Abstract: Respiratory Rate (RR) is a very important physiological parameter to be monitored in both healthy and critical condition, as it gives meaningful information regarding their respiratory system performance as well as condition. Respiratory rate is an important vital sign that can indicate progression of illness but to also predict rapid decline in health. For the purpose, noninvasive monitoring systems are becoming more popular due to the self-evident increase in patient comfort. It can be hard to predict respiratory failure as it can lead to life threatening condition within a short span of time. Thus it necessitates continuous monitoring of respiratory activity and suitable monitoring equipment are developed which could be life-saving. The survey incorporates non-obtrusive strategies and gadgets used to give data about respiratory rate. Many types of respiratory rate monitors have been used for the measurement of the Respiration Rate. This review consists of seven types of Respiration Rate monitors with different sensors. Respiration Rate monitor using Ultrasonic Sensor and Respiration Rate monitor using facial tracking method are the non-contact respiration rate monitoring system. Respiration Rate measurement based on Impedance Pneumography and Respiration Rate measurement are based on the Thoracic Expansion measurement include the sensor that are placed on the thorax. Respiration Rate monitor with MEMS based Capacitive Pressure Sensor, Respiration Rate monitor with temperature sensor, Respiration Rate meter–a low–cost design approach uses sensors that are mounted within the oxygen mask. Thus the Respiratory Rate Monitors discussed in this paper provide optimal result to detect changes in the severity of chronic illnesses.
