To quantify manual fraction of inspired oxygen (FiO(2)) adjustments performed by caregivers in extremely low birth weight (ELBW; ≤1000 g) infants, in relation to oxygen saturation (SpO(2)) and bedside care. ⋯ Manual FiO(2) adjustments varied widely in frequency and step size. Deep desaturations and large FiO(2) adjustments were associated with medical or nursing procedures. When large adjustments are really necessary, it will be challenging to implement them in an automatic adjustment device.
