Claim:
1. An apparatus for predicting onset of patient respiratory instability wherein patient respiratory instability is defined as a condition associated with a low ratio of arterial oxygen partial pressure (PaO 2 ) to fraction of inspired oxygen (FiO 2 ), the apparatus comprising: a vital signs display monitor configured to acquire and display patient data of a patient related to respiratory stability including at least Mean Airway Pressure (MAWP) and Plateau Pressure (PP) parameters; and an analyzer comprising a microprocessor or microcontroller, the analyzer programmed to compute at least one measure of predicted patient respiratory stability over a prediction time interval of duration 36 hours or less and having a starting time in a range of a current time to 24 hours in the future, the analyzer applying at least one rule to the patient data, the at least one rule being based on a plurality of parameters including at least one of the MAWP and PP parameters monitored by the monitoring system which, in combination, have been identified as being predictive of patient respiratory instability, and based on the application of the at least one rule, determines the measure of predicted patient respiratory stability over the prediction time interval, the analyzer further configured to output an alert when the measure of predicted patient respiratory stability over the prediction time interval meets a threshold indicative of respiratory instability; wherein the vital signs display monitor is further configured to display the measure of predicted patient respiratory stability over the prediction time interval computed by the analyzer.
