, you can determine it using the estimated VT formula. They are used onboard many ships to pump out flooded compartments: in the event of an accident, seawater is pumped to the eductor and forced through a jet, and any fluid at the inlet of the eductor is carried along to the outlet and up and out of the compartment. The Site offers products and services for sale. Description du produit « Tapis d'entraînement Airflow Zilco ».

This means that for every 1 liter set on the oxygen flowmeter, 0.6 liters of air is entrained. We won’t discuss the science behind this here, but it is worth noting that the amount of air that is entrained is very predictable primarily depending: The higher the oxygen flow, the more air is entrained; and the bigger the entrainment port openings, the more air is entrained; and the smaller the jet size, the more air is entrained. For example, if the patient’s minute volume is 8 L/min, the entrainment device should be set to deliver 3 – 4 times that amount (24 – 32 L/min) in total flow output. Fluid or Air Entrainment.
