Basic treatment: Establish a patent airway. Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 6 to 12 L/min. Monitor for pulmonary edema and treat if necessary ... . Monitor for shock and treat if necessary ... . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with normal saline during transport ... . Do not use emetics. For ingestion, rinse mouth and administer 5 mL/kg up to 200 mL of water for dilution if the patient can swallow, has a strong gag reflex, and does not drool ... . Do not attempt to neutralize. Cover the skin burns with dry sterile dressings after decontamination ... . /Inorganic Bases/Alkaline Corrosives and Related Compounds/

Advanced treatment: Consider orotracheal or nasotracheal intubation for airway control in the patient who is unconscious or in respiratory arrest. Early intubation, at the first signs of upper airway obstruction, may be necessary. Positive-pressure ventilation techniques with a bag-valve-mask device may be beneficial. Monitor cardiac rhythm and treat arrhythmias as necessary ... . Start an IV of D5W TKO /SRP: "To keep open", minimal flow rate/. Use lactated Ringer's if signs of hypovolemia are present. Watch for signs of pulmonary edema. For hypotension with signs of hypovolemia, administer fluid cautiously. Watch for signs of fluid overload ... . Consider drug therapy for pulmonary edema ... . Use proparacaine hydrochloride to assist eye irrigation ... . /Inorganic Bases/Alkaline Corrosives and Related compounds/

Phosphate is a major intracellular anion which participates in providing energy for metabolism of substances and contributes to important metabolic and enzymatic reactions in almost all organs and tissues. Phosphate exerts a modifying influence on calcium concentrations, a buffering effect on acid-base equilibrium, and has a major role in the renal excretion of hydrogen ions. /Phosphate/

Phosphate as nutrient is a limiting factor to plant growth. /Phosphate/

Phosphate is a major intracellular anion which participates in providing energy for metabolism of substances and contributes to important metabolic and enzymatic reactions in almost all organs and tissues. Phosphate exerts a modifying influence on calcium concentrations, a buffering effect on acid-base equilibrium, and has a major role in the renal excretion of hydrogen ions.

Once phosphate gains access to the body fluids and tissues, it exerts little pharmacological effect. If the ion is introduced into the intestine, the absorbed phosphate is rapidly excreted. If large amounts are given by this route, much of it may escape absorption. Because this property leads to a cathartic action, phosphate salts are employed as mild laxatives.

If large amounts are given by this route, much of it may escape absorption. Because this property leads to a cathartic action, phosphate salts are employed as mild laxatives. Inorganic phosphate poisoning following ingestion of laxatives that contain phosphate salts has been reported in adults and children. Ingestion of large amounts of sodium dihydrogen phosphate lowers urinary pH. If excessive phosphate salts are introduced intravenously or orally, they may prove toxic by reducing the concentration of Ca 2+ in the circulation and from the precipitation of calcium phosphate in soft tissues. /Phosphates/

Potassium salts are well absorbed from gastro intestinal tract. Net phosphorus absorption may occur in the small intestine in some species but is primarily a function of the colon in horses.

Potassium is excreted primarily by kidney.

Distribution is largely intracellular, but it is the intravascular concentration that is primarily responsible for toxicity.

Phosphates are rapidly cleared by dialysis.

Buffering agent in anti-freeze; nutrient in the culturing of antibiotics

Sequestrant; emulsifier in specified cheeses

Most of the commercial output of dipotassium phosphate is used in conjunction with borates, nitrites, nitrates, and/or silicates as corrosion inhibitor systems in ethylene glycol antifreeze formulations. Its second largest use is as a buffer in coffee creamers to prevent casein protein precipitation by coffee acids. Other uses include specialty fertilizers, paper-processing aids, and saline cathartics.
