Abstract PurposeThe scenario of global health crisis due to SARS-CoV-2 pandemia combined with the shortage of resources in many countries has justified numerous studies to design easily replicable and economic respiratory support devices. We have developed an adapted diving mask (ADM) to be used as an autonomous and safe respiratory support. The objective was to prove a minimum positive end expiratory pressure (PEEP) with the ADM without any adverse events.MethodsBench tests was done in 22 healthy volunteers with our ADM prototype. Expiratory-inspiratory flow and pressure were registered apart from blood and transcutaneous hypercapnia.ResultsThere were no statistically significant differences in the baseline analysis results and after therapy, except in pO2. Mean PEEP measured was 8.2 ± 4.2 cmH2O with a peak measured pressure of 20 cm H2O.ConclussionsThe ADM has shown good tolerance and a therapeutic manteining PEEP with no evidence of any deletereous effect or hypercapnia with its continuous use.

Abstract Background Noninvasive respiratory support devices may reduce the tracheal intubation rate compared with conventional oxygen therapy (COT). To date, few studies have compared high-flow nasal cannula (HFNC) use with noninvasive positive-pressure ventilation (NPPV). We conducted a network meta-analysis to compare the effectiveness of three respiratory support devices in patients with acute respiratory failure. Methods The Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, and Ichushi databases were searched. Studies including adults aged ≥ 16 years with acute hypoxic respiratory failure and randomized-controlled trials that compared two different oxygenation devices (COT, NPPV, or HFNC) before tracheal intubation were included. A frequentist-based approach with a multivariate random-effects meta-analysis was used. The network meta-analysis was performed using the GRADE Working Group approach. The outcomes were short-term mortality and intubation rate. Results Among 5507 records, 27 studies (4618 patients) were included. The main cause of acute hypoxic respiratory failure was pneumonia. Compared with COT, NPPV and HFNC use tended to reduce mortality (relative risk, 0.88 and 0.93, respectively; 95% confidence intervals, 0.76–1.01 and 0.80–1.08, respectively; both low certainty) and lower the risk of endotracheal intubation (0.81 and 0.78; 0.72–0.91 and 0.68–0.89, respectively; both low certainty); however, short-term mortality or intubation rates did not differ (0.94 and 1.04, respectively; 0.78–1.15 and 0.88–1.22, respectively; both low certainty) between NPPV and HFNC use. Conclusion NPPV and HFNC use are associated with a decreased risk of endotracheal intubation; however, there are no significant differences in short-term mortality.
