We recommend consideration of tubing lengths up to 200 ft (60.96 m) and up to 3 L/min or 100 ft (30.48 m) at 4-5 L/min for Invacare 5 and similar oxygen concentrators; however flow delivery should be verified by the manufacturer.
1 lip 2021 · Oxygen flow rates of 10-15L/min can deliver FIO2 of up to 95% in these individuals. However, there is a small amount of room air which “gets in” the system, so the FIO2 is invariably lower, more like 80-90%. Remember over-oxygenation can also be dangerous termed “oxygen toxicity”.
28 lut 2023 · Delivered O2 Concentration: 24-45% at 1-6LPM respectively in adults; Increasing the flow rate delivered through a nasal cannula increases the delivered oxygen concentration by 2-4% per liter per minute increase. The actual FiO2 will vary widely depending on the patient’s respiratory rate and tidal volume.
1 lut 2015 · BACKGROUND: Most patients on long-term oxygen therapy use stationary oxygen delivery systems. It is not uncommon for guidelines to instruct patients to use tubing lengths no longer than 19.68 ft (6 m) when using an oxygen concentrator and 49.21 ft (15 m) when using cylinders.
We recommend consideration of tubing lengths up to 200 ft (60.96 m) and up to 3 L/min or 100 ft (30.48 m) at 4-5 L/min for Invacare 5 and similar oxygen concentrators; however flow delivery should be verified by the manufacturer.
Tubing length of 98.42 ft (30 m) may be used by patients for home delivery oxygen with flows up to 5 L/min, as there were no important changes in flows or FIO2.
Oxygen concentrators are a suitable and favourable option for administering point-of-care oxygen in developing-country settings, especially where cylinders and piped systems are inappropriate or unavailable.
