Basic Life Support - Maternal Collapse Flashcards
Self Assessment of Basic Life Support (BLS)
What is the basic life support algorithm ?
DRSABCD
What is the ratio of chest compressions:breaths during CPR?
30:2
What rate (how fast) should the chest compressions be?
100-120
What is the aim of chest compressions?
To circulate blood around the body to achieve venous blood return to the heart
Where should your hands be placed during chest compressions?
Centre of chest
How deep do you compress a chest during CPR for an adult?
A third of the chest
What does a defibrillator do when the pads are on the person?
Analyses the heart rhythm and guides whether to shock or not
How long is a “cycle” or loop of CPR 30:2 ?
A loop or cycle is 2mins of 30 chest compressions to 2 breaths
If the woman is pregnant, what direction should the displacement of the uterus be at?
The displacement of the uterus should be to the maternal left
Approximately (in %) how much more venous return could you achieve with displacing the uterus during CPR?
Approximately 30 - 40% more venous return
What is the code to call in a maternal collapse?
777- Adult code Blue & Obstetric Code
What are some causes of maternal collapse?
Haemorrhage
Septic shock
Cardiac arrest
Amniotic fluid embolism
Toxicity
Pulmonary embolism
Eclampsia
Anaphylactic shock
Stroke
DVT
What does the A in the BLS algorithm stand for ?
Open the AIRWAY
How do you open the adult airway ?
Head tilt, chin lift technique
How long do you check for normal breathing ?
Approximately 10 seconds
What are the four priorities in BLS?
- Early recognition
- Early call for help
- Early chest compressions
- Early use of Defibrillator
What percentage out of the 2500 out of hospital cardiac arrests were witnessed by a “bystander”?
83% .
2.8x increased survival when a witnessed cardiac arrest by a bystander undertaking CPR
