Blood Pressure (Definition)

Blood pressure is a measurement of the force placed on the blood vessels and is comprised of the "systolic" pressure (the top number on a blood pressure meter) which is the peak pressure when the heart is pumping, and the "diastolic" pressure (the bottom number on a blood pressure meter) which is the pressure during the resting phase ...Read more

Blood pressure numbers explanation?

Blood pressure numbers explanation?

Top/Bottom: The top number (systolic) can be viewed as how hard the heart pumps blood into the body. The bottom number (diastolic) can be described as the pressure the body pushes back against the heart. Obviously the top number is higher, as the heart pushes harder to get the blood to flow. Both of these numbers are very important. ...Read more

BP definition.: The blood pressure is the resistance to blood flow through the body. The higher number is the resistance when the heart pumps, and the lower number is the resistance when the heart relaxes and fills. High BP can lead to problems with the heart, kidneys, eyes, blood vessels and brain. ...Read more

High blood pressure?

What is high BP?: A level of blood pressure that has been proven to shorten ones life and a level of BP that if treated prolongs ones life. The best is to be below120/80. However for treatment we use 135/85 at home as high. At your age above 135/85 at home would be consider HTN that needs to be lowered. Always try DASH diet first. ...Read more

High blood pressure?

High blood pressure?

Yes? =140+/90+: If systolic (top #) is repeatedly 140 or higher and/or diastolic (bottom #) 90 or higher, then have hypertension (HTN) or high blood pressure. Need to document BP readings from same machine/cuff (home, at store, etc.) w/date & time of day. Take list to your dr for review and discussion of benefit of medication vs likelihood of lifestyle changes lowering bp. ...Read more

Can blood pressure affect pulse oximeter readings?

Can blood pressure affect pulse oximeter readings?

Not usually..: The only effect would be if the blood pressure is extremely low causing poor peripheral blood flow. In this instance, the pulse ox may be inaccurate. This could occur in shock situations. As long as the blood flow remains normal, the blood pressure will not affect pulse ox. ...Read more

How does the blood pressure cuff measure blood pressure?

How does the blood pressure cuff measure blood pressure?

See below: The cuff is put around the arm and inflated. The pressure is increased enough to totally cut off flow through the artery. When the cuff is deflated, sounds are heard when flow begins. That is the systolic pressure. When the cuff further deflates, eventually there is no collapse of the artery at all and then the sounds disappear or muffle. That is the diastolic pressure. ...Read more
