A non-rebreather mask is the instrument that is used to deliver oxygen in desaturated patients. The arterial oxygen saturation when goes below 90%. The oxygen flows from the reservoir which has a capacity of 8-15 liters. The patient can breath unassisted through this method. This method delivers the high concentration of oxygen.
According to the given situation, use of non-rebreather mask is ideal to reverse the manifestation of oxygen deficiency in the body.
Fraction of Inspired oxygen is the term that refers to the volumetric portion of oxygen in any inhaled gas as a result of inhalation.
A non-rebreather mask is the most effective in this case. This is due to it being able to deliver quantities of the fraction of inspired oxygen (FIO2) as high as 100 percent thereby reversing the manifestations observed.
The other modes in the options such as simple mask, face tent and nasal cannula can not deliver such quantity. They usually deliver lower levels of the Fraction of Inspired Oxygen(FIO2).
A theory is a carefully thought-out explanation for observations of the natural world that has been constructed using the scientific method, and which brings together many facts and hypotheses.
The kidneys remove urea from the blood through tiny filtering units called nephrons. Each nephron consists of a ball formed of small blood capillaries, called a glomerulus, and a small tube called a renal tubule.
