Overview

Brief Summary The goal of this clinical trial is to compare whether the novel high-performance emergency transport ventilator (TV80) differs from the intelligent transport ventilator (HAMILTON-T1) in terms of oxygenation stability when used for transporting mechanically ventilated patients. It will also collect data on the novel ventilator's performance and safety in multiple transport scenarios. The main questions it aims to answer are: 1. Does the novel high-performance emergency transport ventilator (TV80) show non-inferior oxygenation stability (measured by the difference in oxygenation index before and after transport) compared with HAMILTON-T1 in transporting mechanically ventilated patients? 2. What differences exist between the two ventilators in secondary outcomes such as transport preparation time, changes in PaCO2 and pH before and after transport, and variations in tidal volume, FiO2, heart rate, oxygen saturation, and mean arterial pressure? We will randomly assign eligible mechanically ventilated patients requiring intra-hospital or inter-hospital transport to either TV80 or HAMILTON-T1 group at a 1:1 ratio, and compare the differences in the above outcomes between the two groups. Participants will: 1. Be screened for eligibility based on inclusion and exclusion criteria, and their legal representatives will sign the informed consent form. 2. Be randomly assigned to use either TV80 or HAMILTON-T1 group during transport. 3. Undergo blood gas analysis 1 hour after airway intervention stabilization (before transport) and within 1 hour after transport completion to calculate the oxygenation index and changes in PaCO2 and pH. 4. Have transport preparation time recorded (from the start of transport preparation, such as suctioning and pipeline organization, to the confirmation of stable vital signs before transport). 5. Have parameters such as tidal volume, FiO2 (recorded by the ventilator) and heart rate, oxygen saturation, mean arterial pressure (monitored by a incorporated module in TV80 or portable monitor along with HAMILTON-T1) recorded during transport to calculate their variations. 6. Be monitored for adverse events during transport; if severe adverse events occur, the trial will be stopped immediately, and appropriate treatment measures will be taken.

Intelligent emergency ventilator for transportDEVICE

In this study, eligible patients are first evaluated by research staff to confirm that they meet the inclusion criteria. Once eligibility is established, the research team accesses the electronic data capture (EDC) system via a WeChat QR code, where patients are randomly assigned in a 1:1 ratio to either the domestic ventilator group (TV80) or the imported ventilator group (HAMILTON-T1). After randomization, both patient and ventilator preparation procedures are conducted according to a standardized protocol.

Outcomes

Primary Outcomes

Difference in PaO2/FiO2 before and after transferring

Arterial blood samples will be collected within 1 hour before and 1 hour after transport. Blood gas analysis will be performed to obtain PaO2 and FiO2 values and calculate the oxygenation index. The difference between the two indices is then determined.

Time frame: Within 1 hour before and 1 hour after transport

Secondary Outcomes

Variation in heart rate before and after transferring

From the beginning to the end of transport, obtain data recorded manually or from the ventilator to determine the minimum and maximum heart rates during the entire process, and calculate the difference between them

Time frame: Procedure (From the beginning to the end of transport)

Variation in SPO2 before and after transferring

From the beginning to the end of transport, retrieve data recorded manually or from the ventilator to identify the minimum and maximum oxygen saturation levels throughout the process, and calculate the difference between them

Time frame: Within 1 hour before and 1 hour after transport

Variation inPaCO2 before and after transferring

Arterial blood samples are collected within 1 hour before and 1 hour after transport. Blood gas analysis is performed to obtain PaCO₂ values before and after transport, and the difference between them is calculated

Time frame: Within 1 hour before and 1 hour after transport

Variation in tidal volume before and after transferring

From the beginning to the end of transport, retrieve data from the ventilator to identify the minimum and maximum delivered tidal volumes throughout the process, and calculate the difference between them

Time frame: Within 1 hour before and 1 hour after transport

Difference in pH before and after transferring

Arterial blood samples are collected within 1 hour before and 1 hour after transport. Blood gas analysis is performed to obtain pH values before and after transport, and the difference between them is calculated.

Time frame: Within 1 hour before and 1 hour after transport

Variation in FiO2 before and after transferring

From the beginning to the end of transport, retrieve data from the ventilator to identify the minimum and maximum delivered FiO₂ values throughout the process, and calculate the difference between them

Time frame: Within 1 hour before and 1 hour after transport

Variation in mean arterial pressure and after transferring

From the beginning to the end of transport, retrieve data recorded manually or from the ventilator to identify the minimum and maximum mean arterial pressures throughout the process, and calculate the difference between them

Time frame: From the beginning to the end of transport

Preparing time for transferring
