Anaesthesia Foundations MCQs

Capnography is continuous graphical display of carbon dioxide concentration during the respiratory cycle.

ASA physical status is a preoperative classification describing a patient’s systemic health status.

Balanced anaesthesia is use of multiple agents and techniques to achieve hypnosis, analgesia, muscle relaxation and physiological stability.

Preoxygenation is administration of high-concentration oxygen before induction to increase oxygen reserve.

Preoxygenation is administration of high-concentration oxygen before induction to increase oxygen reserve.

Rapid-sequence induction is an induction technique designed to secure the airway quickly while reducing aspiration risk.

Minimum alveolar concentration is the alveolar concentration of an inhaled anaesthetic preventing movement in half of subjects exposed to a standard stimulus.

End-tidal carbon dioxide is the carbon dioxide concentration measured at the end of expiration and used to assess ventilation.

Pulse oximetry is non-invasive estimation of arterial oxygen saturation using light absorption.

Neuromuscular blockade is pharmacological interruption of transmission at the neuromuscular junction to produce paralysis.

Postoperative nausea and vomiting is a common postoperative complication influenced by patient, anaesthetic and surgical factors.

Local anaesthetic systemic toxicity is neurological and cardiovascular toxicity caused by excessive systemic local anaesthetic concentration.
