 * I have no way of making the heart variables private set, so the onus is on you dear contributor not to set them by event. I've set aside three variables for you to touch instead.
 * "recent_pump" controls interactions with things like CPR, stabilizer harness
 * "pulse_mod" at this step is equal to 1x, use this to insert any desired pump rate modifications.
 * "min_efficiency" controls the Floor of heart pump rate, particularly when its stopped. Default is 0.5x with CPR, 0.3x without

/**
 * Raised on an entity whose blood is attempting to circulate oxygen through the body.
 * "blood_volume" is the percentage of blood vs max blood, between 0 and 100. Don't put it outside those bounds.
 * "blood_volume_mod" is the ratio of oxygen loss to health loss, representing how damaged the circulatory system is as a whole. You can safely multiply against this to include your own modifiers.
 * "oxygenated_add" represents the ratio of internal blood oxygenation to external oxygenation. Such as from Dexalin and Dexplus. Defaults to 0, so additive identity applies.
