A takeaway I have from this presentation is that as long as cpr is being administered it can prolong someone’s life for hours. I also didn’t know that cpr was to keep the heart pumping I thought it was only to keep the lungs pumping. In cpr I found it shocking how easy it is to break women’s ribs i knew you had to for cpr to work. With this presentation I can now analyze evidence to make judgments for the proper precautions to save someone’s life using cpr
