慎柔认为：虚损病出现洪大脉，重按时中间尚有一条（指脉管中仍有实质搏动感的线条）的，可以治疗；如果脉象空散，没有这一条线，即使暂时痊愈，最终也必然死亡。这里所说的“一条”，就是脉中的脊骨（指脉气之根本），并非指下感觉另外多出一条脉。我曾经说：喘证的脉象，多半是满指虚浮跳动，不见正常的脉形，有根气的可以治疗，无根气的即死。所谓“根”，就是脉的脊骨。元廉夫说：散脉中若有一线，是肝邪盛而脾败的征象。这里所说的一线，乃是弦劲挺然于指下，死硬而没有生气，这是血死于体内，气无所归附。前人曾说：阳气不到的地方，脉就会呈现弦象。这种弦象见于里证，足以证明五脏真阳已经耗竭。慎柔也说：劳损证出现寒热交替并伴有腹泻，脉数而重按洪缓，贴骨指下如丝线般细微，这是不可救治的。王汉皋说：痰饮凝结，脉象多在弦洪之中，夹杂一条细线，隐伏于指下但有力。这条细滑脉见于中取和沉取之间，是胃阳郁结而不能宣通的表现。凡是脉中有细线，松弛而急促的，都是内有热邪而有实物制约，或者是热痰内结，或者是热血内瘀。这三种情况，形态各不相同，吉凶相差甚远，应当详细辨别。若是热血内瘀，要防止形成内痈。其症状为烦渴，夜间加重，隐隐有肿胀疼痛之处，兼有小便赤涩。
《脉简补义》论述脉象如同参量线（测量用的尺/线），认为是痰病，以及将死时气尽血散的征象，论述得很详尽。近来读《仓公传》记载说：“切按其脉，得到肺阴气，其来势有多条路径，到达时却不一致，面色又克制脉色，所以知道他会十天后因尿血而死。”所谓得到肺阴气，是指得到肺的真脏脉。《内经》说：所谓的阴，就是指真脏脉。肺脉短涩而散，所以说它来势散乱。“数道”，就是像参量线一样多条并行。“至而不一”，就是真正的涩脉。因尿血而死，是气血不能相互维系的原因。这个病是由于从马上摔落僵在石头上导致肺受伤。张仲景《辨脉篇》说：“咳嗽气逆，脉象散的会死，这是因为形体受损。”我拙劣的注解认为形损就是肺体伤损，正与此意暗合。因为脏腑形体瘀败，真气不能荣养，所以脉象开散而不聚拢。由此推断，凡是喘咳病严重，以及一切痈疽、跌打损伤、失血等证候，见到这种脉象，如果兼见涩结且至而不一，就是短期之内必死。大概这种脉重按时，如果线条仍然攒聚在指下，是痰实；如果线条向两边开散，是气散。旧说八怪脉中，有所谓“如解索”的，就是此脉。
Shen Rou stated: In deficiency-consumption diseases, if the pulse is surging and large (Hongda), but upon deep pressure, there remains a single line (referring to the substantial core of the pulse) in the middle, it is treatable; if the pulse is empty and scattered with no such line, even if there is temporary relief, death is inevitable. The "single line" mentioned here refers to the "spine" (the root/foundation) of the pulse, not an additional vessel felt under the fingers. I have said: Pulses in asthma (Chuan) are mostly full-of-fingers, void, and moving, lacking a normal shape; if there is a root, it is treatable; if there is no root, it is fatal. The "root" is the spine of the pulse. Yuan Lianfu stated: If a scattered pulse (Sanmai) contains a single line, it is a sign of liver pathogenic factors and spleen failure. This "single line" is tense, firm, and stiff under the fingers, devoid of vitality, indicating blood stagnating internally and qi having no place to return. Predecessors stated: Where yang qi does not reach, the pulse becomes wiry (Xian). When this wiry quality appears in interior conditions, it confirms that the true yang of the five zang organs has already dissipated. Shen Rou also said: In labor-damage syndromes with alternating chills and fever accompanied by diarrhea, if the pulse is rapid, surging, and slow upon deep pressure, feeling like a fine thread against the bone, it is incurable. Wang Hangan stated: In phlegm-fluid retention, the pulse often presents as wiry and surging, interspersed with a fine line, hidden under the fingers yet forceful. This fine and slippery quality appearing at moderate and deep depths indicates stomach yang being constrained and unable to diffuse. Whenever a fine line in the pulse is loose yet rapid, it indicates internal heat restrained by tangible pathogens, either due to internal accumulation of hot-phlegm or internal stasis of hot-blood. These three types differ in form and prognosis, so they must be distinguished carefully. Internal stasis of hot-blood may develop into an internal abscess. Symptoms include irritability and thirst worsening at night, vague swelling and pain, and red, scanty urination.
Mai Jian Bu Yi discusses pulses resembling measuring lines, regarding them as signs of phlegm diseases and the dispersion of blood and exhaustion of qi near death, which is a detailed explanation. Recently, reading the Biography of Master Cang, it states: "Palpating the pulse, one obtains the yin qi of the lung; its arrival is multi-directional, yet inconsistent upon reaching; the complexion overcomes the pulse color, therefore it is known that death from hematuria will occur within ten days." Obtaining the lung's yin qi means obtaining the true zang pulse of the lung. The Nei Jing states: What is called 'yin' refers to the true zang pulse. The lung pulse is short, choppy, and scattered, hence described as arriving in a scattered manner. "Multi-directional" means multiple lines running parallel, like measuring lines. "Inconsistent upon reaching" signifies true choppy (Se) quality. Death from hematuria results from the failure of qi and blood to sustain each other. This disease originated from falling from a horse onto a stone, injuring the lung. Zhang Zhongjing's Bian Mai Pian states: "Coughing and rebellious qi with a scattered pulse indicate death, because the physical form is damaged." My humble annotation interprets "physical damage" as injury to the lung tissue, which coincides with this meaning. Because the organ's structure is瘀败 (stagnant and ruined), and true qi fails to nourish, the pulse scatters and fails to gather. From this, we can infer: in severe asthma and cough, as well as all cases of carbuncles, traumatic injuries, and hemorrhage, if this type of pulse is seen, especially when accompanied by choppy, knotted qualities and inconsistency upon arrival, death is imminent. Generally, if upon deep pressure the line gathers tightly under the fingers, it indicates phlegm excess; if the line scatters to both sides, it indicates qi dispersion. In the old theory of eight strange pulses, what is called "like untying a rope" (Ru Jie Suo) refers to this pulse.
