Supplementary tests

In the consultation we carry out complementary tests indicated by your specialist in pulmonology to achieve a better diagnosis. We detail them below:


Pulse oximetry

Sat O2 + FC
Time: 1 minute

Non-invasive procedure, which determines the percentage of oxygen saturation of hemoglobin in the blood and the heart rate of a patient with the help of photoelectric methods. It consists of placing a clamp on a patient’s finger. Preferably without glaze.


Forced spirometry

Time: 10 minutes

Study of lung function, which measures respiratory volumes and flows, that is, the ability to accumulate air in the lungs and to move it. The test consists of asking the patient to perform a forced exhalation through a single-use mouthpiece with a bacterial filter.


Bronchodilation tests

Bronchodilator drug
Time: 15 minutes

Assessment of improvement in lung capacity. The test involves administering a bronchodilator drug through a chambered inhaler. In addition, a forced spirometry will be performed before and after.


Respiratory polygraphy

Snoring and sleep apnea
At home

It allows evaluating the presence of apneas, snoring and oxygen saturation during the night for the diagnosis of SAHS (sleep apnea and hypopnea syndrome). A nurse will give you instructions on how to put on the machine. It is done at the patient’s home. Includes follow-up visit and report.



Continuous positive pressure
At home

Once the presence of apneas or a high number of snoring is confirmed, a test is performed to assess the adaptation and efficacy of the CPAP treatment. A nurse will give you instructions on how to put on the machine. It is performed at the patient’s home or in consultation.



Thoracic ultrasound
Time: 20 minutes

Non-invasive, fast and painless test, in real time that is carried out in the same medical consultation. It is used to assess injuries or alterations such as (consolidation, pleural effusion, pulmonary edema and pneumothorax). Its main advantages lie in the absence of ionizing radiation on the patient.


Nitric oxide test

Time: 10 minutes

It is used to assess the degree of inflammation of the airways. The test consists of measuring the level of nitric oxide in exhaled air. The test consists of asking the patient to perform a sustained exhalation through a mouthpiece and must maintain the airflow within limits that appear on a digital screen.


Allergy tests

Prick test
Time: 20 minutes

Allergy skin test performed on the skin in order to identify the substance that can trigger an allergic reaction in the patient. It consists of applying a drop of pneumo-allergen to the skin of the forearm and puncturing the area in search of possible allergies.



Time: 10 minutes

A test that records the electrical activity of the heart that occurs with each beat. The patient is placed in the supine position and consists of applying electrodes to the heart area and clamps on the 4 extremities, to obtain the patient’s cardiac record.


Complete respiratory functional tests

Lung Volumes
Pulmonary diffusion and plethysmography
Time: 30 minutes

Test performed to determine the lung capacity and the degree of involvement of the patient’s disease. It measures the exchange of gases in the lungs and evaluates how oxygen passes from the lungs to the blood.


Bronchoprovocation tests

Time: 30 minutes

Test that aims to check if after performing physical exercise (running on a treadmill), the bronchial size decreases and assessing lung function before and after exercise. The patient should run at a fast pace for about 6-8 minutes from start to finish. A forced spirometry will be performed and the HR will be measured before and after.


Walking test

Time: 6 minutes

Test that allows measuring tolerance to effort and assessing whether there is any degree of limitation. It consists of measuring the maximum distance that a person travels on a flat surface in a time of 6 minutes. Blood pressure, heart rate, oxygen saturation will be taken before and after, as well as the degree of dyspnea on exertion.



CO CHeck

A test that determines the level of carbon monoxide ppmCO (carbon monoxide concentration per parts per million) in the air exhaled from the lungs. It allows easy-to-interpret results, which will allow us to work with smokers, obtaining great awareness.
