What is a finger pulse transducer capable of determining?

What is a finger pulse transducer capable of determining?

What is a finger pulse transducer, together with a sphygmomanometer, capable of determining? Only systolic pressure.

What would you expect if a sphygmomanometer cuff designed to be used on a small child’s arm was used on an adult’s arm?

What would you expect if a sphygmomanometer cuff designed to be used on a small child’s arm was used on an adult’s arm? Measured systolic and diastolic pressures would both be higher than the true pressures. Measured systolic and diastolic pressures would both be lower than the true pressures.

How is the systolic pressure determined by auscultation by pulse detection?

At some point the person listening with the stethoscope will begin to hear sounds with each heartbeat.This point marks the systolic pressure. The sounds are called Korotkoff sounds. As the pressure is lowered further, the character of the Korotkoff sounds should change.

How do the finger pulse amplitude and systolic pressure change when the volunteer raises the arm above the head why?

The finger pulse amplitude decreases dramatically when the arm is held above the head. The systolic pressure will be harder to detect, and will be much lower than the blood pressure measurement with the hand at heart level.

What is korotkoff sound and what does it indicate?

At some point the person listening with the stethoscope will begin to hear sounds with each heartbeat.This point marks the systolic pressure. The sounds are called Korotkoff sounds. As the pressure is lowered further, the character of the Korotkoff sounds should change.

Which explanation best describes what happened to the finger pulse amplitude when the arm is held above the head in terms of the estimated systolic pressure?

Korotkoff sounds are generated when a blood pressure cuff changes the flow of blood through the artery. These sounds are heard through either a stethoscope or a doppler that is placed distal to the blood pressure cuff.

What physiological factor limits the speed at which you can accurately detect the blood pressure?

The finger pulse amplitude decreases dramatically when the arm is held above the head. The systolic pressure will be harder to detect, and will be much lower than the blood pressure measurement with the hand at heart level.

What would you expect if a pediatric sphygmomanometer cuff designed to be used on a small child’s arm was used on an adult’s arm 2.5 pts?

What would you expect if a sphygmomanometer cuff designed to be used on a small child’s arm was used on an adult’s arm? Measured systolic and diastolic pressures would both be higher than the true pressures. Measured systolic and diastolic pressures would both be lower than the true pressures.

Can you use a blood pressure cuff on a child?

Place the BP cuff against your child’s bare skin about 1 inch (2.5 cm) above his or her elbow. Wrap the cuff snugly around your child’s arm. The BP reading may not be correct if the cuff is too loose. If you are using a wrist cuff, wrap the cuff snugly around your child’s wrist.

What can you conclude about the effect of cuff size on measured blood pressure How can you explain this quizlet?

-If the cuff is too narrow, values will be too high. -If the cuff is too wide, values will be too low. –increases the heart rate and increases cardiac output

What is the purpose of inflating a sphygmomanometer around the arm?

Overview. To measure blood pressure, your doctor uses an instrument call a sphygmomanometer, which is more often referred to as a blood pressure cuff. The cuff is wrapped around your upper arm and inflated to stop the flow of blood in your artery

How does auscultation determine systolic pressure?

At some point the person listening with the stethoscope will begin to hear sounds with each heartbeat. This point marks the systolic pressure. The sounds are called Korotkoff sounds. As the pressure is lowered further, the character of the Korotkoff sounds should change.

Can you determine systolic pressure using palpation method?

Background: Most common method for measuring blood pressure is palpatory but only systolic pressure can be measured with this method.

How is pulse pressure determined?

The top number (systolic) minus the bottom number (diastolic) is the pulse pressure. For example, if the resting blood pressure is 120/80 millimeters of mercury (mm Hg), the pulse pressure is 40 which is considered a healthy pulse pressure.

How does Palpatory systolic pressure compare with auscultatory pressure?

[6] Palpatory methods for BP recording give only systolic BP values which are used to get approximates of SBPs, while the auscultatory method is used to get both SBP and DBP readings. It is universal for clinical measurement of BP.

What would you expect the measured systolic blood pressure to be with the arm raised above the head?

Arm position Dependency of the arm below heart level leads to an overestimation of systolic and diastolic pressures and raising the arm above heart level leads to underestimation. The magnitude of this error can be as great as 10 mm Hg for systolic and diastolic pressures.

What can you deduce about the direction of blood flow in the veins of the forearm quizlet?

What can you deduce about the direction of blood flow in veins in the forearm? You can determine that blood flows from the periphery toward the heart (with the venous valves limiting back flow).

What are some possible sources of error or variation in this technique of blood pressure measurement 2 pts enter your answer here?

Errors in blood pressure readings: The cuff is not of the proper size: if the cuff is too small the blood pressure readings may be artefactually high. If the cuff is too big, the readings may be artefactually low. The cuff is positioned too loosely: the blood pressure may be artefactually high.

How did the blood pressure in the leg while standing compare with that of laying down?

Results: The blood pressure tended to drop in the standing position compared with the sitting, supine and supine with crossed legs. Systolic and diastolic blood pressure was the highest in supine position when compared the other positions.

What do the two Korotkoff sounds that are recorded represent?

These are the systolic and diastolic blood pressures.

What indicates the first korotkoff sound?

Traditionally, the systolic blood pressure is taken to be the pressure at which the first Korotkoff sound is first heard and the diastolic blood pressure is the pressure at which the fourth Korotkoff sound is just barely audible.

What are the 5 Korotkoff sounds?

Korotkoff sounds (or K-Sounds) are the tapping sounds heard with a stethoscope as the cuff is gradually deflated. Traditionally, these sounds have been classified into five different phases (K-1, K-2, K-3, K-4, K-5) and are shown in the figure below.

What are Korotkoff sounds and what do they represent quizlet?

Terms in this set (12) what is the sounds heard when measuring blood pressure, and what causes them and why they occur. korotkoff sounds. they are due to blood turbulence occurring in the brachial artery under the stethoscope diaphragm

What would you expect the measured systolic blood pressure to be with the arm raised above the head 1 Pts?

Arm position Dependency of the arm below heart level leads to an overestimation of systolic and diastolic pressures and raising the arm above heart level leads to underestimation. The magnitude of this error can be as great as 10 mm Hg for systolic and diastolic pressures.

How did the blood pressure in the leg compare with that in the volunteer’s arm?

Supine systolic blood pressure in the leg was higher than in the arm (132xb123 mm Hg vs. 157xb126 mm Hg, arm vs. leg, respectively; px26lt;0.001). However, the diastolic blood pressures in the arm and leg were similar (77xb112 mm Hg vs.
