Vital signs monitors are used in hospitals to evaluate a patient's health and track their progress toward recovery. One of the key measurements these monitors provide is the respiratory rate, or RR, which is the number of breaths a patient takes per minute. This is a vital indicator of a patient's health, and one of the first signs of deterioration. A normal RR value is between 12 and 20 breaths per minute for adults at rest, and anything under 12 or over 25 breaths per minute is considered abnormal.

What You'll Learn

RR stands for respiratory rate
Respiratory rate (RR) is a vital sign routinely monitored by medical professionals and healthcare providers. RR is one of the first vital signs to indicate the deterioration of a patient's condition. It is reported in breaths per minute, with normal values between 12 and 20. However, this number isn’t very accurate, especially as the patient’s breathing rate fluctuates.
RR can be monitored in two ways: using sensors attached to the patient's body, or through contactless video monitoring. The former involves attaching small sensors to the patient's body to carry information to the monitor. These sensors can be patches that stick to the skin or clipped onto a finger. The latter method, which is less accurate, involves monitoring the patient's breathing rate through video data.
Vital signs monitors enable clinicians to evaluate their patients quickly and efficiently, both inside and outside the hospital setting. They collect a patient’s real-time data, help healthcare professionals identify signs of deterioration, and reduce manual errors by automatically sending data to the patient's electronic medical record.
If a patient’s respiratory rate is under 12 or over 25 breaths per minute while they lay in bed, doctors consider their breathing abnormal. A rate of 20, for example, may indicate that the patient is experiencing distress caused by pain or anxiety. When a patient's RR falls outside healthy levels, the monitor will alert clinicians through a beeping sound or flashing lights.

It is the number of breaths per minute
A patient's respiratory rate (RR) is the number of breaths they take per minute. It is one of the first vital signs that indicate the deterioration of a patient's condition. The average respiration rate for a resting adult is between 12 and 16 breaths per minute, but this can vary depending on factors such as anxiety and heart failure. Doctors consider breathing abnormal if the respiratory rate falls below 12 or rises above 25 breaths per minute.
Vital signs monitors enable clinicians to quickly and efficiently evaluate their patients' health both inside and outside the hospital. They collect real-time data, help identify signs of deterioration, and reduce manual errors by automatically sending data to the patient's medical record. The primary function of a vital signs monitor is to alert medical staff when a patient's vitals fall below safe levels.
The vital signs monitor will display the patient's respiratory rate in the RR box. The RR box may show a number between 12 and 20, indicating the number of breaths the patient takes per minute. This number may not be very accurate, especially as the patient's breathing rate fluctuates.
In addition to the RR box, the vital signs monitor may also display the respiratory waveform (RESP). This waveform can help clinicians monitor respiratory issues such as apnea or dyspnea. The monitor will alert clinicians with a beeping sound or flashing lights if the patient's vital signs fall outside the healthy range.

An abnormal RR reading could indicate distress
On a hospital monitor, RR stands for respiratory rate, which is the number of breaths a person takes in a one-minute period. The average respiratory rate for a healthy adult is between 12 and 18 breaths per minute. When a patient is at rest, the average respiration rate is between 12 and 16 breaths per minute.
In addition to distress, an abnormal RR reading could also indicate that the patient is struggling to maintain homeostasis. An abnormal RR reading can be an early indicator of physiological conditions such as hypoxia (low levels of oxygen in the cells), hypercapnia (high levels of carbon dioxide in the bloodstream), metabolic and respiratory acidosis. For example, respiratory alkalosis occurs when the blood pH level is out of balance, which can be caused by breathing too fast.
Vital signs monitors are important tools in healthcare settings, enabling clinicians to quickly and efficiently evaluate their patients' health. They collect real-time patient data, help identify signs of deterioration, and reduce manual errors by automatically sending data to electronic medical records. When a patient's vital signs fall outside healthy levels, the monitor will typically alert caregivers by making a beeping sound or flashing lights.

RR is one of the first vital signs to indicate deterioration
Respiratory rate (RR) is a vital sign that indicates how many breaths a person takes per minute. The average respiratory rate for a healthy adult at rest is between 12 and 18 breaths per minute. RR is displayed on a vital signs monitor, which is a device used by healthcare professionals to evaluate a patient's health. These monitors can be used in or outside a hospital setting and provide real-time data on a patient's condition.
An increase in RR can be an early warning sign of clinical deterioration. A respiratory rate of over 20 breaths per minute may indicate that a patient is unwell, and a rate of over 24 breaths per minute could signal a critical condition. However, RR is often overlooked as a vital sign, and it is frequently the least monitored or automated vital sign in medical settings. This may be due to the time-consuming and error-prone nature of manually counting chest-wall movements to measure RR.
To address the challenges of manual RR measurement, healthcare facilities can employ continuous respiratory monitoring using contactless remote patient monitoring (RPM) systems. These systems can help clinicians detect early signs of deterioration and initiate timely interventions, potentially reducing preventable hospitalizations and improving patient outcomes. By enhancing nursing education and implementing early detection protocols, healthcare providers can better utilize RR as a vital sign to identify patient deterioration.

Vital signs monitors are portable and wireless
Vital signs monitors are now portable and wireless, enabling clinicians to evaluate their patients quickly and efficiently, both inside and outside the hospital. These devices collect a patient’s real-time data, help healthcare professionals identify signs of deterioration, and reduce manual errors by automatically sending data to the electronic medical record. The device’s sensors can be clipped to a patient’s fingers or patched to the skin, delivering information to the monitoring device when connected to a patient.
The primary function of a vital signs monitor is to alert medical staff when a patient’s vitals fall below established safe levels. For example, a patient’s respiratory rate is the number of breaths they take per minute. The average respiration rate for an adult at rest is 12 to 16 breaths per minute. If a patient’s respiratory rate is under 12 or over 25 breaths per minute, doctors consider their breathing abnormal. The patient’s respiration rate is displayed in the RR box of the vital signs monitor.
More advanced models also show how much oxygen the blood is carrying or how fast the patient is breathing. Some can even show how much pressure is on the brain or how much carbon dioxide the patient is breathing out. The monitor will make certain sounds if any of the vital signs fall below safe levels. Heart rate, blood pressure, and body temperature are also displayed on the most basic monitors.
The field of wireless wearable medical devices is developing rapidly. Single-use wearable devices for vital signs monitoring include wrist and arm bands, watches, Holter devices, and patches. Wearable wireless sensors include the BioSensor, Healthdot/HealthPatch, Sensium, and VitalPatch, among others. They are embedded with small sensors that allow for continuous patient monitoring. These devices can be medical grade (intended for use by trained health care providers only) or consumer grade. Notifications are sent to the health care provider when readings fall outside of preset thresholds to alert them to potential deterioration.
