Abstract: One embodiment is a method of extracting respiratory parameters from a short duration thoracic impedance (“TI”) signal, the method comprising preprocessing the TI measurement signal to obtain a respiratory signal therefrom; assessing the respiratory signal for at least one of signal quality and signal integrity; executing at least one of an autocorrelation algorithm and a time-domain zero-crossing algorithm on the respiratory signal to extract at least one respiratory parameter therefrom, the at least one respiratory parameter comprising at least one of respiration rate (“RR”) and tidal volume (“TV”).
