Overview
Brief Summary
The primary purpose of this study is to explore the feasibility and safety of normobaric oxygen therapy (NBO) under pre-hospital condition in patients with suspected stroke.
Detailed Description
Despite the application of thrombolytic drugs and endovascular treatment, there is still a gap between the successful recanalization and ideal clinical outcomes for stroke patients. Neuroprotective treatment is considered as a promising adjuvant to ameliorate this situation. Previous researches demonstrated the neuroprotective effects of Normobaric Hyperoxia (NBO) in animal models from multiple perspectives. Moreover, NBO is distinctive for its ubiquity, conveniency, high compatibility, and wide adaptability, making it superior to other neuroprotective interventions in a pre-hospital setting. Therefore, the investigators conducted this pilot study to further explore the feasibility and safety of NBO under a pre-hospital condition in patients with suspected stroke.

Arms & Interventions
Normobaric Oxygen Inhalation Group
Participants in the intervention group will receive oxygen inhalation through a mask at a rate of 10 L/min at 1 absolute atmosphere pressure (1 ATA = 101.325 kPa) after randomization until adimisson to the hospital. Participants will subsequently receive standard diagnosis and treatment service according to the guidelines during hospitalization.
Intervention: NBO
