What are the different pulse points in the body?
We will review 9 common pulse points on the human body. As a nurse you will be assessing many of these pulse points regularly, while others you will only assess at certain times. These pulse sites include temporal, carotid, radial, apical, brachial, femoral, popliteal, dorsalis pedis, and posterior tibial.
How do you assess a pulse point?
When you assess a pulse point you will be assessing: 1 Rate: count the pulse rate for 30 seconds and multiply by 2 if the pulse rate is regular, OR 1 full minute if the pulse rate is irregular. ... 2 Strength: grade the strength of the pulse and check the pulse points bilaterally and compare them. ... 3 Rhythm: is the pulse regular or irregular
What is a pulse sequence diagram?
“A pulse sequence diagram is to an MRscientist as sheet music is to a musician.” Introduction A pulse sequence diagram (PSD)illustrates the sequence of events that occur during magnetic resonance imaging (MRI). It is a timing diagram showing the radio frequency (RF) pulses, gradients, and echoes.
What is the strength of the pulse?
The strength of the pulse is the force of blood felt at each heartbeat. It is determined by the amount of blood pushed out of the heart into the arteries with every heartbeat. The force will be at normal strength if the client has a normal pulse. Abnormal strengths of the pulse are:

What are the 5 pulse points?
The pulse is readily distinguished at the following locations: (1) at the point in the wrist where the radial artery approaches the surface; (2) at the side of the lower jaw where the external maxillary (facial) artery crosses it; (3) at the temple above and to the outer side of the eye, where the temporal artery is ...
How many pulse locations are there?
There are 9 common pulse points on the surface of the body. Namely, temporal pulse, carotid pulse, apical pulse, brachial pulse, radial pulse, femoral pulse, popliteal pulse, posterior tibial pulse, and dorsalis pedis pulse.
How do you read a pulse?
To check your pulse at your wrist, place two fingers between the bone and the tendon over your radial artery — which is located on the thumb side of your wrist. When you feel your pulse, count the number of beats in 15 seconds. Multiply this number by four to calculate your beats per minute.
Where are the pulse points in the head?
The facial pulse – as the facial artery passes over the angle of the mandible a pulse can be felt.
Where is the pulse measured?
For example, in the upper limb ? the pulse can be measured at the wrist, or in the lower limb? on the front of the foot. Let’s take a look at the pulse points in the head in a little more detail.
Why does blood pressure increase when you take your pulse?
Because it is elastic, this increase in pressure makes the vessel expand. It is these increases in blood pressure, called the systolic pressure, which can be felt when someone takes your pulse. This means someone can measure the rate at which your heart is beating by taking your pulse.
How to tell if you have a pulse?
In the head there are three pulse points (labelled above). They are: 1 The carotid pulse – along the anterior border of the sternocleidomastoid muscle, the common carotid artery can be located and pushed against the thyroid cartilage. 2 The facial pulse – as the facial artery passes over the angle of the mandible a pulse can be felt. See if you can find this one on yourself, it can sometimes be difficult to locate. 3 The temporal pulse – in front of the ear, the superficial temporal artery can be compressed against the temporal bone.
Can a clinician assess your heart rate?
As well as the heart rate, a clinician can also appreciate the rhythm of your heart – if it is beating regularly. Additionally they can even make a rudimentary assessment of the functionality of your heart – if the pulse is weak, the heart might not be pumping blood efficiently.
Where is the pulse point located in the head?
This artery comes off of the external carotid artery and is found in front of the tragus and above the zygomatic arch (cheekbone). This pulse point is assessed during the head-to-toe assessment of the head.
How long should a nurse count pulses?
As a nurse you will be assessing many of these pulse points regularly, while others you will only assess at certain times. Rate: count the pulse rate for 30 seconds and multiply by 2 if the pulse rate is regular, OR 1 full minute if the pulse rate is irregular. Always count the apical pulse for 1 full minute. ...
What is the most commonly used site for CPR?
Carotid. This site is most commonly used during CPR in an adult as a pulse check site. It is a major artery that supplies the neck, face, and brain. As noted above, palpate one side at a time to prevent triggering the vagus nerve, which will decrease the heart rate and circulation to the brain.
How to find EHL?
To find this artery, locate the EHL (extensor hallucis longus) tendon by having the patient extend the big toe. Then palpate down this tendon and when you come to end of it, go to the side of the tendon and you will find this pulse point.
What should your pulse be before Digoxin?
The pulse rate should be 60 bpm or greater in an adult before the administration of Digoxin. Always count the pulse rate for 1 full minute with your stethoscope at this location. The apical pulse is the point of maximal impulse and is found at the apex of the heart.
What is the brachial artery?
Brachial. This is a major artery in the upper arm that divides into the radial and ulnar artery. This site is used to measure blood pressure and as a pulse check site on an infant during CPR. To find this pulse point, extend the arm and have the palms facing upward.
What is a PSD in MRI?
A pulse sequence diagram ( PSD) illustra tes the sequence of events that occur during magnetic resonance imaging ( MRI ). It is a timing diagram showing the radio frequency ( RF) pulses, gradients, and echoes. Having a good knowledge of the PSD will help the reader follow complicated pulse sequences with more ease and understand the interplay among various scan parameters.
What happens when you apply a gradient to stationary spins?
For stationary spins, application of a gradient will make the spins go faster and faster and , as they go faster, they’ll get out of phase. With the negative gradient, the stationary spins will have a maximum phase difference at the end of the negative gradient.
Where are the pulse points on the body?
9 most commonly assessed pulse points on the body by nurses are: Temporal pulse – over the temple. Carotid pulse – at the side of the neck. Apical pulse – over the 5th intercostal space (ICS) at left mid-clavicular line. Brachial pulse – on the antecubital fossa (crook) of the arm.
How is the force of a pulse determined?
It is determined by the amount of blood pushed out of the heart into the arteries with every heartbeat. The force will be at normal strength if the client has a normal pulse. Abnormal strengths of the pulse are: A weak or feeble pulse indicates reduced cardiac output and requires immediate action.
What is the purpose of the carotid artery pulse site?
The carotid artery pulse site is used: to assess peripheral pulse characteristics. to assess the presence of pulse when a person collapses and during cardiopulmonary resuscitation (CPR) when other peripheral pulses are not palpable. Watch the video to see the anatomical landmark for carotid pulse.
Where is the carotid pulse located?
The anatomical location of the carotid pulse is along the medial edge of the sternocleidomastoid muscle in the neck (i.e., mid-line between earlobe and chin below the jawline.) Use index and middle fingertips to palpate carotid artery.
