chest compression

^[1]

Indications

place heel of one hand on chest over sternum with lower edge of hand at upper border of manubrium (guestimate)
place heel of second hand on top of first hand
- alternatively grasp the wrist of the first hand with the second hand
extend elbows (staighten arms) & position shoulders directly above hands
depth: 2.0-2.4 inches, 5-6 cm
rate: 100-120/minute
allow recoil (chest/lung expansion) after each compression
- remove weight/pressure on chest between compressions without repositioning hands
recoil & compression duration should be approximately equal
compression to ventilation ratio 1 person rescue = 30 compressions to 2 breaths
compression to ventilation ratio 2 person rescue (adult) = 30 compressions to 2 breaths
compression to ventilation ratio 2 person rescue (child) = 15 compressions to 2 breaths
