Pilot and Numeric Relaying01:21

Pilot and Numeric Relaying

496
Pilot relaying is a type of differential protection used in power systems. It compares electrical quantities at the terminals of equipment via a communication channel instead of direct relay interconnection. This method is essential for transmission lines where the terminals are far apart, typically up to 80 km for lines with 69 to 115 kV ratings. Four types of communication channels are used for pilot relaying:

Hypertension I: Introduction01:28

Hypertension I: Introduction

953
Hypertension is a widespread, long-term medical condition where blood pressure in the arteries remains elevated. It is characterized by systolic blood pressure readings of 130 mm Hg or above or diastolic blood pressure (DBP) readings of 80 mm Hg or higher. Unmanaged hypertension poses significant health risks, making the distinction between primary (or essential) hypertension and secondary hypertension crucial, as their management and implications vary.Primary HypertensionPrimary hypertension,...

Hypertension II: Pathophysiology

1.0K
Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...

Hypertension V: Nursing Management

482
The nursing management of hypertension involves accurately assessing symptoms, making a comprehensive nursing diagnosis, collaborating with patients to set goals, and implementing targeted interventions to mitigate the condition's impact and improve patient well-being.Comprehensive AssessmentThe initial step in nursing care for hypertension involves a thorough patient assessment. It includes evaluating symptoms such as headaches, dizziness, blurred vision, and previous hypertension episodes.

Area of Science:

  • Cardiovascular Medicine
  • Neurology
  • Digital Health

Background:

  • Hypertension (HTN) management is often suboptimal in post-stroke patients.
  • Effective strategies are needed to improve adherence and control in this population.

Purpose of the Study:

  • To evaluate the usability and efficacy of a mobile health (mHealth)-based care model for enhancing hypertension control in stroke survivors.
  • To assess the impact of a technology-assisted intervention on blood pressure management post-stroke.

Main Methods:

  • A randomized controlled trial (RCT) design was employed over 90 days.
  • The intervention arm (IA) involved daily BP monitoring via smartphone and automated data transmission, with bi-weekly medication adjustments by clinicians.
  • The control arm (CA) received a digital BP monitor and standard care. Usability was assessed using the Marshfield System Usability Survey.

Main Results:

  • Participants using the mHealth model (IA) showed a significant decline in systolic blood pressure (SBP): 9.88 mm Hg (p=0.005) in intent-to-treat (ITT) analysis and 10.81 mm Hg (p=0.0036) in as-treated (AT) analysis.
  • Hypertension control rates were higher in the IA: 82% (ITT) and 89% (AT) compared to the CA (64% ITT, 58% AT).
  • The mHealth system achieved a usability score of 4.6 out of 5, indicating ease of use.

Conclusions:

  • The mHealth-based hypertension care model is highly usable and effective for improving blood pressure control in stroke survivors.
  • This digital health approach offers a promising alternative to usual care for managing hypertension in this vulnerable patient group.
