Low Flow Oxygen Mask

Summary. Both high-flow and low-flow oxygen delivery systems are capable of administering a wide range of FiO 2.However, the terms high and low do not reflect the delivered FiO 2 in fact, it refers to the flow of gas delivered to the system. Low-flow systems are used in more critically stable patients they deliver oxygen at flow rates below the patient's respiratory requirements.

ltpgtNon-rebreather mask is considered a low-flow oxygen delivery system. It provides a high concentration of oxygen but does not ensure a precise oxygen concentration due to varying patient ventilation.ltpgt A nurse is assessing a patient who has been using a nasal cannula for oxygen therapy. The patient complains of nasal dryness and irritation.

Note In most low flow systems, the flow is usually titrated on the oxygen flow meter and recorded in litres per minute LPM. Where the Airvo2 is used as an oxygen delivery device the flow from this device is independent to the flow of oxygen - both should be clearly documented. High flow delivery method High flow systems include

The table in the advanced use slider at the top left view of this article shows flow set on the Venturi Air entrainment mask - the total flow O2 flow air entrained and the FIO2. This helps demonstrate why at low FIO2 - the Venturi mask provides a far more consistent FIO2 than nasal cannula or simple facemask.

Also, there is a tendency to confuse flow systems with oxygen concentrations. However, both are mutually exclusive in that a high-flow system, viz. Venturi mask, can deliver FiO 2 as low as 0.24, whereas a low-flow system like a nonrebreather mask can deliver FiO 2 as high as 0.8. Thus, if the ventilatory demand of the patient is met completely by the system, then it is a high-flow system.

Adult and paediatric medium oxygen masks offer variable oxygen concentration for use in respiratory, emergency and post-operative care. Intersurgical - Oxygen masks - variable oxygen concentration low flow

The ONLY mask that can supply oxygen at low flow. This mask works great for patients that use oxygen concentrators. Flow Rate - 1 liter per min. - 40 liter per min. FiO2 - 24 to 90 This unique product can be used to replace Nasal Cannulas, Simple Masks, Partial Rebreathing Masks, and Non-rebreathing Masks.

Simple Oxygen Mask. Description A basic mask that covers the nose and mouth, allowing oxygen to flow through small holes on the sides to prevent carbon dioxide buildup. Flow Rate. 5 to 10 Lmin FiO Fraction of Inspired Oxygen Approximately 40 to 60 Flow rates below 5 Lmin are discouraged to avoid CO rebreathing.

Exhaled CO2 escapes through openings, helping reduce low flow CO2 rebreathing risk and related sentinel events. An attached flow rate tag supports correct use. Evaluation of safety and cost of an open-design oxygen mask in a large community hospital. Respiratory Care.2018634412-416.
