In 40 CFR 156.62, the EPA established four Toxicity Categories for acute hazards of pesticide products, with "Category I" being the highest toxicity category (toxicity class). Most human hazard, precautionary statements, and human personal protective equipment statements are based upon the Toxicity Category of the pesticide product as sold or ...
First, previous classes 5 and 6 were removed and a new class 5 was added for moribund persons not expected to survive 24 hours, with or without surgery. Second, separate classes for emergencies were eliminated in lieu of the "E" modifier of the other classes. [13] [14] The sixth class is now used for declared brain-dead organ donors. Saklad ...
Double pneumonia is a historical term for acute lung injury (ALI) or acute respiratory distress syndrome (ARDS). [15] However, the term was, and, especially by lay people, still is used to denote pneumonia affecting both lungs. Accordingly, the term double pneumonia is more likely to be used to describe bilateral pneumonia than it is ALI or ARDS.

It addresses the acute toxicity of agents such as soil fumigants , fungicides , herbicides , insecticides , miticides , molluscicides , nematicides , or rodenticides .
Acute toxicity describes the adverse effects of a substance that result either from a single exposure [1] or from multiple exposures in a short period of time (usually less than 24 hours). [ 2 ] To be described as acute toxicity, the adverse effects should occur within 14 days of the administration of the substance.
In medicine, describing a disease as acute denotes that it is of recent onset; it occasionally denotes a short duration.The quantification of how much time constitutes "short" and "recent" varies by disease and by context, but the core denotation of "acute" is always qualitatively in contrast with "chronic", which denotes long-lasting disease (for example, in acute leukaemia and chronic ...
Acute respiratory acidosis occurs when an abrupt failure of ventilation occurs. This failure in ventilation may be caused by depression of the central respiratory center by cerebral disease or drugs, inability to ventilate adequately due to neuromuscular disease (e.g., myasthenia gravis, amyotrophic lateral sclerosis, Guillain–Barré syndrome, muscular dystrophy), or airway obstruction ...
Killip class II includes individuals with rales or crackles in the lungs, an S 3, and elevated jugular venous pressure. Killip class III describes individuals with frank acute pulmonary edema . Killip class IV describes individuals in cardiogenic shock or hypotension (measured as systolic blood pressure lower than 90 mmHg), and evidence of ...
