Heated Humidified High-Flow Therapy
Heated Humidified High-Flow Therapy (pronunciation: /ˈhiːtɪd hjuːˈmɪdɪfaɪd ˈhaɪfloʊ ˈθɛrəpi/), also known as HHHFT or High-Flow Nasal Cannula (HFNC), is a type of respiratory support method that delivers a high flow of medical gas to a patient through an airway interface (nasal cannulae).
Etymology
The term "Heated Humidified High-Flow Therapy" is derived from the therapy's main characteristics. "Heated" refers to the warming of the gas, "Humidified" refers to the addition of moisture to the gas, and "High-Flow" refers to the high rate at which the gas is delivered to the patient.
Usage
HHHFT is used in various clinical settings, including intensive care units (ICUs), emergency departments, and general wards. It is used for patients with acute respiratory failure, chronic obstructive pulmonary disease (COPD), and congestive heart failure (CHF), among other conditions.
Mechanism of Action
The therapy works by delivering a high flow of heated and humidified gas, typically a mixture of oxygen and air, to a patient's airways. This helps to improve oxygenation, reduce work of breathing, and increase comfort.
