respirations The breaths a person takes, counted per minute; the act of breathing and the count of it. Full entry → are the breaths a person takes per minute — the count of each rise and fall of the chest. For a resting adult, the usual reference range is about 12 to 20 breaths per minute, though sources give slightly different edges and ranges vary with age and activity. Each breath has two parts: inhalation Breathing in: the chest expands and air moves into the lungs. Full entry →, breathing in, and exhalation Breathing out: the chest relaxes and air moves out of the lungs; also called expiration. Full entry →, breathing out. When nurses check respirations they look at rate In respiratory assessment, how many breaths a person takes per minute. Full entry →, depth How full each breath is — whether breathing is shallow or deep. Full entry →, and pattern The rhythm of breathing — whether breaths come at regular or irregular intervals. Full entry → — and they count quietly, because people who know they are being watched may breathe differently.
Why this matters
Of all the vital signs The basic measures of body function — temperature, pulse, respirations, and blood pressure — used to check a person's condition. Full entry →, respirations are the easiest to miss: no thermometer, no cuff, just a quiet count of the chest rising and falling. Yet the count is information — a resting adult breathing 28 times a minute is telling you something a pulse or temperature may not. Changes in breathing can be the first signal of trouble, and the way a person breathes — fast or slow, shallow or deep, regular or irregular — adds detail no other vital sign gives. For students, learning to count respirations well, without making the patient self-conscious, is an early professional skill that shows up on clinical checklists and licensing exams.
The college version
A working definition: the breath count
Respirations are the breaths a person takes per minute. The National Library of Medicine's MedlinePlus describes the respiratory rate The number of breaths taken in one minute. Full entry → as the measure of your breathing, and the OpenStax Clinical Nursing Skills text defines it as the breaths per minute. The word is used two ways in care settings: it is the act of breathing itself, and it is the count — how many times a person breathes in one minute. Each complete breath is one cycle: the chest rises, the chest falls. When a nurse records 18 on a vital-signs flow sheet, the entry means the patient breathed 18 times during the minute counted. Respirations are one of the four classic vital signs — temperature, pulse, respirations, and blood pressure — the basic measures of body function caregivers track to see how a person is doing.
The reference range, with the honest caveat
For a resting adult, the usual reference is about 12 to 20 breaths per minute. OpenStax's Clinical Nursing Skills gives the adult range as 12 to 20; MedlinePlus lists 12 to 18. The two references agree closely and differ only at the upper edge — a fair warning against treating any single number as sacred. The honest note is this: normal depends on who is breathing. Newborns breathe 30 to 60 times a minute, toddlers 20 to 30, school-age children 14 to 22, and the OpenStax text notes that rates gradually shift to the adult range in late childhood or early adolescence. Activity moves the count too: breathing speeds up with hard exercise and settles back down at rest. A count outside the adult range is a cue to look closer and report — a signal, not a diagnosis.
The two parts of a breath
Each breath has two named parts. Inhalation is breathing in: the chest expands and air moves into the lungs. Exhalation is breathing out: the chest relaxes and air moves out. The OpenStax respiratory-system section states the pair plainly as inhalation (breathing in) and expiration (breathing out); exhalation and expiration are the same word, and you will hear both in practice. In the vital-signs room the nurse need not analyze how the lungs do their work; that depth belongs to the biology classroom. What matters here is recognizing the cycle — one rise, one fall — because the count is built from complete cycles, not from single movements.
What to notice: rate, depth, and pattern
When a nurse checks respirations, three features describe what is happening. Rate is the count — how many breaths per minute. Depth is how full each breath is: shallow breaths barely move the chest, while deep breaths move it clearly. Pattern is the rhythm — whether breaths come at regular intervals or irregularly. The OpenStax skill text lists exactly these: the breaths per minute, the rhythm, and the depth of respiration. All three matter together. A patient can breathe 16 times a minute — a perfectly ordinary rate — and still be breathing so shallowly that the chest barely moves, which is why a number alone never tells the whole story. Unlabored breathing, the text notes, is quietly audible at most; a normal breath makes little sound.
What changes the count
Breathing responds to the body's demands, and everyday forces move the count. Exercise raises it: MedlinePlus notes that mild breathing changes can come from something as simple as hard exercise. Emotion moves it too — the OpenStax text lists anxiety and fear among the causes of a faster rate. Illness can change it in either direction, and MedlinePlus warns that slow or fast breathing can be a sign of a serious breathing problem. Pain changes it as well: the OpenStax text notes that shallow breathing occurs with pain. None is mysterious — each is the body adjusting — but every one is information. The nurse's job is to notice the change, connect it to what the patient is doing or feeling, and record what was actually seen.
The quiet count
Respirations are counted without the patient noticing, and the reason is honest and practical. The OpenStax skill text explains that there is no need to let the patient know the respiratory rate is being obtained, because the knowledge could cause the patient to unknowingly alter their breathing pattern. Breathing is unusual among the vital signs: it is partly voluntary. People can hold their breath, sigh, or breathe faster on purpose, and a patient who knows the count is happening may do exactly that without meaning to. So the nurse uses a small sleight of hand: after counting the pulse, she keeps her fingers on the wrist and shifts her gaze to the chest, watching it rise and fall while she counts. The patient sees a nurse finishing the pulse check; the nurse gets an accurate number.
The quiet vital sign
Here is the reality check. Temperature needs a thermometer, blood pressure needs a cuff, and the pulse needs fingers on a wrist — but respirations need nothing but observation, which makes them the quietest of the vital signs and the easiest to skip. The quiet has a cost: because nothing beeps and no number pops up on a screen, the count can be recorded without being truly taken. The remedy is the same as for every vital sign: take it deliberately, every time. MedlinePlus calls the respiratory rate the measure of your breathing — and the measure is only as good as the looking. A patient's breaths per minute, noticed carefully, are a stream of information: the rate, the depth, the pattern, and what they change with.
Eli explains
The same idea, in plain words
Explain it like I’m 10
Respirations are simply the breaths you take — one breath in, one breath out — and the count of those in a minute. When a nurse checks them, she is really counting how often your chest rises and falls. Most adults at rest breathe about 12 to 20 times a minute, though babies breathe much faster and a runner breathes faster than someone sitting still. The nurse also notices whether the breaths are full or shallow and whether they come in a steady rhythm. The trick is that people change their breathing when they know it is being watched, so nurses count quietly, as if they were still finishing the pulse check.
Picture it like this
Counting respirations is a little like birdwatching. A bird that notices you watching freezes, calls, or flies — you no longer see how it behaves on its own. So you watch from the corner of your eye, pretending to do something else. The nurse does the same: fingers resting on the wrist as if the pulse count were still going, eyes on the chest, counting each rise and fall. The patient, like the bird, does not know he is being observed, so the nurse gets the true behavior — the real breathing, unaltered by being watched.
Where the picture stops working
A startled bird flies away for good, but a patient's breathing settles back to normal once he stops thinking about it — the change is brief, not permanent. Birdwatchers hide to see nature untouched; nurses count quietly only to get an accurate number, and the moment the count is done they can talk openly about breathing. And unlike a bird, a patient breathes on purpose when he chooses — which is exactly why the quiet count exists.
Worked example
Priya, a first-year nursing student, is taking vital signs on Mr. Hale, who is resting after a morning procedure. She counts his pulse for a stretch of time, then keeps her fingers on his wrist and shifts her gaze to his chest, watching it rise and fall as she counts. She records each complete cycle — one rise, one fall — as a single breath. In a minute he breathes 18 times, evenly and at an ordinary depth, so she writes 18 breaths per minute on the flow sheet and moves on to the blood pressure cuff. She never told him she was counting his breathing, and he never knew — the count reflected how he truly breathes at rest.
Key takeaway
Respirations — the breaths a person takes per minute — are the quiet vital sign: count them without the patient noticing, and read them as rate, depth, and pattern, because a change in breathing is often the first clue that something else is going on.

Common mistakes
Announcing the count: 'I'm going to count your breathing now.'
Breathing is partly voluntary, so telling a patient you are counting invites an altered pattern — faster, slower, or deeper than usual. Count quietly while appearing to finish the pulse check, then record the true number.
Counting the rise and the fall as two breaths.
One breath is one complete cycle: the rise (inhalation) plus the fall (exhalation) together count as a single breath. Counting each movement separately doubles the number.
Recording only the number and skipping depth and pattern.
Respirations are described by rate, depth, and pattern together. A normal count can hide shallow or irregular breathing, so all three belong in the assessment.
Treating any count outside the range as dangerous on its own.
The range is a reference for resting adults, not a rule. Age, activity, and the patient's own baseline all matter — an unusual count is a cue to look closer and report, not a diagnosis.
Counting respirations while the patient is talking or moving.
Speech and motion change the count. The number is most meaningful when the patient is at rest, breathing quietly — the state the reference range describes.
Easily confused
Rate vs. Depth
Rate is how many breaths a person takes per minute; depth is how full each breath is. The two can move independently — a fast rate can come with shallow breaths, which is why both are assessed.
Respirations vs. Pulse
Both are counts per minute, but the pulse is automatic while respirations are partly voluntary — people can change their breathing when they think about it. That is why respirations are counted without the patient's awareness.
Tachypnea vs. Bradypnea
Tachypnea is breathing faster than the adult resting reference (above about 20 breaths per minute); bradypnea is breathing slower (below about 12). Both are directional terms, not diagnoses.
