Bronchodilators are medications that work by stimulating beta-2 receptor sites to relax airway smooth muscle, dilate the airways, and lower resistance to airflow, helping to decrease respiratory effort. Common bronchodilators include albuterol, metaproterenol, isoetharine, bitolterol mesylate, and salmeterol xinafoate, which are supplied in metered-dose inhalers or nebulizers to treat shortness of breath, wheezing, and other symptoms in patients who are not at their maximum medication dose from their personal inhaler.

It describes various drug classes used to treat asthma, including β2 agonists, corticosteroids, leukotriene modifiers, and others. It outlines administration routes, devices, and techniques for delivering asthma medications via inhalers, nebulizers, and orally. Side effects of different drug classes are also summarized. Methods for studying the effects of bronchoconstrictors and bronchodilators on isolated guinea pig trachea are then outlined.
Drugs used in respiratory disorders
This document discusses drugs used to treat respiratory disorders such as cough and bronchial asthma. It classifies drugs used for cough into pharyngeal demulcents, expectorants, antitussives, and adjuvant antitussives. Drugs for bronchial asthma include bronchodilators, leukotriene antagonists, mast cell stabilizers, and corticosteroids. Salbutamol is discussed as a selective beta-2 agonist bronchodilator used to treat asthma and COPD. Its mechanism of action and side effects like hypokalaemia and tremors are explained. Antihistamines are classified based on generation, with first-generation being more sedating and second-generation having higher selectivity
Asthma
This document outlines the management of asthma according to a stepwise treatment approach. It describes investigating asthma through lung function tests, bloodwork, and allergy tests. Treatment begins with occasional use of short-acting bronchodilators for mild symptoms. For daily symptoms, low-dose inhaled corticosteroids are used. More severe symptoms use combination inhaled corticosteroids and long-acting bronchodilators. High-dose inhaled corticosteroids or combination inhalers are used for uncontrolled severe symptoms. Oral corticosteroids are used for deteriorating severe symptoms. Acute severe asthma is treated with oxygen, high-dose inhaled bronchodilators, corticosteroids, and magnesium

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
The document discusses various methods of patient monitoring during anesthesia, including their purposes, advantages, and limitations. It covers monitoring vital signs, standards for basic anesthesia monitoring according to the ASA, techniques like non-invasive blood pressure monitoring, ECG, pulse oximetry, capnography, and invasive arterial line monitoring. Key aspects emphasized are integrating multiple monitoring methods to evaluate oxygenation, ventilation, and circulation.
19 introduction of volumetric capnography
The document discusses the introduction and clinical applications of volumetric capnography (VCO2) at one hospital. It provides an agenda for the topics covered, which include VCO2 management, clinical applications, and data from the University of Tennessee Medical Center's experience using VCO2. Key applications discussed are ventilation management, monitoring changes in perfusion, optimization of positive end-expiratory pressure, and assisting with ventilator weaning trials. The University of Tennessee Medical Center saw decreases in length of mechanical ventilation, ventilator days, and re-intubation rates after implementing VCO2 monitoring.
18 basics of pediatric airway anatomy, physiology and management
The document provides an overview of pediatric airway anatomy, physiology, and management. It discusses the differences between pediatric and adult airways, including a more rostral larynx, relatively larger tongue, angled vocal cords, differently shaped epiglottis, and funneled larynx in children. 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.
