Mechanical. A classic design of a blood pressure monitor that many are familiar with includes a shoulder-worn cuff (see "Place of measurement"), a pear for cuff inflation, and a mechanical pressure indicator. This method of measurement requires a phonendoscope, which may be included with the blood pressure monitor or purchased separately. While the procedure is relatively simple, it demands a certain level of skill, and the accuracy of such measurements is considered the lowest among all types of blood pressure monitors. On the positive side, mechanical devices are straightforward in design, cost-effective, do not require a power supply, and can be used in any conditions.

Automatic. These blood pressure monitors are the most user-friendly: users simply need to place the cuff on the upper arm or wrist (see "Place of measurement") and press a button. The device autonomously handles cuff compression for measurements and displays the results on the screen. Automatic blood pressure monitors can come with various additional functions (see "Features") and are regarded as the most accurate. However, they necessitate mains or battery power and are more expensive compared to other types.

Semi-automatic. These blood pressure monitors serve as a "transitional option" between mechanical and automatic devices. They employ electronic sensors for measurements similar
...to automatic ones, but the cuff is manually inflated using a pear. This design enables the inclusion of additional functions typically found in automatic blood pressure monitors at a considerably lower cost. However, they do require a power supply (although they are more energy-efficient than automatic ones due to the absence of a compressor), and their measurement accuracy is lower compared to automatic models.Here, it refers to a
battery level indicator on the blood pressure monitor display, showed as an icon similar to those found on mobile phones. While the charge indication is typically approximate, this feature allows users to monitor battery status and prepare for replacements in advance.

Additional cuff. The blood pressure monitor set includes two cuffs, main and auxiliary, which differ from each other only in standard size. Usually, the auxiliary cuff has a longer length. For example, if the length of the main cuff is 22-36 cm, then the auxiliary cuff will be one size larger, that is, 30-42 cm. An additional larger cuff allows you to expand the circle of users of the blood pressure monitor.

Power source. Blood pressure monitors with a power supply option can operate using a 230 V household power supply, eliminating the need for frequent battery replacements. Interestingly, many of these monitors also come equipped with batteries, providing users flexibility in choosing the power source for the measuring device.
—
Cover/case. The blood pressure monitor comes with a dedicated bag for convenient storage and transportation of all its components. Depending on the tonometer's configuration, the case can accommodate the device, primary and auxiliary cuffs, a stethoscope, spare batteries, a power supply, and instructions. Some cases even include an extra compartment for storing medications. Typically, the tonometer bag is soft.
— Batteries. The blood pressure monitor operates on replaceable batteries, commonly using AA or AAA batteries. This battery-powered design makes the device self-contained, allowing its use in remo
...te locations or while traveling without access to a household electrical outlet. However, a drawback of battery-powered blood pressure monitors is the requirement for regular battery replacement or recharging.
