When assessing a patient's level of consciousness, the focus is primarily on various neurological and physical responses that indicate how alert and aware the patient is. Motor function and pupillary response are critical components of this assessment. Motor function evaluates the patient’s ability to move in response to stimuli, while pupillary response checks for brain function and potential neurological issues by observing how the pupils react to light.

Vital signs are also important in the overall assessment of a patient’s condition, including heart rate, respiratory rate, and blood pressure, as these can provide insight into the patient’s physiological status, which may influence consciousness levels.

Pulse oximetry, on the other hand, measures blood oxygen saturation but does not directly assess the level of consciousness. It is an important parameter in evaluating respiratory function and oxygenation but is not a measure of cognitive awareness or responsiveness. Thus, it is not typically included in the specific evaluation of consciousness levels.
