Impact of anesthesia on respiratory systemisrar khanThis document discusses the effects of anesthesia on respiratory physiology. It notes that general anesthesia can impair ventilation through airway obstruction and loss of airway patency. It also reduces ventilation by decreasing respiratory rate or tidal volume. This causes hypoxia and hypercapnia. Anesthesia also decreases functional residual capacity, causing more hypoxia. The document outlines these effects for different anesthetic agents and recommends preparations like positioning and pre-oxygenation to mitigate risks to ventilation and gas exchange under anesthesia.
Compliance and resistancehamna rafaqatThe document describes two individuals' experiences with smoking and related health issues. Michael started smoking at age 9 and was diagnosed with COPD at age 44. He struggled to quit smoking until having a health scare at age 52 that prompted him to stop. He had lung surgery and is working to improve his health. The document also describes an unnamed woman who started smoking as a teenager and was later diagnosed with oral cancer at age 25 and throat cancer at age 40. She underwent radiation therapy and surgery but continued smoking and passed away from her health issues at age 53.
Ventilator graphicsAhmed HegazyThis document provides an overview of neonatal ventilator graphics and waveforms. It discusses the key waveforms of pressure, volume, and flow and how they depict the respiratory cycle. Specific features of each waveform are described, including how they can reveal conditions like leaks, auto-triggering, gas trapping, and changes in compliance. Pulmonary loops like the pressure-volume and flow-volume loops are introduced and how they can provide information about lung mechanics, resistance, compliance, and other conditions. Interpretation of loop features is covered for various pathological states and responses to treatments.
Mechanical Ventilation.pptxPunitTiwari40Mechanical ventilation uses positive pressure to deliver gas to the lungs. There are several modes that have evolved over time including negative pressure ventilation and newer microprocessor controlled positive pressure systems. The basic function is to deliver gas to the lungs while parameters like tidal volume, respiratory rate, pressures and timing are adjusted based on the patient's condition and response. Common modes include controlled mandatory ventilation which provides all breaths from the ventilator, assist control which provides mandatory breaths plus additional breaths if patient triggers, and synchronized intermittent mandatory ventilation which aims to prevent breath stacking by synchronizing mandatory breaths with patient effort.
Respiratory changes during anesthesia and ippvImran SheikhAnesthesia causes impairment of respiratory function through several mechanisms. It decreases functional residual capacity and lung compliance while increasing respiratory resistance. This leads to atelectasis in 15-20% of the lung and ventilation/perfusion mismatching. Maintaining muscle tone, applying positive end-expiratory pressure, recruitment maneuvers using sustained high inspiratory pressures, and limiting oxygen concentrations can help prevent atelectasis formation. Anesthesia also redistributes ventilation away from dependent lung regions and inhibits hypoxic pulmonary vasoconstriction.
New modes of mechanical ventilation TRCchandra talurThe document discusses newer modes of mechanical ventilation that were introduced to address clinical issues like poor patient-ventilator synchrony, prolonged weaning times, and ventilator-induced lung injury. It classifies the newer modes as dual modes that combine volume and pressure control, modes that adapt to lung characteristics, and knowledge-based weaning modes. It provides more details on proportional assist ventilation (PAV+), airway pressure release ventilation (APRV/BIPAP), and Smartcare—modes that aim to improve synchrony, maintain high functional residual capacity, and reduce workload for clinicians respectively.
Basics of neonatal ventilation 1Abid Ali RizviThe document discusses the basics of neonatal ventilation. It explains that ventilation is used to provide oxygenation, remove carbon dioxide, and assist breathing in neonates. Key parameters discussed include peak inspiratory pressure, positive end expiratory pressure, compliance, resistance, tidal volume, and minute volume. Different modes of ventilation are also summarized, including their advantages and limitations. The importance of synchronization between the ventilator and patient's breathing is emphasized to reduce work of breathing and other complications.
Module 2.5 Invasive & Non-Invasive VentilationHannah NelsonInvasive ventilation requires an artificial airway such as an endotracheal tube or tracheostomy tube connected to a mechanical ventilator. Non-invasive ventilation uses a nasal or face mask without an artificial airway. Both methods provide positive pressure to support breathing. Invasive ventilation is used when the airway needs protection or for severe respiratory failure, while non-invasive ventilation is preferred when possible due to lower risk of complications. Careful monitoring is needed for both methods and weaning should begin as soon as the patient can safely breathe independently.
INFOGRAPHICS in ANAESTHESI by Dr. Tushar Chokshi.pptxtusharchokshi1Dr. Tushar Chokshi has completed 20 months creating over 130 infographics in anesthesiology. He was inspired to create these after seeing how a 5-year-old child responded well to educational infographics. Each infographic takes 5-10 hours to create and involves extensive research. The goal is to provide easy to understand single page summaries of medications, procedures, and other anesthesia topics through a visually appealing format.
basicmodesofmechanicalventilation-160117181821 (1).pptxTufan BhutadaMechanical ventilation uses machines called ventilators to generate a controlled flow of gas into a patient's airways to support breathing. There are several basic modes of ventilation including controlled mandatory ventilation (CMV), assist-control ventilation, intermittent mandatory ventilation (IMV), and synchronized intermittent mandatory ventilation (SIMV). CMV controls both the tidal volume and respiratory rate while assist-control adds spontaneous breaths triggered by the patient. IMV and SIMV allow some spontaneous breathing but can cause breath stacking. Pressure support ventilation provides pressure assistance for spontaneous breaths with the patient determining the tidal volume.
Patient-ventilator dyssynchrony.pptxAmruta MankarThis document discusses patient-ventilator dyssynchrony, which occurs when a patient's respiratory demands are not appropriately met by the ventilator. This can increase the patient's work of breathing, lead to distress, and prolong the need for ventilation. Dyssynchrony can be caused by inappropriate ventilator settings, modes where the patient is fighting the ventilator, or issues like auto-triggering. Identifying the type and cause of dyssynchrony is important to optimize ventilator support and improve the patient experience.

Vent modesreisbir1) The document provides an overview and explanation of various ventilator modes including IMV, AC/VC, PC, SIMV, PRVC, and HFOV.
2) Key settings that can be adjusted on ventilators include rate, inspiratory time/flow, tidal volume, FiO2, and PEEP. Compliance can also impact how easily a breath is delivered.
3) To improve oxygenation, one can increase FiO2 and PEEP which recruits more alveoli. To lower CO2, one can increase rate/tidal volume or decrease rate on HFOV to allow more time for exhalation.
Lung Protective Ventilation Dr. S.K. Varma This document discusses protective lung ventilation strategies during and after cardiac surgery to reduce postoperative pulmonary complications (PPCs). It notes that as many as 20% of patients undergoing cardiac surgery develop acute respiratory distress syndrome (ARDS), which has a high mortality rate. Protective ventilation strategies using lower tidal volumes, positive end-expiratory pressure (PEEP), and recruitment maneuvers have been shown in randomized controlled trials to reduce inflammatory markers and incidence of PPCs compared to conventional ventilation with higher tidal volumes and no PEEP. The IMPROVE trial also found protective ventilation during abdominal surgery reduced postoperative pulmonary and extrapulmonary complications and length of ICU stay compared to non-protective ventilation.
