AHA 2020 GUIDELINES:
"EMS providers should administer oxygen if the patient is dyspneic, is hypoxemic, has obvious signs of heart failure, has an arterial oxygen saturation less than 90% or unknown. Providers should adjust oxygen therapy to a noninvasively monitored oxyhemoglobin saturation 90% or greater. The usefulness of supplemental oxygen therapy has not been established in normoxic patients with suspected or confirmed acs, so providers may consider withholding it in these patients [29]
In addition, guidelines states"Give supplemental O2 when indicated. For Cardiac arrest patients, administer 100% for oxygen. For others adjust oxygen administration to achieve oxygen saturation of 95% to 98% by pulse oximetry (90% for ACS and 92% to 98% for post-cardiac arrest care. [29] |
