Pulse Oximetry Assessment Tips (#31daysofCE) is a post from: Everyday EMS Tips You should be able to tell from the doorway if your patient needs oxygen. Simply gauge their rate and effort of breathing. I don’t think you need a “room air” pulse ox to confirm if the patient needs oxygen. If a patient really needs oxygen because they have: tachypnea bradypnea pallor cyanosis intercostal muscle retractions nasal flaring accessory muscle use Don’t delay oxygen administration to apply a pulse oximeter. At that point the reading, usually lower than even you might expect is merely interesting. And what are you going to do if the pulse ox says 94%? Not treat the respiratory distress. If you see respiratory distress treat it by correcting ventilation and/or perfusion problems. EMS Service Manager Aaron Scharf , Manager of the EMS Department at Long Island College Hospital shared his thoughts about pulse oximetry with me: “As far as pulse oximetry goes – and this is a pet peeve of mine with newly certified EMTs. They rely on the handheld device for evaluation of a patient’s pulse. The EMT will simply stick the probe on a patient’s finger, read off the numbers to their partner, and move along with the patient assessment. The things that are obviously missing from using this approach are the inability to determine quality and regularity of a pulse. The thing that’s less obvious, but I think more crucial is the fact that it eliminates physical contact with the patient which I think this is especially important for pediatric and geriatric patients.” Aaron continues, “We are called to someone’s house, usually a stranger, and we establish an intimate relationship with them based upon the trust and presumed competence they infer from our uniform, level of certification, and our professional demeanor. But the further we remove ourselves from that patient by allowing equipment to intervene, the more we contribute to the dehumanization of medicine.” Patient assessment is a hands-on process that also allows us to use our senses. Respiratory and pulse assessment should involved careful looking, listening, and feeling for more than just confirming the presence of breathing and the presence of a pulse.
