An evaluation of respiratory rate for the differentiation of the severity of illness in babies under 6 months found it not to be very useful. Approximately half of the babies had a respiratory rate above 50 breaths per minute, thereby questioning the value of having a "cut-off" at 50 breaths per minute as the indicator of serious respiratory ...
Average respiratory rates vary between ages, but the normal reference range for people age 18 to 65 is 16–20 breaths per minute. [4] The value of respiratory rate as an indicator of potential respiratory dysfunction has been investigated but findings suggest it is of limited value.
In addition to measuring the patient's respiratory rate, the examiner will observe the patient's breathing pattern: A patient with metabolic acidosis will often demonstrate a rapid breathing pattern, known as Kussmaul breathing. Rapid breathing helps the patient compensate for the decrease in blood pH by increasing the amount of exhaled carbon ...
Breathing - assess respiratory rate, respiratory effort, lung sounds, airway sounds, chest movement, oxygen saturation via pulse oximetry Circulation - assess heart rate, heart rhythm, pulses, skin color, skin temperature, capillary refill time, blood pressure
A respirometer is a device used to measure the rate of respiration [1] of a living organism by measuring its rate of exchange of oxygen and/or carbon dioxide. [2] They allow investigation into how factors such as age, or chemicals affect the rate of respiration. [3]
A RSBI score of less than 65 [3] indicating a relatively low respiratory rate compared to tidal volume is generally considered as an indication of weaning readiness. A patient with a rapid shallow breathing index (RSBI) of less than 105 has an approximately 80% chance of being successfully extubated, whereas an RSBI of greater than 105 virtually guarantees weaning failure.
