Hi, im looking for an answers. My mum has been in icu for 2 weeks now and theres been no signs of improvements.. she went into theatre on her 9th day of being on the ventilator to have a trachestomy done however she had a heart attack! On her 11th day of being in icu they took her for the trachestomy which was a success however her heart rate is not stable. Shes been off sedation for 2 days now and is not showing any signs of being awake, she opens her eyes and yawns however does not listen to commands? Does anyone know why and what is wrong? Why is she not awake yet.
