Original sentence: NO2) large quantities can be dissolved in body fluids rapidly.Nonetheless, this effect would only last a couple of minutes and  hypoxia can be avoided by increasing the fractional inspired oxygen concentration when recovering from NO2 anaesthesia.When a patient is recovering from NO2 anaesthesia, large quantities of this gas cross from the blood into the alveolus (down its concentration gradient) and so for a short period of time, the O2 and CO2 in the alveolus are diluted by this gas
