CERT unit 3 Flashcards
How many liters of blood does the average person have?
5 liters
There are typically four stages of excessive bleeding. Describe stage 1.
Loss of less than 15% of blood volume. Patient appears normal with a slightly
increased heart rate.
There are typically four stages of excessive bleeding. Describe stage 2.
Loss of 15%-30% of blood volume. Patient’s body is able to compensate for
the loss of blood but may appear agitated or anxious as vital signs rise.
There are typically four stages of excessive bleeding. Describe stage 3.
Loss of 30%-40% of blood volume. Patient becomes unable to compensate
and condition worsens. If left untreated will proceed to irreversible shock. Patient
appears confused.
There are typically four stages of excessive bleeding. Describe stage 4.
Loss of >40% of blood volume. Patient enters irreversible shock. Patient
appears lethargic and death will occur within minutes because of overwhelming and
irreversible damage to vital organs.
vitals for stage 1 severe bleeding. describe the blood loss, HR, BP, Breath rate, and how the patient feels.
less than 15% blood loss. HR normal, less than 100. BP normal. Breath rate normal 14-20. Patient appears normal.
vitals for stage 2 severe bleeding. describe the blood loss, HR, BP, Breath rate, and how the patient feels.
15-30% blood loss. HR fast, greater than 100 BPM. BP slightly low. Breath rate 20-30. Patient may feel anxious.
vitals for stage 3 severe bleeding. describe the blood loss, HR, BP, Breath rate, and how the patient feels.
Blood loss 30-40%. HR very fast, greater than 120 BPM. BP low. Breath rate 30-40. Patient feels confused
vitals for stage 4 severe bleeding. describe the blood loss, HR, BP, Breath rate, and how the patient feels.
Blood loss greater than 40%. HR critical, greater than 140 BPM. BP critical. breath rate greater than 35. Patient feels lethargic.
Describe arterial bleeding speed.
Arteries transport blood under high pressure. Blood coming from an artery will spurt.
describe venous bleeding speed.
Veins transport blood under low pressure. Blood coming from a vein will flow.
describe capillary bleeding speed.
Capillaries also carry blood under low pressure. Blood coming from capillaries will ooze.
How to do the tripod position when seated and standing.
When sitting on a raised platform (e.g., chair, bench): Legs shoulder width
apart, elbows or hands on knees, and leaning forward slightly.
* When standing: Legs shoulder width apart, hands on knees arms straight, and
leaning forward with flat back.
