FiO2 stands for Fraction of Inspired Oxygen; it is a fraction of the amount of oxygen a patient is inhaling produced by an oxygen device such as a nasal cannula or mask. Different devices deliver different amounts of oxygen to the patient.
With a nasal cannula, it is assumed that the patient's oxygen intake increases 4 percent for every liter of oxygen that flows through the cannula.
Using a Venturi mask, which mixes air from the room with the oxygen, provides an accurate and constant FiO2 unlike the nasal cannula. It is often used when doctors are worried about carbon dioxide retention.
The reaction for Na2CO3, sodium carbonate, and HCl, hydrochloric acid, is 2HCl + Na2CO3 -> 2NaCl + CO2 + H2O. Two moles of hydrochloric acid and one mole of sodium carbonate form two moles of salt, one mole of carbon dioxide and one mole of water in an irreversible reaction.Full Answer >
