Technical Field
The invention relates to the technical field of nasal high-flow humidification oxygen therapy equipment, in particular to a respiration maintenance system for providing humidification oxygen therapy.
Background
HFNC is a treatment mode for continuously providing high-flow (8-80L/min) inhalation gas with controllable and relatively constant oxygen inhalation concentration (21-100%), temperature (31-37 ℃) and humidity for a patient through high-flow nasal obstruction. The treatment equipment mainly comprises an air-oxygen mixing device, a humidification treatment instrument, a high-flow nasal plug and a connecting respiratory pipeline.
