A method for adjusting environmental parameters for patient condition monitoring comprising: inputting via a user interface a patient condition and other information relating to the patient； searching a database for environmental parameters and other information relating to the patient condition； determining environmental parameters to adjust based on the patient condition； defining oxygen saturation level threshold ranges corresponding to various sets of environmental parameters； measuring via a pulse oximeter a first oxygen saturation level of the patient under a first set of environmental parameters； adjusting the environmental parameters corresponding to the patient condition if the first oxygen saturation level lies outside the threshold ranges defined for the first set of environmental parameters； and measuring a second oxygen saturation level of the patient under the adjusted environmental parameters.
