Data

Below are links to some examples of data recorded during our research projects and used in our publications.

Detection Benchmarks

• Intracranial Pressure, Blood Pressure, and Pulse Oximetry (infrared) Beat Detection Benchmarks. Each file has two signal segments from two different patients (e.g. icp1, icp2), the detected indices of the systolic peaks as detected by the algorithm (i.e., d1, d2) and the systolic peaks as visually detected by three experts (dDT1 dDT2 dJM1 dJM2 dTT1 dTT2). The sample rate of all the signals was 125 Hz. The heart rate in these signals may be higher than expected because these signals were acquired from children in a pediatric intensive care unit. Additional details are in the journal article describing the detection algorithm.

Noisy Electrocardiogram

• Electrocardiogram:  signal recorded at 500 Hz sampling rate from a pediatric head injury patient. This segment is contains a lot of noise and a drop-out typical of data recorded in an intensive care unit setting.

Traumatic Brain Injury Data

The following data was all recorded during a 6 hour period simultaneously from a single pediatric patient with a traumatic brain injury.

• Electrocardiogram: zipped text file, sampled at 500 Hz, units unknown.

• Arterial Blood Pressure: zipped text file, sampled at 125 Hz in units of mmHg.
  (Zipped)
• Central Venous Pressure: zipped text file, sampled at 125 Hz in units of mmHg. Contains two drop outs.

• Intracranial Pressure: zipped text file, sampled at 125 Hz in units of mmHg.
  (Zipped)
• Respiration: zipped text file, sampled at 125 Hz, units are scaled to range from 0 to 1023.

• Pulse Oxymetry: one of the two signals from a pulse oximeter sampled at 125 Hz, units are scaled to range from 0 to 1023.
