The tympanometer measures the admittance or compliance of the tympanic membrane while different pressures are being applied to the external ear canal. The compliance of the TM is measured in cubic centimeters, and the pressure in the ear canal is measured in decapascals (daPa).The probe has different size plugs that provide a seal at the entrance to the external ear canal.hysics of the Tympanogram. If the middle ear space is filled with fluid, most of the sound is reflected back to the probe from the stiff tympanic membrane. If the middle ear space is filled with air, and the ossicles are intact, energy is absorbed by the tympanic membrane, ossicles, and inner ear structures.
Although they are a little bit higher in iron, mangoes, kiwi, star fruit, peaches, honeydew melon, pears, bananas, cantaloupe, lemons, watermelon, nectarines, blueberries, peaches, strawberries and pineapple are all relatively low in iron as well, containing less than 0.7 milligrams per serving.
Fortunately, many vegetables, such as broccoli and bok choy, which are high in iron, are also high in vitamin C so that the iron in these foods is very well absorbed. Commonly eaten combinations, such as beans and tomato sauce or stir-fried tofu and broccoli, also result in generous levels of iron absorption.on-heme iron, 60 percent of the iron in animal tissue and all the iron in plants (fruits, vegetables, grains, nuts) is less well absorbed. Because vegan diets only contain non-heme iron, vegans should be especially aware of foods that are high in iron and techniques that can promote iron absorption.
