Boyle's Law Definition - ANS>"Boyle's = Balloon = Barotrauma" The pressure of a gas is inversely proportional to the volume of a gas at a constant temperature. P1V1 = P2V Boyle's Law Affects - ANS>ETT Cuffs MAST trousers Air Splints IV drip rates (increases rate) Boyle's Law Example - ANS>If the patient has a Pneumocephalus (air inside the cranial vault after trauma, usually from a direct blow, associated with depressed skull fractures) intracranial pressure will increase Arterial Gas Embolism (AGE)
Dalton's Law Definition - ANS>"Dalton's Gang" Law of Partial Pressures (this is an additive gas law) The total pressure of a gas mixture is the sum of the partial pressures of all the gasses in the mixture. PT = P1 + P2 + P3 + ... +Pn Dalton's Law Affects - ANS>Responsible for soft tissue swelling at altitude (uptake of inert gasses into tissue) Charles' Law Definition - ANS>"Charging Charles" At a constant pressure, the volume of gas is directly proportional to the absolute temperature of the gas. V1 / T1 = V2 / T Oxygen tank getting hot when filled
Graham's Law Example - ANS>Gas bubbles coming out of exposed grey matter when at altitude. Henry's Law Definition - ANS>The solubility of a gas in a liquid The quantity of gas dissolved in 1 cm (1 ml) is proportional to the partial pressure of the gas in contact with the liquid Henry's Law Affects - ANS>Affects divers, can lead to decompression sickness, "the bends" The bends are the most common form of decompression sickness
