1. A noninvasive method of analyzing oxygen saturation of a patient, the method comprising:
- deriving oxygen saturation values from a patient, the oxygen saturation values reflecting oxygen saturation of blood at a tissue site over a respiration cycle of the patient;
calculating a difference between a maximum and a minimum of the derived oxygen saturation values over the respiration cycle;
outputting an indication of the difference between the maximum and the minimum of the derived oxygen saturation values; and
outputting an indication of a risk of overextension of alveoli of the patient.

Abstract
A physiological monitoring system can include a physiological monitor having one or more processors that can derive oxygen saturation values from a patient. The oxygen saturation values can correspond to values of oxygen saturation in blood at a tissue site of the patient. The physiological monitor can output an indication of amplitude of the differences per respiratory cycle in the oxygen saturation values.
