A cigarette is a small cylinder of finely cut tobacco leaves rolled in thin paper for smoking. The cigarette is ignited at one end causing the cigarette to smoulder and allowing smoke to be inhaled from the other end, which is held in or to the mouth; in some cases, a cigarette holder may be used, as well.
The breathing rate, or the number of times that a person breathes in and out in 1 minute, is often checked by health care professionals to determine the health of a person. The normal breathing rate is between 12 and 18 breaths per minute.
Measurement [edit]. Human respiration rate is measured when a person is at rest and involves counting the number of breaths for one minute by counting how many times the chest rises.An optical breath rate sensor can be used for monitoring patients during a magnetic resonance imaging scan.he typical respiratory rate for a healthy adult at rest is 12â20 breaths per minute. Average resting respiratory rates by age are: 1  birth to 6 weeks: 30â60 breaths per minute. 2  6 months: 25â40 breaths per minute.
