					Blood Pressure
               What Is It?
•   Blood pressure is the force of the blood
    pushing against the walls of the arteries
•   The heart muscle contracts and sends
    blood into the system, the blood flows
    and presses on the arterial walls
•   The heart muscle relaxes but since blood
    is still in the system, some pressure
    remains
        Systolic vs Diastolic
• Your blood pressure is at its highest when
  the heart beats, pumping the blood
  through the body. This is called systolic
  pressure. It’s the top number
• When the heart is at rest, between beats,
  your blood pressure falls. This is the
  diastolic pressure. It’s the bottom number
      What affects Your BP?
• Blood pressure changes during the day.
• It is lowest as you sleep and rises when
  you get up.
• It also can rise when you are excited,
  nervous, or active.
• Other things can affect it like. . .
                        Causes of HBP
• Diet
   – High fat
         • Fat deposits on the arterial walls making them less elastic, pressure
           builds up (arteriosclerosis)
   – High sodium
         • Extra fluid in the system means extra work pushing it though
• Lack of exercise
   – More fat in blood
   – Weight gain
• Being overweight
   – Extra work/strain on system
   – Dietary contributions
• Disease
   – CAD
• Genetics
     Normal Blood Pressure
• 110/70


       High Blood Pressure

  •140/90
       High Blood Pressure
• A blood pressure of 140/90 or higher is
  considered high blood pressure.
• Bottom number is critical
• It’s understandable the pressure would be
  higher when the heart is contracting
• Bad thing when the pressure remains high
  when the heart is in a relaxed state!
• So 140/70 is not quite as bad as 120/95!
         Symptoms of HBP
• Usually, there are no specific symptoms
  which indicate that someone has high
  blood pressure.
• But some symptoms reported include
  sleep disturbance, emotional upsets, and
  dry mouth in those with higher pressures.
           Sodium and HBP
• The current recommendation is to consume less
  than 2.4 grams (2,400mg) of sodium a day.
• That equals 6 grams (about 1 teaspoon) of table
  salt a day.
• This includes ALL salt and sodium consumed,
  including that used in cooking and at the table.
HBP patients should eat less salt and sodium,
      1,500 mg of sodium
                Exercise
• 20 minutes a day in your THR 3X a week
  can contribute to lower blood pressure
• More exercise when combined with weight
  loss and a better diet would result in more
  improvements!
