Brain scans

The pulmonologist had dad's ventilator turned down to CPAP, meaning he's initiating his own breaths, and just getting a little help from the machine. His sedation has been weaned back completely, but he's still not responsive. He was given an EEG (which measures brain activity) and a head CT this afternoon, and we're just waiting for the results. We might have to wait until tomorrow - if that's the case, it's going to be a long night.
