Respiratory rate (RR) is a vital sign that can be used to predict adverse outcomes and serious illnesses. It is an indicator of physiological conditions such as hypoxia and hypercapnia and can be used to monitor patient deterioration. RR is often inaccurately measured in hospitals, which can impair the efficacy of early warning scores. However, there have been initiatives to improve RR accuracy, such as adding time-keeping devices to vital sign carts and retraining patient-care assistants. Breathing exercises such as pursed-lip breathing can also help improve respiratory rate by slowing down the breathing pace and relieving shortness of breath.

What You'll Learn
Breathing exercises
Pursed-lip breathing
This technique is taught by pulmonary rehabilitation specialists to individuals with chronic lung diseases such as asthma and COPD. It helps to keep airways open longer, allowing more air to flow in and out of your lungs. This makes each breath more effective and improves oxygen and carbon dioxide exchange.
To practice pursed-lip breathing, sit down in a chair and relax your neck and shoulder muscles. Breathe in slowly through your nose, making sure to keep your mouth closed. Pay attention to how your belly fills up with air. You can put your hands lightly on your stomach, or place a tissue box on it, so you can be aware of your belly rising and falling. Then, breathe out through pursed lips at least twice as long as the inhalation.
Diaphragmatic breathing
Diaphragmatic breathing helps you use the diaphragm correctly while breathing. This technique allows you to use your lungs at 100% capacity to increase lung efficiency. It also offers several benefits, including improving muscle function during exercises and preventing strain, increasing the amount of oxygen in your blood, making it easier for your body to release gas waste from your lungs, reducing blood pressure, and reducing heart rate.
To perform diaphragmatic breathing, relax your shoulders and sit back or lie down. Place one hand on your belly and one on your chest. Inhale through your nose for 2 seconds, feeling the air move into your abdomen and your stomach move out. Your stomach should move more than your chest. Breathe out through pursed lips while pressing on your abdomen.
It is recommended to practice these exercises for about 5 to 10 minutes every day.

Reducing fever
Fever is a common symptom of illnesses like colds, the flu, and other viral and bacterial infections. While fever itself is a natural response of the body to infections, it is essential to monitor your temperature to determine if further action is needed. Here are some ways to reduce a fever:
Rest and Hydration
Getting enough rest and sleep can help support the immune system, allowing your body to fight fever-causing viruses. Activity can raise your body temperature, so resting helps to recover and reduce a fever. Staying hydrated is also crucial when you have a fever. A fever increases body temperature, which can lead to fluid loss through sweating, so drinking water, herbal teas, or electrolyte-rich drinks can prevent dehydration and keep your body functioning.
Medication
Medication is not always necessary, but fever-reducing medications can help. Over-the-counter medicines with active ingredients such as acetaminophen can reduce fever and relieve minor aches and pains. Antiviral medications like baloxavir marboxil (Xofluza), oseltamivir (Tamiflu), peramivir (Rapivab), or zanamivir (Relenza) are recommended for treating the flu and work best within 48 hours of the first symptoms.
Cool Environments
Maintaining a cool environment can help reduce a fever. Keep the room temperature comfortable and cool, using fans or adjusting the thermostat. Wear lightweight and breathable clothing, such as loose-fitting cotton garments, to allow better air circulation and prevent overheating.
Lukewarm Bath
A lukewarm bath can effectively reduce a fever. Soaking in a tepid bath for 10-15 minutes helps cool the body temperature. Avoid using cold water, as it may lead to shivering. A cool, damp washcloth can also be placed on the forehead and the back of the neck to help with fever symptoms.
It is important to monitor fevers, especially in babies and young children. Consult a doctor or pediatrician if a fever lasts several days, is accompanied by severe symptoms, or persists despite home remedies.

Lowering stress
Being in the hospital can be stressful. Being away from your friends and family may make you feel lonely or scared. Here are some tips to help you manage stress while you’re in the hospital.
Identify the cause of your stress
If possible, try to identify the cause of your stress. Evidence shows that helping others through activities such as volunteering or community work can make you more resilient. If you don't have time to volunteer, try to do someone a favour every day. It can be something as small as helping someone cross the road.
Stay connected with friends and family
You can call, text, or video chat with friends and family even when you cannot be with them physically. You may find it helpful to plan daily calls with them that you can look forward to. If you feel up to it, you can try video chatting while playing a game together.
Adopt relaxation techniques
Relaxation techniques such as deep breaths, stretching, and meditating can help you manage stress. You can also try guided imagery and other relaxing videos.

Improving accuracy of respiratory rate measurement
Respiratory rate (RR) is a vital sign that is routinely measured for hospitalized adults. It is a strong predictor of adverse events and is a key component of several widely used risk prediction scores, including the systemic inflammatory response syndrome (SIRS). Despite its clinical utility, RR is often inaccurately measured. One reason for this is that RR measurement, unlike other vital signs, is not automated. The gold-standard technique for measuring RR is the visual assessment of a resting patient, which is time-consuming. As a result, clinical staff frequently approximate RR through brief observation.
To improve the accuracy of RR measurement, a low-cost, low-tech QI initiative can be implemented. This may involve adding time-keeping devices, such as stopwatches, to vital sign carts and retraining patient-care assistants on a modified workflow that includes concomitant RR measurement during automated blood pressure measurement. This approach has been shown to improve the accuracy of RR measurements and reduce the time required to complete vital sign checks.
Another method to improve accuracy is to utilize mobile devices with specific applications designed for RR measurement. This approach has been tested in children and has shown promising results in terms of both accuracy and efficiency. The use of a mobile app can provide a more robust and quick method for healthcare workers to measure RR.
Additionally, it is important to consider the factors that can affect a person's respiratory rate when measuring and interpreting RR. These factors include age, activity levels, fever, anxiety, heart problems, and medical conditions. For example, respiratory rates in elderly individuals tend to be higher than those of younger adults. Furthermore, a respiratory rate of over 20 breaths per minute in an adult may indicate an underlying health issue.
By combining the use of time-keeping devices, staff retraining, and considering relevant factors, the accuracy of RR measurement can be significantly improved in a hospital setting. This, in turn, can lead to better patient outcomes and more effective risk prediction.

Monitoring and documentation of respiratory rate
Respiratory rate (RR) is a fundamental vital sign that is sensitive to different pathological conditions, such as adverse cardiac events, pneumonia, and clinical deterioration. It is also influenced by stressors like emotional stress, cognitive load, physical effort, and exercise-induced fatigue. As a result, accurate monitoring and documentation of respiratory rate are crucial for patient care.
In a hospital setting, respiratory rate is typically measured manually by counting the number of breaths a person takes in a one-minute period while at rest. This manual process is often subject to human error and can be time-consuming, leading to inaccuracies in measurement. To address this, some hospitals have implemented low-cost, low-tech interventions, such as adding time-keeping devices to vital sign carts and retraining patient-care assistants on modified workflows that include concomitant RR measurement during automated blood pressure checks. These interventions have shown improvements in accuracy and efficiency.
The gold standard technique for measuring RR is the visual assessment of a resting patient for one minute. This can be done by watching the person's chest rise and fall, counting one inhalation (chest rises) and one exhalation (chest falls) as one complete breath. It is important to ensure the patient is unaware they are being monitored to obtain an accurate reading. Additionally, RR can be measured for 30 seconds and then multiplied by two to get the rate per minute.
Accurate documentation of RR is crucial as it helps improve patient outcomes. Any changes or anomalies in RR can indicate that a patient is struggling to maintain homeostasis. For example, an increase in RR may be a sign of hypoxia (low oxygen levels in the cells) or hypercapnia (high carbon dioxide levels in the bloodstream). On the other hand, a decrease in RR may be indicative of metabolic alkalosis. Therefore, timely recognition and documentation of RR changes enable prompt medical action and can prevent adverse patient outcomes.
To improve the accuracy and efficiency of RR monitoring, healthcare providers can utilize technological solutions such as strain sensors, touchless monitoring technology, and biofeedback systems. Strain sensors can be embedded into straps, bands, or t-shirts, providing real-time data on chest wall movements. Touchless monitoring technology, such as depth-sensing camera systems, allows for continuous, non-invasive monitoring of RR. Additionally, biofeedback systems like RESPeRATE® can help patients with hypertension or panic disorders regulate their breathing through auditory feedback, reducing their respiratory rate.

Frequently asked questions
Respiratory rate (RR) is the number of breaths someone takes per minute. It is considered a vital sign and is routinely measured for hospitalized adults.
A normal respiratory rate for healthy adults is between 12 and 20 breaths per minute. Children tend to breathe faster than adults, and their respiratory rate decreases as they age.
Tachypnea is the medical term for an elevated respiratory rate, which is usually shallow and rapid. Bradypnea refers to abnormally slow breathing. Dyspnea is the term for shortness of breath, which can occur with elevated, normal, or decreased respiratory rates.
An abnormal respiratory rate can be caused by various factors, including injuries, exercise, emotional stress, cognitive load, mood, and underlying health conditions such as anxiety, fever, heart problems, or respiratory distress.
To improve respiratory rate accuracy in hospitals, initiatives have been proposed to address workflow inefficiencies and encourage appropriate responses to abnormal respiratory rates. This includes accurate documentation, the use of time-keeping devices, and educating healthcare professionals on the importance of RR as a marker of serious illness. Additionally, breathing exercises such as pursed-lip breathing can help slow breathing rates and improve lung efficiency.
