A spirometer is a gadget used to measure respiration flow rates. The device measures the volume of inspired and exhaled air from the lungs. It records both the quantity of air inhaled and exhaled and the rate at which that is done within a certain time frame. They are utilized in hospitals to enhance the working of lungs of patients particularly the incentive spirometer.
Some spirometers function on similar principles as gas meters. Normally, a soda cylinder is attached on the device to absorb carbon monoxide gas. Kymograph traces are generated for recording changes in the entire gas volumes. From these records, vital capacities, ventilation rates, breathing rates, and the tidal volumes may be calculated. General declines on the graphs can be used to calculate oxygen uptakes.
Basic forced volume vital capacity tests vary depending on the type of equipment used. During the operation, the patient is required to take the deepest breath possible and breath out into the detector as hard as they can thereafter. It is also demanded of them to exhale as long as possible preferably for least for six seconds. A nose clip can be used to prevent air escape through the nose while a filter mouthpiece prevents any possible spreading of disease causing microorganisms.
Spirometers play a fundamental role in the PFTs majorly abbreviated to pulmonary function tests. These tests form preliminary tests for health conditions of the lungs in patients. Lung conditions like asthma, bronchitis, and emphysema are diagnosed using these gadgets. Medical experts use spirometers for several applications, including analyzing the effects caused by contaminant materials on the activity of the lungs and establishing the existence of diseases.
Some tests performed using spirometers require both the efforts and the cooperation of the individuals under test. This is necessary to ensure correct results and that patients can perform the needed maneuvers that accompany the tests. The patients are also expected to adhere to necessary instructions, therefore due to this, some gadgets are not appropriate for use on individuals who are heavily sedated or unconscious. It is advisable to use other techniques for testing lung functionality of such people.
There are many types of spirometers such as incentive spirometers, fully electronic spirometers, body pneumotachometer and wind mill type spirometers. Pneumotachometer spirometers are used to measure the rates of flow of gases through detecting pressure changes across a fine mesh. It is advantageous as the investigated subject is free to inhale fresh air during the operation.
The benefit with some spirometers is their portability and presence of sensors which gauge the air speed. They are disposable hence preventing possible spreading of ailments. Additional electronic parts may assist the spirometers generate loops and volume curves. Absence of real time measurements and difficulty in calibration of results are the main disadvantages of spirometers. If the interior surfaces are kept unclean, bacteria may thrive there.
Getting a quality spirometer is not the biggest problem one can encounter. This results because there are many stores and shops that stock them. Online shops can be of assistance too in case there are no local stores. It is advisable to do some research before settling for any particular model.
