HFNC Machine Makes Breathing More Free

In 2014, the HFNC machine began to be used in China, and it has been rapidly popularized in clinical practice within a few years, and its clinical efficacy has been widely recognized by doctors in the top three hospitals. It also played an important role in COVID-19. However, the general public does not know much about the HFNC machine, so it has not been widely popularized in secondary hospitals, community hospitals, rehabilitation hospitals and nursing homes.

Ⅰ. What is HFNC machine?

The HFNC machine refers to a high-flow nasal congestion that continuously provides patients with a treatment equipment with relatively constant and controlled oxygen concentration (21%-100%), temperature (31-37 ℃) and high humidity (8 -80 L/min). The equipment mainly includes an air-oxygen mixing device, a humidification treatment instrument, a high-flow nasal obstruction and connecting breathing tubes.

Ⅱ. Who is suitable to use the HFNC machine?

The HFNC machine can be used for the early application of chronic obstructive airway disease, bronchiectasis, pulmonary cystic fibrosis, mild to moderate acute respiratory distress syndrome, pneumonia, pulmonary fibrosis, light and moderate OSASH in patients with cardiogenic pulmonary edema and hypoxia after surgery. As long as the following conditions are met:

1. Mild to moderate type I respiratory failure (100 mmHg≤PaO2/FiO2<300 mmHg)

2. Mild respiratory distress (respiratory rate> 24 breaths/min)

3. Mild ventilatory dysfunction (pH≥7.3)

4. Those who are intolerant or have contraindications to traditional oxygen therapy or non-invasive positive pressure ventilation

Whether it is in the progression or in the prognosis stage of the disease, matching respiratory support methods are required, from nasal low-flow oxygen therapy in mild cases to high-concentration mask oxygen therapy, non-invasive ventilation, and invasive ventilation. After improvement, gradually reduce respiratory support. In this cycle, patients with high-concentration mask oxygen and non-invasive ventilation can use the HFNC machine and obtain good therapeutic effects.
