Nasal high flow therapy use in wards in patients with chronic obstructive pulmonary disease may spare ICU resources.

Nasal high flow therapy has been previously studied for the management of acute hypoxic respiratory failure in patients with chronic obstructive pulmonary disease but the data regarding its use outside of the intensive care unit are sparse. We aimed to evaluate safety and efficacy of nasal high flow therapy outside of the intensive care unit in patients with acute hypoxic respiratory failure and known chronic obstructive pulmonary disease. We conducted a retrospective matched historic cohort study of adult patients with diagnosed chronic obstructive pulmonary disease presenting with acute hypoxic respiratory failure between December 2017 to June 2019, after the initiation of a new protocol, which allowed patients to be managed with nasal high flow therapy on the medical/surgical wards instead of transferring them to the ICU per prior standard of care.

Pentoxifylline or theophylline use in hospitalized COVID-19 patients requiring oxygen support.

Introduction: The phosphodiesterase inhibitors theophylline and pentoxifylline have anti-inflammatory properties that may make them useful in COVID-19 pneumonia. We conducted a retrospective review of hospitalized COVID-19 patients requiring oxygen who received these drugs.

Objectives: To examine the potential efficacy and safety of theophylline and pentoxifylline in COVID-19 pneumonia patients.

Implementation of High-Flow Nasal Cannula Therapy Outside the Intensive Care Setting.

Background: High-flow nasal cannula (HFNC) is an option for respiratory support in patients with acute hypoxic respiratory failure. To improve patient outcomes, reduce ICU-associated costs, and ease ICU bed availability, a multi-phased, comprehensive strategy was implemented to make HFNC available outside the ICU under the supervision of pulmonology or trauma providers in cooperation with a dedicated respiratory therapy team. The purpose of this study was to describe the education and implementation process for initiating HFNC therapy outside the ICU and to convey key patient demographics and outcomes from the implementation period.
