Acute meal ingestion, caffeine or nicotine use can all negatively affect BP readings, leading to errors in measurement accuracy. If the patient has a full bladder, that can lead to an error in systolic BP of between 4 mm Hg and 33 mm Hg, compared with the white-coat effect can have an error of up to 26 mm Hg.
Which is a common error in blood pressure measurement?
The most common error when using indirect blood pressure measuring equipment is using an incorrectly sized cuff. A BP cuff that is too large will give falsely low readings, while an overly small cuff will provide readings that are falsely high.
Which is a common error in blood pressure measurement quizlet?
A common error in blood pressure measurement includes: taking the blood pressure in an arm that is at the level of the heart. waiting less than 1 to 2 minutes before repeating the blood pressure reading on the same arm. deflating the cuff about 2 mm Hg per heart beat.
What causes false high blood pressure readings?
Improper BP measurement may result in falsely high readings, such as when the wrong-sized cuff is used, when patients have heavily calcified or arteriosclerotic brachial arteries, or in cases of white-coat hypertension (observed in 20-30% of patients ).
How can inaccurate blood pressure reading affect patient care?
In general practice, high BP values are used as a basis for the diagnosis of hypertension . Inaccurate or misleading BP values, therefore, can be detrimental to the quality of healthcare received by patients.
Is it OK to take blood pressure multiple times?
The first measurement should be in the morning before eating or taking any medications, and the second in the evening. Each time you measure, take two or three readings to make sure your results are accurate. Your doctor might recommend taking your blood pressure at the same times each day.
What is normal blood pressure by age?
Normal Blood Pressure By Age
What can cause a false low blood pressure reading quizlet?
Rationale: Using a blood pressure cuff that is too loose would cause the blood pressure to be inaccurately high. Using a blood pressure cuff that is too wide would cause the blood pressure to be inaccurately low.
What are the causes of a falsely high blood pressure reading quizlet?
Terms in this set (13)
- Cuff too wide. False-low reading.
- Cuff too narrow or too short. False-high reading.
- Cuff wrapped too loosely or unevenly. False-high reading.
- Deflating cuff too slowly. False-high diastolic reading.
- Deflating cuff too quickly. …
- Arm below heart level. …
- Arm above heart level. …
- Arm not supported.
Which of the following is a factor that would influence blood pressure?
Blood pressure increases with increased cardiac output, peripheral vascular resistance, volume of blood, viscosity of blood and rigidity of vessel walls. Blood pressure decreases with decreased cardiac output, peripheral vascular resistance, volume of blood, viscosity of blood and elasticity of vessel walls.
Is it normal for blood pressure to fluctuate?
Blood pressure changes naturally many times a day. Most changes are normal and predictable. When these spikes and valleys in your blood pressure occur, you may not experience unusual signs or symptoms. These fluctuations may be brief and fleeting.
Why is blood pressure lower the second time I take it?
Diastolic pressure (the second, lower number) reflects the pressure in the arteries when the heart rests between beats. Over eight years, more than 44,000 people in the study had a heart attack or stroke.
How long should you wait between blood pressure readings?
It is recommended to wait at least 1 minute between blood pressure (BP) readings.
What are two potential sources of error in BP?
Acute meal ingestion, caffeine or nicotine use can all negatively affect BP readings, leading to errors in measurement accuracy.
What happens to blood pressure after a meal?
When a person eats, their body redirects blood to the digestive tract to aid with digestion. This causes a temporary decrease in blood pressure elsewhere in the body. To compensate, blood vessels outside of the digestive tract constrict, causing the heart to beat faster and more forcefully.
Why is my blood pressure reading different every time?
Some variation in blood pressure throughout the day is normal, especially as a response to small changes in daily life like stress, exercise, or how well you slept the night before. But fluctuations that occur regularly over a number of doctor visits may indicate an underlying problem.
