broken. Transfer the mixture to a centrifuge tube to separate the sample into layers‚ to help remove the water. Once the sample is finished spinning extract the organic layer and place in a test tube. TLC: To determine which mixture acetone and hexane is the best developing solvent the first step is to make mixtures of these solvents in test tubes. In the first test tube mix one part acetone (.5 mL) and three parts hexane (1.5 mL)‚ In the second test tube mix two parts acetone (1 mL) and two parts

for this reason that airway and ventilation skills are a vital part of paramedic education and training (Sanders‚ 2007). Endotracheal (ET) intubation is a procedure by which a tube is inserted through the mouth down into the trachea where the patient is often unconscious at the time of the procedure. The endotracheal tube serves as an open passage through the upper airway and is considered to be the “gold standard” in the pre-hospital care setting for complete airway control.
