Final answer:
The Nasal Cannula delivers oxygen to a patient. The volume rate is measured in LPM and the FiO2 percentage indicates the concentration of oxygen.
Step-by-step explanation:
The Nasal Cannula delivers oxygen to a patient through two small prongs that fit into the nostrils. The volume rate of oxygen delivered by the Nasal Cannula is measured in liters per minute (LPM). The usual flow rate is between 1-6 LPM, depending on the patient's needs and condition.
The FiO2 (Fraction of Inspired Oxygen) percentage indicates the concentration of oxygen delivered by the Nasal Cannula. The usual FiO2 range for a Nasal Cannula is between 24% and 44%. Higher FiO2 can be achieved by using other oxygen delivery devices such as a mask or ventilator.
The abbreviation FiO2 stands for Fraction of Inspired Oxygen, which represents the amount or fraction of oxygen in the air that a person is inhaling.
