Тонометр вимірює артеріальний тиск.

• тонометр = blood pressure monitor / tonometer
• вимірює = measures
• артеріальний = arterial
• тиск = pressure

So the whole sentence literally matches The blood pressure monitor measures arterial pressure, which in natural English is usually just A blood pressure monitor measures blood pressure.

вимірює is the 3rd person singular present tense form of вимірювати / виміряти meaning to measure.

Here it means it measures, because the subject is тонометр.

So:

• я вимірюю = I measure
• ти вимірюєш = you measure
• він / вона / воно вимірює = he / she / it measures

Since тонометр is a singular noun, вимірює is the correct form.

Ukrainian does not have articles like a or the.

So тонометр can mean:

• a blood pressure monitor
• the blood pressure monitor

The exact meaning depends on context. In a general statement like this one, English often uses a:

• A blood pressure monitor measures blood pressure.

Because артеріальний is an adjective describing тиск.

In Ukrainian, adjectives must agree with the noun in:

• gender
• number
• case

Here:

• тиск is masculine singular
• it is in the accusative case
• for an inanimate masculine singular noun, the accusative looks like the nominative

So the adjective also takes the matching masculine singular form:

• артеріальний тиск

Yes. тиск is the direct object of the verb вимірює, so it is in the accusative case.

However, with inanimate masculine nouns, the accusative singular is usually the same as the nominative singular.

So:

• nominative: тиск
• accusative: тиск

That is why it looks unchanged.

Yes, тонометр is a masculine noun.

A common clue is that many masculine nouns in Ukrainian end in a consonant, and тонометр ends in -р.

That matters for agreement:

• тонометр вимірює = the monitor measures
• if you added an adjective, it would also be masculine:
  • новий тонометр = a new blood pressure monitor

The normal, neutral word order here is:

• Тонометр — subject
• вимірює — verb
• артеріальний тиск — object

So: Тонометр вимірює артеріальний тиск.

But Ukrainian word order is more flexible than English because case endings help show grammatical roles. Other orders are possible for emphasis, for example:

• Артеріальний тиск вимірює тонометр.

This can sound more contrastive or emphatic, something like It is arterial pressure that a blood pressure monitor measures.

For learners, the original order is the safest and most natural.

A rough pronunciation is:

• ви-МІ-рю-є

The stress is on мі:

• вимі́рює

A rough English-style approximation would be something like:

• vy-MEE-ryu-ye

A few helpful notes:

• ви sounds like vy
• мі is like mee
• рю has a softened r sound
• є here sounds like ye

Both are possible, but they are not equally specific.

• тиск just means pressure
• артеріальний тиск specifically means arterial pressure, i.e. blood pressure

In medical or instructional language, Ukrainian often uses the more precise phrase артеріальний тиск.

In everyday speech, people may also say:

• міряти тиск = to measure blood pressure

Even though тиск literally just means pressure, the medical meaning is often understood from context.

Yes, кров’яний тиск is also understandable and means blood pressure.

However, артеріальний тиск is the more formal and medically precise expression. It is very common in healthcare, instructions, and official language.

So:

• артеріальний тиск = more formal / medical
• кров’яний тиск = more everyday, still correct

Yes. The sentence is a general statement: it describes what a blood pressure monitor does.

Ukrainian often uses the present tense for general truths and habitual actions, just like English:

• Тонометр вимірює артеріальний тиск.
• A blood pressure monitor measures blood pressure.

It does not necessarily mean that a monitor is measuring something right now. It can simply describe its function.

Sometimes Ukrainian can omit a subject when it is already clear from context, but in this sentence the noun тонометр is important because it tells you what does the measuring.

So the full sentence:

• Тонометр вимірює артеріальний тиск.

is the natural choice.

If you only said:

• Вимірює артеріальний тиск

that would usually sound incomplete on its own unless the subject had already been mentioned earlier.
