The correct answer is: The actual pressure is about $1.25$ times the atmospheric pressure
Blood pressure is gauge pressure $=190 \mathrm{~mm} \mathrm{Hg}$
Atmospheric pressure $=760 \mathrm{~mm} \mathrm{Hg}$
Actual pressure $=190+760 \mathrm{~mm} \mathrm{Hg}=950 \mathrm{~mm} \mathrm{Hg}=1.25 \times 760 \mathrm{~mm} \mathrm{Hg}$
