Lung volumes and lung capacities refer to the volume of air in the lungs at different phases of the respiratory cycle.. The average total lung capacity of an adult human male is about 6 litres of air.. Tidal breathing is normal, resting breathing; the tidal volume is the volume of air that is inhaled or exhaled in only a single such breath.. The average human respiratory rate is 30– The HFNC overcomes flow limitations of low- and intermediate-flow devices by delivering up to 60 liters per minute of heated, humidified gas via nasal prongs ().An oxygen blender connected to the circuit enables precise titration of F i O 2 ranging from 21 to %, independent of flow. To ensure stable F i O 2 delivery to alveoli, device flow must meet or exceed the patient’s inspiratory.
Potassium (K +) is found in low concentration in the plasma and extracellular fluids ( to mEq/liter in a healthy adult). Normally about 80% to 90% of the potassium intake is excreted in the urine, the remainder in the stools and to a small extent, in the perspiration. About cups ( liters) of fluids a day for men About cups ( liters) of fluids a day for women These recommendations cover fluids from water, other beverages and food. About 20% of daily fluid intake usually comes from food and the rest from drinks.
For adults, the general recommendation from The U.S. National Academies of Sciences, Engineering, and Medicine is about: cups ( liters) a day for women cups ( liters) a day for men. – + ( x height in centimeters) + ( x weight in kilograms) = total body weight (TBW) in liters To get the percentage of water in your body, assume 1 liter equals 1 kilogram and then.
