14 topics with concise breakdowns: definitions, key facts, and class questions.
This chapter is dedicated to critical conditions where every second counts, and the patient's life depends on the physician's correct actions. It compiles basic emergency care algorithms that every medical professional must know, regardless of their specialty.
The section covers in detail the pathophysiology and clinical presentation of terminal states, modern cardiopulmonary resuscitation protocols (including artificial ventilation and cardiac massage), as well as diagnostic and management principles for various types of shock: traumatic, hemorrhagic, and anaphylactic. Special attention is paid to acute vascular failure and specific emergencies: drowning, electrical injury, heat stroke, and sunstroke.
During practical classes and examinations, instructors evaluate knowledge of the basic CPR algorithm most strictly, along with the ability to quickly differentiate types of shock and accurately state the dosages of first-line drugs (e.g., adrenaline in anaphylaxis). Thorough mastery of this material is the foundation of clinical safety.
How much time does a physician have to diagnose clinical death?
The time to establish a diagnosis must be kept to an absolute minimum. Clinical death itself lasts only 3–5 minutes, after which (in 5–6 minutes) irreversible CNS changes and biological death ensue.
Can CPR be performed without a medical education?
Yes, the first three steps (ensuring airway patency, artificial ventilation, cardiac massage) can be performed out-of-hospital by anyone with appropriate practical skills.
How to determine that ventilation is being performed effectively?
The main criterion for effectiveness is chest excursion. The chest should visibly expand during air insufflation and deflate during passive exhalation.
Where exactly is the hand placement point during closed-chest massage?
Hands must be positioned in the lower third of the sternum, approximately 2 centimeters above the xiphoid process.
What is the compression-to-ventilation ratio if I am performing resuscitation alone?
You need to alternate 15 chest compressions with 2 ventilations (15:2).
What is hemodynamic conflict in shock?
This is a critical mismatch between the circulating blood volume and the total capacity of the vascular bed. It is this imbalance that leads to a drop in cardiac output and a global breakdown of microcirculation.
