Risks and Medical Emergencies

Study guide

Unit 10 is the unit with the least room for approximation. It covers recognition of the deteriorating or collapsed patient, basic life support, the drugs and equipment a practice must be able to reach immediately, and the specific emergencies that occur in a dental setting.

Recognition and assessment

Before any intervention comes a structured assessment, applied in the same order every time.

• A systematic approach prevents a serious problem being missed because a more obvious one was treated first.
• Danger, response, airway, breathing and circulation give a reliable order of priorities.
• Early recognition of deterioration matters more than any single intervention that follows.
• Calling for help early is part of the response, not an admission of failure.

Basic life support and defibrillation

Follow current Resuscitation Council UK guidance, which is updated periodically — always train against the current version.

• Chest compressions are started promptly for a patient who is unresponsive and not breathing normally.
• An automated external defibrillator is applied as soon as it is available and its prompts are followed.
• Interruptions to compressions are minimised, because perfusion falls immediately when they stop.

Emergency preparedness

Equipment that cannot be found, or has expired, is equipment the practice does not have.

• Emergency drugs and equipment are checked on a defined schedule and the checks are recorded.
• All staff, clinical and non-clinical, are trained in their role in an emergency, and that training is repeated.
• Everyone should know where the emergency kit and the defibrillator are without having to look.

Specific emergencies and paediatric modifications

The presentations most likely to occur in a dental practice, and how the approach changes for a child.

• Anaphylaxis, hypoglycaemia, angina and myocardial infarction, asthma, epileptic seizure, syncope and choking each have a recognisable presentation and a defined first response.
• Distinguishing between presentations matters because the immediate treatments differ substantially.
• Paediatric resuscitation differs from adult in defined ways, reflecting the more commonly respiratory cause of arrest in children.

In the exam Questions here test recognition and sequence: which emergency is being described, and what you do first. Learn the presentations well enough to tell them apart, and learn the first action for each — that pairing is where most of the marks are.
