Basic concepts of patient monitoring
– Abbreviation/another name: physiological monitoring system, vital signs monitoring, bedside monitor
Monitor: A tool to deal with and display an event
In what cases is it used?
The patient monitor collects information about the patient’s vital signs, displays them on the screen, and gives the necessary warnings to the medical team in case of adverse patient conditions.
Physiology
The patient monitor records many parameters of the patient using different methods. These parameters include ECG, IBP, NIBP, body temperature, SpO2, cardiac output, heart rate, breathing rate, respiratory gases, EEG and blood gases.
,
How does it work?
A monitor collects different parameters related to the patient in different ways. After amplification and processing, the inputs are displayed as a waveform or numerical values, depending on the type of information that can be displayed. The alarm range of the device is set on specific values related to each parameter to alert the medical team in case of inappropriate conditions of the patient. ,

Units of measurement
Heart rate: beats per minute (BPM)
Blood pressure, mmHg
Temperature, degrees Celsius (C?).
SpO2: %
Cardiac output: liters per minute (L/min).
Breathing rate: beats per minute (BPM).
Respiratory gases: % or part of the pressure in millimeters of mercury (mmHg).
– Typical and common values
For adults:
Heart rate: BPM 50-90
Blood pressure: (100) 80/120 mmHg
Temperature: C? 37
SpO2: 95-100%
Cardiac output: 6 L/min
Breathing rate: 12 BPM
Gas saturation level: nitrogen 79%, oxygen 17%, carbon dioxide 4%
For babies:
Heart rate: 120-180 BPM
Blood pressure: ?!
Temperature: C? 37
SpO2: 98-95%
Cardiac output: mL/min?!
Breathing rate: BPM 40-80
Gas saturation level: nitrogen 79%, oxygen 17%, carbon dioxide 4%

Purchase considerations
One of the important points in choosing a monitor for treatment centers and hospitals is to pay attention to special care departments and other high-sensitivity departments. An operating room monitor should display the main parameters such as ECG, IBP, NIBP, SpO2, body temperature, pulmonary output and ETCO2, in other words, these parameters are the minimum specifications required to use the monitor in These are the parts. Another important point is the use of the arrhythmia detection system, which has the ability to display and alarm to inform medical personnel in critical situations https://t.me/joinchat/LGFNuFbsiWDOnIal9Q65LA
