Like the face mask, the nasal cannula can be an inefficient means of oxygen delivery because of flow limitations, particularly in patients with a high inspiratory flow or high minute ventilation.

Since higher rates of flow can be more drying, using certain cannulas, masks, or humidifiers can help make you more comfortable.

Non-rebreather masks are used to deliver high concentrations of oxygen in emergency situations. They may be used for traumatic injuries, after smoke inhalation, and in cases of carbon monoxide ...

The non-rebreathing mask (sometimes called a Hudson mask) with an oxygen reservoir bag (Fig 1) can be used to deliver high concentrations of oxygen to a spontaneously breathing patient.A one-way valve ...

Material types include plastic, silicone, rubber, disposable, and re-usable venturi masks. Oxygen flow rates range from low 1-6 L/min to high 12-15 L/min and include variable flow rates.

The rate of reintubation at 72 hours and 28 days was not different among patients with hypoxemia after extubation who received VenturiMask oxygen compared with high-flow nasal oxygen.The ...

A passenger oxygen system is a continuous flow system. When activated, the chemical generator produces oxygen for the designed time at a continuous rate; the bag allows for expansion and ...

The flight deck's oxygen masks are made to sustain prolonged operations with a higher flow rate of oxygen.

Flow rates were determined by flow gauges (pressure-reduction type) connected in a line between the oxygen source and the humidifying device.
