At 1;45 bp was 150 over 1016 pulse 109 . at 2;46 bp was 166 over 93 pulse of 123. Mom has been on high blood pressure meds for years. Her history includes panic attacks (about 1 every 3 or four months apart one earlier this week). One kidney removed about ten years ago. Other than that she is mainly just naturaly aging with slow steps and a determination not to leave the safe3 zone ofd home, God bless her. Should we take her to ER and at what point?
