Oxygen, an atmospheric gas increases saturation of hemoglobin oxygen and when used at therapeutic

concentrations may aid the oxygenation of certain tissues as long at the patient is

not in shock or has some other complication like carbon monoxide poisoning which could

affect the distribution or reception of oxygen within the body and it’s cells.

The primary indications for the use of oxygen in ACLS are the presence of hypoxemia which

would be an SpO2 less than 94%, severe respiratory depression or distress as in asthma, respiratory

distress or depression as in opioid overdose.

Now when administering oxygen therapy after the return of spontaneous circulation otherwise

known as ROSC, it’s important to deliver sufficient oxygenation to maintain an SpO2

that is greater than or equal to 94% but less than 100%.

There are few if any known contraindications for oxygen use in the true hypoxic patient.

Precautions should be based on new and ongoing research revealing the vasoconstrictive properties

that hyperoxia may produce.

Now if we begin to hyperoxygenate a normoxic cardiac patient, some theories and studies

indicate that we could be causing lower oxygen absorption and distribution to vital organs

that need oxygenation during a coronary crisis.

The appropriate dose of oxygen is dependant upon the needs of the patient and their unique

oxygen requirements.

Now that being said, oxygen has several different methods for delivery and the percentage of

oxygenation is regulated by the flow of oxygen per minute and the delivery adjunct used.

Now if oxygen delivery by nasal cannula is indicated, it would be delivered at a rate

of 2 to 6 Liters per minute.

If a nonrebreather mask is used the flow rate increases to 12 to 15 Liters per minute.

If the respiratory distressed or depressed or those who are apneic completely, the delivery

of oxygenated ventilations would be delivered via a positive pressure device like a bag

valve mask.

In this case, oxygen flow should be set at 15 Liters a minute.

It’s important that under current guidelines, we are titrating oxygen therapy to maintain

an SpO2 of at least 94% but less than 100%.

It’s vital to remember that a restricted airway will affect the therapeutic response

of the oxygenation treatment.

Use of a basic or advanced airway adjunct may be needed in order to open or maintain

an open and patent airway in order to treat the patient effectively.

Now remember to monitor the patient’s signs and symptoms along with the electronic and

technical monitoring systems so as to treat the patient effectively.

In other words, if the SpO2 reads 92% but the skin appears normal in the patient, maybe

they have an underlying blood disorder like anemia which can impede the cyanosis due to

a lack of hemoglobin and give an inaccurate appearance of adequate oxygenation.
