Chapter 5: Blood Pressure Show
Blood pressure is reported in mm Hg (pronounced millimetres of mercury), in which the systolic is the numerator and diastolic is the denominator. See Table 5.1 for an overview of estimated blood pressure ranges for healthy individuals. Table 5.1: Estimated Blood Pressure Ranges (mm Hg)
Points to ConsiderThe average blood pressure for an adult is sometimes noted as 120/80 mm Hg. However, this is only an average and the healthcare provider needs to consider acceptable ranges for individual clients. For example, in adults, normal blood pressure can range from 95–145/60–90 mm Hg. The healthcare provider considers the client’s baseline blood pressure and the client’s current health state in conjunction with subjective data and other objective data. For example, a blood pressure of 90/50 mm Hg may be normal for a healthy, asymptomatic 20-year-old adult. Factors that influence blood pressure include age, sex, ethnicity, weight, exercise, emotions/stress, pregnancy, and diurnal rhythm as well as medication use and disease processes.
Points to ConsiderWhite coat syndrome refers to elevated blood pressure due to nervousness or anxiety when clients have their blood pressure taken by a healthcare provider. This occurs in approximately 20% of clients. Key message: have the client take their blood pressure at home with an automatic home blood pressure cuff and compare the findings. Alternatively, you can ask the client to sit quietly and leave the room while an automatic cuff takes a client’s blood pressure. The automatic cuff can be programmed to take three measurements and the blood pressure documented is an average of the three readings. Find out how to understand blood pressure readings and use our blood pressure chart to see how healthy your blood pressure is.What does a blood pressure reading look like?When you have your blood pressure measured, you will be given two numbers, a top number and a bottom number.
Blood pressure is measured in millimetres of mercury (mmHg). If the first number is 120 and the second number is 80, this would be written as 120/80mmHg, and you’d call it ‘120 over 80’. This video explains more about systolic and diastolic blood pressure. The blood pressure chartOnce you know your numbers, you can use the blood pressure chart to see what they mean and if your blood pressure is in the healthy range. The chart is suitable for adults of any age, as the cut-off point for diagnosing high blood pressure doesn’t change with age. How to use the blood pressure chart Simply find your top number (systolic) on the left side of the chart and your bottom number (diastolic) on the bottom. Where the two lines meet is your blood pressure. Download the chart. Blood pressure chart for adults - PDF [PDF 121KB] What do the readings mean?As a general guide: • 140/90mmHg or over – you may have high blood pressure • 120/80mmHg up to 140/90mmHg – pre-high blood pressure • 90/60mmHg up to 120/80mmHg – ideal blood pressure • 90/60mmHg or lower – you may have low blood pressure The video below explains how your blood pressure numbers are linked to the risk of stroke and other disease.
Diagnosing high or low blood pressureOnly one of your numbers needs to be higher than it should be to be diagnosed with high blood pressure, and only one needs to be lower than it should be to be diagnosed with low blood pressure. So if your top number is over 140 or the bottom number is over 90, you may be diagnosed with high blood pressure, regardless of the other number. If your top number is under 90 or your bottom number is under 60, you may be diagnosed with low blood pressure. Use the chart to see where your numbers sit. If your top number (systolic pressure) is consistently higher than 140mmHg, but the bottom number is healthy - this is known as Isolated Systolic Hypertension. If the bottom number (diastolic pressure) is consistently higher than 90mmHg but the top number is healthy - this is known as Isolated Diastolic Hypertension. Making sure your readings aren’t a one-off A single high reading doesn’t necessarily mean you have high blood pressure, as many things can affect your blood pressure throughout the day, such as the temperature, when you last ate, and if you’re feeling stressed. Your doctor or nurse will probably want to measure your blood pressure a number of times over a few weeks to make sure the reading wasn’t just a one off and that your blood pressure stays high over time. Read about how high blood pressure is diagnosed, getting a blood pressure check, the further tests you might have if you have a high blood pressure reading, and what it means if you’re diagnosed with high blood pressure. What is a good blood pressure and pulse?ideal blood pressure is considered to be between 90/60mmHg and 120/80mmHg. high blood pressure is considered to be 140/90mmHg or higher. low blood pressure is considered to be 90/60mmHg or lower.
What is normal blood pressure and pulse for a 70 year old?New Blood Pressure Standards for Seniors
The ideal blood pressure for seniors is now considered 120/80 (systolic/diastolic), which is the same for younger adults. The high blood pressure range for seniors starts at hypertension stage 1, spanning between 130-139/80-89.
What is a good pulse rate by age?Normal Heart Rate by Age Chart. What is a normal pulse rate?A normal resting heart rate for adults ranges from 60 to 100 beats per minute. Generally, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness. For example, a well-trained athlete might have a normal resting heart rate closer to 40 beats per minute.
