脉象弦而大，弦脉意味着阳气衰减，大脉意味着中空如芤。阳气衰减则生寒，阴血空虚则成虚。寒与虚相互搏结，这种脉象称为“革”脉。妇女出现此脉，会导致小产或崩漏下血；男子出现此脉，会导致失血或遗精滑精。
脉象弦而大，弦脉表示阳气不足因而产生寒象，大脉（芤）表示阴血不充因而产生虚象。寒与虚相互搏结，这种脉象称为“革”脉。“革”脉的形态如同鼓皮，外表坚实而内部空虚。
卫气统摄于肺，营血藏纳于肝。卫气衰弱则外部阳气减损，营血衰弱则内部阴血亏空。所谓“减”，是卫气衰弱导致的气寒；所谓“芤”，是营血衰弱导致的血虚。气血既虚又寒，脉象如同皮革般外硬内软。妇女见此脉象，则发生小产和漏下出血；男子见此脉象，则发生亡血和失精。这是因为中气颓败，不能交济水火。肾水下寒而心火上炎，水木之气下陷则内部形成虚寒，火金之气上逆则外部呈现弦象。金水不能闭藏，而木火易于疏泄，所以导致胎堕经漏、血脱精遗。（所谓的“漏下”，是指非月经期间血液下行，崩决之势如同堤防崩溃水流暴泻，淋漓之状如同铜壶滴漏水流续下。）
寸口脉微而涩。微脉代表卫气衰弱，涩脉代表营气不足。卫气衰弱则面色发黄，营气不足则面色发青。营气为根，卫气为叶，营卫俱微则根叶枯槁，从而出现寒战、咳嗽气逆、唾吐腥臭之物及涎沫等症状。
寸口脉微而涩。微脉代表卫气的衰弱，涩脉代表营气的不足。卫气生于胃，卫气衰弱则戊土（胃）虚弱而面色发黄；营血藏于肝，营血不足则乙木（肝）枯槁而面色发青。营是卫的根基，卫是营的枝叶。营卫俱微则根叶枯槁，出现寒战、咳嗽气逆、唾吐腥臭涎沫等各种证候，这是因为脾土败坏不能生养肺金所致。
寸口脉微而缓。微脉代表卫气疏泄，疏泄则皮肤腠理空豁；缓脉代表胃气充实，充实则能消化谷物并化生水液。谷物进入胃中，脉道得以通行；水液进入经脉，血液方能生成。若营血独盛，则皮肤必然疏泄，三焦经络断绝，这种情况称为“血崩”。
寸口脉微而缓。微脉代表卫气的疏泄，疏泄则皮肤空豁而不致密；缓脉代表胃气的充实，充实则能消化谷物并化生水液。（《灵枢·五津液别》中提到：体内有热则胃中消谷，肠胃充盈扩张，所以脉象表现为缓。）血脉是由水谷精气所化生的。谷物进入胃中，布散于体表，脉道得以通行；水液进入经脉，变化为赤色，血液才真正形成。谷物消化、水液转化后进入血脉，营气便形成了。肺主气，气盛则清凉收敛；肝主血，血盛则温暖发散。营与卫两种气机调和，则营气不会单独偏盛；若营血独盛，则血液更加温散而气机不清敛，汗孔开泄，因此皮肤必然疏泄。一旦疏泄，三焦经络中的血液就会全部化为汗液泄出于皮毛，所以称为“血崩”。这就是所说的“夺汗者无血，夺血者无汗”，因为汗液就是血液酝酿而成的。
The pulse is wiry (Xian) and large. Wiry indicates a decline [in yang], and large indicates a hollow [like the Kou pulse]. A decline implies cold, and hollow implies deficiency. The interplay of cold and deficiency is named "Ge" (Leather). In women, this leads to miscarriage or metrorrhagia; in men, it leads to blood loss or seminal emission.
The pulse is wiry and large. Wiry indicates insufficient yang qi, resulting in cold; large [hollow] indicates insufficient yin blood, resulting in deficiency. The interplay of cold and deficiency is named "Ge". The "Ge" pulse feels like the skin of a drum: firm on the outside and empty on the inside.
Wei Qi (Defensive Qi) is governed by the Lung, and Ying Blood (Nutritive Blood) is stored in the Liver. When Wei Qi declines, the exterior becomes deficient; when Ying Blood declines, the interior becomes hollow. "Decline" refers to cold qi due to Wei Qi deficiency; "Hollow" refers to blood deficiency due to Ying Blood deficiency. With both Qi and Blood being deficient and cold, the pulse resembles leather. Women presenting this pulse suffer from miscarriage and metrorrhagia; men presenting this pulse suffer from blood loss and seminal emission. This occurs because the Middle Qi has collapsed and cannot harmonize Water and Fire. Kidney Water sinks with cold while Heart Fire rises with heat; Water and Wood sink downward, causing internal deficiency-cold; Fire and Metal reverse upward, causing external wiriness. Metal and Water fail to store, while Wood and Fire tend to leak, thus leading to fetal abortion and menstrual leakage, blood depletion and sperm loss. (Metrorrhagia refers to bleeding outside the menstrual period; the sudden gushing is like a breached dike flooding violently, while the continuous dripping is like water leaking from a clepsydra.)
At the Cun Kou (Radial Artery), the pulse is faint (Wei) and choppy (Se). Faint indicates the decline of Wei Qi; choppy indicates the insufficiency of Ying Qi. Decline of Wei Qi manifests as a sallow complexion; insufficiency of Ying Qi manifests as a bluish complexion. Ying is the root, and Wei is the leaf. If both Ying and Wei are minute, the roots and leaves wither, leading to chills, coughing with counterflow qi, spitting of foul-smelling saliva, and froth.
At the Cun Kou, the pulse is faint and choppy. Faint indicates the decline of Wei Qi; choppy indicates the insufficiency of Ying Qi. Wei Qi originates in the Stomach; its decline causes Wu Earth (Stomach) to be deficient, manifesting as a sallow complexion. Ying Blood is stored in the Liver; its insufficiency causes Yi Wood (Liver) to wither, manifesting as a bluish complexion. Ying is the root of Wei, and Wei is the leaf of Ying. If both Ying and Wei are minute, the roots and leaves wither, giving rise to chills, coughing with counterflow qi, and spitting of foul saliva and froth. These symptoms arise because Spleen Earth fails to generate Lung Metal.
At the Cun Kou, the pulse is faint and slow. Faint indicates the dispersion of Wei Qi, making the skin pores open and loose; slow indicates the fullness of Stomach Qi, which digests grain and transforms it into fluids. Grain entering the Stomach allows the pulse channels to flow; fluids entering the meridians allow blood to form. If Ying Blood becomes excessive, the skin must become loose. If the San Jiao (Triple Burner) meridians are severed, it is called "Blood Collapse" (Menorrhagia/Hemorrhage).
At the Cun Kou, the pulse is faint and slow. Faint indicates the dispersion of Wei Qi, making the skin loose and not dense; slow indicates the fullness of Stomach Qi, which digests grain and transforms it into fluids. (In *Ling Shu: Five Fluids*, it is stated: Heat in the stomach digests grain, filling and expanding the intestines and stomach, hence the pulse appears slow.) Blood vessels are transformed from the essence of water and grain. Grain enters the Stomach, spreads outward, and the pulse channels flow; water enters the meridians, changes to red, and blood is formed. After grain is digested and water is transformed, entering the blood vessels, Ying Qi is established. The Lung governs Qi; when Qi is abundant, it is cool and astringent. The Liver governs Blood; when Blood is abundant, it is warm and dispersing. When Ying and Wei Qi are harmonious, Ying does not dominate alone. If Ying Blood dominates alone, the blood becomes warmer and more dispersing, while Qi fails to be cool and astringent. The sweat pores open and leak, so the skin becomes loose. Once loose, the blood in the San Jiao and meridians is entirely transformed into sweat and excreted through the hair follicles, hence it is called "Blood Collapse." This is what is meant by "Do not bleed those who have lost sweat, do not sweat those who have lost blood," for sweat is the fermented product of blood.
