Study Notes
Infant CPR
- Infant depth for compressions is 1.5 inches.
Compression to Ventilation Ratio
- Ratio of compression to ventilation remains at 30:2 for adults with one or two rescuers.
- For children and infants with 2-person rescue, the ratio changes to 15:2.
Switching Compressors to Ventilation
- Switch after 2 minutes or 5 cycles.
Possible Causes of Asystole
- Tension pneumothorax caused by the accident.
- Cardiac tamponade, hypoxia, hypovolemia, acidosis, hypothermia.
- Pulmonary embolus if they throw a clot from a fracture.
Fluids for Resuscitation
- 0.9 normal saline.
- Lactated Ringer's (LR).
Bag Valve Mask Device
- Note the rise and fall of the person's chest with each breath.
CPR Ratio and Initiation
- Compression to ventilation ratio is 30:2.
- CPR should be started immediately when a person becomes unconscious, is not breathing, and is pulseless.
Rhythm Identification
- Sinus tachycardia with no pulse and not breathing is PEA.
- Asystole rhythm has no pulse and is not breathing.
Medication for Asystole
- Epinephrine 1mg IV (1mg of a 1:10,000 concentration) every 3-5 minutes.
5 H's and T's for Asystole
- Hypovolemia, hypoxia, hydrogen ions, hypo/hyperkalemia, hypothermia/hyperthermia.
- Tension pneumothorax, tamponade (cardiac), toxins, cardiac thrombosis, pulmonary thrombosis.
CPR Compressions per Minute
- At least 100 compressions per minute with the goal of 100-120 compressions per minute without pauses for ventilation.
Compression Depth
- Adult compression depth is at least 2 inches to no more than 2.4 inches on the lower third of the chest.
- Child compression depth is 2 inches.
- Infant compression depth is 1.5 inches.
