Heated humidified high-flow therapy, often simply called high flow therapy, is a type of respiratory support that delivers a flow of medical gas to a patient of up to 60 liters per minute and 100% oxygen through a large bore or high flow nasal cannula. Primarily studied in neonates, it has also been found effective in some adults to treat ...
These requirements can be met through a number of devices dependent on situation, flow requirements, and personal preference. A nasal cannula (NC) is a thin tube with two small nozzles inserted into a person's nostrils. It can provide oxygen at low flow rates, 1–6 litres per minute (LPM), delivering an oxygen concentration of 24–40%. [68]
The simple face mask can deliver higher flow rates than nasal cannula (6–10 liters per minute) for an FiO2 of 30- 60% oxygen. [1] Nasal cannula and simple face masks are described as low flow delivery systems. [2] [3] Unlike the non-rebreather and partial rebreather masks, the simple face mask lacks a reservoir bag.
The nasal cannula (NC) is a device used to deliver supplemental oxygen or increased airflow to a patient or person in need of respiratory help. This device consists of a lightweight tube which on one end splits into two prongs which are placed in the nostrils curving toward the sinuses behind the nose, and from which a mixture of air and oxygen flows. [1]
In a continuous-flow system, oxygen is provided to the user continuously. It does not matter if the user is exhaling or inhaling as oxygen is flowing from the time the system is activated. Below the oxygen mask is a rebreather bag that collects oxygen during exhalation and as a result allows a higher flow rate during the inhalation cycle. [5]
The total flow of gas (oxygen plus the entrained air) will be greater than the patient's peak inspiratory flow so the delivered F I O 2 is independent of their respiratory pattern. [ 5 ] A controlled F I O 2 is particularly important for patients whose ventilation is dependent on hypoxic drive , [ 5 ] as may be seen in patients with chronic ...
A non-rebreather mask (NRB, non-rebreather, non-rebreather facemask, etc.) is a device used in medicine to assist in the delivery of oxygen therapy.A NRB requires that the patient can breathe unassisted, but unlike a low-flow nasal cannula, the NRB allows for the delivery of higher concentrations of oxygen.
Typically, these devices produce the equivalent of one to five liters per minute of continuous oxygen flow and they use some version of pulse flow or "demand flow" to deliver oxygen only when the patient is inhaling. [14] They can also provide pulses of oxygen either to provide higher intermittent flows or to reduce power consumption.
