Well an hour later shes completely hypoxic, goes blue and arrests. No warning signs at all, I’d got the other nurse to check her really closely because of my gut feeling, and there wasn’t a reason to suspect she would arrest until she went blue and collapsed. We did CPR and we get her to ICU and she survived. We have good reason to believe that all the rubbish she was coughing up from the infection blocked off her upper airway causing the hypoxic arrest. She happened to be nearby once, and she came over, used her key to get in after he didn’t respond to her knocking (because he couldn’t hear her), and she watched him slamming his vacuum into our wall for 20 straight minutes
