Because the flow is high, it can deliver more oxygen to the lungs and make breathing easier by reducing the effort needed to breathe. However, the best strategy to determine the best oxygen flow rate remains uncertain. Reducing flow rates prematurely can increase work of breathing and prolong ICU stay, while unnecessary prolongation can increase costs. Currently, evidence to guide titration is limited.\n\nHeart rate variability is the natural variation in the time between each heartbeat. Heart rate variability reflects the level of autonomic nervous system activity in response to stress. The autonomic nervous system is the part of the nervous system that automatically controls how heart rate speeds up and slows down. When heart rate variability is higher, it indicates that the system is able to adjust to changes in the body, including stress. However, when heart rate variability is low, it indicates that the system is constrained and in a state of stress.\n\nThe VARIATION study is designed to characterize how heart rate variability goal of this observational study is to learn whether heart rate variability can serve as a marker of the appropriateness of high flow nasal cannula flow support during flow titration in patients with respiratory failure.

Anxiety, agitation, dyspnea, and poor tolerance of respiratory support may compromise treatment adherence and increase the risk of respiratory deterioration and endotracheal intubation. Appropriate sedation may improve patient comfort, facilitate respiratory support, and reduce complications. However, sedation in non-mechanically ventilated ICU patients remains challenging because excessive sedation may lead to respiratory depression or hemodynamic instability.\n\nPropofol is commonly used for ICU sedation because of its rapid onset and controllable depth of sedation. Nevertheless, propofol is associated with several adverse effects, including respiratory depression, hypotension, and injection pain, which may limit its use in patients without invasive mechanical ventilation.\n\nCiprofol is a novel short-acting intravenous sedative that acts as a gamma-aminobutyric acid type A (GABA-A) receptor agonist and is structurally related to propofol. Previous studies have demonstrated that ciprofol has rapid onset, predictable sedation, less injection pain, and a potentially lower incidence of respiratory depression and hemodynamic instability compared with propofol. Clinical studies have shown favorable safety and efficacy profiles of ciprofol in procedural sedation, anesthesia induction, and sedation in mechanically ventilated ICU patients. However, evidence regarding its use in ICU patients receiving non-mechanical ventilation is still limited.\n\nThis study aims to compare the effectiveness and safety of ciprofol versus propofol for sedation in adult ICU patients who are not receiving invasive mechanical ventilation. The study will be conducted as a multicenter retrospective cohort study involving approximately 30 tertiary hospitals in China. Adult ICU patients treated between January 1, 2022 and July 30, 2024 who received intravenous sedation with either ciprofol or propofol while receiving non-invasive respiratory support (including NIV, HFNC, or conventional oxygen therapy) will be included.\n\nThe primary outcomes are sedation success rate and the incidence of respiratory depression. Sedation success is defined as maintaining the Richmond Agitation-Sedation Scale (RASS) within the target range of -2 to +1 for at least two consecutive hours without discontinuation of the sedation regimen or switching to another sedative. Respiratory depression will be defined based on predefined criteria including severe hypoxemia, markedly reduced respiratory rate, abnormal end-tidal carbon dioxide levels, or apnea.\n\nSecondary outcomes include endotracheal intubation rate during the sedation period, ICU length of stay, ICU mortality, and the requirement for vasoactive agents. Propensity score matching and multivariable statistical models will be used to adjust for baseline differences and potential confounders between treatment groups.\n\nThis real-world study aims to provide evidence regarding the clinical effectiveness and respiratory safety of ciprofol compared with propofol for sedation in ICU patients without invasive mechanical ventilation.
