摘要：
A capnograph device (10) includes a carbon dioxide measurement component (20) and an electronic processor (30) programmed to generate a capnogram (40) comprising carbon dioxide level sample values measured as a function of time. End-tidal carbon dioxide (etC02) is determined from the capnogram, and an etC02 parameter quality index (etC02 PQI) (44) is computed using one or more quantitative capnogram waveform metrics computed from the capnogram. A respiration rate (RR) value is also determined from the capnogram, and a RR PQI (46) computed using the RR value and the etC02 PQI. A respiratory well-being index (RWI) (50) may be computed from the etC02 and RR values and the etC02 and RR PQI values. In some embodiments the one or more capnogram waveform metrics are computed from a capnogram histogram generated from the capnogram
