Answer: I think they still have to sometimes
Explanation:Answer above
The answer is, "Just noticeable differences."
Weber's law was named after Ernst Weber, a German psychologist. The law postulates that the strength and intensity needed to identify changes in a stimulant correlates to the magnitude of the stimulant. In other words, the more severe a stimulus is, a greater change needs to be made for it to be noticed.
About every 5-6 seconds the patient should be provided ventilations during a respiratory arrest.
A condition known as respiratory arrest is brought on by apnea (cease of breathing) or respiratory malfunction that is so severe that the body cannot support it (such as agonal breathing). A patient with prolonged apnea has ceased breathing for an extended length of time. Respiratory arrest is the term used to describe the circumstance if the heart muscle contraction is unharmed. A sudden halt in pulmonary gas exchange that lasts more than five minutes may irreversibly harm important organs, most notably the brain. Loss of consciousness results from a lack of oxygen to the brain. If respiratory arrest remains untreated for more than three minutes, brain damage is likely, and if it goes untreated for longer than five minutes, death is almost certain.
