Flashcards
Class I Hemorrhagic Shock
Class I Hemorrhagic Shock
The first stage of hemorrhagic shock characterized by a blood loss of 0-15% and minimal symptoms. The patient may feel slightly anxious, but their vital signs remain relatively normal.
Class II Hemorrhagic Shock
Class II Hemorrhagic Shock
The second stage of hemorrhagic shock, involving a blood loss of 15-30%. The patient may experience increased anxiety, a faster heart rate, and a slightly decreased pulse pressure.
Class III Hemorrhagic Shock
Class III Hemorrhagic Shock
The third stage of hemorrhagic shock, characterized by a blood loss of 30-40%. The patient shows significant symptoms including increased anxiety, confusion, significantly lowered blood pressure, and a very fast heart rate.
