Examples of pulse in the following topics:
-
- Pulse varies with age; a newborn or infant can have a heart rate of about 130-150 beats per minute.
- The heart rate may be greater or lesser than the pulse rate depending upon physiologic demand.
- Radial pulse is commonly measured using three fingers, the finger closest to the heart is used to occlude the pulse pressure, the middle finger is used get a crude estimate of the blood pressure, and the finger most distal to the heart is used to nullify the effect of the ulnar pulse as the two arteries are connected via the palmar arches.
- Where more accurate or longer term measurements are required pulse rate, pulse deficits, and much more physiologic data are readily and simplistically visualized by the use of one or more arterial catheters connected to a transducer and oscilloscope.
- Measurement of the pulse can occur at several locations, including the radial artery shown here.
-
- Checking circulation involves measurement of blood pressure and pulse through a variety of invasive and noninvasive methods.
- Whilst a simplistic measurement of pulse rate is achievable by anyone trained medical staff are capable of much more accurate measurements.
- Radial pulse is commonly measured using three fingers, the finger closest to the heart is used to occlude the pulse pressure, the middle finger is used get a crude estimate of the blood pressure, and the finger most distal to the heart is used to nullify the effect of the ulnar pulse as the two arteries are connected via the palmar arches.
- Where more accurate or longer term measurements are required pulse rate, pulse deficits, and much more physiologic data are readily and simplistically visualized by the use of one or more arterial catheters connected to a transducer and oscilloscope.
- The rate of the pulse is observed and measured by tactile or visual means on the outside of an artery and is recorded as beats per minute or BPM.
-
- These properties allow the arterial wall to distend when pressure increases, resulting in a pulse that can be detected by touch.
- The pulse is the most straightforward way of measuring the heart rate, but it can be a crude and inaccurate measurement when cardiac output is low.
- In these cases (as happens in some arrhythmias), there is little pressure change and no corresponding change in pulse, and the heart rate may be considerably higher than the measured pulse.
-
- This leads to a rapid, weak pulse due to decreased blood flow combined with tachycardia, cool, clammy skin due to vasoconstriction, and stimulation of vasoconstriction.
- The symptoms of cardiogenic shock are similar to those of hypovolemic shock, with a weak pulse.
- With anaphylaxis, hives may present on the skin, as well as localised edema, especially around the face, weak, and rapid pulse.
-
- If a person still has a pulse, but is not breathing (respiratory arrest), artificial respirations may be more appropriate, but due to the difficulty people have in accurately assessing the presence or absence of a pulse, CPR guidelines recommend that lay persons should not be instructed to check the pulse, while giving health care professionals the option to check a pulse.
-
- Blood flow is a pulse wave that moves out from the aorta, through the arterial branches, and is reflected back to the heart.
-
- This pressure variation within the artery produces the observable pulse that reflects heart activity.
-
- The MRI machine emits an RF (radio frequency) pulse that specifically binds only to hydrogen.
- The pulse makes the protons in that area absorb the energy needed to make them spin in a different direction.
- The RF pulse makes the one or two extra unmatched protons per million spin at a specific frequency, in a specific direction.
-
- Laser tattoo removal usually refers to the non-invasive removal of tattoo pigments using Q-switched (pulsed) lasers.
-
- Blood pressure and pulse, or the vital signs, are measured as indicators of several aspects of cardiovascular health.
