Gas Exchange and Ventilatory Efficiency During Exercise in Pulmonary Vascular Diseases.
Ventilatory inefficiency (high V'E/V'CO2) and resting hypocapnia are common in pulmonary vascular disease and are associated with poor prognosis. Low resting PaCO2 suggests increased chemosensitivity or an altered PaCO2 set-point. We aimed to determine the relationships between exercise gas exchange variables reflecting the PaCO2 set-point, exercise capacity, hemodynamics and V'E/V'CO2. ⋯ Resting hypocapnia is associated with worse cardiac function, more ventilatory inefficiency and reduced exercise capacity. This could be explained by elevated chemosensitivity and lower PaCO2 set-point. Maximal PETCO2 may be a useful non-invasive marker of PaCO2 setpoint and disease severity even with submaximal effort.

Practice GuidelineSEPAR and AEER consensus recommendations on the Use of Bronchoscopy and Airway Sampling in Patients with Suspected or Confirmed COVID-19 Infection.
This consensus document has been drawn up by the Techniques and Transplantation and Nursing areas of the Spanish Society of Pulmonology and Thoracic Surgery (SEPAR) and the Spanish Society of Respiratory Endoscopy (AEER) with the aim of providing information on the safe and effective use of bronchoscopy in patients with suspected or confirmed COVID-19 infection. Our priority is to ensure the safety of our patients, the health workers caring for them, and the community in general. At this stage in the pandemic, our information on the use of bronchoscopy in patients of this type is based on the experience of hospitals in other countries, and scientific publications are scarce. The objective of this document is to compile these experiences, based on recommendations from official agencies, in a document offering guidance in daily clinical practice.
