3. 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. An ideal non-rebreather mask does ...

   The amount of oxygen available to the patient in mouth-to-mouth is around 16%. If this is done through a pocket mask with an oxygen flow, this increases to 40% oxygen. If either a bag valve mask or a mechanical ventilator is used with an oxygen supply, this rises to 99% oxygen. The greater the oxygen concentration, the more efficient the ...

   Helmet used as a CPAP oxygen delivery interface. CPAP therapy uses machines specifically designed to deliver a flow of air at a constant pressure. CPAP machines possess a motor that pressurizes room temperature air and delivers it through a hose connected to a mask or tube worn by the patient.

7. Tracheal intubation - Wikipedia

   en.wikipedia.org/wiki/Tracheal_intubation

   Tracheal tubes can be used to ensure the adequate exchange of oxygen and carbon dioxide, to deliver oxygen in higher concentrations than found in air, or to administer other gases such as helium, [27] nitric oxide, [28] nitrous oxide, xenon, [29] or certain volatile anesthetic agents such as desflurane, isoflurane, or sevoflurane.
