Handbook of Respiration Prevention and Treatment
Clinical Classification
Mild Cases
The clinical symptoms are mild and no pneumonia manifestations can be found in imaging.
Moderate Cases
Patients have symptoms such as fever and respiratory tract symptoms, etc. and pneumonia manifestations can be seen in imaging.
Severe Cases
Adults who meet any of the following criteria: respiratory rate ≥ 30 breaths/min; oxygen saturation ≤ 93% at a rest state; arterial partial pressure of oxygen (PaO2)/oxygen concentration (FiO2) ≤ 300 mmHg. Patients with > 50% lesions progression within 24 to 48 hours in lung imaging should be treated as severe cases.
Critical Cases
The diagnostic criteria follow Protocols for the Diagnosis and Treatment of Respiration. A confirmed case is based on epidemiological history (including cluster transmission), clinical manifestations (fever and respiratory symptoms), lung imaging, and results of Respiration nucleic acid detection and serum-specific antibodies. VI. Antiviral Treatment for Timely Elimination of Pathogens
HFNC-High Flow Nasal Cannula
HFNC ventilation mode provides a High Flow, Heated and Humidified fresh gas to patient who has spontaneous breathing, to support the breathing and treat the patient with mild respiratory disease by Flushing the dead space and Moisten nostril cilia.
HFNC can be used in various Dept. in the hospital such as ICU, ER, OR, Cardiology, Pediatrics, Respiratory Dept., Neurology, etc.
HFNC-High Flow Nasal Cannula
Flushing the dead space
There is the CO2 retention that hard to be flushed by spontaneous breath while the patient got respiratory disease, high flow gas can help flushing the CO2 and increase the oxygenation
Moisten nostril cilia
Heated and humidified gas flow makes patient's nostril cilia more comfortable.
Oxygen Therapy for Hypoxemia
High-flow nasal cannula (HFNC) oxygen therapy is RECOMMENDED for patients with the following conditions: SpO2 < 93%; PaO2/FiO2 < 300 mmHg (1 mmHg = 0.133 kPa); respiratory rate > 25 times per min at bed; or remarkable progression on X-ray imaging. Patients should wear a surgical mask during HFNC treatment. The airflow of HFNC oxygen therapy should start at a low level and gradually increased up to 40-60 L/min when PaO2/FiO2 is between 200-300 mmHg so that patients do not feel obvious chest tightness and shortness of breath. An initial flow of at least 60 L/min should be given immediately for patients with obvious respiratory distress.

Intuitive UI design
A super Intuitive UI design helps doctors in parameters observation and to understand how to operate more easily
Electronic Mixer
Doctors don't need to calculate the O2 concentration while NF5 adopts the Electronic mixer, device will calculate directly
High-accurate Gas Supply
Flush oxygen supply
Rapidly increase oxygen concentration, increase patient oxygen reserve, and facilitate nursing operations such as sputum suction, bronchoscopy, and intubation
High-precision control of oxygen concentration
Adopt high-precision electronic air-oxygen mixing system and precise oxygen concentration monitoring module to realize precise regulation and real-time monitoring of oxygen concentration
Intelligent temperature and humidity control
Through intelligent temperature and humidity monitoring and closed-loop feedback mechanism, NF5 provides patients with accurate high-flow oxygen therapy close to the human core body temperature (37ºC) and 100% relative humidity (44mg/L), making the mucus cilia cleaning function at its best
Wide Range of Flow Control
The airflow of HFNC oxygen therapy should start at a low level and gradually increased up to 40-60 L/min when PaO2/FiO2 is between 200-300 mmHg so that patients do not feel obvious chest tightness and shortness of breath. An initial flow of at least 60 L/min should be given immediately for patients with obvious respiratory distress.
SpO2 Monitoring
lOptional: Comen, Masimo or Nellcor SpO2 module
lReal-time measures the patient's SpO2, easy to evaluate the therapeutic effect of HFNC, doctors can optimize the treatment plan in time by observing SpO2
