Nasal high-flow therapy (nHFT) describes the supply of heated and humidified breathing gas via a nasal cannula. The gas flow administered is thus higher than the patient’s inspiratory respiratory flow. In neonatology, a flow of more than 1 LPM is considered to be high-flow therapy, while for adults, correspondingly higher values should be applied. (
Other names for nHFT: High-Flow Nasal Cannula (HFNC) or Heated Humidified High-Flow Nasal Cannula. All of them designate the same form of therapy.
nHFV combines the benefits of high‑frequency ventilation and non‑invasive CPAP support (
SNIPPV is the synchronized variant of NIPPV respiratory support. In NIPPV, the breaths are administered by the device independent of the patient’s own breathing. This can lead to conflicts in the synchronization between the patient and the device. In SNIPPV, the breaths are coordinated to the patient’s inspiration and conflicts are minimized.
