The correct chest compression depth is about 1½ inches. The correct rate of compressions is 100 to 120 per minute.
According to current basic life support recommendations, a compression depth of one third to one half of the anteroposterior chest diameter should be used for newborn and toddler resuscitation. A study was done to determine the actual compression depths in newborns and kids. 36 newborns (1 year old) and 38 kids (aged 1 to 8 years) had their chest computed tomography scans analyzed. Chest computed tomography scan measurements of the anteroposterior diameter were taken from the anterior skin perpendicular to the skin on the posterior thorax, either at the interni pple line or the center of the lower half of the sternum.
The mean age was 3.6 months for the newborn group (25 boys and 11 girls). The average age of the 21 boys and 17 girls in the child-age group was 4.0 years. When current criteria were followed, compression depths ranged from 3.4 to 5.1 cm for infants and 4.4 to 6.6 cm for children. The compression depths at the interni pple line compared to the lower half of the sternum were same. These 2 were found beneath intrathoracic structures that suggested similar compression landmarks. In comparison to the suggested compression depths for adults (3.8-5.1 cm).

Answer:
Native peoples of America had no immunity to the diseases that European explorers and colonists brought with them. Diseases such as smallpox, influenza, measles, and even chicken pox proved deadly to American Indians.
Explanation:
De Soto's path through the Mississippian cultures of what is now the southeast United States spread disease among the local inhabitants, diminished native food supplies, and led to a reduction in native populations. Resisting tribes found themselves under vicious attack by Spanish soldiers.
