Peri-intubation hypotension, reported in ≥ 40% of cases, is strongly associated with increased morbidity and mortality.

This review synthesizes current knowledge on the epidemiology, risk factors, and pathophysiology of peri-intubation hemodynamic deterioration. We review targeted strategies for hemodynamic optimization of physiologic parameters before intubation. These include volume expansion with fluid resuscitation, vasopressor utilization, selection of pharmacologic agents, invasive hemodynamic monitoring, and advanced preoxygenation techniques. In selected high-risk patients, we also discuss the potential role of extracorporeal membrane oxygenation as an adjunctive or rescue therapy.

Secondary outcomes included oral corticosteroid (OCS) use and medication persistence (analysed using Kaplan-Meier curves). For each treatment comparison, propensity scores were generated and confounding between baseline group characteristics was adjusted via inverse probability of treatment weighting, separately carried out for each study outcome.

Annual per-person rates of exacerbation were numerically similar in the while on-treatment population (measuring outcome until ICE; FF/VI, 0.1356; BUD/FOR, 0.1583 [P = 0.3023]). Patients who continued initiation treatment for 1 year without interruption had significantly lower annual per-person exacerbation rates with FF/VI (0.0722 [n = 425]) versus BUD/FOR (0.2258 [n = 546]) (rate ratio 0.3197 [P = 0.0003]). Patients indexed on FF/VI had significantly fewer OCS prescriptions and lower OCS dosage versus BUD/FOR (respective coefficients: - 0.29 [P = 0.0352]; 0.41 [P = 0.0004]) and improved treatment persistence (hazard ratio: 0.62 [P < 0.0001]).</p><p><strong>Conclusions: </strong>Patients who continued initiation treatment for a year without interruption had reduced exacerbation rates with FF/VI versus BUD/FOR.

POCs and controls were tested at device-specific settings 2, 3, 5, and 6. One-way analysis of variance (ANOVA) assessed FiO<sub>2</sub> differences when more than two groups were compared; independent t tests were used for two-group comparisons.</p><p><strong>Results: </strong>Wall oxygen generally delivered higher FiO<sub>2</sub> across all settings and respiratory rates. At 40 breaths/min and setting 2, however, the CAIRE FreeStyle<sup>®</sup> Comfort<sup>®</sup> with autoSAT<sup>®</sup> delivered a slightly higher FiO<sub>2</sub> than wall oxygen (0.25 vs. 0.24, p < 0.01). Among POCs, the CAIRE FreeStyle<sup>®</sup> Comfort<sup>®</sup> (with or without autoSAT<sup>®</sup>) achieved the highest FiO<sub>2</sub> values at elevated respiratory rates, while devices like the Inogen G4<sup>®</sup> and G5<sup>®</sup> performed more variably and showed reduced oxygen delivery at higher breathing frequencies.</p><p><strong>Conclusions: </strong>Wall oxygen and standalone concentrators consistently outperformed POCs across most breathing conditions. While the CAIRE FreeStyle<sup>®</sup> Comfort<sup>®</sup> with autoSAT<sup>®</sup> offered relative advantages at high respiratory rates, most POCs may not adequately sustain oxygenation during exertion or stress. These findings inform home oxygen therapy decisions, emphasizing the importance of device selection based on respiratory demand. Clinical validation of these bench findings is warranted.</p>","PeriodicalId":20919,"journal":{"name":"Pulmonary Therapy","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145070484","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
