Anaesthetic machine safety features

Anaesthetic machine safety features

This module covers the safety features built into the modern anaesthetic machine. With more theatres moving to electronic self-checking machines this is a useful reminder of where we have come from and how safety is built into all aspects of the anaesthetic machine. It is also useful for anyone new to anaesthetics.

Awareness under Anaesthesia

Awareness under Anaesthesia

Awareness during anaesthesia can be very distressing for a patient, particularly if accompanied by recall of the painful nature of surgery. This article explores the types, incidence, consequences, causes, management and avoidance of intraoperative awareness.

Arterial Blood Pressure Measurement – The physics

Arterial Blood Pressure Measurement – The physics and principles.

Intra-arterial blood pressure measurement is often considered to be the gold standard of blood pressure measurement. This accuracy however, depends on a number of physical principles of the systems used, which are explored in this advanced module.
The is also a separate easier module available covering setting up and using arterial lines.

Apnoea & Pre-oxygenation

Apnoea & Pre-oxygenation

Pre-oxygenation is used in anaesthesia to prolong the time to desaturation during a period of apnoea, such as frequently happens upon induction. This can also be thought of a denitogenation. This article covers the science behind it and discusses some patient groups that need special attention.

Physiological effects of transfer for critically ill patients

Physiological effects of transfer for critically ill patients

Critically ill patients can be exposed to significant physiological changes during transfer that can lead to significant instability with hypoxia, hypotension, arrhythmias and changes in intracranial pressure (ICP). This tutorial will explore the physiological effects that land and air transfer have on critically ill patients and describe how these adverse physiological sequelae can be avoided or reduced.
