EMS providers a primarily taught subjective assessment techniques for patient with respiratory problems. This includes basic observation of signs and symptoms that can often be confusing and misleading. Then providers are asked to interview patients for OPQRST-SAMPLE when they are having a hard enough time just breathing. Add to the fact that most protocols are written having therapy based on chief complaints and sometimes without sound clinical judgement. Studies have suggested this approach can be dangerous. Technological advancements have produced respiratory monitors that are much smaller in size and a fraction of the cost of our high end monitor/defibrillator with Pulse Ox and Capnography. In this presentation, Bob introduces the audience to the concepts of the big three of respiratory monitoring: Pulse oximetry, capnography, and Co-Oximetry (CO monitoring), describing their use as objective patient assessment tools, and discusses through case reviews, the impact they can have on clinical decision making for all levels of providers.
