Pressure of Fluids01:14

Pressure of Fluids

15.8K
There are many examples of pressure in fluids in everyday life, such as in relation to blood (high or low blood pressure) and in relation to weather (high- and low-pressure weather systems). A given force can have a significantly different effect, depending on the area over which the force is exerted. For instance, a force applied to an area of 1 mm2 has a pressure that is 100 times greater than the same force applied to an area of 1 cm2. That's why a sharp needle is able to poke through...

Fluid Pressure01:14

Fluid Pressure

590
In mechanical engineering, fluid pressure plays a critical role in designing systems that utilize liquid flow, such as hydraulic systems, pumps, and valves. When designing these systems, engineers must ensure they can withstand the forces created by fluid pressure to avoid damage or failure.
According to Pascal's law, a fluid at rest will generate equal pressure in all directions. This pressure is measured as a force per unit area, and its magnitude depends on the fluid's specific...

Pressure Gauges01:20

Pressure Gauges

3.4K
Most pressure gauges, like those on scuba tanks, are calibrated to read zero at atmospheric pressure. Readings from such gauges are called the gauge pressure, which is the pressure relative to atmospheric pressure. When the pressure inside the tank exceeds atmospheric pressure, the gauge reports a positive value. Some gauges are designed to measure negative pressure. For example, many physics experiments must take place in a vacuum chamber, a rigid chamber from which some of the air is pumped...

Concept of Pressure at a Point01:15

Concept of Pressure at a Point

228
The concept of pressure at a point in a fluid establishes that pressure within a fluid is uniform in all directions at a specific location. This uniformity occurs because fluid molecules exert force evenly across any point due to their random motion and continuous collisions within the fluid. Pressure at a point is determined by the surrounding fluid molecules and is influenced by factors like depth and density, rather than by shape or orientation.
In a fluid at rest, pressure acts equally in...

Application of Pascal's Law

8.4K
Pascal's experimentally proven observations—that a change in pressure applied to an enclosed fluid is transmitted undiminished throughout the fluid and to the walls of its container—provide the foundations for hydraulics, one of the most important developments in modern mechanical technology.
Hydraulic systems are used to operate automotive brakes, hydraulic jacks, and numerous other mechanical systems. We can derive a relationship between the forces in a simple hydraulic system...

Pascal's Law01:04

Pascal's Law

8.4K
In 1653, the French philosopher and scientist Blaise Pascal published "Treatise on the Equilibrium of Liquids," which discussed the principles of static fluids. A static fluid is a fluid that is not in motion. When a fluid is not flowing, we say that the fluid is in static equilibrium. If the fluid is water, we say it is in hydrostatic equilibrium. For a fluid in static equilibrium, the net force on any part of the fluid must be zero; otherwise, the fluid will start to flow. Pascal...

Area of Science:

  • Cardiology
  • Public Health
  • Health Communication

Background:

  • Cardiovascular disease (CVD) risk factor control is crucial for healthy ageing.
  • Effective communication and shared decision-making between healthcare professionals (HCPs) and patients are vital for managing CVD risk.
  • Patient motivation can be enhanced through age-based approaches and personalized risk feedback.

Purpose of the Study:

  • To develop and pilot a scalable model for engaging patients on the benefits of risk factor control for healthy ageing.
  • To train HCPs in CVD risk communication and patient engagement strategies.
  • To improve shared decision-making processes regarding CVD risk management.

Main Methods:

  • Utilized the 'Heart Age' CVD risk tool to motivate risk factor reduction.
  • Engaged patients and HCPs virtually through community, third sector, charities, and social media.
  • Conducted online focus groups and surveys with patients experiencing hypertension to gather preferences for risk communication and intervention benefits.
  • Adapted the 'Heart Age' tool based on patient feedback to highlight 'years off' benefits from blood pressure lowering.
  • Piloted a training program for nurses and pharmacists on risk communication and framing intervention benefits.

Main Results:

  • Trained 1,148 HCPs from 37 countries across 17 sessions.
  • Post-training surveys showed increased HCP self-rated knowledge and high likelihood of applying learned information.
  • HCPs reported that the 'Heart Age' tool and personalized reports were highly motivating for patients with high blood pressure.
  • Patient insights informed adaptations to the 'Heart Age' tool, focusing on medication and lifestyle benefits for blood pressure reduction.

Conclusions:

  • The 'Share The Pressure' project successfully developed and piloted a model for enhanced CVD risk communication and patient engagement.
  • Training HCPs and adapting risk communication tools can improve shared decision-making and motivate patients towards healthy ageing.
  • The 'Heart Age' tool, particularly with personalized feedback on blood pressure management, is a valuable resource for motivating patients.
