言，审守其输，调其虚实。所谓柱骨之上者，盖天容穴也。人迎者，结喉两旁之脉动处也。乃取天容、人迎二
穴补之也。

〔《素》〕脾脉搏坚而长，其色黄，当病少气。（脉要精微论）一呼脉一动，一吸脉一动，曰少气。（平人气象论）
尺坚大，脉小甚，少气， 有加，立死。（全文见诊 谓尺内坚而脉反小，而少气 加也。）
《黄帝内经·素问》记载：三阳经之气断绝，三阴经之气微弱，这就称为少气。（出自《方盛衰论》篇）身体怯弱、气息短少的症状，是由于水道运行不畅，导致形体与正气消耗枯竭所致。（出自《示从容篇》篇）
说话声音低微，一整天才能说几句话，这是夺气（正气严重耗损）的表现。（全文内容见《诊生死》相关章节。）

一阳经发病时，会出现少气、容易咳嗽、容易腹泻的症状。（全文内容见《诊病传变》相关章节。）
第一种是火热所致。经文说：火邪郁结发作时，百姓患病表现为少气。又说：少阴君火复气时，会出现少气和骨痿。又说：少阳相火复气时，会出现少气和脉痿，治疗应当使用各种寒凉药物。
第二种是风湿所致。经文说：当太阳司天之年，四之气阶段，风湿二气交争，风化为雨，百姓患病表现为大热和少气。
关于针灸治疗少气，主要有三种方法：
第一种是补肺。经文说：肺脏主藏气，气不足则呼吸微弱、少气，应当补益其经络隧道，不要耗散其正气。又说：肺气虚则少气、不能深长呼吸，伴有耳聋、咽喉干燥，应当取手太阴肺经、足太阳膀胱经外侧以及足厥阴肝经内侧的出血点进行治疗。
第二种是补肾。经文说：出现少气，身体感觉寒冷战栗，说话时呼吸急促，骨骼酸痛、身体懈怠无力不能活动，应当补足少阴肾经。（“漯”字读音为“运合切”。）
第三种是补气海。经文说：膻中穴部位，是气的汇聚之所（气海），其输注穴位上部在脊柱上下，前部在人迎穴处。如果气海不足，就会气少不足以言语，应当仔细审视并守住这些输穴，调节其虚实。所谓“柱骨之上”，指的是天容穴。人迎穴则是喉结两侧脉搏跳动之处。因此选取天容、人迎两个穴位进行补法操作。
鱼际络脉颜色发青且短小的，是少气的表现。（全文内容见《阴阳》相关章节。）
《黄帝内经·素问》记载：脾脉搏动坚实而长，面色发黄，应当患有少气。（出自《脉要精微论》篇）一呼之间脉跳一次，一吸之间脉跳一次，这叫做少气。（出自《平人气象论》篇）
尺肤坚硬粗大，但脉象却非常细小，这是少气的表现；如果病情加重，会立即死亡。（全文内容见《诊谓尺内坚而脉反小，而少气加也》相关章节。）
Sha Qi (Shortness of Qi) refers to a condition where the Yuan Qi (Original Qi) is deficient, insufficient to support speech.
The *Huangdi Neijing Suwen* records: When the Qi of the Three Yang meridians is exhausted and the Qi of the Three Yin meridians is weak, this is termed Sha Qi (Shortness of Qi). (From the chapter "Fang Sheng Shuai Lun") A symptom of timidity and shortness of qi indicates that the water pathways are not flowing, leading to the consumption and exhaustion of both form and Zheng Qi (Upright Qi). (From the chapter "Shi Cong Rong Pian")
Speaking in a low voice, with only a few words spoken throughout the entire day, indicates Duo Qi (Severe Depletion of Qi). (Full text available in chapters related to diagnosing life and death.)
For the treatment of upper Jiao Sha Qi (Shortness of Qi), methods generally belong to formulas such as Sheng Mai San (Generate the Pulse Powder) and Du Shen Tang (Single Ginseng Decoction).
When disease originates from one Yang meridian, symptoms include Sha Qi (Shortness of Qi), frequent coughing, and frequent diarrhea. (Full text available in chapters related to the transmission of disease.)
Regarding Sha Qi (Shortness of Qi) caused by the Five Movements and Six Qi, there are two types:
First, due to Fire-Heat. The classic states: When Fire pathogen is constrained and erupts, the people suffer from Sha Qi (Shortness of Qi). It also states: When the Sha Yin (Lesser Yin) returns, there is Sha Qi (Shortness of Qi) and Gu Wei (Bone Atrophy). It further states: When the Shao Yang (Lesser Yang) returns, there is Sha Qi (Shortness of Qi) and Mai Wei (Vessel Atrophy); treatment should employ various cold-natured herbs.
Second, due to Wind-Dampness. The classic states: In years when Tai Yang governs the Heaven, during the fourth Qi period, Wind and Dampness contend, transforming into rain; the people suffer from severe heat and Sha Qi (Shortness of Qi).
Regarding acupuncture treatment for Sha Qi (Shortness of Qi), there are three approaches:
First, tonifying the Lung. The classic states: The Lung stores Qi; when Qi is insufficient, respiration becomes faint and there is Sha Qi (Shortness of Qi). One should tonify its meridian collaterals without dispersing its Qi. It also states: When Lung Qi is deficient, there is Sha Qi (Shortness of Qi), inability to take deep breaths, accompanied by deafness and dry throat. Treatment involves taking blood from the Hand Taiyin Lung Meridian, the lateral aspect of the Foot Taiyang Bladder Meridian, and the medial aspect of the Foot Jueyin Liver Meridian.
Second, tonifying the Kidney. The classic states: When there is Sha Qi (Shortness of Qi), the body feels cold and trembling, speech is accompanied by rapid inhalation, bones ache, and the body feels slack and weak, unable to move. One should tonify the Shaoyin Kidney Meridian. ("Luo" is pronounced 'yun he qie'.)
Third, tonifying the Qi Sea. The classic states: The Danzhong area is the Sea of Qi. Its transport points are located superiorly at the cervical vertebrae and anteriorly at the Renying point. If the Qi Sea is deficient, there is Sha Qi (Shortness of Qi) insufficient for speech. One must carefully observe and secure these transport points, regulating their excess or deficiency. The term "superior to the pillar bone" refers to the Tianrong acupoint. The Renying point is the location of pulse movement on both sides of the laryngeal prominence. Therefore, the Tianrong and Renying acupoints are selected for tonification.
If the collateral vessels at Yuji appear blue and short, it indicates Sha Qi (Shortness of Qi). (Full text available in chapters related to Yin and Yang.)
The *Huangdi Neijing Suwen* records: If the Spleen pulse is firm and long, and the complexion is yellow, the patient suffers from Sha Qi (Shortness of Qi). (From the chapter "Mai Yao Jing Wei Lun") If the pulse beats once per exhalation and once per inhalation, this is called Sha Qi (Shortness of Qi). (From the chapter "Ping Ren Qi Xiang Lun")
If the skin at the Chi position is firm and large, but the pulse is very small, this indicates Sha Qi (Shortness of Qi); if the condition worsens, death will occur immediately. (Full text available in chapters related to diagnosing firmness at the Chi position and worsening shortness of qi.)
