Scheele did not publish his findings until 1777. In 1772 Swedish pharmacist Carl Scheele discovered that when heating mercuric oxide and potassium nitrate, candles burned brighter. Definitive conclusions for oxygen use in these conditions where efficacy and/or safety are uncertain will require large randomized controlled clinical trials. Evidence for use with other conditions for which oxygen is administered relies on anecdotal experiences, case reports, or small, underpowered studies. Oxygen should be titrated to target an S pO 2 of 94–98%, except with carbon monoxide poisoning (100% oxygen), ARDS (88–95%), those at risk for hypercapnia (S pO 2 88–92%), and premature infants (S pO 2 88–94%). Although oxygen is administered for varied medical conditions in the hospital setting, published literature supports the use of oxygen to reverse hypoxemia, for trauma victims with traumatic brain injury and hemorrhagic shock, for resuscitation during cardiac arrest, and for carbon monoxide poisoning.
