Spirometry
It is a test that determines the Lung Capacity. It is done through the use of a spirometer, which is a device that records the amount of air that a person (according to Age, Size and Sex) inhales and exhales, as well as the speed at which said air is displaced out or in.
In the workplace, spirometry allows determining the respiratory limitations of a worker to certain exposures that could cause injuries or decreased lung capacity in a given period of exposure, under a specific risk.
In relation to the personal history of the patients who perform the test, these are important since Smoking, Cooking with Wood, Allergies are some of the non-occupational exposures related to the alteration of the results.
There are occupational risks that alter the test, such as exposures to: Smoke, Gases, Vapors, Particles, Mists and other residuals that can be inhaled or breathable, these generate changes in the spirometric curve characteristic according to the ATS standards (American Thoracic Society ) and ERS (European Respiratory Society).
This information is necessary to take preventive and respiratory protection measures depending on the position, the risk factor and the source of exposure to which each of the workers could be found.

Visual acuity
It is a test used to assess the worker's visual capacity, which includes: Assessment of near and far visual acuity, color perception, depth perception and muscle balance, allowing the severity of optical defects to be classified and identifying those who require additional tests. sooner.
Prior to the test, it is always recommended to carry out a check-up with the ophthalmoscope. This is because there may be structural elements in the eyeball that affect the performance of the test.
Visual acuity alone does not generate enough information on eye conditions, so the situation of this important organ is also assessed in the physical check-up. With the above, the quality standards in the visual check are met.
Electrocardiogram
It is a test that records the electrical activity of the heart that occurs in a rhythmic manner. This transmission is collected from the patient's body surface and printed on paper using a graphical representation or plot. It is here where different waves are observed that represent the electrical stimuli that will be translated by the doctor and determine the patient's cardiological condition.
It is used to measure the rhythm and regularity of heartbeats, the size and position of the atria and ventricles, any damage to the heart, and the effects that certain drugs or devices implanted in the heart (such as pacemakers) may have on the heart.
The Electrocardiogram is also very useful in acute episodes of coronary disease, such as myocardial infarction. Arrhythmias are often misdiagnosed and thus the assessment with the Electrocardiogram generates vital information on the patient's health status.
Audiometry
It is a test to specify hearing capacity through stimulation using pure sounds (Tones) of different intensity levels at different frequencies (Hz) generated by the audiometer. This instrument allows to determine the quality of the patient's Hearing.
The technique can be applied to the entire population in general (Adults and Children), but in this particular case to those exposed to Noise (According to Standard 618, Greater than or equal to 85 dB is considered Noise), as a tool for early detection of cases of hearing damage, ideally when they are still asymptomatic, as well as to evaluate the effectiveness of the management carried out in the Epidemiological Surveillance Systems or Programs to control said risk factor in work environments.
It is important to mention that chronic diseases affect the quality of hearing, such as Diabetes and Arterial Hypertension, these elements are appreciated prior to the test and provide a large amount of information about the hearing quality of the person evaluated.
It is a test of great diagnostic value and is decisive in decision-making both for the worker and for the work area according to Hygiene and Safety standards.
