How to Count Respirations in 15 Seconds

By Your Health Magazine Health Information Team

To count respirations for 15 seconds, watch the person’s chest or abdomen and count each complete rise-and-fall cycle as one breath. After 15 seconds, multiply the number of breaths by four to estimate breaths per minute. For example, five breaths in 15 seconds equals an estimated respiratory rate of 20 breaths per minute.

How to Count Respirations for 15 Seconds

1. Let the person rest. They should sit or lie comfortably and avoid talking, walking, or exercising immediately before the measurement.
2. Use a timer. Choose a stopwatch, phone timer, or clock that clearly displays seconds.
3. Watch the chest or abdomen. Look for its natural rise during inhalation and fall during exhalation.
4. Count complete breaths. One rise and one fall together count as one breath. Do not count the inhale and exhale separately.
5. Count for exactly 15 seconds. Start with the first clearly observed breath after beginning the timer.
6. Multiply the count by four. The result is the estimated respiratory rate in breaths per minute.

If you are counting someone else’s respirations, try not to draw attention to the measurement. People may unintentionally change their breathing when they know it is being watched. One option is to continue holding the person’s wrist after checking their pulse while quietly observing the chest.

Is a 15-Second Count Accurate?

A 15-second count provides a quick estimate, but it is less precise than counting for a full minute. Because the result is multiplied by four, missing or adding just one breath changes the estimated rate by four breaths per minute. That difference can matter when a person’s rate is near the edge of an expected range.

For a more dependable measurement, count for 60 seconds. A full-minute count is especially appropriate when:

• Breathing is irregular, unusually shallow, or interrupted by pauses.
• The person appears ill or is having difficulty breathing.
• You are measuring an infant or child.
• A healthcare professional has asked you to track respiratory rate.
• The 15-second result seems unusually high or low.
• You are using the result to decide whether to contact a healthcare professional.

Johns Hopkins Medicine’s guidance on vital signs describes respiratory rate as the number of breaths taken per minute and recommends measuring it while the person is at rest.

What Is a Normal Resting Respiratory Rate?

Published reference ranges vary slightly. MedlinePlus lists 12 to 18 breaths per minute as a typical resting range for the average healthy adult. A single number should not be interpreted by itself, however. Age, health conditions, recent activity, symptoms, and the person’s usual breathing pattern all provide important context.

Respiratory rates are normally faster in infants and young children, and expected ranges change with age. Do not apply an adult range to a child. If you are monitoring a child because of illness or on a clinician’s instructions, count for a full minute and follow the age-specific guidance provided by the child’s pediatrician.

Recent exercise, fever, pain, anxiety, and illness may increase breathing rate. Sleep and certain health conditions or medications may slow it. Allow the person time to settle after activity before measuring a resting rate.

Look Beyond the Number

Respiratory rate is only one part of evaluating breathing. While counting, also observe whether the breaths are regular and whether the person seems to be working harder than usual. Concerning features may include:

• Gasping, grunting, wheezing, or other unusual breathing sounds
• Very shallow breaths or long pauses
• Nostrils widening with each breath
• Skin pulling inward between or beneath the ribs
• Difficulty speaking in complete sentences
• Uneven movement of the chest
• New sleepiness, confusion, or agitation

A rate that falls within a typical numerical range does not rule out a breathing problem. Symptoms and visible effort can be more important than the calculated number. Respiratory rate also cannot identify the cause of abnormal breathing or replace a medical examination.

Tips for a More Reliable Reading

• Measure when the person is quiet and comfortable.
• Use the same position and conditions when comparing readings over time.
• Repeat an unexpected result using a full 60-second count.
• Record the date, time, rate, symptoms, and relevant circumstances, such as fever or recent activity.
• Follow any monitoring instructions supplied by the person’s healthcare team.

If you are trying to count your own respirations, place a hand lightly on your upper abdomen and feel each rise and fall. Be aware that concentrating on breathing may alter its natural rhythm, so a measurement taken by another person may be more representative.

When to Seek Care

Contact a healthcare professional if a resting respiratory rate remains noticeably different from the person’s usual rate, repeatedly falls outside the range their clinician provided, or occurs with fever, cough, wheezing, pain, unusual tiredness, or worsening illness. A primary care clinician, pediatrician, or pulmonary specialist can assess the rate in context and determine whether further evaluation is needed.

Call 911 for sudden or severe trouble breathing, blue or gray lips or skin, confusion, loss of consciousness, or an inability to speak because of breathlessness. The National Heart, Lung, and Blood Institute identifies sudden breathing difficulty, confusion, and bluish skin or lips as emergency warning signs. Do not delay emergency assistance to complete a 15-second respiratory count.
