Checking responsiveness is the mainstay in cardiopulmonary resuscitation (CPR). It is rare in the clinical situation when the patient requires resuscitation despite the presence of wakefulness. We report a case in which the patient presented with flat arterial line and absence carotid pulse while he was awake. A thorough literature review will also be discussed.
