What is the maximum amount of oxygen a home can hold?
The standard adult nasal cannula can run as little as 12 liter per minute.The rule of thumb is to deliver 24% of oxygen at one liter, with an increase of 4% for each additional liter flow.
How many liters of oxygen should a COPD patient be given?For patients with a history of COPD, aim for oxygen saturation 88-92% and give oxygen at no more than 28% via venturi mask or 2 L/minute.
There is a summary of Oxygen Concentrator liter flows.An oxygen flow rate of 2 LPM means the patient will get 2 liters of oxygen into their nostrils in 1 minute.70% of patients are prescribed less than 2 liters of oxygen per minute.
At 6 LPM, the approximate FiO2 is less than 50%.A 4% increase in FiO2 is achieved by every 1 LPM increase.When approximating your effective FiO2 at home, you can use this easy rule of thumb.
