4 liters of oxygen per minute is within a normal range for oxygen therapy in adults. However, the appropriate oxygen flow rate should be determined by a healthcare provider based on the individual's specific needs and medical condition. It is important to follow the prescribed oxygen therapy plan to prevent any adverse effects.
On average, a person breathes in about 6-8 liters of oxygen per minute. This equates to approximately 360-480 liters of oxygen per hour.
Oxygen masks typically deliver a flow rate measured in liters per minute, with higher flow rates commonly used for patients needing higher concentrations of oxygen. At 15 liters per minute, the percentage of oxygen delivered by the mask will depend on the specific design and the individual's breathing pattern, but it can generally provide an oxygen concentration of around 60-90%.
On average, humans require about 2 liters of oxygen per minute at rest. This amount can increase during physical activity or in high-altitude environments to meet the body's higher demand for oxygen.
A C oxygen cylinder typically holds about 3400 liters of oxygen. At a flow rate of 2 liters per minute, it will last for approximately 28 hours.
An ambu bag can deliver oxygen at a flow rate of 6-15 liters per minute, depending on the patient's needs. The amount of oxygen delivered will depend on the duration of use and how effectively it is administered.
On average, a person breathes in about 6-8 liters of oxygen per minute. This equates to approximately 360-480 liters of oxygen per hour.
Convert 40% oxygen to liters
The normal amount of oxygen a person takes in is about 7 to 8 liters. This is for every minute.
Three liters per minute equates to 0.18kL per hour.
Take example that we r providing 2L/min of oxygen to a ptHuman lungs are 2 liters in volume by average. So...Average breath rate is 12 breaths per minute.In one minute the patient would take in 24 liters of air. You are supplying 2 liters of pure oxygen + 4.8 liters from air (20% of the 24 liters (Percent oxygen in dry air)) = 6.8 liters of Oxygen per minute.6.8 liters oxygen / 24 liters intake = 28.3% Oxygen

That's just me!
Convert oxygen litter/minute to percnt

Healthy lungs breathe between 6 (at rest) and 150 (during exercise) liters of air per minute.
To calculate the total oxygen exchanged while walking, first determine the total volume of air exchanged per minute by multiplying the breaths per minute (16) by the volume of air per breath (1.5 liters), resulting in 24 liters of air exchanged. Next, calculate the amount of oxygen in the inspired air: 20% of 24 liters equals 4.8 liters of oxygen inhaled. For the expired air, if it contained 1% oxygen, that would be 0.24 liters of oxygen expelled. Therefore, the net oxygen used during walking is 4.8 liters (inhaled) - 0.24 liters (exhaled) = 4.56 liters of oxygen utilized per minute.
