夫逆气者，因怒则气逆，甚则呕血，及食而气逆上。
人有逆气，不得卧而息有音者；有起居如故，而息有音者；有得卧，行而喘者；有不能
卧、不能行而喘者；有不能卧，卧而喘者，皆有所起。
其不得卧而息有音者，是阳明之逆。足三阳者下行，今逆而上行，故息有音。阳明者，
为胃脉也；胃者，六腑之海，其气亦下行，阳明逆，气不得从其道，故不得卧。夫胃不和则
卧不安，此之谓也。
夫起居如故，而息有音者，此肺之络脉逆，络脉之气不得随经上下，故留经而不行。此
络脉之疾人，故起居如故而息有音。
不得卧，卧而喘者，是水气之客。夫水者，循津液而流也；肾者水脏，主津液，津液主
卧而喘。
诊其脉，趺阳脉太过，则令人逆气，背痛温温然。寸口脉伏，胸中有逆气。关上脉细，
其人逆气，腹痛胀满。其汤熨针石，别有正方，补养宣导，今附于后。
《养生方·导引法》云∶偃卧，以左足踵拘右足拇指，鼻纳气，自极七息，除癖逆气。
厥者，逆也。谓阴气乘于阳。阴气居于下，阳气处于上，阳虚则阴实，实则阴盛，阴盛
则上乘于阳，卫气为之厥逆，失于常度，故寒从背起，手足冷逆，阴盛故也。
此由脏气不足故也。肺主于气而通呼吸，脏气不足，则呼吸微弱而少气。胸痛少气者，
水在脏腑。水者，阴气；阴气在内，故少气。
诊右手寸口脉，阴实者，肺实也。苦少气，胸内满彭彭，与膊相引，脉来濡者，虚
少气也。左手关上脉阴阳俱虚者，足厥阴、少阳俱虚也，病苦少气不能言。右手关上脉阴阳
俱虚者，足太阴、阳明俱虚也，病苦胃中如空状，少气不足以息，四逆寒。脉弱者，少气，
皮肤寒。脉小者，少气也。
所谓逆气，是因为发怒导致气机逆乱，严重时会出现呕血，以及在进食时气机上逆。
人出现逆气的情况有：无法平卧且呼吸有声的；起居如常但呼吸有声的；能够平卧但行走时喘息的；既不能平卧也不能行走而喘息的；以及不能平卧、一躺下就喘息的。这些症状都有各自的成因。
那些无法平卧且呼吸有声的，是阳明经气逆乱所致。足三阳经的气本应下行，如今反而上行，所以呼吸有声。阳明经属于胃脉；胃为六腑之海，其气也应当下行。如果阳明经气逆乱，气就不能顺着正常的通道运行，因此无法安卧。这就是所说的“胃不和则卧不安”。
那些起居如常但呼吸有声的，这是肺的络脉之气逆乱。络脉之气不能随着经脉上下运行，因而滞留于经脉中不流通。这类络脉病变的患者，所以起居如常但呼吸有声。
不能平卧、一躺下就喘息的，是水气客居体内所致。水液是跟随津液流动的；肾是水脏，主管津液，津液代谢失常导致躺下时喘息。
诊察脉象时，趺阳脉过于有力，会导致人出现逆气，背部疼痛且有温热感。寸口脉沉伏，说明胸中有逆气。关上脉细弱，其人会有逆气、腹痛和胀满。针对这些情况的汤药、熨贴、针刺和砭石治疗，另有专门的方剂，补益调养和导引宣通的方法，现附在后面。
《养生方·导引法》说：仰卧，用左脚脚跟勾住右脚大拇指，鼻子吸气，尽力做到极致，共做七次呼吸，可以消除癖积和逆气。
厥，就是逆乱的意思。指阴气侵犯阳气。阴气居于下部，阳气居于上部，阳气虚弱则阴气相对充实，阴气充实则阴盛，阴盛就会上乘于阳位，卫气因此发生厥逆，失去常态，所以寒气从背部升起，手足冰冷逆冷，这是因为阴气过盛。
这种情况是由于脏腑之气不足造成的。肺主气并通于呼吸，脏腑之气不足，就会导致呼吸微弱和气短。胸痛且气短的，是因为水饮停留在脏腑。水属阴气；阴气在内停留，所以气短。
诊察右手寸口脉，阴实（邪气盛）的，是肺实证。苦于气短，胸部内部胀满膨隆，牵引两臂，脉象来势濡软的，是虚证导致的气短。左手关上脉阴阳俱虚的，是足厥阴肝经和足少阳胆经都虚，病症表现为苦于气短且不能言语。右手关上脉阴阳俱虚的，是足太阴脾经和足阳明胃经都虚，病症表现为苦于胃中空虚感，气短不足以呼吸，四肢逆冷。脉象弱的，是气短，皮肤寒冷。脉象小的，也是气短。
The term "rebellious Qi" (Ni Qi, rebellious Qi) refers to the condition where anger causes Qi to rebel; in severe cases, it leads to vomiting blood and upward rebellion of Qi during eating.
There are several manifestations of rebellious Qi: some patients cannot lie down and have noisy breathing; some have normal daily activities but noisy breathing; some can lie down but wheeze when walking; some cannot lie down or walk yet wheeze; and some cannot lie down and wheeze as soon as they lie down. All these conditions have specific origins.
Those who cannot lie down and have noisy breathing suffer from rebellion of the Yangming channel. The three Yang channels of the foot normally descend; now they rebel and ascend, causing noisy breathing. The Yangming channel belongs to the Stomach meridian; the Stomach is the sea of the six Fu organs, and its Qi also descends. When Yangming Qi rebels, it cannot follow its proper pathway, thus preventing sleep. This is what is meant by "when the Stomach is disharmonious, sleep is uneasy."
Those whose daily activities remain normal but have noisy breathing suffer from rebellion of the collateral vessels of the Lung. The Qi of the collateral vessels cannot move up and down with the main meridians, so it stagnates in the meridians and does not circulate. Therefore, patients with this collateral vessel disease have normal daily activities but noisy breathing.
Those who cannot lie down and wheeze upon lying down are affected by Water Qi invading the body. Water flows following the Jin-Ye (body fluids); the Kidney is the Water organ and governs Jin-Ye. Dysfunction in Jin-Ye management leads to wheezing when supine.
Upon pulse diagnosis, an excessive pulse at the Duzhong (Fuyang) point indicates rebellious Qi and back pain with a warm sensation. A hidden pulse at the Cunkou (Radial) point indicates rebellious Qi in the chest. A thin pulse at the Guanshi (Cun position) indicates rebellious Qi, abdominal pain, and distension. For these conditions, treatments involving decoctions, moxibustion/heat application, acupuncture, and stone therapy have separate specific formulas. Methods for nourishing, supplementing, and guiding Qi are attached below.
The *Yangsheng Fang* (Prescriptions for Nourishing Life) · *Daoyin Fa* (Guiding and Pulling Methods) states: Lie on your back, hook the right big toe with the left heel, inhale through the nose, exert yourself to the limit, perform seven breath cycles, which eliminates masses and rebellious Qi.
Jue (Cold Extremities/Rebellion) means rebellion. It refers to Yin Qi attacking Yang Qi. Yin Qi resides in the lower part, while Yang Qi resides in the upper part. When Yang is deficient, Yin becomes relatively full; when full, Yin is excessive. Excessive Yin attacks the upper Yang region, causing the Wei Qi (Defensive Qi) to rebel and lose its normal rhythm. Consequently, cold arises from the back, and the hands and feet become cold and reversed due to excess Yin.
This condition arises from insufficiency of Zang organ Qi. The Lung governs Qi and connects with respiration. Insufficiency of Zang Qi results in weak respiration and shortness of breath. Chest pain accompanied by shortness of breath indicates water retention within the Zang organs. Water is Yin Qi; when Yin Qi stays inside, it causes shortness of breath.
Diagnosing the Right Hand Cunkou pulse: If Yin is solid (excess), it indicates Lung excess. Suffering from shortness of breath and fullness/pounding in the chest that radiates to the shoulders, with a soft (Ru) pulse coming, indicates deficiency-type shortness of breath. If the Left Hand Guanshi pulse shows both Yin and Yang as deficient, it indicates deficiency of the Foot Jueyin Liver and Foot Shaoyang Gallbladder channels. The disease manifests as suffering from shortness of breath and inability to speak. If the Right Hand Guanshi pulse shows both Yin and Yang as deficient, it indicates deficiency of the Foot Taiyin Spleen and Foot Yangming Stomach channels. The disease manifests as suffering from a hollow feeling in the stomach, shortness of breath insufficient for respiration, and four extremities cold/reversed. A weak pulse indicates shortness of breath and cold skin. A small pulse also indicates shortness of breath.
