→Physical Characteristics of an Oxygen Bleed
1-PSI is 70 cm-H2O, so the oxygen concentrator flow is fully delivered to the CPAP circuit.
A typical oxygen bleed circuit delivers between 1-liter/minute (L/min) to 3-L/min.
The typical CPAP or Bilevel respiratory circuit flows 40 30 to 80 L/min of air volume in the absence of large leaks. (our example will assume 60 30 L/min)
=What is the oxygen concentration in the diluted CPAP circuit?=
