Covidien Respiratory and Monitoring Solutions CMO Scott Kelley said respiration rate is a critical vital sign that can provide an early warning of respiratory complications that may require immediate intervention.

"By looking aspects of ventilation, or the passing of air into and out of the body provides dedicated care teams a more complete picture of a patient’s respiratory status, so they can provide effective treatment and maintain patient safety," Kelley said.
