The process of adjusting oxygen to maintain target SpO2 is called?

• A. Calibration
• B. Titration
• C. Ventilation
• D. Administration

Answer: (B)

Titration is the process of adjusting the amount of oxygen given so that the patient's SpO2 stays within a prescribed range. In practice, you start with an initial oxygen level, monitor SpO2 with a pulse oximeter, and make small changes to FiO2 or flow until the target saturation is reached and maintained. The goal is to avoid both too little oxygen (hypoxia) and too much oxygen (hyperoxia).

Calibration is about ensuring the measurement device is accurate, not about changing therapy. Ventilation refers to the movement of air in and out of the lungs or providing ventilatory support, not the adjustment of oxygen to hit a saturation target. Administration is a broad term for delivering therapy, but it doesn’t specify the ongoing adjustment to maintain the target SpO2.
