Respiratory profile parameter determination apparatus
First Claim
1. Apparatus for monitoring and displaying data obtained from respiration of an individual, comprising:
- at least one respiratory monitor;
at least one processing element in communication with the at least one respiratory monitor and configured to;
evaluate a signal generated by the at least one respiratory monitor while monitoring respiration of the individual;
calculate at least one respiratory parameter based on the signal; and
estimate at least one blood gas parameter based on at least one of the signal and the at least one respiratory parameter; and
a display element in communication with at least one of the at least one processing element and the at least one respiratory monitor, and including an indicator comprising a graph including at least one bar, each bar comprising a plurality of sections representing a plurality of complementary parameters of the at least one respiratory parameter or the at least one blood gas parameter obtained at substantially the same time, a first section illustrating a first parameter corresponding to breathing effected by the individual and a second section illustrating a second parameter corresponding to breathing effected by a mechanical ventilator.

Abstract
A method of sampling one or more respiratory profile characteristics and monitoring a variety of respiratory profile parameters. The sampled respiratory characteristics include respiratory flow rate, respiratory pressure, and partial pressure of at least one constituent of a patient'"'"'s respiration. The method detects patient breaths, determines whether each breath is a spontaneous breath or a ventilator-induced breath and calculates various respiratory profile parameters based on the sampled measurements. The method displays the respiratory profile parameters in graphic and numeric forms. Preferably, the method allows a user to select the displayed respiratory profile parameters.
