Spirometry is a clinical process through which lung functions are measured, specifically speed and volume of air inhaled and exhaled. It is among pulmonary function tests done on patients with lung problems and it also goes by the phrase measuring of breath. The pieces of equipment used to do the process are called spirometers. Buyers have a wide range of devices to choose from because there are many models in the market today.
The work of these devices is to establish abnormalities in aeration patterns and air motion out and into lungs. The gadgets establish 2 kinds of abnormalities in aeration patterns. The 2 abnormalities in aeration patterns are obstructive and restrictive. To achieve their tasks, various makes use different measurement techniques. Among those techniques are, use of pressure and/or ultrasonic transducers or water gauges.
These gadgets continue getting better as technology improves. At the present time several makes are in utilization in different around the globe. Among the key models are windmill-type, incentive, whole body plethymograph, pneumotachometer, peak flow type, fully electronic, and tilt compensated model. Of all the models body plethymograph has the highest accuracy with high precision in values taken. The great precision is partially because patients get enclosed in small spaces during the process.
The pneumotachometer gauges the flow rate of air by employing a fine mesh. The pressure of inhaled or exhaled gases is detected as they flow over the fine mesh, allowing measurement of their rate of flow. Patients are allowed to breathe in fresh air as the process continues. That is an advantage that lacks in most other models.
Fully electronic versions are an improvement of the other models because they lack fine meshes and/or moving parts. In these models, the rate of air flow is gauged using techniques such as ultrasonic transudcers and pressure difference. The accuracy is highly improved because there is no resistance or friction due to lack of moving parts. Hygiene is also high because of the disposable air flow channels built into them.
The most commonly used type is the incentive model. These models improve gaseous exchange in the lung of patient when used for a long time. In hospitals they are placed on benches or tables next to beds. Doctors instruct patients to breathe through them for a given number of times daily. Any improvements the patient makes in their breathing habits can be observed on the calibrations on the apparatus.
Windmill-type model can measure forced vital capacity without use of water. In comparison to the water-tank type, it is more portable and lighter. Measurements recorded are broad and range from 1000ml to 7000ml. When taking measurements, the apparatus must be maintained in horizontal position because it contains rotating discs. Tilt-compensated model contains 3D sensing mechanics, which allow backward or forward positions when in use.
The success of the testing is determined by cooperation given to the doctor by the patient. Normally values acquired from one test contain errors and are therefore not used as final results. Three repetitions must be done obtain final figures. Little children cannot understand directions cannot be tested because they cannot give correct figures.
