摘要： The invention relates to a method and a device for removing respiratory artefacts in invasive blood pressure measurements. The level of CO2 in the expired air is monitored during blood pressure measurement and used to approximate and remove the respiratory artifacts. In one embodiment, the respiratory frequency from the respiratory signal is extracted by identifying the end-tidal CO2 level for each breath. A model is derived for the respiratory artifacts using the respiratory frequency, and the model is subtracted from the measured blood pressure data.

摘要： In a computerized system and method for scheduling medical procedures implemented by a number of medical apparatuses in a clinic or hospital, an exam or therapy is scheduled using a particular medical apparatus with a set time duration, and the exam or therapy is conducted and the actual time duration occupied by the medical apparatus to conduct the exam or therapy is recorded. The time durations for each medical procedure conducted by each medical apparatus are entered into and stored in a statistical data base. A scheduling computer has access to this statistical data base, and the next exam or therapy for the same apparatus is then scheduled using a time duration that is statistically updated based on the statistical compilation in the data base.
