WebHow longer oxygen tubing can help. Where I work, the standard tubing length is seven feet. You attach the nasal cannula to a patient’s face. You plug the opposite end to a flowmeter on the wall. You turn the flowmeter up to 2-3 liters per minute (LPM). Most people with COPD only need a low flow of oxygen. So, 2-3 LPM works great for most ... WebThe oxygen concentrator had little flow reduction at 1 or 2 L and more flow loss at higher tubing lengths with 3, 4 and 5 L/min. Liquid oxygen was only mildly reduced at 125 ft (38.10 m) of tubing and 4 or 5 L of flow. Neither the concentrator nor liquid oxygen delivery units had flow reductions greater than 13.5 and 4.0%, respectively, at 2 L ...

WebAn atom of oxygen has a diameter of 7.4 x 10 –11 m. How do you calculate the diameter of an atom? The size of an atom is difficult to describe because atoms have no definite outer boundary. To overcome this problem, the size of an atom is estimated by describing its radius. In metals, this is done by measuring the distance between two nuclei ...
