You may also want to take a look at the MIMIC database, which offers deidentified health data associated with ~40,000 critical care patients (note you need to take CITI training for this, but the overhead is low)
https://mimic.physionet.org/
It is provided by the MIT Laboratory for Computational Physiology, who offer a range of very well curated datasets and tools in this domain (note curated does not mean clean), including the recently released eICU dataset (https://eicu-crd.mit.edu/), and some waveform data through PhysioNet (https://lcp.mit.edu/Physionet)
