Exercise 18-5 Clinical Applications Knowledge of blood ves t for many differe cal applications. Here w e r e pule pale and 20 locating veins for hende s North ore not actually going to be wicking each other with medles upong to be finding the w i ng needles in the MATERIALS Procedure 1 Pulse Palpation Ach Pule palpation is the so n g the fingertips to feel pule points locations where the artery is superficialech that the artery phations with each w e can be fit. It is formed to the rate them, and regularity of the heartbeat, and to assess the arterial circulation to different parts of the band The len s commonly used are the found at the radial, wahachuld val l a ndais shown in Figure 15.24 When pulses are palpated, they are graded according to a standard sale. This allows healthcare professionals to communicate about a patient unambiguously and to a s the progress or deterioration of a patient's condition. The scale utilizes the following for grades Grade 44. The pulse is absent. Grade 1/4: The pulse is barely or only lightly palpable. I Grade 2/4: The pulse is normal. Grade 14: The pulse is abnormally strong. Grade 4/4: The pulse is bounding and visible through the skin. Notice that this scale has no negative numbers or decimal numbers you would not use - 1/4 or 2.5/4). In a healthy person most pulses are grade 2/4 (readas, two out of four"), although occasionally a pulse is weak or absent. This is simply normal anatomical variation and does not signify pathology. Students often mistakenly grade any strong pulse as 4/4. If a pulse were truly 4/4, however, this would be a sign of extremely high blood pressure in that artery and would possibly be - Temporal a medical emergency. Most strong, healthy pulses are graded as 2/4. Carotid 18 Please note before you begin that you should never assess both of your lab partner's carotid pulses at the same time. Doing so might initiate the baroreceptor reflex (BEHR-che-sep-ter), in which the parasympathetic nervous system triggers a reflexive and often dramatic drop in blood pressure and heart rate. This could cause your lab Brachia partner to momentarily lose consciousness. When you have completed the procedure, answer Check Your Understanding question 6 (p. 504). Femoral 1 Wash your hands prior to palpating your lab partner's pulses. 2 On a model or diagram, locate the artery you are palpating. 3 Lightly place your index finger and middle finger over the artery. You may increase the pressure slightly, but be careful not to press too hard, because you could cut off Pop blood flow through the artery and also could mistake the pulse in your fingertips for your partner's pulse. If you are unsure if the pulse is yours or your partner's feel the lab table. If the lab table "has a pulse,"you are feeling the pulse in your own fingertips. 4 Palpate only one side (right or left) at a time, especially in the carotid artery. -Dorsals 5 Grade your partner's pulses according to the 0/4 to 4/4 scale, and record the results in Table 18.3.
