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.Know More
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.
According to WebMD, "PCA" stands for patient controlled analgesic. With this type of pain control, the patient is able to increase or lower the medication as they need it. Sometimes, the pump gives out a small, steady flow of pain medication that allows a patiend to add more if needed.Full Answer >
SpO2 is the saturation of oxygen in the blood as measured by a pulse oximeter. A pulse oximeter is non-invasive and measures the SpO2 through the capillary bed, often at a fingertip. This is different from SaO2, which measures the oxygen saturation of arterial blood and requires blood sampling.Full Answer >
