Can MIMIC-IV clinical data be combined with MIMIC-IV Waveform data for ventilator weaning prediction?

Hi,

I am working on a research project on predicting successful ventilator weaning using MIMIC-IV data.

I am currently using MIMIC-IV clinical data, including ventilator parameters, vital signs, laboratory measurements, and SBT-related information. I am also interested in using MIMIC-IV Waveform data, particularly respiratory and ventilator waveforms.

I would like to clarify the following:

1. Can MIMIC-IV clinical data and MIMIC-IV Waveform data be reliably combined for the same patient and ICU stay?

2. Can the waveform data be linked to the clinical data using subject_id, hadm_id, stay_id, and timestamps?

3. If I identify an SBT event from the clinical data, can I identify the corresponding respiratory/ventilator waveform during the same SBT period?

4. Does the MIMIC-IV Waveform Database contain respiratory/ventilator waveforms covering SBT periods?

5. Is there a recommended method or existing code for synchronizing the waveform data with MIMIC-IV clinical data?

My goal is to combine clinical features with waveform-derived features for ventilator-weaning prediction. I would appreciate any guidance on whether this is feasible and how these two datasets should be matched.

Thank you.
