I walked in on my dad, looking like he was dead (eyes open, but lifeless) He was suffering a full cardiac arrest. I called 911 and gave him chest compressions for 10 minutes until EMTs arrived. When they got there they told me his heart and lungs had stopped (full cardiac arrest) and they were struggling getting a pulse. I thought no way this is it and he did end up getting a pulse, being transported to the hospital and having his heart operated on. He survived!
