Blood pressure is the force exerted by blood on vessel walls as the heart pumps and relaxes. Systolic pressure occurs when the heart contracts while diastolic pressure is when the heart relaxes. Blood pressure ensures blood flow to organs and facilitates gas/nutrient exchange and urine/lymph formation. Common types include normal, high (hypertension), and low (hypotension) blood pressure. Blood pressure is measured non-invasively with devices and following guidelines around patient position and state. Factors like stress, diet, exercise impact blood pressure, which baroreceptor and chemoreceptor reflexes along with the renin-angiotensin system help regulate.

Blood pressure is measured by a sphygmomanometer and stethoscope. It involves two readings: systolic (top number) which is the pressure when the heart contracts, and diastolic (bottom number) which is the pressure when the heart relaxes. Sounds known as Korotkoff sounds are used to determine these readings as the cuff is deflated. Blood pressure is written as the systolic over the diastolic pressure in mmHg and is influenced by factors like age, stress, and medications. Abnormal blood pressures include hypertension (high) and hypotension (low).

Blood pressure is the force exerted by blood on the walls of arteries and is measured in millimeters of mercury (mmHg). It is written as the systolic pressure over the diastolic pressure. The systolic pressure occurs when the heart contracts while the diastolic pressure occurs when the heart is at rest between beats. Blood pressure is dependent on factors like cardiac output, peripheral resistance, blood viscosity, and blood volume. It can be measured using a sphygmomanometer and listening for Korotkoff sounds over the brachial artery. Oxygen saturation measures the percentage of hemoglobin binding sites occupied by oxygen and is measured noninvasively using a pulse oximeter.
Hemodynamics and Shock
Hemodynamic monitoring involves measuring and monitoring the factors that influence blood flow and pressure in the body. It is concerned with five main areas: the right heart, lungs, left heart, fluid status, and blood pressures. Normal hemodynamic values include a central venous pressure of 2-6 mmHg, pulmonary artery pressure of 6-15 mmHg, pulmonary capillary wedge pressure of 6-12 mmHg, and a cardiac output of 4-8 L/min. Treatment for different types of shock depends on the underlying cause but may include inotropes, vasopressors, antibiotics, and fluid resuscitation.

Methods to screen blood pressure
Methods to screen Blood Pressure outlines various methods for measuring blood pressure, including direct and indirect techniques. Indirect techniques include palpatory and auscultatory methods using a sphygmomanometer. The auscultatory method, developed by Korotkoff, involves listening with a stethoscope over the brachial artery as the cuff is deflated to determine systolic and diastolic pressures. Normal blood pressure ranges from 100/60 to 140/80 mmHg, with systolic pressure reflecting heart contraction and diastolic reflecting vessel relaxation between beats.
Blood pressure and its regulation .
Blood pressure is regulated through both short-term and long-term mechanisms. Short-term regulation involves neural mechanisms like the autonomic nervous system and baroreceptor reflexes which sense changes in blood pressure and heart rate. It also involves vascular mechanisms like changes in capillary fluid and stress relaxation as well as hormonal mechanisms like catecholamines and renin-angiotensin system. Long-term regulation is controlled by the kidneys and renal mechanisms as well as hormones like aldosterone, ADH, ANP and the renin-angiotensin-aldosterone system. Together these mechanisms tightly control blood pressure and ensure adequate perfusion to tissues.

The document provides information on measuring blood pressure, including:
- Defining systolic and diastolic blood pressure as the pressure when the heart contracts and relaxes. Normal ranges are less than 120/80 mmHg.
- Explaining methods of measurement, including using a sphygmomanometer and stethoscope on the brachial artery. Factors that can affect readings are also discussed."
Arterial blood pressure
Normal arterial blood pressure ranges from 90-140/60-90 mmHg. Systolic pressure is the maximum pressure when blood is ejected from the heart, while diastolic is the minimum pressure when the heart is resting between beats. Mean arterial pressure, which averages 93 mmHg, is the main driving force for blood flow. Blood pressure is regulated through short term mechanisms like baroreceptor and chemoreceptor reflexes which control heart rate and vascular tone, and long term factors like blood volume and vessel elasticity. Strict control of blood pressure is important to ensure adequate blood flow to vital organs.
Haemodynamic monitoring during cpb

It describes how components such as heart rate, blood pressure, cardiac output, stroke volume, central venous pressure and pulmonary artery pressures are measured and used to establish baseline values, evaluate trends, determine dysfunction, and guide interventions. Factors that influence hemodynamics like preload, afterload, contractility and resistance are also explained. Normal ranges for various measurement values are provided.
Physical characteristics of systemic circulation
The document discusses various physical characteristics of the systemic circulation including cross-sectional area, pressure, resistance, blood flow, and vascular compliance and distensibility. It provides details on blood pressure, pulse pressure, factors affecting venous return, vascular resistance according to Ohm's law, and the distensibility and compliance of arteries and veins.
Determinants of cardiac output for captivate
This document discusses determinants of cardiac output and factors that influence heart function. Cardiac output is determined by heart rate and stroke volume. Stroke volume depends on preload, afterload and contractility. Preload refers to ventricular filling, afterload is the resistance against which the heart pumps, and contractility is the heart's inherent ability to contract. Conditions such as heart failure, shock and arrhythmias can decrease cardiac output by impacting these determinants. Understanding hemodynamics helps evaluate a patient's cardiac function and guide treatment.
Blood pressure
Blood pressure is the pressure exerted by circulating blood on the walls of blood vessels. It is typically measured in millimeters of mercury (mmHg). Normal blood pressure is less than 120/80 mmHg. Blood pressure is regulated through both immediate mechanisms like baroreceptor reflexes and delayed mechanisms involving the kidneys, renin-angiotensin system, and other hormones. Factors that affect blood pressure include cardiac output, peripheral resistance, blood volume, vessel elasticity, and viscosity. Hypertension is defined as high blood pressure over 140/90 mmHg and can increase the risk of heart disease and stroke if left untreated.

This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

BP FOR BCVT.pptx
- 2. DEFINITION Arterial blood pressure is the force exerted by the blood on the wall of a blood vessel as the heart pumps (contracts) and relaxes. Systolic blood pressure is the degree of force when the heart is pumping (contracting). The diastolic blood pressure is the degree of force when the hearts relaxed.
- 3. SIGNIFICANCE To ensure the blood flow to various organs. Plays an important role in exchange of gases and nutrients across capillaries. Required to form urine. Required for the formation of the lymph.
- 4. SYSTOLIC BP Defined as the maximum B.P in the arteries attainable during systole. It is contributed by Blood volume, cardiac output and force of heart beat.
- 5. DIASTOLIC BP,MAP ,PP Defined as the minimum pressure that is obtained at the end of the ventricular diastole. It is the index to the peripheral resistance and decides the filling of the coronary system. PULSE PRESSURE = SBP - DBP MAP = DBP + 1/3 PP
- 9. • White-coat hypertension - BP is elevated in the office, but is normal when measured by ABPM,HBPM, or both. • Masked hypertension - refers to untreated patients in whom the BP is normal in the office, but is elevated when measured by HBPM or ABPM. • True normotension - is used when both office and out-of-office BP measurements are normal • Sustained hypertension - is used when both are abnormal
- 10. Hypotension Postural hypotension – SBP drop > 15 mm hg immedialtely standing from supine position
- 11. HOW TO MEAUSURE BLOOD PRESSURE TECHNIQUE – INVASIVE NON INVASIVE Which arm – RT /LT ARM ( difference should not be > 10 mm hg SBP & >5 DBP POSITION – SUPINE ,SITTING ( ARM SHOULD BE AT THE LEVEL OF HEART ) PATIENT – RELAXED,SHOULD NOT TAKE COFFEE /SMOKING/EXERCISE/STRESS TIGHT CLOTHIG /DISTENDEDBLADDER
- 12. STEPHEN HALES – DEMO OF 1st BP Measurement
- 16. KORTOKOFF SOUNDS These sounds represent arterial oscillations from distension of arterial wall with each cardiac impulse due to partial occlusion of artery by blood pressure cuff
- 18. FACTORS AFFECTING THE BLOOD PRESSURE
- 22. REGULATION OF BLOOD PRESSURE A) IMMEDIATE MECHANISM- - Neural mechanisms: 1) BARORECEPTOR REFLEXES. 2) CHEMORECEPTOR REFLEXES. 3) CEREBRAL ISCHEMIC RESPONSE.
- 27. NET EFFECT- INCREASED BP, INCREASED HEART RATE.
- 31. Action of Angiotensin II Vasoconstriction Secretion of Aldosterone. Stimulation of thirst centre. Increased absorption of sodium from PCT by direct effect. Blood volume increases, CO increases, BP increases.
