A screen that counts for you when your hands are shaking
Enter the compressions per minute and the length of one cycle, and the tool returns how many compressions that cycle holds, how many sets of 30 compressions to 2 breaths fit inside it, and when each switch falls. Enter the chest width and it also returns the compression depth range for the lateral position in inches.
Guidance recommends 100 to 120 compressions per minute, a depth of one third to one half of the chest width in the lateral position, and 30 compressions to 2 breaths when the airway is not intubated. Let the chest wall recoil fully between compressions and keep compression and relaxation equal in length. These figures follow the RECOVER veterinary CPR consensus guidelines. Current as of October 2026.
This tool does not show hand placement in pictures and does not decide whether the heart has stopped. Any animal that received CPR or a Heimlich maneuver must be examined even if it looks normal afterward, because internal injury, lung bruising and airway swelling can appear hours later. This tool is for reference only and does not replace veterinary care. Contact your veterinarian right away if you notice symptoms or suspect a problem.
Frequently asked questions
One person pushing without a break loses depth and rate without noticing it. Guidance recommends switching on a two-minute cycle, and this tool lists the switch points cumulatively from the cycle length you entered.
If your pet is conscious and only the airway is blocked, start with the airway maneuver: 5 thrusts for a small pet and 5 for a large one. Move to CPR if there is still no response.
No. Rib injury, lung bruising and airway swelling often show up hours later, so an animal that seems recovered on the spot still needs monitoring at a clinic.
