Pulse rhythm01:30

Pulse rhythm

900
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...

Introduction to Vital Signs01:25

Introduction to Vital Signs

2.8K
Vital signs are physiological measurements that help key into the status of the body's essential functions. These include body temperature, pulse rate, respiratory rate, and blood pressure, commonly abbreviated as T, P, R, and BP. Some healthcare settings also consider oxygen saturation (SpO2) and, in specific contexts, pain and level of consciousness as additional vital signs.
Vital signs help healthcare professionals assess an individual's well-being and detect any functional changes...

Guidelines For Measuring Vital Signs01:19

Guidelines For Measuring Vital Signs

1.9K
Following these guidelines can help nurses accurately measure vital signs, assess changes in patient conditions, and provide timely treatment when necessary. Adhering closely to the guidelines ensures the accuracy and reliability of the results.
Before taking a patient's vital signs, a nurse would consider and assess the patient's comfort level and ensure appropriate equipment is available.

Holter Monitor: 24-Hour Monitoring01:23

Holter Monitor: 24-Hour Monitoring

196
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...

Main Results:

  • Successfully converted vital signs (blood pressure, heart rate, respiratory rate, body temperature) from electronic health records into FHIR observations (JSON format).
  • Extracted and stored electronic health record information on a FHIR server.
  • Integrated multiple systems (early warning, machine learning) via FHIR RESTful API into a unified dashboard.

Conclusions:

  • Demonstrated a standardized process for using vital signs to detect inpatient deterioration.
  • Provided a FHIR-based implementation guide for IHCA assessment, including data mapping and integration.
  • Developed a clarifying system architecture and workflows that simplify medical staff interaction with complex integrated systems.
