Why are chemical accidents increasing?
Because thousands of chemicals are manufactured, used, and transported in the United States, the number of accidents involving chemical exposures is increasing. Although most of these accidents occur at fixed facilities where the chemical hazards are known, emergency medical personnel are increasingly more likely to be involved in incidents in which victims have been exposed to an unknown or incorrectly identified chemical hazard. Emergency medical technicians, therefore, must learn to deal with presenting symptoms and provide basic supportive medical care for complications (respiratory, cardiovascular, and neurologic) that are most likely to cause a serious threat to life.
How long does an acute exposure last?
An acute exposure is defined as an exposure to a chemical for a duration of 14 days or less. Although the duration of exposure during an unscheduled chemical release may be brief, the chemical concentration may be high. The onset of health effects resulting from an acute exposure can be immediate or delayed.
What is prehospital management?
In the Prehospital Management section we describe the activities that typically occur in the three concentric circular areas surrounding a hazardous materials incident ( Figure 1) and ( Figure 2 ), particularly those activities that relate to Emergency Medical Services (EMS) personnel. The information provided is based on the consensus of a panel of experts and is an attempt to offer an accurate and practical approach to management of hazardous materials emergencies. The user of the protocols should be aware, however, that there are large "data gaps" in the scientific literature, especially about clinical signs and symptoms of poisoning and about medical treatment.

Inhalation of formaldehyde can cause airway irritation, bronchospasm, and pulmonary edema. Formaldehyde absorption can cause severe systemic toxicity leading to metabolic acidosis and coma. There is no specific antidote for formaldehyde poisoning. Treatment consists of supportive measures.
Is HF a mineral?
HF differs from most other mineral acids. In addition to its corrosive effect as an acid, the fluoride ion readily penetrates the skin, causing destruction of deep tissues. Absorption of significant amounts of HF by any route may be fatal.
Which organ is the primary site of drug metabolism?
Metabolism involves complex biochemical pathways and reactions that alter drugs, nutrients, vitamins, and minerals. The liver is the primary site of drug metabolism, although the kidneys and cells of the intestinal tract also have high metabolic rates.
What is the study of drug movement throughout the body?
pharmacokinetics (page 37) is derived from the root words pharmaco, which means "medicine," and kinetics, which means "movement or motion.". Pharmacokinetics is thus the study of drug movement throughout the body.
What is the blood-brain barrier?
blood-brain barrier (page 40) anatomical structure that prevents certain substances from gaining access to the brain. conjugates (page 40) side chains that, during metabolism, make drugs more water soluble and more easily excreted by the kidney. dissolution (page 37) determines how quickly the drug disintegrates and disperses into simpler forms;
Which organs receive the most blood?
The heart, liver, kidneys, and brain receive the most blood supply. Skin, bone, and adipose tissue receive a lower blood supply; therefore, it is more difficult to deliver high concentrations of drugs to these areas. drug-protein complex (page 39) rugs bind reversibly to plasma proteins, particularly albumin.
What is enterohepatic recirculation?
enterohepatic recirculation (page 42) recycling of drugs and other substances by the circulation of bile through the intestine and liver. Biliary reabsorption is extremely influential in prolonging the activity of cardiac glycosides, some antibiotics, and phenothiazines.
What is enzyme induction?
enzyme induction (page 40) process in which a drug changes the function of the hepatic microsomal enzymes and increases metabolic activity in the liver. For example, phenobarbital causes the liver to synthesize more microsomal enzymes.
What is loading dose?
loading dose (page 44) is a higher amount of drug, often given only once or twice to "prime" the bloodstream with a sufficient level of drug.
What is chemical digestion?
Chemical digestion involves the secretions of enzymes throughout your digestive tract. These enzymes break the chemical bonds that hold food particles together. This allows food to be broken down into small, digestible parts.
Where does mechanical digestion begin?
Mechanical digestion begins in your mouth with chewing, then moves to churning in the stomach and segmentation in the small intestine. Peristalsis is also part of mechanical digestion.
What is the process of breaking down food?
Chemical and mechanical digestion are the two methods your body uses to break down foods. Mechanical digestion involves physical movement to make foods smaller. Chemical digestion uses enzymes to break down food.
How does the small intestine work?
How they work together. Once food particles reach your small intestine, the intestines continue to move. This helps keep food particles moving and exposes more of them to digestive enzymes. These movements also help to move the digested food toward the large intestine for eventual excretion.
What is the main site of digestion?
The small intestine is a major site for chemical digestion and absorption of key food components, such as amino acids, peptides, and glucose for energy. There are lots of enzymes released in the small intestine and from the nearby pancreas for digestion.
How does food travel through the digestive system?
As food travels from your mouth into your digestive system, it’s broken down by digestive enzymes that turn it into smaller nutrients that your body can easily absorb. This breakdown is known as chemical digestion. Without it, your body wouldn’t be able to absorb nutrients from the foods you eat.
What is the difference between mechanical and chemical digestion?
However, chemical digestion means food is broken down into small molecules by chemical energy.
Where does mechanical digestion take place?
In the mouth, both mechanical and chemical digestion takes place. 2. Pharynx. The pharynx is the place where food is swallowed. The pharynx is the part of the digestive tract that leads to the esophagus. The epiglottis is located within the pharynx.
What is mechanical digestion?
Mechanical digestion involves the process of physically breaking down the food into ever smaller parts. The major player in mechanical digestion is mastication, which is the act of chewing and using the teeth to break the food into pieces small enough to be swallowed into the esophagus. This type of digestion generally starts and occurs in ...
How does digestion work?
Mouth. In the mouth, larger pieces of food are chewed into pieces by the teeth and by mastication. There are 32 adult teeth, each of which has a special purpose.
What is the enzyme that breaks down carbohydrates?
Saliva has an enzyme known as amylase that is important in breaking down carbohydrates. As an enzyme, amylase is a type of protein that undergoes a biochemical reaction to change one molecule into another molecule. Most chemical digestion, however, occurs within the stomach, with some happening in the intestines.
Where does amylase occur?
Most chemical digestion, however, occurs within the stomach, with some happening in the intestines. The hydrochloric acid, located in the stomach, works for the purposes of chemical digestion.
What is the role of the tongue?
Its role is to transfer the food to the back of the mouth and to move it around, so it can be broken down. There are also the salivary glands in and around the mouth that secrete the enzymes in saliva that begin the digestive process.
What is diagnostic process?
The committee concluded that the diagnostic process is a complex, patient-centered, collaborative activity that involves information gathering and clinical reasoning with the goal of determining a patient's health problem.
Why is time important in diagnostics?
Time. Of major importance in the diagnostic process is the element of time. Most diseases evolve over time, and there can be a delay between the onset of disease and the onset of a patient's symptoms; time can also elapse before a patient's symptoms are recognized as a specific diagnosis (Zwaan and Singh, 2015).
What is the purpose of a clinical history interview?
Performing a clinical history and interview, conducting a physical exam, performing diagnostic testing, and referring or consulting with other clinicians are all ways of accumulating information that may be relevant to understanding a patient's health problem.
What is physical exam?
Physical Exam. The physical exam is a hands-on observational examination of the patient. First, a clinician observes a patient's demeanor, complexion, posture, level of distress, and other signs that may contribute to an understanding of the health problem (Davies and Rees, 2010).
What is clinical reasoning?
Clinical reasoning is “the cognitive process that is necessary to evaluate and manage a patient's medical problems ” (Barrows, 1980, p. 19).
