Single-Breath Counting Test to Start Non-Invasive Respiratory Support in COVID-19 Patients: Early Detection and the Eternal Dilemma. Comment on Longhitano et al. Single-Breath Counting Test Predicts Non-Invasive Respiratory Support Requirements in Patients with COVID-19 Pneumonia. 2022, , 179.

We have read this study, in which the predictive role of a single-breath counting test (SBCT) to foresee the need of non-invasive respiratory strategies (NIRS) in patients with COVID-19 has been explored, with great interest [...

Spontaneous Evolution of COVID-19 Lung Sequelae: Results from a Double-Step Follow-Up.

Background: Few studies have reported a double-step follow-up of patients after hospitalization for COVID-19.

Objectives: We designed an observational double-step follow-up study with a clinical, functional, and radiological evaluation at 2 and 6 months after COVID-19. The primary outcome was to describe symptoms, spirometry, and 6-minute walking test (6MWT) at 2 and 6 months.

Noninvasive ventilation and renal replacement therapy in do-not-intubate order critically ill patients: A brief report.

Introduction: Multiple organ failure has been considered a contraindication for noninvasive ventilation (NIV).

Materials And Methods: We described the outcome of Do-not-Intubate (DNI) patients with acute respiratory failure, treated with NIV and, subsequently, necessitating renal replacement therapy (RRT).

Results And Discussion: Seven patients admitted to our Respiratory Intensive Care Unit, developed Acute Kidney Injury (AKI) during NIV treatment and received RRT for 12.
