摘要:
A patient monitoring system may receive a physiological signal such as a photoplethysmograph (PPG) signal. The PPG signal may include a pulsatile component that functions as a carrier signal and an amplitude modulation component that represents respiration information. The patient monitoring system may move the amplitude modulation component to a baseline component of the PPG signal. Respiration information may be calculated based on the amplitude modulation component.

A patient monitoring system may receive a physiological signal such as a photoplethysmograph (PPG) signal. The PPG signal may include a pulsatile component that functions as a carrier signal and a frequency modulation component that represents respiration information. The patient monitoring system may more the frequency modulation component to a baseline component of the PPG signal. Respiration information may be calculated based on the frequency modulation component.

An apnea analysis system may include a photoplethysmographic (PPG) sub-system, a breath detection sub-system, and an apnea analysis module. An apnea analysis system includes a photoplethysmographic (PPG) sub-system, a breath detection sub-system, and an apnea analysis module. The PPG sub-system is configured to be operatively connected to an individual and output a PPG signal from the individual. The breath detection sub-system is configured to be operatively connected to the individual and output a breath signal from the individual. The apnea analysis module is in communication with the PPG sub-system and the breath detection sub-system. The apnea analysis module analyzes the breath signal and a respiratory component of the PPG signal and, based on the analysis, identifies a presence of apnea, differentiates between obstructive apnea and central apnea, and provides an indication of the identified apnea.

Embodiments of the present disclosure relate to display features that facilitate observation of monitored physiological data. According to certain embodiments, a monitoring system may include a monitor capable of receiving data related to the physiological parameters and storing data related to the parameters. The monitor may include a microprocessor configured to determine a blood pressure baseline from the data and to establish an alarm sensitivity for blood pressure based on the blood pressure baseline. The alarm sensitivity may comprise a first tier, a second tier, a third tier, and a fourth tier, and each tier may correspond to a blood pressure range. The alarm sensitivity may relate to an acceptable percent shift of the blood pressure from the blood pressure baseline, and the acceptable percent shift for at least one of the tiers is different from the acceptable percent shift of another one of the tiers.
