Browse categories and answer follow-up questions to refine your symptom profile.
Time critical priorities
Stroke pathway activation
Last known well time
Wake up or unwitnessed onset treated as last known well at sleep or baseline time
Symptom discovery time recorded separately
Glucose bedside
Hypoglycemia mimics and immediate correction threshold 3.0 mmol/L
Persistent neuro deficit after correction treated as possible stroke
Airway and ventilation
GCS decline
Aspiration risk with bulbar dysfunction
Hemodynamics
Hypotension evaluation for sepsis hemorrhage dysrhythmia
Avoid rapid blood pressure drops before imaging unless hypertensive emergency
Imaging clock
Noncontrast CT head immediate
CTA head and neck early for large vessel occlusion screening
Thrombolysis and thrombectomy eligibility snapshot
Time windows
IV thrombolysis window 4.5 hours from last known well
Endovascular thrombectomy window 6 hours standard
Endovascular thrombectomy window 6 to 24 hours with favorable imaging selection
Contraindication sweep
Active bleeding
Recent intracranial hemorrhage history
Recent major surgery or trauma
Current anticoagulant exposure
Monitoring and targets
Oxygenation
SpO2 target at least 94%
Routine oxygen avoidance if not hypoxemic
Temperature
Fever threshold 38.0 C
Antipyretic strategy for fever
Glucose
Hyperglycemia target 7.8 to 10.0 mmol/L
Hypoglycemia avoidance
Systems of care
Transfer and routing decisions
Large vessel occlusion suspicion
Direct routing to thrombectomy capable center when feasible
Do not delay IV thrombolysis for transfer logistics
Wake up or late window presentation
Advanced imaging access plan
Neurology and interventional consultation early
Time metrics for quality
Door to CT goal 20 minutes
Parallel processing for labs registration and IV access
Door to needle goal 60 minutes
Consent process minimized to essentials
Door to groin puncture goal 90 minutes for eligible transfers and arrivals
