The 2019 SARS-CoV2 virus presented a capacity demand scenario for Yale New Haven Hospital. The response was created with a focus on clinical needs, but was also driven by the unique characteristics of the buildings within our institution. These physical characteristics were considered in the response as a safety measure as little was known about the transmissibility risk in the acute hospital setting of SARS-CoV2 at the time of response.

Introduction: Non-invasive ventilation (NIV) is used in cystic fibrosis (CF) to support airway clearance techniques (ACTs) by augmenting tidal volumes and reducing patient effort. However, the evidence base for this is limited. We hypothesised that NIV, in addition to usual ACT, would increase sputum clearance.

Key Points: There have been significant advances in both inhalation medicines and delivery devices with "intelligent nebulisers" and "dry-powder inhalers" becoming commonplace in CF care.Inhaled medicines generate high levels of a drug within the airways with limited systemic effects, offering safe and convenient antibiotic and mucolytic therapy for individuals with CF.Variations in adherence are not unique to CF; however, treatment burden is high and therefore fast inhaled drug delivery devices may assist individuals in completing the prescribed treatment regimes.

Background: There is no published literature on the frequency of use of non-invasive ventilation (NIV) with airway clearance techniques (ACT) throughout the cystic fibrosis (CF) population; 3.9% (191 people of 5062 registered) of the United Kingdom CF population older than 16 years are reported to use NIV in registry data; however, it is not specified if this is for ACT or respiratory failure. Using NIV with ACT decreases work of breathing and fatigue during in-patient admissions for CF patients.
