The termination of pulmonick inflammation is by resolution, by suppuration, by gangrene, by fatal effusion of blood, or exudation of coagulable lymph into the cellular texture. Favourable symptoms are, as in anginous excreation, facility in expectoration, without much exertion or coughing, copious, of due consistence, a little yellow, white, thick, slightly streaked with blood; the sooner this is concocted and excreted, the sooner is the crisis; less urgent and painful cough; freer breathing; abatement in the heat of the body and velocity of the pulse; general perspiration; deposition of sediment in the urine; nasal hemorrhage; dispersion of the pain, hitherto fixed in the thorax, about the shoulders, back, or arms; erysipelas in some external part; pustular eruption about the breast, neck, and scapulæ; abscesses in different parts. A crisis, when favourable, always ensues within seven, or at the utmost fourteen days; and after such crisis, expectoration may continue copious several days.
Inauspicious symptoms are, the respiration struggling and laborious in the extreme; dry pertinacious cough; no expectoration, or with difficulty; suppressed expectoration; obtuse pain, with difficult respiration; frequent violent cough exasperating the pain; the pain changing from one side into the other; the pulmonick lobes in both sides inflamed; the breathing intolerable and suffocating, except in an erect posture, and even then with laborious anxiety; the face turgid and florid, or pale, with features of consternation; violent headach; delirium; remission succeeded by relapse; excessive sweats; dry skin; weak, soft, and irregular pulse; sudden cessation of pain; grumous livid expectoration; rattling noise in the thorax, as if plugged up by phlegm; dejected countenance, squalid sunk eyes; great prostration of strength; cold clammy partial sweats; limpid urine; florid blood coughed up, or white and glutinous matter resembling the branches of blood-vessels. Effusion of blood, and exudation of coagulable lymph into the pulmonary cellular texture, bronchial vesicles and air-pipes, is more frequently than gangrene, the cause of suffocation and death. The occurrence of either is seldom later than fourteen days. There is also great danger of pulmonick inflammation, persevering beyond seven or, at the utmost, fourteen days, and without any considerable remission or signs of resolution, terminating in suppuration; of which the diagnosticks are hereafter marked. Authors have likewise described a malignant peripneumony, which seems to be a complication of the preceding deleterious symptoms, and of putrid fever.
