  2. Steps used to decrease complication of central venous access lines
    • 1.Not done to all
    • patient to check the preload of the heart. (11-16cm H2O – if intubated  21 – 26cmH20) or (8-12mmHg)

  29. Treatment for which complication?
    -Inflate the tracheostomy balloon cuff to high pressure in order to attempt compression of the innominate artery.  

    -If needed, remove the tracheostomy, and place a finger through the tracheostomy site in order to apply direct pressure anteriorly for compression of the innominate artery.  

    -Sterile preparation of the patient for a median sternotomy should include the assistant's hand in the operative field. 

    -Once exposed, surgically ligate the innominate artery proximally and distally to the injury.
