Respiratory rate monitors are medical devices designed to continuously measure and display a patient's breathing rate, typically expressed in breaths per minute. While a basic vital sign, an accurate and continuous respiratory rate can provide crucial insights into a patient's respiratory status and overall health. These monitors can utilize various technologies, including impedance pneumography (detecting changes in chest impedance during breathing), capnography (measuring exhaled CO2), or acoustic sensors. Monitoring respiratory rate is essential in critical care, post-operative recovery, and for patients with conditions like asthma, COPD, or sleep apnea, as changes can indicate worsening respiratory function, pain, or sedative overdose. Continuous monitoring helps healthcare providers detect subtle changes early, enabling timely intervention to prevent respiratory distress or failure and ensuring patient safety.
