  2. Nasal cannula - Wikipedia

    en.wikipedia.org/wiki/Nasal_cannula

    A nasal cannula is generally used wherever small amounts of supplemental oxygen are required, without rigid control of respiration, such as in oxygen therapy. Most cannulae can only provide oxygen at low flow rates—up to 5 litres per minute (L/min)—delivering an oxygen concentration of 28–44%.

  3. Heated humidified high-flow therapy - Wikipedia

    en.wikipedia.org/wiki/Heated_humidified_high...

    The traditional low flow system used for medical gas delivery is the Nasal cannula which is limited to the delivery of 1–6 L/min of oxygen or up to 15 L/min in certain types. This is because even with quiet breathing, the inspiratory flow rate at the nares of an adult usually exceeds 30 L/min.

  4. Nasal administration - Wikipedia

    en.wikipedia.org/wiki/Nasal_administration

    Nasal administration, popularly known as snorting, is a route of administration in which drugs are insufflated through the nose. It can be a form of either topical administration or systemic administration , as the drugs thus locally delivered can go on to have either purely local or systemic effects ibuprofen or Tylenol for headaches along ...

    Cannula. A cannula ( / ˈkænjʊlə / ⓘ; Latin meaning 'little reed'; pl.: cannulae or cannulas) [1] is a tube that can be inserted into the body, often for the delivery or removal of fluid or for the gathering of samples. In simple terms, a cannula can surround the inner or outer surfaces of a trocar needle thus extending the effective ...

  6. Simple face mask - Wikipedia

    en.wikipedia.org/wiki/Simple_face_mask

    The simple face mask can deliver higher flow rates than nasal cannula (6–10 liters per minute) for an FiO2 of 30- 60% oxygen. Nasal cannula and simple face masks are described as low flow delivery systems. Unlike the non-rebreather and partial rebreather masks, the simple face mask lacks a reservoir bag.

  7. Non-rebreather mask - Wikipedia

    en.wikipedia.org/wiki/Non-rebreather_mask

    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.
