ATS — ATS 2026 preoxygenation before intubation
ATS, 2026
Use HFNC or NIV rather than conventional oxygen for preoxygenation before intubation to reduce peri-intubation hypoxemia. The guideline does not establish that HFNC is superior to NIV. Choose the interface according to physiology, tolerance and the airway plan.
Clinical Context & Relevant Topics (6)
Disease ReferenceCore taxonomy (Types I–IV), alveolar gas exchange physiology, work-of-breathing mechanics, and escalation thresholds in acute respiratory failure.
Pathophysiologic mechanisms (shunt vs V/Q mismatch), dynamic ROX index trajectories, P-SILI prevention, and evidence-based oxygen escalation ladders.
Mechanism-based diagnosis of acute and acute-on-chronic hypercapnia, controlled oxygen, NIV, invasive ventilation, auto-PEEP troubleshooting, neuromuscular monitoring, and post-acute planning.
Pathophysiology of acute-on-chronic hypercapnia, controlled oxygen targets (88–92%), evidence-based NIV, and auto-PEEP matching mechanics.
