    摘要: A device for measuring the capillary refill time of a patient and for use in determining an amount of oxygen in the blood of the patient has light sources and a light detector for use in carrying out pulse oximetry. The device also includes an actuator for applying pressure to a selected portion of the body of the patient, such as the nail bed of a finger or toe of the patient, to cause the removal of blood from the nail bed when actuated. A timer commences a time interval with a deactuation of the actuator. The deactuation relieves the pressure applied by the actuator to the body portion of the patient and allows blood to return to the portion. The timing interval is terminated by a reduction in the amount of light received by the light detector as a result of the restoration of blood to the body portion. The time interval so determined comprises an indication of the capillary refill time of the patient. Compensation in accordance with a skin temperature measurement may be provided.

    摘要: A system and method of monitoring the fluid status of a patient. The system may include a patient monitor that receives blood pressure data. A first fluid model receives the blood pressure data, and a personalized fluid model is derived from the application of the blood pressure data to the first fluid model. An estimation of the patient's fluid status may be derived from the personalized fluid model. The method may include the steps of measuring a first blood pressure value, creating a personalized fluid model, measuring a second blood pressure value, applying the second blood pressure value to the personalized fluid model; and deriving an estimation of the fluid status of the patient.
