brachial pulse

pulse

 [ pul] 2. the beat of the heart as felt through the walls of a peripheral artery, such as that felt in the radial artery at the wrist. Other sites for pulse measurement include the side of the neck (carotid artery), the antecubital fossa (brachial artery), the temple (temporal artery), the anterior side of the hip bone (femoral artery), the back of the knee (popliteal artery), and the instep (dorsalis pedis artery).

What is felt is not the blood pulsing through the arteries (as is commonly supposed) but a shock wave that travels along the walls of the arteries as the heart contracts. This shock wave is generated by the pounding of the blood as it is ejected from the heart under pressure. It is analogous to the hammering sound heard in steam pipes as the steam is forced into the pipes under pressure. A pulse in the veins is too weak to be felt, although sometimes it is measured by sphygmographphlebogram

The pulse is usually felt just inside the wrist below the thumb by placing two or three fingers lightly upon the radial artery. The examiner’s thumb is never used to take a pulse because its own pulse is likely to be confused with that of the patient. Pressure should be light; if the artery is pressed too hard, the pulse will disappear entirely. The number of beats felt in exactly 1 minute is the pulse rate.

In taking a pulse, the rate, rhythm, and strength or amplitude of the pulse are noted. The average rate in an adult is between 60 and 100 beats per minute. The rhythm is checked for possible irregularities, which may be an indication of the general condition of the heart and the circulatory system.

The amplitude of a pulse can range from totally impalpable to bounding and full; however, such terms are vague and subject to misinterpretation. To provide a more standardized description of pulse amplitude some agencies and hospitals use a scale that provides a more objective evaluation and reporting of the force of a pulse. On such a scale zero would mean that the pulse cannot be felt; +1 would indicate a thready, weak pulse that is difficult to palpate, fades in and out, and is easily obliterated with slight pressure; +2 would be a pulse that requires light palpation but once located would be stronger than a +1; +3 would be considered normal; and a +4 pulse would be one that is strong, bounding, easily palpated, and perhaps hyperactive, and could indicate a pathological condition such as aortic regurgitation.

If a pulse is noted to be weaker during inhalation and stronger during exhalation (pulsus paradoxus), this could indicate either greater reduction in the flow of blood to the left ventricle than is normal, as in constrictive pericarditisasthma emphysema.

An instrument for registering the movements, form, and force of the arterial pulse is called a sphygmograph Pulses palpated during appraisal of the arterial system. the beat of the heart as feel through the walls of a peripheral artery, such as that felt in the radial artery at the wrist. other sites for pulse measurement include the side of the neck ( carotid artery ), the antecubital pit ( brachial artery ), the temple ( temporal artery ), the front tooth side of the hip bone ( femoral artery ), the binding of the stifle ( popliteal artery ), and the instep ( dorsalis pedis artery ) .What is felt is not the blood pulsing through the arteries ( as is normally supposed ) but a shock wave that travels along the walls of the arteries as the heart contracts. This electric shock wave is generated by the pounding of the rake as it is ejected from the kernel under coerce. It is analogous to the hammering sound hear in steam pipes as the steam is forced into the pipes under coerce. A pulse in the veins is excessively unaccented to be felt, although sometimes it is measured by ( see below ) ; the tracing obtained is called aThe pulse is normally felt just inside the wrist below the ovolo by placing two or three fingers lightly upon the radial artery. The examiner ‘s ovolo is never used to take a pulse because its own pulse is likely to be confused with that of the affected role. pressure should be light ; if the artery is pressed besides hard, the pulse will disappear entirely. The count of beats felt in precisely 1 moment is the pulse rate.In taking a pulse, the rate, rhythm method of birth control, and forte or amplitude of the pulsate are noted. The average pace in an adult is between 60 and 100 beats per minute. The cycle is checked for potential irregularities, which may be an indication of the general condition of the kernel and the circulative system.The amplitude of a pulsation can range from wholly impalpable to bounding and full ; however, such terms are obscure and subject to misinterpretation. To provide a more standardize description of pulsation amplitude some agencies and hospitals use a scale that provides a more objective evaluation and report of the force of a pulse. On such a scale zero would mean that the pulsate can not be felt ; +1 would indicate a ropy, unaccented pulse that is unmanageable to palpate, fades in and out, and is well obliterated with rebuff pressure ; +2 would be a pulse that requires alight palpation but once located would be stronger than a +1 ; +3 would be considered convention ; and a +4 pulse would be one that is strong, bound, well palpated, and possibly hyperactive, and could indicate a pathological condition such as aortal regurgitation.If a pulse is noted to be weaker during inhalation and stronger during halitus ( ), this could indicate either greater reduction in the flow of blood to the bequeath ventricle than is normal, as in constrictiveor pericardial

effusion

, or a grossly exaggerated inspiratory maneuver, as in tracheal obstruction, , orAn instrumental role for registering the movements, form, and force of the arterial pulse is called a. The sphygmographic trace ( or pulse tracing ) consists of a curve having a sudden emanation ( primary natural elevation ) followed by a sudden fall, after which there is a gradual origin marked by a number of junior-grade elevations.
