This document provides an overview of oxygenation, respiration, and the cardiovascular system. It defines key terms related to oxygenation and discusses the mechanisms of respiration and the cardiovascular system. Factors that can affect oxygenation are explained. Common manifestations of altered respiratory and cardiovascular function include hypoxia, altered breathing patterns, decreased cardiac output, and impaired tissue perfusion. Nursing measures to ensure patient airway and emergencies related to the respiratory and cardiovascular systems are also outlined. The document concludes by differentiating between medical and surgical asepsis.
This document provides information on oxygen insufficiency and discusses key points:
- Oxygen is essential for life and is involved in cellular respiration. It makes up 20.94% of air by volume.
- Oxygen insufficiency, or hypoxia, occurs when oxygen delivery to tissues is inadequate to meet metabolic demands. This can be caused by problems with ventilation, gas exchange, oxygen transport, or cellular respiration.
- Symptoms of hypoxia range from shortness of breath to confusion and loss of consciousness. Diagnostic tests for hypoxia include blood gas analysis, pulse oximetry, pulmonary function tests, and imaging studies.
- Nursing management of patients with oxygen insufficiency focuses on
Shock is defined as inadequate tissue perfusion due to decreased oxygen delivery or utilization leading to cellular hypoxia. It is a life-threatening condition characterized by circulatory failure and hypotension. There are four main types of shock: distributive, hypovolemic, cardiogenic, and obstructive. Septic shock, a form of distributive shock, results from a dysregulated immune response to infection leading to vasodilation and hypotension. Management of septic shock involves fluid resuscitation, vasopressor support, antibiotic treatment, and control of the underlying infection. The pathophysiology is complex, involving an interplay between the immune system, inflammatory response, and cardiovascular system.
This document discusses shock, including its pathophysiology, classification, clinical features, consequences, and resuscitation. Shock is defined as inadequate tissue perfusion resulting in cellular changes from aerobic to anaerobic metabolism. The main types of shock are hypovolemic, cardiogenic, obstructive, distributive, and endocrine. Left untreated, shock can lead to multiple organ failure and death. Initial resuscitation focuses on airway, breathing, and restoring circulating volume through fluid administration. Ongoing monitoring and support of vital organs is needed until the underlying cause is addressed.
Shock is a state of low tissue perfusion that prevents normal cellular respiration. There are several classifications of shock including hypovolaemic, cardiogenic, obstructive, distributive, and endocrine shock. The key goals of resuscitation are to ensure adequate oxygenation, ventilation, and cardiovascular support through fluid administration and vasopressors if needed. Ongoing monitoring of vital signs, urine output, and markers of tissue perfusion like lactate levels are important to guide resuscitation efforts and avoid complications like multiple organ failure.
The Pulmonary system - Artificial organ 2.pptxHusseinMishbak
The pulmonary system, also known as the respiratory system, allows us to breathe by bringing oxygen into the body and removing carbon dioxide. It includes the lungs, airways, blood vessels, and respiratory muscles. The lungs contain millions of alveoli where gas exchange occurs between the blood and air. Lung diseases such as asthma, COPD, and lung cancer can damage the lungs and impair their ability to oxygenate the blood and remove carbon dioxide, potentially leading to hypoxia, hypercapnia, and other health issues. Lung transplantation and artificial lungs can provide life-saving treatment for patients with end-stage lung disease.
The document discusses acute respiratory failure, defined as insufficient oxygen and elevated carbon dioxide levels in the blood, and describes its two main types: hypoxemic respiratory failure characterized by low oxygen levels, and hypercapnic respiratory failure characterized by high carbon dioxide levels. It examines the causes, clinical features, diagnosis, and treatment of each type of acute respiratory failure.
This document discusses respiratory failure, including its causes, types, and management. Respiratory failure occurs when inadequate gas exchange prevents normal oxygen and carbon dioxide levels in the blood. It can result from conditions affecting breathing muscles/nerves or lung tissue damage. The two main types are hypoxemic respiratory failure, where oxygen levels are too low, and hypercapnic respiratory failure, where carbon dioxide levels are too high. Management involves oxygen therapy, positioning, clearing secretions, and potentially positive pressure ventilation.
Pathophysiology: Introduction to Circulatory and Respiratory SystemHannahLeopard1
1) Pathophysiology is the study of how disease processes affect the normal functioning of the body. It explains abnormalities in cells, tissues, and organ systems.
2) The cardiopulmonary system relies on adequate oxygen delivery to cells through blood perfusion. Disruptions in perfusion can cause hypoperfusion and shock.
3) Metabolism is the process by which the body converts food to energy. Aerobic metabolism uses oxygen efficiently while anaerobic metabolism is less efficient and can cause problems without enough oxygen.

cardiac output measurment and monitoring ppt-1.pptxshekinah41
Cardiac output monitoring provides essential information about heart function and tissue perfusion. There are various methods of monitoring cardiac output, ranging from non-invasive to invasive. The pulmonary artery catheter, which involves thermodilution, has long been the gold standard but is invasive. Less invasive methods like lithium dilution and pulse contour analysis are also used. The ideal method would be non-invasive, accurate, continuous and reproducible across patients, but no single technique currently meets all these criteria.

FN 513 SIMARPREET KAUR,RESPIRATION MECHANISM AND REGULATION.pptxSimarpreetKaur311857
The document discusses respiration and its various mechanisms and regulatory processes. It describes that respiration involves the movement of oxygen from the environment to cells and carbon dioxide in the opposite direction. This occurs through two main processes: breathing and gas exchange. It details the steps in respiration including breathing, gas diffusion between alveoli and blood, transport of gases, gas diffusion between blood and tissues, and utilization of oxygen. It discusses the roles of muscles in inspiration and expiration. It also outlines respiratory volumes, capacities, the exchange and transport of gases, and the regulation of respiration through the respiratory center and chemoreceptors.
This document provides an overview of respiratory physiology and acute respiratory failure. It discusses:
1. The functions of the respiratory system including gas exchange, acid-base balance, phonation, pulmonary defense, and metabolism.
2. The three components of respiration - ventilation, gas exchange, and oxygen utilization. It describes the mechanics of ventilation and gas exchange via diffusion.
3. The conducting and respiratory zones of the lungs and structures involved in gas exchange like alveoli and surfactant.
4. Control of respiration via brainstem centers that regulate rhythmic breathing and chemoreceptors that sense blood gases and pH to modulate breathing rate and depth.

Factors that influence lung compliance, elasticity, and surface tension are also reviewed.
The ventilatory and cardiovascular systems work together to increase oxygen delivery during exercise in order to maintain homeostasis. The ventilatory system increases breathing rate and volume through actions of the diaphragm and intercostal muscles. The cardiovascular system increases cardiac output through higher heart rate and stroke volume to distribute more blood to working muscles. Both systems must precisely coordinate their responses to exercise in order to meet increased demand for oxygen while removing carbon dioxide.
This document discusses hemodynamic disorders including thromboembolic disease and shock. It defines shock and classifies it into four main types: hypovolemic, cardiogenic, septic, and traumatic shock. The pathogenesis of each type is described. Morphologic features in organs during shock like the brain, heart, lungs, kidneys, adrenals, gastrointestinal tract, and liver are outlined. The clinical features and complications of shock are also summarized.
Shock is a life-threatening condition caused by inadequate tissue perfusion. It has several stages from initial to irreversible. The main types are hypovolemic, cardiogenic, obstructive, distributive, and neurogenic. Hypovolemic shock results from a loss of intravascular volume and is the most common type. Diagnosis involves assessing vital signs and fluid status. Treatment focuses on restoring volume with fluids and blood products, addressing the underlying cause, and supporting organ function. Close monitoring for complications is important during resuscitation.
ARDS means acute respiratory distress syndrome. It is a respiratory disorder. Acute respiratory distress syndrome (ARDS) occurs when fluid builds up in the tiny, elastic air sacs (alveoli) in your lungs. The fluid keeps the lungs from filling with enough air, which means less oxygen reaches to the bloodstream. This deprives body organs of the oxygen they need to function.
Ventilation of the lungs occurs through breathing, which requires clear airways, an intact respiratory system, and a thoracic cavity capable of expanding and contracting. Oxygen diffuses from the alveoli into the blood while carbon dioxide diffuses from the blood into the alveoli. Factors like cardiac output, hematocrit levels, and exercise affect oxygen transport. Respiratory regulation maintains appropriate oxygen and carbon dioxide levels through neural and chemical controls. Alterations in respiratory function include hypoxia, hypoventilation, and hyperventilation which have signs and symptoms like anxiety, fatigue, and cyanosis.
This document summarizes pulmonary ventilation and oxygenation. It discusses the mechanics of breathing including inspiration and expiration. It also covers gas exchange in the lungs and blood, oxygen and carbon dioxide transport, and factors that can affect respiratory function such as medications, lifestyle, stress, and disease. Diagnostic tests for evaluating lung function are described. The nursing management of respiratory issues including promotion of oxygenation through various techniques is outlined.
Shock is a state of low tissue perfusion that can be fatal if not treated promptly. There are several types of shock based on the underlying pathophysiology, including hypovolaemic shock (from blood or fluid loss), cardiogenic shock (from heart failure), distributive shock (from sepsis or anaphylaxis), and obstructive shock (from embolism or pulmonary hypertension). Early resuscitation is crucial and involves restoring circulating volume through intravenous fluids while also identifying and treating the underlying cause of shock. Outcomes depend on limiting the duration of tissue hypoperfusion to prevent multiple organ failure.

4. • Oxygen
it is a colourless, odourless reactive gas, the chemical element of atomic number 8
and the life-supporting component of the air.
• Oxygenation
The delivery of oxygen to the body’s tissues and cells is called oxygenation.
4
6. Terms
related to
Oxygenatio
n
FiO2: Fraction of inspired oxygen
(%).
PaO2: The partial pressure of
oxygen in arterial blood. It is
used to assess the adequacy of
oxygenation.
normal range of 80–100 mmHg
SaO2: Arterial oxygen saturation
measured from blood specimen.
normal range of 95–100 mmHg
SpO2: Arterial oxygen saturation
measured via pulse oximetry.
normal SpO2 should be
between 96% to 99%
6
7. • Respiration
Respiration is a process of gas exchange, it's necessary to supply cells
with O2 for metabolism and to remove CO2.
• Mechanisms of respiration
The mechanisms of respiration require an integration of factors
involving
(1) nervous system,
(2) chemoreceptors in cardiovascular system, as well as
(3) respiratory system.
The respiratory system provides the essential first process in this
integrated system, that is movement and transfer of gases between the
atmosphere and the blood. Impaired function of the system can
significantly affect our ability to breathe, transport gases, and participate
in everyday activities. 7
10. Mechanisms of Cardiovascular system
• The heart is a pump, usually beating about 60 to 100 times per minute.
With each heartbeat, the heart sends blood throughout our bodies,
carrying oxygen to every cell. After delivering the oxygen, the blood
returns to the heart and carrying deoxygenated blood from body cells .
This cycle repeats over and over again
10
13. Factors affecting Oxygenation
• 1. Age: Oxygenation status can be influenced by age due lower
oxygen carrying capacity in lungs.
• 2. Environmental factor: Heat, cold and air pollution affect
oxygenation.
• 3. Lifestyle Factors: lifestyle factors can affect a client’s oxygenation
status: Physical exercise or activity increases the rate and depth of
respirations
• Occupations predispose individual to lung disease.
13
14. Factors affecting Oxygenation
• 4. Disease Processes: Oxygenation alterations can often be traced to disease
states related to alterations in ventilation, alveolar gas exchange, oxygen
uptake, or circulation. Many disease states may affect oxygenation,
including COPD, atelectasis, atherosclerosis, heart failure, and anemia.
• 5. Medications: a variety of medications can decreases rate and depth of
respirations. The most common medications are; sedative-hypnotics and
antianxiety drugs e.g., diazepam; and narcotics such as morphine.
• 6. Stress: the sympathetic nervous system is stimulated and epinephrine is
released during stress and causes the bronchioles to dilate..

• Only able to breathe comfortable in upright position (such as sitting in chair), unable
to breath laying down.
• Dyspnea
• Difficulty in breathing
• Paroxysmal nocturnal dyspnea - attacks of severe shortness of breath that wakes a
person from sleep, such that they have to sit up to catch their breath - common in
patient's with congestive heart failure.

• Hyperventilation
• "Over" ventilation - ventilation in
excess of the body's need for
CO2 elimination. Results in a
decreased PaCO2, and a
respiratory alkalosis.

26. Obstructed Airway
• A completely or partially obstructed airway can occur anywhere along the
upper or lower respiratory passage-ways .
• An upper airway obstruction
• That is ,in the nose ,pharynx ,larynx can arise foreign objects such as food ,
tongue falls back into the orophynx when a person is unconscious and when
secretions collect the passageways.
• Lower airway obstruction
• Is not always easy to observe .stridor ,a harsh ,high pitched sound ,may be
heard during inspiration .The client may have altered arterial blood gas levels,
restlessness dyspnea and adventitious breath sound (abnormal breath sound )

30. Cardiac output
• Cardiac output is the amount of blood pumped by the
heart per minute. It is the product of the heart rate,
which is the number of beats per minute, and the stroke
volume, which is the amount pumped per beat. CO =
HR X SV. The cardiac output is usually expressed in
liters /minute.
30
31. Decreased Cardiac output
• Decreased cardiac output is an often-serious medical
condition that occurs when the heart does not pump enough
blood to meet the needs of the body. It can be caused by
multiple factors, some of which include heart disease,
congenital heart defects, and low blood pressure.
31
32. Tissue Perfusion
• Blood is a connective tissue comprised of a liquid extracellular matrix
termed as blood plasma which dissolves and suspends multiple cells
and cell fragments. It carries oxygen from the lungs and nutrients from
the gastrointestinal tract. The oxygen and nutrients subsequently
diffuse from the blood into the interstitial fluid and then into the body
cells
32
33. Ineffective Tissue Perfusion
• Exchange of gases between the blood and the cells is
disrupted, meaning the cells (and ultimately the tissues and
organs) stop getting adequate oxygen supply. The body can’t
function without oxygen, so obviously this is a problem.
When tissues don’t receive enough oxygen through the
capillaries, this is called ineffective tissue perfusion.
• Many conditions can disrupt the exchange of oxygen and
carbon dioxide, but diabetes, obesity, anemia, high blood
pressure, and coronary artery disease are some of the more
common risk factors that can cause ineffective tissue
perfusion.

34. Blood Alteration
• Altering any one of the determinants of resistance (vessel length, vessel radius, or
blood viscosity) produces a change in flow.
• Vessel radius
• Vessel radius is the primary determinant of vascular resistance. that make up the
walls of the small arteries and arterioles contract and relax as a way of controlling
flow.
. Vessel length
• Blood flow through a vessel is inversely related to vessel length, again reflecting
blood's tendency to interact with the vascular endothelium.
• Blood viscosity
• Blood is a complex fluid, whose viscosity varies with flow. A fluid's viscosity is
measured relative to water. Adding electrolytes and organic molecules (including
proteins) to water raises viscosity from 1.0 cp to ~1.4 cp.

42. Nursing Measures to ensure a Patient Airway
Assessment of airway
• Colour
The colour of the patient’s skin and mucus membranes is a useful indicator of
haemoglobin saturation
• Pursed lips
A sign of respiratory compromise. The patient appears to pucker or purse his/her
lips, as if he/she is going to whistle
• Flared nostrils
Flaring of nostrils is another sign of respiratory distress
• Ability to speak
Increased effort to speak and/or inability to speak, as well as only being able to
speak in monosyllables
42
43. Conti…..
• Use of accessory
A patient who is in respiratory distress uses additional muscles to muscles
breathe. These include sterno-mastoid, scalene and abdominal muscles
• Rate, rhythm and depth
Nurses should assess whether the patients’ respiratory rate is above of
breathing or below normal level.
• Shape and expansion
it is important to consider of chest both the shape and expansion of the
chest.
43
44. Nursing Measures to ensure a
Patient Airway
• If cough is ineffective use suctioning as needed to remove sputum
and mucus plugs.
• Encourage adequate intake of fluids to prevent dehyderation.
• Administer medication as per order.
• Consult respiratory therapist for chest physiotherapy .
• Instruct patient how to use prescribed inhalator .
• Provide steam inhalation to clear the secretions.
• Oxygen administration .
44
45. Emergencies related to Respiratory System
• According European Respiratory Society
• . Hypoxic and hypercapnic respiratory failure
• Exacerbation of obstructive lung diseases: therapy
• Ventilation in obstructive lung disease
• . Acute respiratory distress syndrome
• Inhalation injury
• Extrapulmonary causes of respiratory failure including acute neuromuscular
disorders
• Management of massive haemoptysis
• Pneumothorax and bronchopleural fistula
• Pulmonary embolism
45
46. Devices used to Potent Airway
Low flow delivery method oxygen mask
• Simple face mask (It can deliver around 40 percent to 60 percent oxygen at 6 to 10 L/min)
• Non re-breather face mask (A non-rebreather mask can deliver between 60 percent to 80 percent oxygen at a
flow rate of about 10 to 15 liters/minute (L/min)
• Nasal prongs (low flow) (24% to 40% O2 1 to 6 litres per minute (L/min)
• Tracheostomy mask
• Tracheostomy HME connector
• Isolette - neonates (usually for use in the Neonatal Intensive Care Unit only)
46
55. Emergencies related to Cardiovascular System
• Acute Coronary Syndrome.
• Heart Failure.
• Hypertension and Hypertensive Crisis.
• Pericarditis, Pericardial Effusion, and Cardiac Tamponade.
• Myocarditis and Cardiomyopathy.
• Aortic Aneurysms and Dissections.
• Congenital Heart Disease.

56. Explain ways that caregivers can decreases the exposure of clients
to infection .
Infection control includes various measures that prevent and contain the
spread of infectious disease. These measures include:
Hand Washing
Infection control standard, contact, droplet and airborne precautions
Procedures for decontamination of persons and disinfection of
equipment and the environment
Quarantine of contacts (if necessary)
Prophylaxis of exposed individuals
Control of the vectors of infection
56
57. 5 Standard Precautions for Infection
Control
• Standard Precautions
• Hand hygiene.
• Use of personal protective equipment (e.g., gloves, masks,
eyewear).
• Respiratory hygiene / cough etiquette.
• Sharps safety (engineering and work practice controls).
• Safe injection practices (i.e., aseptic technique for parenteral
medications).
• Sterile instruments and devices.
57
59. Surgical vs Medical Asepsis
Medical asepsis is the reduction of the number of disease-causing
agents and their spread.
Surgical asepsis is the complete elimination of the disease-
causing agents and their spores from the surface of an object.
Techniques
The techniques used in the process are called clean techniques. In surgical asepsis, sterile techniques are used.
Occasions
This procedure is carried out in the administration of enemas,
medications, tube feedings, etc.
Sterile techniques are followed in changing dressings of a wound,
catheterization, and surgeries.
