WebThe effective delivered oxygen concentration (which reaches the lungs) is usually 25–30%, if a patient is receiving 2–4 L/M of nasal O 2. In contrast, HFNO uses oxygen flows of 50–100 L/M. With this technique, the high flows delivered via the specially designed nasal cannulae now exceed the patient’s IFR. WebWith both CPAP and BiPAP the inspired oxygen (FiO2) can be titrated to achieve a target PaO2 or saturations. Close monitoring and serial blood gases are imperative for any patient being treated with non-invasive ventilation so any improvements or deteriorations in the clinical state can quickly be identified.
