peripheral vascular sign

The peripheral vascular sign is an auxiliary examination method for checking whether the blood vessel is normal. Peripheral vascular signs refer to peripheral vascular signs that are clinically common for changes in pulsation or waveforms found when examining surrounding blood vessels under certain disease conditions. Mainly seen in aortic valve insufficiency, hyperthyroidism, severe anemia and other diseases with increased pulse pressure. Through this examination, the lesion and the corresponding symptoms can be judged. Basic Information Specialist Category: Cardiovascular Examination Category: Other Examinations Applicable gender: whether men and women apply fasting: not fasting Tips: Maintain a normal diet and schedule. Normal value Normally, two sounds corresponding to the first heart sound and the second heart sound can be heard in the carotid artery or the subclavian artery at normal time and are not heard in other arteries. The normal pulse wave has a repeatedly rising pulse wave during its falling period but is lower than the first wave and cannot be touched. Clinical significance Abnormal results are mainly seen in aortic valve insufficiency, hyperthyroidism, severe anemia and other diseases with increased pulse pressure. The performance is as follows: 1. Capillary pulse dysfunction (capillarypulsationsyndrome) with a finger gently press the end of the patient's finger bed or gently press the lip mucosa with a clean glass sheet. See the alternating rhythmic microvascular pulsation phenomenon called red and white called capillary pulsation. 2. Waterhammerpulse The water impulse is also called the vein, the fast pulse or the Corrigan vein. During the examination, the patient's arm is raised above the head and the palm of the hand is gripped. The patient's pulse suddenly rises and falls, and the force is rapid and powerful, just like the water wave rushes over, so it is called the water pulse. 3. Pistolshotsound, in the pathological situation, the chest of the stethoscope is placed lightly on the patient's radial or femoral artery. The sound of "Ta-Ta" can be heard as the gunshot sound. 4. Duroziez double tone, with the chest piece of the stethoscope placed on the root of the patient's femoral artery to hear the double sound of the contraction sound and echo that occurs with the contraction of the heart is called Duroziez double tone. 5. Carotid pulsation and often accompanied by a little head movement. 6. alternating pulses (pulsusalternans), alternating pulses for the normal rhythm of the species and the alternating appearance of the strong and weak pulse is the manifestation of myocardial damage. 7. Dicrotic pulse (dicroticpulse), in some pathological cases, this wave is increased and can be called to be called the sacral pulse, that is, a systolic phase can touch two pulse beats. 8. Paradoxicalpulse, the phenomenon that the pulse is obviously weakened or even disappeared during inhalation is called the odd pulse. The insignificant odd pulse can only be found when the blood pressure is auscultated, that is, the original heard pulse sound weakens or disappears when inhaling. Or systolic blood pressure is reduced by 1.33 kPa or more during the inspiratory phase compared with the expiratory phase. 9. Boundingpulse, Hongmai refers to a pulse with a normal shape and a large amplitude. When the blood vessels are palpated, the pulse is strong and large. 10. Small pulse (small pulse), fine veins refer to normal shape and small amplitude pulse and Hong pulse. On the contrary, when the palpation is weak, the pulse is also called threadyPulse. The person who needs to be examined is routinely examined at the time of group examination, and the vascular abnormality is present. Precautions Forbidden before examination: Maintain a normal diet and schedule. Requirements for examination: The patient actively cooperates with the doctor during the examination, and should not be overly stressed during the examination, so as not to affect the result. Inspection process The patient is placed in the supine position, and the doctor performs an examination under appropriate light to determine the corresponding symptoms of the patient by observing the shape, color, and distribution of the blood vessels. The contents of the examination include: capillary pulsation, water pulse, gunshot sound, Duroziez double tone, carotid pulsation, alternating pulse, etc. The specific methods of each examination are different, so the doctor should flexibly select the specific examination according to the contents of the examination. method. Not suitable for the crowd Inappropriate people: severe blood vessels and heart failure.
