There is a lot of focus on capnography and waveform capnography. Both revolve around End-tidal carbon dioxide (EtCO₂), but what exactly is it? To understand EtCO₂, it is useful to understand the respiratory process.
What is Capnography? Capnography is the measurement of the partial pressure of CO₂ during breathing. It is a non-invasive method that provides information on ventilation, perfusion and metabolism, all of which are extremely important for airway management[1]. If you would like to learn more about capnography, you can read our pages ‘What is Capnography?’ and ‘What is Waveform Capnography?’. […]
Capnography masks are used to detect the levels of CO₂ in the blood by measuring End-tidal Carbon Dioxide (EtCO₂). EtCO₂ is the level of CO₂ left at the end of an exhaled breath, reflecting the adequacy with which CO₂ is carried in the blood back to the lungs to be exhaled. It is important to measure EtCO₂ […]
Currently, in the UK and Ireland, general anaesthesia (GA) is most induced by administering a bolus of intravenous anaesthetic drugs and is then maintained through the use of inhaled anaesthetic agents.
What are the advantages of total intravenous anaesthesia (TIVA)? Total intravenous anaesthesia (TIVA) is the induction and maintenance of an anaesthetic state using only intravenous drugs, as opposed to a combination of intravenous drugs and gas inhalants. The advantages of total intravenous anaesthesia Propofol – based Total Intravenous Anaesthesia has a number of advantages including […]
What is PONV Postoperative nausea and vomiting (PONV) is a post-surgical, adverse reaction patients experience after general anaesthesia. It has a negative effect on patients’ recovery, which extends hospital admission time.1 What causes PONV? Several perioperative stimuli can trigger PONV, including opioids, volatile anaesthetics, anxiety, adverse drug reactions and motion. Patient factors also influence the […]
