System and method for monitoring pre-eclamptic patients
First Claim
1. A system for monitoring and estimating the blood pressure of a pregnant patient, the system comprising:
- a non-invasive blood pressure (NIBP) monitor including a blood pressure cuff positionable on the patient, the NIBP monitor including a processor operable to receive oscillation signals from a transducer within the blood pressure cuff and estimate the patient'"'"'s blood pressure based upon the oscillation signals; and
a carbon monoxide detection device operable to determine the carbon monoxide level present within the patient,wherein the processor modifies the blood pressure estimate based upon the detected carbon monoxide level.

Abstract
A system and method for monitoring and estimating the blood pressure of a pregnant patient that modifies the blood pressure estimating algorithm when the patient is pre-eclamptic. The level of carbon monoxide within a patient'"'"'s bloodstream or exhaled breath can be analyzed to determine whether a pregnant patient is pre-eclamptic. After the patient has been diagnosed as pre-eclamptic, the NIBP monitoring system adjusts its algorithm for estimating the patient'"'"'s blood pressure to compensate for the physical changes that occur in the patient during pre-eclampsia. The adjusted blood pressure estimates calculated by the NIBP monitoring system can be calculated using different adjustment techniques and methods and are displayed on the NIBP monitor.

8. A method of monitoring blood pressure in a pregnant patient, the method comprising the steps of:
-
providing a non-invasive blood pressure (NIBP) monitor operable to estimate the blood pressure of the patient and generate at least an estimated systolic pressure and an estimated diastolic pressure; positioning a carbon monoxide detection device on the patient to detect the level of carbon monoxide in the patient'"'"'s blood; receiving an indication of the carbon monoxide level in the blood of the patient at the NIBP monitor; determining whether the patient is pre-eclamptic based upon the received carbon monoxide level; adjusting the blood pressure estimates of the NIBP monitor to compensate for the effects of pre-eclampsia; and displaying the adjusted blood pressure estimates. - View Dependent Claims (9, 10, 11, 12, 13)
