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...

Holter Monitor: 24-Hour Monitoring

Holter Monitor: 24-Hour Monitoring

Holter monitoring is a continuous electrocardiography (ECG) recording that tracks the heart's electrical activity over an extended period, generally 24 to 48 hours. This noninvasive diagnostic tool detects irregular heart rhythms that may not be captured during a standard ECG performed in a clinical setting.DeviceThe Holter monitor is a portable, small device connected to several electrodes on the patient's chest. These electrodes detect the heart's electrical signals and transmit them to the...

Background:

Previous research indicated configural displays reduce reaction time to emergency events compared to numeric displays.
Configural displays map vital sign variables in a two-dimensional space for intuitive understanding.

Purpose of the Study:

To compare the effects of numeric and configural visual displays on reaction time, accuracy, and workload.
To investigate how display position and eccentricity influence multitasking performance in a simulated patient monitoring task.

Main Methods:

Thirty participants performed a simulated patient monitoring task with concurrent numeric and configural displays.
Reaction time and accuracy were measured for primary and secondary (N-Back) tasks.
Workload was assessed using pupillometry and NASA-TLX self-reports.

Main Results:

Configural display position (right, near center) and low eccentricity improved secondary task performance (reaction time, accuracy).
Pupil dilation increased during emergencies, and NASA-TLX scores rose with greater display eccentricity.
Participants reported high mental but low physical demand.

Conclusions:

Display configuration significantly impacts multitasking performance and workload.
Right-positioned, low-eccentricity configural displays may enhance multitasking in clinical settings.
Interface design should consider spatial arrangement and eccentricity for optimal user efficiency.
