Respiratory care

Noninvasive respiratory support (NRS) has been used to treat acute respiratory failure outside the ICU, but existing data have left many knowledge gaps for managing NRS in general wards. The primary objective of this study was to describe indications, duration of treatment, and outcomes of subjects treated with NRS outside the ICU. The secondary objective was to compare outcomes based on age < 80 or ≥ 80 y. ⋯ In a real-life setting outside the ICU, NIV and CPAP managed by a rapid response team with a daily visit in collaboration with ward staff highly experienced in NRS allowed us to treat the subjects without major complications. Post-discharge 1-year mortality was higher in the subjects ≥ 80 y old treated with NIV for acute hypercapnic respiratory failure.

Nebulized therapies form an important component of treatment in people with cystic fibrosis (CF). It is important for people with CF to continue to take their nebulized medications when traveling. ⋯ This study identified that nebulizer care and hygiene are less than optimal when traveling as well as identifying a worrying trend of taking a "nebulizer vacation." People with CF need to be aware of risks to their health in being nonadherent with their nebulized medication(s) while traveling as well as risks of acquiring a new pathogen through suboptimal cleaning/disinfection/drying management of their nebulizer. CF multidisciplinary teams should emphasize the importance of sustaining nebulized treatments when traveling and practicing effective nebulizer washing, disinfection, and drying procedures.

Prone positioning reduces mortality in patients with moderate/severe ARDS. It remains unclear which physiological parameters could guide clinicians to assess which patients are likely to benefit from prone position. This study aimed to determine the association between relative changes in physiological parameters at 24 h of prone positioning and ICU mortality in adult subjects with ARDS. ⋯ In subjects with ARDS receiving prone positioning, a relative decline in the ventilatory ratio at 24 h was associated with lower ICU mortality.

When helmet CPAP is performed using a Venturi system, filters are frequently interposed in the respiratory circuit to reduce noise within the helmet. The effect of the interposition of these filters on delivered fresh gas flow and the resulting FIO2 is currently unknown. ⋯ The use of filters during helmet CPAP reduced the flow delivered to the helmet and, consequently, modified FIO2 . If filters are applied, an adequate gas flow should be administered to guarantee a constant CPAP during the entire respiratory cycle and avoid rebreathing. Moreover, it might be important to measure the effective FIO2 delivered to the patient to guarantee a precise assessment of oxygenation.

Review
The Use of Mechanical Insufflation-Exsufflation in Invasively Ventilated Critically Ill Adults.
Mechanical insufflation-exsufflation (MI-E) is traditionally used in the neuromuscular population. There is growing interest of MI-E use in invasively ventilated critically ill adults. We aimed to map current evidence on MI-E use in invasively ventilated critically ill adults. ⋯ Only 3 studies reported the occurrence of adverse events. From qualitative data, the main barrier to MI-E use in this subject group was lack of knowledge and skills. We concluded that there is little consistency in how MI-E is used and reported, and therefore, recommendations about best practices are not possible.
