New vital sign monitoring system

New Vital Sign Monitoring System may improve the care for hospitalized patients

A recent study indicated that a newly designed Vital Sign Monitoring System can improve patient safety in medical and surgical units without an abundance of unnecessary alarms.

When the system was installed for four weeks in two medical/surgical units, one in Utah and one in Alabama, 92% of the nurses agreed that the number of alarms and alerts were appropriate and 100% agreed that the monitor provided valuable patient data that increased patient safety. On average, both units experienced 10.8 alarms per patient, per day. The system continuously monitors patients’ oxygen saturation levels, heart rate, blood pressure, and respiration rate.


“We are very excited to be using this advanced technology. Continuous monitoring of our patients is revolutionizing the way we care for our patients,” said Pam Booker, senior author of the Journal of Clinical Nursing study. “Our nurses love the ability to keep a closer eye on their patients, and this system has the ability to notify the nurses when vital signs change, no matter where they are in the hospital.”

Eight vital signs:
1. Temperature. Physiology: Controlled by AgeCore temperature differsthe hypothalamus.
2. Pulse. Physiology: Reflects circulating volume and strength of contractility.
3. Blood pressure. Physiology: Regulated by vasomotor centre in the medulla.
4. Respiratory rate. Physiology: Controlled by the respiratory centres in the medulla and pons.
5. SpO2. Physiology: Reflects the peripheral saturation of haemoglobin by O2.
6. Pain. Physiology: Detected by peripheral nerve fibers; interpreted by thalamus and cerebral cortex.
7. Level of consciousness. Physiology: Controlled by reticular activating system in the brain stem.
8. Urine output. Physiology: Produced by kidneys.
