Issues And Trends In Healthcare Delivery System01:29

Issues And Trends In Healthcare Delivery System

The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.
Cost Containment
Payment for healthcare services has historically promoted adoption of costly and often unnecessary or inefficient...
Current Trends in Nursing II01:30

Current Trends in Nursing II

Trends in nursing are multifactorial and associated with changes in society, within the nursing profession, and in other professions. Notably, telehealth and remote nursing contribute to successful healthcare delivery for numerous patients and help reduce stress for nurses due to nursing shortages. Nurses can reach patients, monitor their conditions, and interact with them using computers, audio, visual accessories, and telephones—for example, remote patient monitoring systems. Likewise,...
Design Example01:23

Design Example

The innovation of touch-tone telephony revolutionized the telecommunications industry by replacing the traditional rotary dial with a dual-tone multi-frequency (DTMF) signaling system. This system uses a matrix-style keypad with buttons arranged in four rows and three columns, creating 12 distinct signals each assigned to a pair of frequencies. Each button press results in a simultaneous generation of two sinusoidal tones – one from a low-frequency group (697 to 941 Hz) and one from a...
Barriers to Effective Communication II01:21

Barriers to Effective Communication II

The barriers to effective communication also include cultural barriers, semantic barriers, gender barriers, and time constraints.
Cultural barriers:
Differences in values, beliefs, religion, knowledge, and tradition can significantly impact communication. Awareness of nonverbal cues is critical, especially when conversing with a patient from a different culture. What appears appropriate in one culture may be inappropriate in another.
Semantic barriers:
As a result of their tendency to use...
Ethical Issues01:27

Ethical Issues

Nurses are essential in patient care, upholding the ethical principles of their profession and effectively navigating ethical dilemmas. Neglecting ethical issues can lead to inadequate patient care, compromised therapeutic relationships, and moral distress among healthcare workers.

Interference: Path Lengths01:10

Interference: Path Lengths

Consider two sources of sound, that may or may not be in phase, emitting waves at a single frequency, and consider the frequencies to be the same.
Two special sources may be considered when they are in phase. This can be easily achieved by feeding the two sources from the same source. An example would be synchronizing the two speakers by feeding them with the same source, such as the sound waves produced by a tuning fork. This setup ensures that the two sources have the same frequency and are...

Area of Science:

  • Biomedical Engineering
  • Wireless Communication Systems
  • Medical Informatics

Background:

  • Wireless technologies are crucial for personal area networks (PAN) in telemedicine.
  • Multiple wireless technologies, often in the 2.4-GHz band, must coexist.
  • Existing interference mitigation mechanisms in standards may not perform as expected in real-world scenarios.

Purpose of the Study:

  • To experimentally evaluate the coexistence and interference of Bluetooth (ECG), Zigbee (temperature sensors), and WiFi in a telemedicine context.
  • To assess the performance of continuous and discrete medical signal transmission under mixed wireless environments.
  • To provide practical recommendations for reliable operation of these wireless technologies in medical applications.

Main Methods:

  • Implementation of a real-world experimental setup involving Bluetooth-based ECG, Zigbee temperature sensors, and a WiFi network.
  • Simultaneous operation and data collection from all three wireless technologies.
  • Analysis of signal interference and performance impact on medical data transmission.

Main Results:

  • Demonstrated real-world interference issues between Bluetooth, Zigbee, and WiFi operating in close proximity.
  • Observed deviations from theoretical performance of standard interference mitigation mechanisms.
  • Quantified the impact of interference on the reliability of continuous (ECG) and discrete (temperature) medical signal transmission.

Conclusions:

  • Coexistence of Bluetooth, Zigbee, and WiFi in telemedicine PANs presents significant interference challenges.
  • Standard interference handling may be insufficient, necessitating careful system design and deployment strategies.
  • Recommendations are provided for optimizing the reliable operation of these wireless technologies for medical applications.
