A normal CPR procedure uses chest compressions and ventilations ... [31]: 8 Recommended compression depth in adults and children is of 5 cm (2 inches), ...
Checking the respiratory rate, depth and rhythm - Normal breathing is between 12 and 20 in a healthy patient, with a regular pattern and depth. If any of these deviate from normal, this may indicate an underlying problem (such as with Cheyne-Stokes respiration) Chest deformity and movement - The chest should rise and fall equally on both sides ...
The guidelines also changed the duration of rescue breaths and the placement of the hand on the chest when performing chest compressions. These changes were introduced to simplify the algorithm , to allow for faster decision making and to maximize the time spent giving chest compressions; this is because interruptions in chest compressions have ...
After defibrillation, chest compressions should be continued for two minutes before another rhythm check. [30] This is based on a compression rate of 100-120 compressions per minute, a compression depth of 5–6 centimeters into the chest, full chest recoil, and a ventilation rate of 10 breath ventilations per minute.

The compression depth and force varies per patient. The chest displacement equals a 20% reduction in the anterior-posterior chest depth. The physiological duty cycle is 50%, and it runs in a 30:2, 15:2 or continuous compression mode, which is user-selectable, at a rate of 80 compressions-per-minute.
Chest compressions were commenced within 10 minutes; The cardiac arrest duration (collapse to arrival at E&TC [ambiguous]) has been < 60 minutes; The patient is aged between 12 and 70 years; There are no major co-morbidities that would preclude return to independent living; The patient is profoundly hypothermic (<32 °C) due to accidental exposure
For humans, the typical respiratory rate for a healthy adult at rest is 12–15 breaths per minute. [10] The respiratory center sets the quiet respiratory rhythm at around two seconds for an inhalation and three seconds exhalation. This gives the lower of the average rate at 12 breaths per minute.
