Pulse rhythm

Pulse rhythm

Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac...

Area of Science:

Medical Imaging Technology
Healthcare Systems Engineering
Wearable Sensor Applications

Background:

Manual scheduling of Positron Emission Tomography (PET) scans is prone to errors due to high patient volume and frequent schedule changes.
Existing research lacks comprehensive solutions for optimizing the overall PET scanning process.
Inefficient scheduling leads to increased patient wait times, staff pressure, and logistical challenges.

Purpose of the Study:

To develop and evaluate a real-time automatic scheduling and control system for PET patients.
To improve the time efficiency and accuracy of PET scan scheduling.
To reduce the burden on medical staff and enhance the patient experience.

Main Methods:

Implementation of a novel system integrating wearable sensors for real-time data collection.
Automatic scheduling, task time estimation, bed allocation, and real-time announcement of schedule information.
Simulation and comparison using time data from 200 actual patients.

Main Results:

The automated system demonstrated an average time difference of 7.32 minutes compared to manual scheduling.
It reduced the average examination time for 82% of patients by 6.14 ± 4.61 minutes.
The system proved effective in improving time efficiency and reducing human error.

Conclusions:

The proposed real-time automatic scheduling system enhances PET scan workflow efficiency.
It successfully mitigates human error, alleviates staff pressure, and improves patient satisfaction.
This technology offers a significant advancement in managing PET imaging logistics.
