Functional Examination of the Upper and Lower Airways in Asthma and Respiratory Allergic Diseases: Considerations in the Post-SARS-CoV-2 Era.

Airway examination procedures can potentially transmit infectious diseases to patients and to the health care professionals who perform them via various mechanisms. The COVID-19 pandemic has halted most of the activity of the clinics and laboratories involved in assessment of lung and nasal function, and clear recommendations in this regard have been made. Today, we still do not know for sure what its consequences will be in the short or long term, since important gaps remain in our knowledge of aspects as fundamental as virus transmission mechanisms, pathophysiology, immune response, and diagnosis. In this review, we study the examination techniques used to assess patients with respiratory allergy, asthma, and associated diseases during this period and highlight their possible advantages and disadvantages. Therefore, we focus on exploring the entire upper and lower airways, from the perspective of the safety of both health professionals and patients and their specific characteristics. We also analyze the intrinsic value of these interventions in terms of diagnosis and patient management. The changing situation of COVID-19 may mean that some of the assertions presented in this review will have to be modified in the future. While we seek to ensure a consistently broad approach, some differences in operational details may apply owing to local regulations.

Las técnicas de examen de las vías respiratorias son procedimientos que pueden transmitir enfermedades infecciosas, por diversos mecanismos, tanto a los pacientes, como a los profesionales de la salud que las realizan. La situación de pandemia debido a la enfermedad COVID-19 prácticamente ha detenido la mayor parte de la actividad de los laboratorios de función pulmonar y nasal, con recomendaciones, específicas, de múltiples sociedades y guías nacionales e internacionales. Continuamos viviendo las distintas olas de la pandemia y todavía no sabemos con certeza, cuáles serán sus consecuencias a corto o largo plazo, pues existen lagunas importantes en el conocimiento de aspectos tan fundamentales como los mecanismos de transmisión del virus, su fisiopatología y respuesta immune, o su diagnóstico.En esta revisión examinaremos las diferentes técnicas de examen disponibles en la evaluación de pacientes que sufren enfermedades alérgicas como la rinitis o el asma y enfermedades asociadas a ellas, destacando sus posibles ventajas y desventajas, en esta era que estamos viviendo tras la aparición del SARS CoV-2. Por esta razón, queríamos centrarnos en explorar todas las vías aéreas superiores e inferiores. Lo haremos desde la perspectiva de la seguridad tanto de los profesionales de la salud como de los pacientes y sus características específicas. Paralelamente abordaremos el análisis del valor intrínseco que proporcionan estas intervenciones desde el punto de vista tanto del diagnóstico como del tratamiento de estos pacientes. La situación cambiante de esta enfermedad puede causar en el futuro, modificaciones de las afirmaciones presentadas en esta revisión. Si bien esta guía busca garantizar un enfoque amplio y consistente, puede ser necesario aplicar algunas diferencias en los detalles operativos, debido a las distintas regulaciones o situaciones locales
