Anesthesia equipment malfunction: origins and clinical recognition
Canadian Medical Association Journal
|April 21, 1979
Summary
Equipment malfunction during anesthesia and resuscitation poses significant risks. Preventing patient harm requires adherence to standards, proper equipment evaluation, user training, diligent maintenance, and pre-anesthesia checks.
Area of Science:
- Anesthesiology
- Medical Device Safety
Background:
- Equipment malfunction is a critical issue in anesthesia and resuscitation.
- Common failures involve endotracheal tubes, oxygen concentration, anesthetic gas volumes, and ventilation system pressures.
Purpose of the Study:
- To review common equipment malfunctions during anesthesia and resuscitation.
- To outline strategies for preventing patient harm due to equipment failure.
Main Methods:
- Review of published reports on anesthesia and resuscitation equipment failures.
Main Results:
- Identified common clinical events linked to equipment malfunction.
- Highlighted key areas of equipment failure: endotracheal tubes, inspired oxygen, anesthetic vapor/gas volumes, and breathing system pressures.
Conclusions:
- Patient safety from equipment malfunction relies on multiple factors.
- Essential preventative measures include standards compliance, pre-purchase evaluation, user education, routine servicing, pre-anesthesia testing, and prompt, safe corrective actions.

01:25Errors occurring during blood pressure monitoring
Blood pressure monitoring is a crucial clinical procedure in diagnosing and managing various cardiovascular conditions. Despite its significance, the accuracy of blood pressure measurements can be compromised by multiple factors, potentially leading to either falsely high or low readings. These inaccuracies are critical as they can significantly impact patient care. So, it is vital to understand these challenges deeply and adopt strategic approaches to minimize errors.

01:12Local Anesthetics: Adverse Effects
While local anesthetics are generally safe and well-tolerated, they can occasionally cause adverse effects that vary in severity. Local anesthetics can induce toxicity at two distinct levels. They can either produce local effects through direct contact with the neural elements or be absorbed into the bloodstream from the injection site, leading to systemic effects.
Once absorbed into the systemic circulation, local anesthetics can affect the organs that depend on the functioning of sodium...

01:24General Anesthesia: Overview
Anesthesia is a medical procedure that uses drugs for CNS suppression to enable painless surgeries and procedures. The selection of anesthetics is influenced by their pharmacokinetic properties, side effects, and patient characteristics. Various types of anesthesia include general, local, regional, spinal, and inhalational.
General anesthesia induces unconsciousness in the whole body, while the others target specific areas or sensations. It is administered to minimize adverse effects, maintain...

01:22Stages of General Anesthesia
Various sedation levels offer significant advantages in facilitating procedural interventions for patients undergoing medical or invasive surgical procedures. These levels span from anxiolysis to general anesthesia, providing a spectrum of sedative effects to cater to specific patient needs. Anxiolysis reduces anxiety and is achieved through minimal sedation, enabling patients to remain awake and responsive while feeling more at ease during the procedure. This level can benefit minor...
01:20Inhalational Anesthetics: Overview
Inhalation anesthetics are drugs that induce general anesthesia upon inhalation. They work by increasing the sensitivity of GABAA receptors or inhibiting NMDA receptors, leading to a decrease in central nervous system activity. The depth of anesthesia can be rapidly adjusted by changing the concentration of the inhaled gas. Some common examples of inhalational anesthetics include volatile liquids like isoflurane, desflurane, sevoflurane and gases like xenon and nitrous oxide. Isoflurane, a...

Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned under...
