Dysfunctional breathing diagnosed by cardiopulmonary exercise testing in 'long COVID' patients with persistent dyspnoea

Isabelle Fresard et al.

Summary: Among 51 patients living with 'long COVID' and persistent dyspnoea, cardiopulmonary exercise testing revealed that nearly one-third of patients had dysfunctional breathing (DB), a larger proportion had respiratory limitation (RL), and only a small number had O2 delivery/utilisation impairment (D). Patients with DB were typically younger, had milder initial infections, better transfer capacity for carbon monoxide, higher oxygen consumption, better ventilatory efficiency slope, and higher oxygen saturation compared to those with RL.

Cardiopulmonary Exercise Testing in the Assessment of Dysfunctional Breathing

Maria F. Ionescu et al.

Summary: Dysfunctional breathing (DB) is a condition that affects individuals in various situations, including athletes, and can be diagnosed and managed using cardiopulmonary exercise testing (CPET). Proper recognition of DB is important for treatment and can lead to significant benefits for individuals.

Respiratory rehabilitation for Covid-19 related persistent dyspnoea: A one-year experience

Benoit Bouteleux et al.

Summary: This study included 39 patients with long Covid sequelae, most of whom were middle-aged with predominant symptoms of dyspnoea and fatigue. The results showed significant improvements in patients' functional capacity, exertional dyspnoea, and quality of life during the rehabilitation process.

Minute ventilation/carbon dioxide production in patients with dysfunctional breathing

Matthew Watson et al.

Summary: Dysfunctional breathing is a complex condition characterized by pathological changes in breathing that can lead to breathlessness. The ventilatory equivalent for CO2 (V-egCO2) is a physiological parameter that can assist in diagnosis, but is not a standalone diagnostic tool. Understanding the multidimensional aspects of dysfunctional breathing and utilizing V-egCO2 in a broader diagnostic algorithm can help accurately identify and manage individuals with this condition.

Phenotyping long COVID

Robert Naeije et al.

Summary: Patients recovering from acute SARS-CoV-2 infection often experience persistent symptoms lasting for months. Those with long COVID show abnormal cardiopulmonary exercise test profiles, indicating deconditioning and hyperventilation tendencies.
