Chronic bronchitis & emphysema
Chronic bronchitis and emphysema are both forms of COPD characterized by airflow obstruction. Chronic bronchitis involves long-term inflammation of the bronchial tubes causing excess mucus. Emphysema damages air sacs in the lungs reducing their elasticity. The main symptoms are shortness of breath and cough. Smoking is the primary cause and treatments include bronchodilators, steroids, oxygen therapy, and lifestyle changes like quitting smoking and exercise.
Bronchiectasis.
This document discusses bronchiectasis, including its definition, etiology, clinical features, diagnosis, management, and complications. Some key points:
- Bronchiectasis is irreversible dilation of the airways caused by infection or other insults that damages the airways and impairs mucus clearance.
- It has various etiologies including infection, immunodeficiency, genetic disorders, and aspiration. Recurrent infections lead to a vicious cycle of inflammation and further airway damage.
- Symptoms include chronic productive cough and sputum. Investigations include chest CT, which shows characteristic findings like airway dilation.
- Management focuses on airway clearance, antibiotics for infections, and
Respiratory failure
This document discusses respiratory failure, which occurs when the respiratory system fails in gas exchange. It defines two main types - hypoxemic respiratory failure, defined as low blood oxygen, and hypercapnic respiratory failure, defined as high blood carbon dioxide. The document then covers the anatomy and physiology of respiration, diagnostic evaluation of respiratory failure, treatment including mechanical ventilation, and specific causes of respiratory failure like infection, airway obstruction, and cardiac issues.
Respiratory failure
This document discusses the four types of respiratory failure:
1) Type 1 (hypoxemic) is characterized by low oxygen levels in the blood but normal or low carbon dioxide levels, usually due to issues with ventilation/perfusion matching.
2) Type 2 (hypercapnic/ventilatory) involves low oxygen and high carbon dioxide levels due to inadequate alveolar ventilation.
3) Type 3 (peri-operative) commonly occurs after surgery due to effects of anesthesia and abdominal issues.
4) Type 4 (shock) involves intubation during resuscitation for conditions like cardiogenic, hypovolemic, or septic shock. The document then provides details on the causes, characteristics
Incentive spirometry ppt
Incentive spirometry is a device used to encourage deep breathing through visual or other feedback. It aims to prevent or treat lung atelectasis by improving inspiratory volumes and muscle performance. It is indicated for patients at risk of lung collapse after surgery or with conditions limiting breathing. Effective use requires slow, deep breaths holding for 5 seconds, 10-15 breaths every 1-4 hours while awake. Potential risks include fatigue, hypoxemia or respiratory alkalosis if not used properly. There is low evidence for its effectiveness in preventing complications after upper abdominal surgery.
Weaning from mechanical ventilation
The document discusses weaning patients from mechanical ventilation. It begins by defining weaning as the process of withdrawing ventilator support and transferring breathing work to the patient. It states that patients must recover from their acute illness and be able to breathe spontaneously before weaning. Weaning is gradually started by evaluating clinical status and giving spontaneous breathing trials to assess readiness for extubation. Different ventilator modes used for weaning, like pressure support ventilation, are described. Weaning criteria involving clinical, ventilatory, oxygenation, and pulmonary measurements are provided to determine weaning success. The weaning procedure, including spontaneous breathing trials and parameters like the rapid shallow breathing index to predict weaning outcome, are outlined. Causes of we
Management of Respiratory Failure
This document discusses respiratory failure, defined as inadequate oxygenation, ventilation, or both to meet metabolic demands. It can be classified as type 1 (hypoxemic) or type 2 (hypercapnic) respiratory failure. Risk factors include age, smoking, lung disease, and neurological or muscular disorders. Pathophysiology involves ventilation-perfusion mismatching, right-to-left shunting, or hypoventilation. Causes include pneumonia, pulmonary embolism, neuromuscular disorders, and acute respiratory distress syndrome. The control of breathing and gas exchange physiology are also summarized.

Peep & cpap
1. Functional residual capacity (FRC) is the amount of air in the lungs after a normal expiration and is dependent on factors like sex, age, height, and weight. FRC increases with age and decreases with weight.
2. Positive end-expiratory pressure (PEEP) maintains a positive pressure during expiration to keep alveoli inflated, which increases functional residual capacity and improves oxygenation. PEEP is indicated for refractory hypoxemia, intrapulmonary shunts, and decreased FRC and lung compliance.
3. Complications of PEEP include decreased venous return, decreased cardiac output, barotrauma, increased intracranial pressure, and altered renal function
Humidification Therapy
Humidity therapy adds moisture to air delivered to patients and is used to overcome humidity deficits when the upper airway is bypassed or for humidifying dry medical gases. It helps maintain normal humidity levels in the airways and can assist in managing conditions like thick secretions or hypothermia. Various humidifiers actively add heat or water to air or passively recycle exhaled heat and moisture, with different types suited to invasive or non-invasive ventilation.
peak expiratory flow rate presentation
This document discusses peak expiratory flow rate (PEFR), including its purpose, measurement steps, and significance. PEFR is measured using a peak flow monitor to assess, diagnose, manage, and determine prognosis of lung diseases like asthma. It involves preparing the device, standing up straight, taking a deep breath, and blowing hard into the mouthpiece to measure airflow in L/min. Normal PEFR values vary based on age, sex, and height but are generally above 500 L/min for adult males and 400 L/min for adult females. PEFR tests allow patterns in airflow to be monitored over time to help adjust medications or identify environmental triggers.
5.Bronchiectasis
Bronchiectasis is a chronic lung condition defined by abnormal dilation of the bronchi caused by inflammation and damage to the bronchial walls. It has several causes including post-infection, airway obstruction, immune deficiencies, and genetic disorders. Patients experience excessive sputum production, chronic cough, recurrent pneumonia, and sometimes hemoptysis. Diagnosis involves imaging like CT scans showing characteristic findings and ruling out other conditions. Treatment focuses on airway clearance and long-term antibiotics tailored to sputum cultures. Surgery may be considered for severe, localized cases or massive hemoptysis.
Humidification therapy

It describes three main mechanisms of aerosol deposition - inertial impaction, sedimentation, and diffusion - and how particle size affects each. It also discusses different aerosol delivery devices (pMDIs, DPIs, nebulizers), how they work, advantages and disadvantages. Patient-related factors like age, breathing pattern and airway geometry are also reviewed as important considerations for effective aerosol therapy.
Pulmonary embolism ppt
The document discusses pulmonary embolism, which is the blockage of pulmonary arteries by blood clots or other materials. It defines pulmonary embolism and discusses its incidence, risk factors including deep vein thrombosis, clinical features such as chest pain and dyspnea, pathophysiology involving right heart strain, diagnostic studies, and treatment including anticoagulation with heparin and warfarin as well as surgical interventions in severe cases.
Pneumothorax
This document discusses pneumothorax, beginning with a definition and overview of types including spontaneous, traumatic, and tension pneumothorax. Risk factors are identified such as male sex, smoking, age, genetics, and lung disease. Diagnosis involves physical exam findings and imaging tests like chest x-ray and CT scan. Treatment goals are promoting lung expansion and eliminating causes, using methods such as aspiration, tube drainage, or surgery. Complications are also reviewed.
Emphysema
Emphysema is a condition that damages the air sacs in the lungs called alveoli, causing them to lose their elasticity and become enlarged. This makes breathing difficult. The main causes are smoking cigarettes and exposure to air pollution or dust. Symptoms include shortness of breath, coughing, and fatigue. Diagnosis involves medical history, physical exam, chest X-rays, and lung function tests. Treatment focuses on quitting smoking, using inhalers, oxygen therapy, exercise, and lifestyle changes. Managing the condition can help prevent further lung damage and associated complications.
Emphysema and therapeutics
Emphysema is a chronic lung disease characterized by the destruction of lung tissue and the abnormal enlargement of air spaces in the lungs. It is primarily caused by smoking and long-term exposure to air pollutants. A CT scan can detect emphysema by showing decreases in lung density and pulmonary vessels. The main symptoms are shortness of breath and reduced exercise capacity. Treatment focuses on pulmonary rehabilitation, which aims to improve quality of life through exercise and education. Preventing emphysema involves avoiding smoking and other lung irritants.
Bronchospasm ppt
Dr. Imran's document discusses the management of intraoperative bronchospasm. It defines bronchospasm as constriction of the smooth muscles of the bronchi and bronchioles. It then covers the anatomy, innervation, causes, signs and symptoms, diagnosis, pathophysiology, anesthetic agents that can cause it, and treatment of bronchospasm. The treatment involves deepening anesthesia, administering bronchodilators like salbutamol, and other drugs like ipratropium bromide, magnesium sulfate, and hydrocortisone to reverse bronchoconstriction and prevent hypoxia.
Hypoxia & hypoxemia
The document discusses hypoxia, or low oxygen levels in body tissues. It defines four types of hypoxia: hypoxemic caused by low blood oxygen levels, anemic caused by low hemoglobin, stagnant caused by reduced blood flow, and histotoxic caused by tissues' inability to use oxygen. It then provides more details on the causes and mechanisms of each type, focusing on hypoxemic hypoxia which can result from low atmospheric oxygen or lung issues preventing oxygen transfer from air to blood. Ventilation-perfusion mismatch is highlighted as a common cause of hypoxemia, or low blood oxygen levels, which can in turn cause hypoxia in tissues. Early detection using a pulse oximeter and treatments like supplemental oxygen
Acute respiratory failure ppt
Acute respiratory failure occurs when the respiratory system fails to maintain adequate gas exchange. There are two main types: hypoxemic respiratory failure, characterized by low oxygen levels, and acute ventilatory failure, characterized by high carbon dioxide levels. Hypoxemic failure is most common and can result from conditions that impair gas exchange like pneumonia or pulmonary edema. Ventilatory failure involves impaired breathing and can be caused by conditions that increase breathing workload like COPD. Diagnosis involves blood gas analysis and imaging. Treatment focuses on supporting oxygenation and ventilation through oxygen supplementation, ventilation support, and treating underlying causes.
BRONCHIAL ASTHMA
This document provides information on bronchial asthma including its definition, classification, pathophysiology, and treatment approaches. It discusses the different types of asthma such as atopic, non-atopic, and drug-induced asthma. It describes the cells and mediators involved in asthma inflammation. It covers the mechanisms and classes of drugs used to treat asthma, including bronchodilators, leukotriene antagonists, mast cell stabilizers, corticosteroids, and anti-IgE antibody. It provides details on the mechanisms of action and side effects of various bronchodilators and corticosteroids. It also discusses inhalational drug delivery systems and the treatment of acute asthma attacks.
Bpap (bi level positive airway pressure)
1. Bilevel positive airway pressure (BPAP) delivers two levels of positive airway pressure - a higher pressure during inspiration and a lower pressure during expiration - to reduce work of breathing and improve oxygenation.
2. BPAP is effective for acute exacerbations of COPD and cardiogenic pulmonary edema by reducing mortality, need for intubation, and treatment failure compared to standard care.
3. For pneumonia, outcomes are worse with post-obstructive pneumonia, pleural effusions, hypoxic hypercapnic respiratory failure with effusions, and over 24 hours on BPAP therapy.
Chronic bronchitis
Chronic bronchitis is defined as a persistent cough with mucus production for at least three months in a year for two consecutive years. It is primarily caused by long-term irritation and inflammation of the airways due to cigarette smoke or other inhaled chemicals. Chronic bronchitis can progress to more severe lung diseases like COPD or lung cancer and, if left untreated, may result in heart failure or respiratory infections. The pathology involves damage to the airways, thickening of the mucus membranes, and increased mucus production.
Obstructive Lung Diseases
1. The document discusses several obstructive lung diseases including emphysema, chronic bronchitis, asthma, and bronchiectasis.
2. Emphysema is characterized by destruction of alveolar walls without significant fibrosis leading to enlarged air spaces. Chronic bronchitis involves thickening of bronchial walls and excess mucus production.
3. Asthma is a chronic inflammatory disease involving recurrent airway obstruction, inflammation, and hyperresponsiveness triggered by various stimuli. Bronchiectasis permanently dilates the bronchi and bronchioles due to destruction of muscles and tissues often caused by infection or obstruction.
Ventilation perfusion relationships
Gas exchange between the alveoli and the pulmonary capillary blood occurs by diffusion, as will be discussed in the next chapter. Diffusion of oxygen and carbon dioxide occurs passively, according to their concentration differences across the alveolar-capillary barrier. These concentration differences must be maintained by ventilation of the alveoli and perfusion of the pulmonary capillaries.
Alveolar ventilation brings oxygen into the lung and removes carbon dioxide from it. Similarly, the mixed venous blood brings carbon dioxide into the lung and takes up alveolar oxygen. The alveolar Image not available. and Image not available. are thus determined by the relationship between alveolar ventilation and pulmonary capillary perfusion. Alterations in the ratio of ventilation to perfusion, called the Image not available., will result in changes in the alveolar Image not available. and Image not available., as well as in gas delivery to or removal from the lung.
Alveolar ventilation is normally about 4 to 6 L/min and pulmonary blood flow (which is equal to cardiac output) has a similar range, and so the Image not available. for the whole lung is in the range of 0.8 to 1.2. Image not available. However, ventilation and perfusion must be matched on the alveolar-capillary level, and the Image not available. for the whole lung is really of interest only as an approximation of the situation in all the alveolar-capillary units of the lung. For instance, suppose that all 5 L/min of the cardiac output went to the left lung and all 5 L/min of alveolar ventilation went to the right lung. The whole lung Image not available. would be 1.0, but there would be no gas exchange because there could be no gas diffusion between the ventilated alveoli and the perfused pulmonary capillaries.
Oxygen is delivered to the alveolus by alveolar ventilation, is removed from the alveolus as it diffuses into the pulmonary capillary blood, and is carried away by blood flow. Similarly, carbon dioxide is delivered to the alveolus in the mixed venous blood and diffuses into the alveolus in the pulmonary capillary. The carbon dioxide is removed from the alveolus by alveolar ventilation. As will be discussed in Chapter 6, at resting cardiac outputs the diffusion of both oxygen and carbon dioxide is normally limited by pulmonary perfusion. Thus, the alveolar partial pressures of both oxygen and carbon dioxide are determined by the Image not available. If the Image not available. in an alveolar-capillary unit increases, the delivery of oxygen relative to its removal will increase, as will the removal ...
Emphysema
1. Emphysema is a chronic obstructive pulmonary disease characterized by abnormal enlargement of the airspaces in the lungs accompanied by destruction of their walls.
2. The main symptoms of emphysema include dyspnea, recurrent respiratory infections, and right heart failure. Chest imaging shows increased lung volumes and flattened diaphragms.
3. There are several classifications of emphysema based on the areas of the lung affected, including centriacinar, panacinar, paraseptal, and mixed emphysema. Cigarette smoking is a major risk factor and can cause an imbalance of proteases and antiproteases in the lungs.
Chronic Obstuctive Pulmonary Disease (COPD) - arp
Chronic Obstructive Pulmonary Disease is a preventable and treatable disease characterized by persistent airflow limitation that is usually progressive and associated with an enhanced chronic inflammatory resposnse in the airways and lung to noxious particles or gases.

The carbon dioxide is removed from the alveolus by alveolar ventilation. As will be discussed in Chapter 6, at resting cardiac outputs the diffusion of both oxygen and carbon dioxide is normally limited by pulmonary perfusion. Thus, the alveolar partial pressures of both oxygen and carbon dioxide are determined by the Image not available. If the Image not available. in an alveolar-capillary unit increases, the delivery of oxygen relative to its removal will increase, as will the removal ...

07 capnography trends in procedural sedation
1) Procedural sedation is used for many medical procedures and aims to provide analgesia, amnesia, and reduce anxiety while maintaining airway reflexes and spontaneous breathing.
2) While pulse oximetry became standard in the 1980s, capnography has emerged as the new gold standard for monitoring procedural sedation as it can detect respiratory issues that oximetry may miss.
3) Overlake Hospital implemented capnography monitoring for all procedural sedations after reviewing evidence and determining it was more effective for patient safety than relying on respiratory therapists to continuously monitor each procedure.
The evolution of pediatric mechanical ventilators
1. Mechanical ventilators have evolved from simple analog machines to sophisticated microprocessor-controlled devices with advanced modes of ventilation.
2. Early ventilators were open-loop controlled while modern ventilators use various closed-loop and dual-loop control schemes to better match ventilation to patient needs.
3. The newest generations of ventilators use proportional assist, automatic tube compensation, adaptive support ventilation, and other advanced modes that aim to provide more patient-synchronized support and facilitate weaning. However, further research is still needed to fully understand the outcomes of these newer ventilation strategies.
20 patient monitoring

It also reviews normal airway management techniques like bag-mask ventilation and various airway devices, as well as complications from intubation. The goal is to protect, adequately ventilate, and oxygenate the pediatric airway.
17 capnography part4 non-intubated
The document discusses the use of capnography for non-intubated patients experiencing trouble breathing. It describes how capnography can help identify and monitor conditions like bronchospasm from asthma or COPD by examining patterns in exhaled carbon dioxide levels. Specific capnographic signatures are presented for different respiratory conditions including asthma attacks, COPD exacerbations, congestive heart failure, and hypoventilation states. Case studies demonstrate how capnography can track changes in a patient's condition before and after treatment.
16 capnography part3 intubated
Capnography can be used to summarize 3 key applications for intubated patients:
1) It can confirm correct endotracheal tube placement and detect displacement. Characteristic waveforms indicate proper vs displaced placement.
2) During CPR, it can assess the effectiveness of chest compressions by correlating end-tidal CO2 levels with cardiac output and blood flow.
3) It provides an early indicator of return of spontaneous circulation through a rapid rise in CO2 levels, earlier than other signs like pulse or blood pressure. It also aids the decision to cease resuscitation efforts based on CO2 levels.
15 capnography part2 introduction
Capnography measures exhaled carbon dioxide (CO2) to provide real-time monitoring of ventilation, unlike pulse oximetry which monitors oxygen saturation in the blood and is slower to detect changes. A normal capnographic waveform has four phases: 1) dead space, 2) ascending, 3) alveolar plateau, and 4) descending. The end-tidal CO2 value reflects the highest CO2 concentration in exhaled air and typically ranges from 35-45mmHg. Capnography can immediately detect conditions that impact ventilation such as hypoventilation, hyperventilation, and bronchospasm based on changes to the waveform shape, frequency, and CO2 values.
14 capnography part1 overview
This document provides an overview of capnography, which is a technology that objectively measures ventilation by detecting exhaled carbon dioxide. It can be used for both intubated and non-intubated patients to continuously monitor ventilation and the patient's ABCs. The document reviews the history of capnography, from its initial use in operating rooms to new portable technologies suitable for emergency medical services. It also outlines the clinical applications of capnography such as verifying endotracheal tube placement and monitoring treatment effectiveness.
13 icu monitoring standards and capnography
Dr. Ajmal Eusuf discusses the importance and benefits of capnography monitoring in the ICU. Capnography can be used to confirm proper endotracheal tube placement, monitor ventilation, and detect various respiratory issues. While capnography is standard practice in operating rooms and recommended by guidelines, only about half of UK ICUs currently use it as a mandatory monitoring tool. Adopting capnography as routine bedside monitoring in the ICU would help compliance with protocols and better patient care, especially for critically ill patients who are sicker than those in operating rooms.
12 mainstream sidestream capnpgraphy
The document discusses two options for capnography monitoring from ZOLL - the CAPNOSTAT 3 mainstream CO2 sensor and the LoFlo sidestream CO2 module. It provides details on the benefits of each, such as the CAPNOSTAT sensor's accuracy and resistance to contaminants, and the LoFlo module's interchangeability and low 50ml/min sampling rate. The document emphasizes that both provide reliable, accurate CO2 monitoring and waveforms for assessing patient ventilation.
