A system is configured to determine a fluid responsiveness index of a patient from a physiological signal. The system may include a sensor configured to be secured to an anatomical portion of the patient, and a monitor operatively connected to the sensor. The sensor is configured to sense a physiological characteristic of the patient. The monitor is configured to receive a physiological signal from the sensor. The monitor may include an index-determining module configured to determine the fluid responsiveness index through formation of a ratio of one or both of amplitude or frequency modulation of the physiological signal to baseline modulation of the physiological signal.

System and method for detecting fluid responsiveness of a patient

The present disclosure relates to systems and methods for collecting patient data via a monitoring system, with reduced power consumption. In one embodiment, the monitoring system is configured to emit pulses of light, and detect the light after passing through patient tissue. The light data is emitted sporadically, and a waveform is reconstructed from the sporadically sampled light data. Physiological parameters from the patient may be calculated from the reconstructed waveform. The sporadic sampling may reduce the power consumption by the monitoring system.

Low power monitoring systems and method

According to various embodiments, a tracheal tube may employ sensing techniques for determining a distance between the inserted tube and an anatomical structure such as a carina. The distance information may provide an indication as to whether or not the tracheal tube is properly placed within the trachea. Because a tracheal tube may rotate within the trachea, the sensing information may be gathered from multiple locations on the tracheal tube for a rotation-independent measurement technique.

Multiple channel tracheal tube placement device and technique for using the same

A system is provided including a thoracic bio-impedance or bio-reactance (TBIR) analysis module, a photoplethysmograph (PPG) analysis module, and a cardiac output module. The TBIR module is configured to obtain TBIR information from a TBIR detector, and the PPG analysis module is configured to obtain PPG information from a PPG detector. The cardiac output module is configured to determine the cardiac output of a patient using the TBIR information and the PPG information.
