You and another lifeguard find an unresponsive adult on the locker room floor. The other lifeguard goes to summon ems personnel.

Naddik [55]

Given what we know, we can confirm that the next step to take is to give ventilations to assist the patient in breathing until EMS arrives.

<h3>What are ventilations?</h3>

Ventilation is a form of assisted breathing. This is often done through the use of machines but can be achieved through manual means as well when necessary, such as in this situation. The lifeguard will give ventilation once every 5 or so seconds to bring the patient's breathing rate to a steady 12 times per minute until EMS arrives.

Therefore, we can confirm that the next step to take is to give ventilations at a rate of 12 times per minute to assist the patient in breathing steadily until EMS arrives.

Suppose a certain scale is not calibrated correctly, and as a result, the mass of any object is displayed as 0. 75 kilogram less

r-ruslan [8.4K]

The correlation between the actual masses of a set of objects and the respective masses of the same set of objects displayed by the scale is; 1

<h3>What is the Correct Scale Calibration?</h3>

We are told that a certain scale is not calibrated correctly,

Mass displayed = 0.75 kg (less than its actual mass).

The scale of display = 1

Thus, the correlation between actual mass and displayed mass is 1 due to the fact that correlation is independent of change of origin and scale and correlation between any value and value minus 0.75 will be one.

Thus, the correlation between the actual masses of a set of objects and the respective masses of the same set of objects displayed by the scale is 1.
