  1. Values are numbers and percentages. The categories for Respiratory deterioration and increased apnea report numbers of POWS spike and control times where this was the primary clinical correlation and no evaluation was performed for suspected or confirmed infection. The “other significant event category” included one event in each category where hypotension requiring treatment was documented, but no evaluation was performed for suspected infection or respiratory deterioration.
