1 The COSMED metabolic cart uses a two point calibration process to calibrate the O and CO analyzer a What are the two points for O and for CO 0 16 and 20 93 CO 5 and 0 04 b What does each reference point represent The amounts that are fractionally inspired are represented by the percentages of O and CO in the atmosphere which are 20 93 and 0 04 respectively The percentages of calibrated gas that is similar to the fraction of Oz and Co in exhaled air is 16 and 5 respectively 2 What did we connect to the back of the cart Sampling line and Turbine line 3 What does the turbine do And how is it calibrated The turbine is used to measure the air flow which is defined as the amount or air moved per unit time usually per minute The 3 liter syringe is used to calibrate the turbine 4 What is the volume of the calibration syringe 3 liter syringe 5 Why should we perform a calibration
