What is a knitsmograph?
Pondhysmograph is a piece of medical equipment used to measure the volume of different parts of the body. It is most often used to measure the volume of a specific organ or limbs, but can also measure the body as a whole. In general, the body or organ changes due to a change in the amount of blood or air in the content. There are several different types of knitmographs, including types for lung, airways and penis. Everyone is used to measure the volume of a different part of the body to help with problems such as air passage, poor blood circulation and sexual excitement problems in men. This requires in most cases a closed chamber and mouthpiece, although modern machines sometimes do not need a closed area. The person undergoing the test must then be inhaled from exhaling, while the pressure inside the box is measured. Through the box is closed from the outside world, any change in the box pressure reflects in the lung change. Using this information, the lung volume can be calculated using formulas that relate to pressure and volume.
In some cases, the absolute lung volume may not be important, but the difference between the volume of empty and full volume is. For this reason, the pulmonary knitmograph can measure residual lung capacity and overall capacity to compare two. Diseases that cause an obstacle can be explored using this technique.
The air mograph is used to estimate the volume of a particular area of the body. For example, the leg can be closed in a chamber that allows you to detect and measure any volume change. Water knitmographs are similar, but are generally more accurate than air versions. In many cases, however, air is used for comfort despite the fact that it does not produce such reliable results.
Penile knitsmographs are also commonly used to detect volume changes - and thus blood flow - into the penis. Although the same techniques cannot be used in women, there is a vaginal method called photoplethysmography that can be usedt to measure blood flow in the area. Some scientists have tried to use the results of these tastes to prove sexual orientation or various levels of excitement - but penile attachment is not considered legal evidence.
