Development and Preliminary Validation of Intelligent Video Laryngoscope for Emergency Use (MEASURE-ILD)
Development of an Intelligent Video Laryngoscope and Preliminary Verification for Emergency Application
The investigators are developing a video laryngoscope equipped with artificial intelligence technology to enable automatic identification of key airway anatomical structures and real-time guidance during intubation, with the aim of improving the success rate and efficiency of endotracheal intubation in emergency settings.

Descrizione
Inclusion Criteria:
- Patient inclusion criteria: Adult patients in critical condition requiring endotracheal intubation via laryngoscopy (age ≥ 18 years).
Exclusion Criteria:
- pregnant women, prisoners, recent history of airway surgery, oral or pharyngeal malformations, inability to perform randomization due to the need for emergency endotracheal intubation, or when the investigator deemed it necessary or contraindicated to use AIVL, VL, or DL during the first intubation attempt.

Gruppo di partecipanti / ArmGruppo di partecipanti / Arm |
Intervento / TrattamentoIntervento / Trattamento |
|---|---|
|
Comparatore attivo: Video Laryngoscope(VL)
Participants randomized to this arm (n=60) will undergo the first endotracheal intubation attempt using a conventional video laryngoscope (VL), without AI-assisted anatomical identification or intubation guidance. |
A conventional video laryngoscope will be used for the first endotracheal intubation attempt. The device displays the airway image without AI-assisted identification of anatomical structures or real-time AI intubation guidance. |
|
Sperimentale: AI-assisted Video Laryngoscope (AIVL)
Participants randomized to this arm (n=60) will undergo the first endotracheal intubation attempt using an AI-assisted video laryngoscope (AIVL), which provides real-time identification of airway anatomical structures and intubation guidance. Operators will receive standardized training on the device controls, guidance interface, and image display before use. Operators may decide whether to follow the AI guidance. |
When using the AIVL for the first attempt at laryngoscopy intubation, the operator shall receive pre-procedural training, which primarily covers the functional buttons, the prompt interface, and image display. |
