Abstract

An example method is performed by a computing device executing instructions stored in data storage, and includes receiving physiologic monitoring data from a plurality of sensors coupled to a patient, receiving information indicating a measurement of patient motion during the patient care event, determining whether the measurement of patient motion is above a threshold, based on determining whether the measurement of patient motion is above the threshold, generating, for the physiologic monitoring data, a respective quality indicator, analyzing, by the computing device, (i) a combination of the physiologic monitoring data from the plurality of sensors and (ii) the respective quality indicator for the physiologic monitoring data to generate a response dependent upon the combination of the physiologic monitoring data as weighted by the respective quality indicator, and based on analyzing, outputting caregiver feedback by the computing device according to the response.

First claim

What is claimed is:

1. A method performed by a computing device executing instructions stored in data storage, the method comprising:
receiving physiologic monitoring data from a sensor coupled to a patient during a patient care event, wherein the sensor has an associated motion, position, and/or orientation (MPO) sensor external from the sensor and configured to output information indicating a measurement of patient motion during the patient care event;
based on the physiologic monitoring data indicating a substantive change, interrogating the MPO sensor;
generating, for the physiologic monitoring data, a quality indicator based on determining that the measurement of patient motion received from the MPO sensor is above a threshold; and
outputting caregiver feedback by the computing device based on analyzing the physiologic monitoring data from the sensor as weighted by the quality indicator;
determining that another substantive change in the physiologic monitoring data occurred;
interrogating the MPO sensor to determine if there was a position change of the patient; and
based on determining that there was the position change of the patient resulting in corrupted physiologic monitoring data, pausing the caregiver feedback until the patient motion abates.

2. The method of claim 1 , further comprising:
receiving information indicative of a temperature at the sensor; and
based on determining that the temperature at the sensor is above a threshold temperature, generating, for the physiologic monitoring data, the respective quality indicator.

3. The method of claim 1 , further comprising:
receiving information indicative of ambient light at the sensor; and
based on determining that ambient light at the sensor is above a threshold light, generating, for the physiologic monitoring data, the respective quality indicator.

4. The method of claim 1 , further comprising:
sending, by the computing device, a wireless signal to the sensor interrogating the sensor for data; and
in response, receiving the physiologic monitoring data from the sensor.

5. The method of claim 1 , further comprising:
based on determining that there was the position change of the patient, discarding or ignoring the corrupted physiologic monitoring data that occurred.

6. The method of claim 1 , wherein receiving the physiologic monitoring data comprises receiving the physiologic monitoring data from a plurality of sensors by:
receiving, from a camera, images indicative of placement of a tube for intubation in the patient;
receiving, from a carbon dioxide detector, an indication of carbon dioxide expelled by the patient;
receiving, from a microphone, an indication of sounds in the tube; and
receiving, from a gas detector, an indication of presence of gases in the tube; and
the method further comprising:
based on a combination of the physiologic monitoring data from the plurality of sensors and a respective quality indicator for each of the physiologic monitoring data, outputting the caregiver feedback by the computing device indicative of whether the tube is properly placed in the patient and whether the tube has moved out of place since installation.

7. The method of claim 1 , wherein receiving the physiologic monitoring data comprises receiving the physiologic monitoring data from a plurality of sensors by:
receiving, from a pressure sensor, an indication of airflow pressure in a tube for intubation in the patient;
receiving, from an air flow sensor, an indication of airflow in the tube; and
receiving, from a pulse oximetry sensor, a measure of blood oxygenation in the patient;
the method further comprising:
based on a combination of the physiologic monitoring data from the plurality of sensors and a respective quality indicator for each of the physiologic monitoring data, outputting the caregiver feedback by the computing device indicative of one or more of: whether an airway of the patient is over pressurized, whether a volume of air is too high and patient oxygenation is too high, whether the volume of air is too low and the patient oxygenation is inadequate, and spontaneous breathing.

8. The method of claim 1 , wherein receiving the physiologic monitoring data comprises receiving the physiologic monitoring data from a plurality of sensors by:
receiving, from a pressure sensor, an indication of airflow pressure in a tube for intubation in the patient;
receiving, from an air flow sensor, an indication of airflow in the tube;
receiving, from a carbon dioxide sensor, an indication of carbon dioxide expelled by the patient; and
receiving, from an oxygen sensor, an indication of oxygen inhaled by the patient;
the method further comprising:
based on a combination of the physiologic monitoring data from the plurality of sensors and a respective quality indicator for each of the physiologic monitoring data, outputting the caregiver feedback by the computing device indicative of one or more of: whether cardiopulmonary resuscitation (CPR) appears to sustain targeted or expected levels of expired carbon dioxide, and re-evaluation of (i) hand placement on the patient, (ii) depth of compression, (iii) rate of compression, or (iv) recoil.

9. The method of claim 1 , wherein receiving the physiologic monitoring data comprises receiving the physiologic monitoring data from a plurality of sensors by:
receiving, from a metabolic sensor, an indication of a metabolic rate of the patient;
receiving, from a blood pressure sensor, an indication of a blood pressure of the patient;
receiving, from a depth sensor, an indication of a depth of compression applied during cardiopulmonary resuscitation (CPR); and
receiving, from an ultrasound sensor, an indication of vessel area and flow profile over time;
the method further comprising:
based on a combination of the physiologic monitoring data from the plurality of sensors and a respective quality indicator for each of the physiologic monitoring data, outputting the caregiver feedback by the computing device indicative of one or more of: whether CPR appears to be moving a sufficient amount of oxygenated blood, and re-evaluation of (i) hand placement on the patient, (ii) depth of compression, (iii) rate of compression, or (iv) recoil.

10. The method of claim 1 , wherein receiving the physiologic monitoring data comprises receiving the physiologic monitoring data from a plurality of sensors by:
receiving, from external pressure sensors, tactile pressure applied to a chest of a patient during cardiopulmonary resuscitation (CPR); and
receiving, from external ultrasound sensors, an indication of a location of a heart of the patient;
the method further comprising:
based on a combination of the physiologic monitoring data from the plurality of sensors and a respective quality indicator for each of the physiologic monitoring data, outputting the caregiver feedback by the computing device indicative of whether hand placement for CPR needs to be adjusted.

11. The method of claim 1 , wherein the threshold for motion varies based on a type of physiological monitoring data.

12. The method of claim 1 , further comprising:
generating one or more context indicators displayed in conjunction with a display of the physiologic monitoring data, wherein the one or more context indicators graphically convey an amount of motion exhibited by the patient.

13. The method of claim 1 , wherein the information indicating the measurement of patient motion includes information of motion, orientation, or position of a part or a whole of a body of the patient during the patient care event, and the method further comprises:
generating one or mor
