“…El CPET es un examen no invasivo, ambulatorio y breve (< 20 min) 4 . Durante la prueba, el sujeto se somete a un esfuerzo incremental de carácter máximo 1,2 , permitiendo evaluar paralelamente parámetros oxihemodinámicos como frecuencia cardiaca (fc), electrocardiograma de 12 derivaciones, presión arterial (PA), oximetría de pulso para medición de saturación (SatO 2 ) y gases espirados, a través de mascarilla hermética 3 (Tabla 1, Figura 1).…”

“…Sin embargo, todas son evaluaciones en reposo que no dan cuenta certeramente de la intolerancia al esfuerzo 1 . Otras pruebas que sí son de esfuerzo, tales como el test de caminata de 6 min (TC6m), el test de escalera, el test incremental de la lanzadera ("shuttle test") son evaluaciones submáximas o máximas, pero que no logran precisar el origen de la disnea, ni dan información completa sobre el estado funcional de los diferentes sistemas relacionados con este síntoma 2 .…”

Cardiopulmonary exercise test for diagnostic and prognostic purposesThe functional assessment of patients with dyspnea usually uses static or submaximal exercise tests, which provide limited information because they do not expose patients to the real situation that causes exercise intolerance. The cardiopulmonary exercise test (CPET) is an increasingly used tool that can be used in these circumstances. It determines peak oxygen consumption, anaerobic threshold and cardiac and respiratory reserves, measuring oxygen uptake and carbon dioxide production during standardized exercise conditions. It is useful for risk assessment in cardiothoracic surgery and can provide valuable information such as the timing for transplant in patients with severe chronic disease. The test is non-invasive, has a short duration, and exhibits an adequate safety profile in specialized centers. It is mainly indicated for the dynamic evaluation of athletes or patients with heart, respiratory, and neuromuscular diseases, it is essential part of the study of dyspnea of unknown origin, and in the prognostic assessment of patients who face highly complex interventions. This review provides a comprehensive review of CPET with emphasis on its main indications in healthy people, athletes and, in particular, in functional evaluation of patients with exercise limitations in the context of their chronic diseases.

The concept of detection of dynamic lung hyperinflation using cardiopulmonary exercise testing

et al. 2023

Dynamic lung hyperinflation (DLH) caused by air trapping, which increases residual air volume, is a common cause of shortness of breath on exertion in chronic obstructive pulmonary disease (COPD). DLH is commonly evaluated by measuring the decrease in maximal inspiratory volume during exercise, or using the hyperventilation method. However, only few facilities perform these methods, and testing opportunities are limited. Therefore, we investigated the possibility of visually and qualitatively detecting DLH using data from a cardiopulmonary exercise test (CPET). Four men who underwent symptom-limiting CPET were included in this study, including a male patient in his 60s with confirmed COPD, a 50s male long-term smoker, and 2 healthy men in their 20s and 70s, respectively. We calculated the difference between the inspiratory tidal volume (TV I) and expiratory tidal volume (TV E) per breath (TV E-I) from the breath-by-breath data of each CPET and plotted it against the time axis. No decrease in TV E-I was observed in either of the healthy men. However, in the patient with COPD and long-term smoker, TV E-I began to decrease immediately after the initiation of exercise. These results indicate that DLH can be visually detected using CPET data. However, this study was a validation of a limited number of cases, and a comparison with existing evaluation methods and verification of disease specificity are required.

Background Dynamic lung hyperinflation (DLH) caused by air trapping, which increases residual air volume, is a common cause of shortness of breath on exertion in chronic obstructive pulmonary disease (COPD). DLH is commonly evaluated by measuring the decrease in maximal inspiratory volume during exercise, or using the hyperventilation method. However, only a few facilities perform these methods, and testing opportunities are limited. Therefore, we investigated the possibility of visually and qualitatively detecting DLH using data from a cardiopulmonary exercise test (CPET). Methods Four men who underwent symptom-limiting CPET were included in this study, including a male patient in his 60s with confirmed COPD, a 50s male long-term smoker, and two healthy males in their 20s and 70s, respectively. We calculated the difference between the inspiratory tidal volume (TV I) and expiratory tidal volume (TV E) per breath (TV E-I) from the breath-by-breath data of each CPET and plotted it against the time axis. Results No decrease in TV E-I was observed in either of the healthy males. However, in the patient with COPD and long-term smoker, TV E-I began to decrease soon after the start of exercise. Conclusion These results indicate that DLH can be visually detected using CPET data. However, this study was a validation of a very limited number of cases, and a comparison with existing evaluation methods and verification of disease specificity are required.

Assessment of dyspnea and dynamic hyperinflation in male patients with chronic obstructive pulmonary disease during a six minute walk test and an incremental treadmill cardiorespiratory exercise test

Abstract: Dynamic hyperinflation occurs in male COPD patients during submaximal exercise such as the 6MWT. This phenomenon is more pronounced after incremental CPET on a treadmill. Despite being dyspnea the dominant limiting symptom for both tests, we observed different physiological responses.
