Skip supplemental O2 in nonhypoxic ACS

Key clinical point: Don’t give supplemental oxygen to nonhypoxemic patients with suspected ACS.

Major finding: The 30-day mortality rate was 3.0% in suspected ACS patients randomized to the routine high-flow oxygen protocol and closely similar at 3.1% with the conservative oxygen strategy.

Study details: This cluster randomized crossover trial include all of the nearly 41,000 New Zealanders who presented with suspected acute ACS during a 2-year period.

Disclosures: The presenter reported having no financial conflicts regarding the study, funded by the National Heart Foundation of New Zealand.
