Medical procedures are structured actions performed by healthcare professionals to diagnose, treat, or monitor patients' health conditions. They range from non-invasive diagnostics to complex surgical interventions, each requiring specific protocols, skills, and equipment to ensure patient safety and efficacy.

Flow rate is a measure of the volume of fluid that passes through a point or a surface per unit time, often expressed in units such as liters per second or cubic meters per hour. It is a critical parameter in fluid dynamics, engineering, and various industrial applications, influencing system design and efficiency.

Flow Rate

Pressure is the force exerted per unit area on the surface of an object, which can arise from various sources such as gases, liquids, or solids. It plays a crucial role in numerous scientific and engineering applications, influencing phenomena ranging from weather patterns to the behavior of gases and liquids in different environments.

Pressure

Tissue trauma refers to damage caused to biological tissues, which can result from mechanical, thermal, chemical, or biological agents, leading to varying degrees of cellular disruption and inflammation. Understanding the mechanisms of tissue trauma is crucial for developing effective treatments and preventing complications such as infection and impaired healing.
