《灵枢·热病篇》曰∶热病三日，而气口静、人迎躁者，取之诸阳，五十九刺，以泻其热而出其汗，实
其阴以补其不足。身热甚，阴阳皆静者，勿刺也；其可刺者，急取之，不汗出则泄。所谓勿刺者，有死征也。
两手之脉名气口，主五脏之阴，颈旁动脉名人迎，主六腑之阳，义详十二经络篇。热病三日，气口静而人
迎躁者，阳热之邪盛于阳经也。盖人迎为阳明之脉，阳明行气于三阳，故当治诸阳经，以泻其热而出其汗，再
实其阴气，以补其不足。如身热甚，而气口、人迎之脉皆静者，脉证不合，本元气败，不能与邪争，故脉反静，
为死之征，不可妄治也。如其可以治者，急取之，若不汗出，则通腑以泄之可也。五十九刺者，经穴针法，
详针灸篇，不录。
热病七八日，脉口动喘而短者，急刺之，汗且自出，浅刺手大指间。
脉口即气口，又名寸口，动喘而短者，短为肺脉，邪入手太阴肺经，故刺手大指间肺经之井穴。脉口动喘，
其人迎亦必躁盛可知，热病七八日之久，故当急刺也。
热病七八日，脉微小，病者溲血，口中干，一日半而死，脉代者，一日死。
脉微小及代，皆邪热深陷而元气脱，故溲血口干，而死之速也。
热病已得汗出，而脉尚躁，喘且复热，勿刺肤，喘甚者死。
此即精却而邪胜者也，故死。
热病七八日，脉不躁，躁不散数，后三日中有汗。三日不汗，四日死。未曾汗出者，勿腠刺之。
热病七八日而脉不躁，邪气深沉之象，或躁而不散数，其元气尚未败，三日中或得汗解。如三日不汗，其
元气败而邪更深，四日必死矣，凡此等日久未曾汗出者，多是死证，勿妄治也。
《灵枢·热病篇》说：患热病三天，如果气口（手腕桡动脉内侧，反映五脏阴气）脉象平静，而人迎（颈部颈动脉外侧，反映六腑阳气）脉象躁动，应当针刺各阳经穴位，采用五十九穴刺法，以泻除热邪并促使出汗，同时充实阴液以补充其不足。如果身体发热严重，但气口和人迎的脉象都平静，则不要针刺；对于可以治疗的病例，应紧急针刺，若不能通过发汗解除，则通过通泄大便来祛除病邪。所谓“不要针刺”，是因为出现了死亡的征兆。
两手的气口脉主管五脏的阴气，颈部的人迎脉主管六腑的阳气，详细道理见十二经络篇。热病三天，气口脉静而人迎脉躁，说明阳热之邪盛于阳经。因为人迎是阳明胃经的脉，阳明经将气运行于三阳经，所以应当治疗各阳经，以泻除热邪并促使出汗，再充实阴气以弥补不足。如果身体发热严重，而气口、人迎的脉象都平静，这是脉象与证候不符，根本元气败坏，无法与邪气抗争，所以脉象反而平静，这是死亡的征兆，不可胡乱治疗。如果是可以治疗的，应紧急针刺，如果不发汗，则可以通过通腑泄下来治疗。五十九刺是经穴针法，详见针灸篇，此处不录。
热病七八天，脉口（即气口/寸口）跳动急促且呼吸短促，应紧急针刺，汗将会自然流出，浅刺手大指间的穴位。
脉口就是气口，又名寸口，跳动急促且呼吸短促，短脉是肺脉的特征，说明邪气侵入手太阴肺经，所以针刺手大指间肺经的井穴。脉口跳动急促，其人迎脉也必然躁动旺盛，热病已经持续七八天，所以应当紧急针刺。
热病七八天，脉象微小，患者尿血，口中干燥，一天半后死亡；脉象出现代脉（间歇脉），一天后死亡。
脉象微小和代脉，都是邪热深陷而元气脱失的表现，所以出现尿血口干，导致迅速死亡。
热病已经出汗，但脉象仍然躁动，气喘并且再次发热，不要针刺皮肤（体表），气喘严重的会死亡。
这是精气衰退而邪气胜出的情况，所以死亡。
热病七八天，脉象不躁动，或者躁动但不散乱快速，之后三天内会有汗出。如果三天没有汗出，第四天死亡。从未出过汗的，不要针刺腠理（皮肤毛孔）。
热病七八天而脉象不躁动，是邪气深沉的表现；或者躁动但不散乱快速，说明元气尚未败坏，三天内可能通过出汗痊愈。如果三天没有汗出，说明元气败坏而邪气更深，第四天必定死亡。凡是这种日久未曾出汗的，多是死证，不要胡乱治疗。
The *Ling Shu: Re Bing Pian* (Spiritual Pivot: Chapter on Heat Diseases) states: After three days of suffering from a heat disease, if the Qi Kou (Radial Artery at the wrist, reflecting Yin of the Zang organs) pulse is calm while the Ying Yang (Carotid Artery at the neck, reflecting Yang of the Fu organs) pulse is restless, one should puncture the various Yang meridians and apply the "Fifty-Nine Acupoints Needling" technique to drain the heat and induce sweating, thereby solidifying the Yin to replenish deficiencies. If the body heat is severe but both the Yin-Yang (Qi Kou and Ying Yang) pulses are calm, do not needle; for cases that can be treated, urgent needling is required, and if sweating does not occur, purgation should be used. The instruction "do not needle" refers to the presence of death omens.
The Qi Kou pulse of both hands governs the Yin of the Five Zang organs, while the Ying Yang pulse in the neck governs the Yang of the Six Fu organs; detailed explanations are found in the chapter on the Twelve Meridians. In heat disease lasting three days, a calm Qi Kou and restless Ying Yang indicate that Yang-heat pathogenic factors are abundant in the Yang meridians. Since Ying Yang belongs to the Stomach Meridian of Foot-Yangming, which circulates Qi among the Three Yang meridians, treatment should focus on the various Yang meridians to drain heat and induce sweating, followed by nourishing Yin Qi to address insufficiency. If body heat is severe yet both Qi Kou and Ying Yang pulses are calm, this represents a mismatch between pulse and symptoms, indicating the collapse of primordial Yuan Qi, which fails to contend with pathogens, resulting in a paradoxically calm pulse—a sign of death—thus prohibiting reckless treatment. For treatable cases, urgent needling is necessary; if sweating fails to occur, clearing the bowels via purgation is appropriate. The "Fifty-Nine Needling" refers to specific acupoint techniques detailed in the acupuncture chapters and is not repeated here.
After seven or eight days of heat disease, if the Mai Kou (Pulse Gate, synonymous with Qi Kou/Cun Kou) shows rapid movement accompanied by panting and shortness of breath, urgent needling is indicated; sweat will likely emerge spontaneously, and shallow needling should be applied to the space between the thumb and index finger.
Mai Kou is another name for Qi Kou or Cun Kou. Rapid movement with panting and shortness of breath indicates a Short pulse characteristic of the Lung; this signifies that pathogens have entered the Hand-Taiyin Lung Meridian, hence needling the Jing-Well acupoint of the Lung meridian located between the thumb and index finger. Given that the Mai Kou is rapid and the Ying Yang pulse is undoubtedly also restless after seven or eight days of heat disease, urgent needling is warranted.
After seven or eight days of heat disease, if the pulse is minute and faint, the patient experiences hematuria (blood in urine) and dry mouth, death occurs within half a day; if the pulse presents as Dai (Intermittent Pulse), death occurs within one day.
Both minute/faint and Dai pulses indicate deep entrapment of pathogenic heat and depletion of Yuan Qi, leading to rapid death manifested by hematuria and dry mouth.
If, after sweating has occurred in heat disease, the pulse remains restless, accompanied by panting and recurrent fever, skin needling should be avoided; severe panting indicates death.
This condition reflects the retreat of essence and the dominance of pathogens, leading to death.
In heat disease lasting seven or eight days, if the pulse is not restless, or if it is restless but not scattered and rapid, sweat may appear within the following three days. If no sweat occurs after three days, death ensues on the fourth day. For patients who have never sweated, do not needle the Cou Li (skin pores).
A non-restless pulse after seven or eight days of heat disease suggests deep-seated pathogens; if the pulse is restless but not scattered/rapid, Yuan Qi remains intact, allowing for potential resolution through sweating within three days. However, if no sweat occurs after three days, Yuan Qi has collapsed while pathogens deepen, guaranteeing death on the fourth day. Generally, prolonged heat diseases without sweating are often fatal conditions, warranting against reckless treatment.
