Study Of Lung Capacity Of An Individual By Using Spirometer

2878 words - 12 pages

Title : Study of lung capacity of an individual by using spirometerIntroduction :RespirationThe primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. When we breathe, we inhale oxygen and exhale carbon dioxide. This exchange of gases is the respiratory system's means of getting oxygen to the blood.Respiration is achieved through the mouth, nose, trachea, lungs, and diaphragm. Oxygen enters the respiratory system through the mouth and the nose. The oxygen then passes through the larynx (where speech sounds are produced) and the trachea which is a tube ...view middle of the document...

There are several versions of this laboratory apparatus available with most of all consist of a chamber (of capacity approximately 6 dm3) suspended freely over water and counterbalanced so that gas passed in or drawn out makes the chamber rise or fall. You can make a permanent record of the movements of the chamber either by attaching a pen to it and allowing it to write on a drum revolving slowly (kymograph) or by attaching a motion sensor which will convert movement into electronic signals that are then interpreted by your data logging software.This typical type of spirometer consists of a Perspex lid enclosing the spirometer chamber, hinged over a tank of water. This chamber is connected to the person taking part in the experiment via an interchangeable mouthpiece and flexible tubing. As breathing proceeds, the lid rises and falls as the chamber volume changes. With the spirometer chamber filled with air, the capacity of the lungs when breathing at different rates can be investigated. Incidentally, if the spirometer chamber is filled with oxygen, and a carbon dioxide-absorbing chemical such as soda lime is added to a compartment on the air return circuit, this apparatus can be used to measure oxygen consumption by the body as well.Nevertheless, due to the fact that the aforementioned spirometer is too bulky that it is hardly possible to be carried around efficiently, there are some hand-held versions of spirometers available - small devices that measure air flow and calculate volume electronically. For instance, there is a newly-introduced product, spiropet spirometer which is going to be used in this experiment. In addition, Philip Harris offers a 'pocket spirometer' which can be used outside the laboratory for collecting data in the field, and PASCO produce a data-logging spirometer (Pasport Spirometer) for which you would need the Data Studio software, but it produces instant traces on screen.Spiropet spirometer is a completely new product. It can measure vital capacity (forced vital capacity, forced lung capacity), without using water. It has a number of advantages over conventional tank-type spirometer, which make it easier to handle: handiness (lightweight and small size). It has a broad measurement range of 1000 ml- 7000 ml. Exhale through the device to measure vital capacity. Spiropet spirometer gives a very accurate measurement of lung volume (forced lung volume). Spiropet spirometer includes 50 disposable plastic mouthpieces. It can be used for many purposes, including sports tests and health care.Vital Capacity (VC )Vital capacity is the maximum amount of air a person can expel from the lungs after a maximum inspiration. It is equal to the inspiratory reserve volume plus the tidal volume plus the expiratory reserve volume.A person's vital capacity can be measured by a spirometer which can be a wet or regular spirometer. In combination with other physiologicalmeasurements, the vital capacity can help make a diagnosis of underlying...
