Hospital monitors are electronic devices that track a patient's vital signs, such as heart rate, blood pressure, and body temperature. They are a common sight in hospitals, with their multi-coloured numbers and wavy lines, beeping noises, and flashing colours. They can be intimidating and overwhelming, especially for those unfamiliar with their complex displays. Small sensors attached to the patient's body transmit information to the monitor, which is then displayed on the screen, providing clinicians with a general overview of the patient's real-time vitals. This information can be vital in emergency situations, guiding acute resuscitations, and managing arrhythmias.
| Characteristics | Values |
|---|---|
| Heart Rate | Typically in green numbers, identified by "HR" or "PR" (pulse rate) and presented in beats per minute (BPM) |
| Blood Pressure | Presented under "SYST" or "SYS" for systolic and "DIAS" or "DIA" for diastolic |
| Oxygen Saturation | Located under "SpO2", measures the amount of oxygen in the patient's blood |
| Respiration Rate | Reported under "RR" in breaths per minute |
| Invasive Blood Pressure | Reported under "IBP" in mmHg |
| Non-Invasive Blood Pressure | Reported under "NIBP" in mmHg |
| Carbon Dioxide | Reported under "CO2" in mmHg |
| ECG Strip | Typically represents one lead, usually lead II |
| Respiratory Waveform | Useful for monitoring respiratory issues such as apnea or dyspnea |
| SpO2 Waveform | Helps determine issues with circulation or peripheral perfusion |
| Warning | If vital signs fall outside healthy levels, the monitor will beep and flash |

What You'll Learn
Heart rate
The heart rate reading on a patient monitor is often accompanied by an ECG (electrocardiogram) strip, which is usually the top wavy line on the monitor. This strip records the electrical activity of the heart and can be useful for guiding acute resuscitations or managing arrhythmias. It provides information on the heart's electrical activity and level of function. While it is not intended for in-depth ECG analysis, the strip can help detect abnormal heart rhythms by comparing the current reading to a previous baseline.
In addition to ECG strips, heart rate monitors may use other technologies to track heart rate. Wearable devices, for instance, often rely on electrical or optical detection methods. Electrical detection involves measuring the electrical current generated by the heart with each heartbeat. Optical detection, on the other hand, uses infrared light or LED lights to detect the expansion of blood vessels or arteries as the heart pumps blood through them.

Blood pressure
Invasive blood pressure (IBP), also known as Arterial Blood Pressure (ART), is reported in mmHg and can be visualised using the IBP Waveform. This is achieved by inserting a thin, flexible tube called an arterial line or catheter into an artery, which is connected to flushed and airless tubing. The transducer reflects changes in intra-arterial pressure and is positioned at heart level. Arterial pressure monitoring is a form of invasive blood pressure measurement that provides continuous, real-time data, allowing for prompt detection of hemodynamic changes. It is particularly useful for critically ill patients, those with unstable cardiopulmonary status, and during perioperative care when precise blood pressure control is essential.
Non-invasive blood pressure (NIBP) is also reported in mmHg and can be measured using an automatic, upper arm cuff-style monitor. The American Heart Association (AHA) recommends home monitoring for individuals diagnosed with high blood pressure or with risk factors for high blood pressure. Wrist and finger monitors are not recommended due to less reliable readings. To ensure accuracy, individuals should refrain from smoking, drinking caffeinated beverages, or exercising within 30 minutes before taking their blood pressure.

Oxygen saturation
The SpO2 waveform allows clinicians to identify any issues with circulation or peripheral perfusion. Each peak of the SpO2 waveform should correspond with a heartbeat on the ECG waveform at similar intervals since oxygenated blood is pumped out of the heart with each heartbeat. This correlation between the SpO2 and ECG waveforms is essential for assessing the patient's cardiovascular health and oxygenation status.
The ECG readout on the patient monitor provides limited information and is typically used for guiding acute resuscitations or managing arrhythmias. It offers insights into the electrical activity and function of the heart. However, for detailed ECG analysis, a 12-lead ECG is necessary.
In addition to oxygen saturation, patient monitors track other vital signs, including heart rate and blood pressure. Heart rate is usually displayed using green numbers in the right corner of the screen, identified by "HR" or "PR" (pulse rate). Blood pressure is presented under "SYS" or "SYST" for systolic and "DIA" or "DIAS" for diastolic.
These monitors are essential for providing clinicians with a comprehensive overview of a patient's real-time vitals, enabling early detection of any abnormalities and facilitating timely interventions.

Respiratory rate
The respiratory waveform is an important tool for clinicians monitoring respiratory issues such as apnea or dyspnea. The SpO2 waveform, for example, allows clinicians to determine whether there are any issues with circulation or peripheral perfusion. Each peak of the SpO2 waveform should correlate with a heartbeat on the ECG waveform at the same intervals, as oxygenated blood is pumped out of the heart with each heartbeat.
The CO2 waveform is another important tool, helping clinicians visualize how much carbon dioxide a patient is exhaling. Normal CO2 waveforms are generally rectangular in shape.
Vital sign monitors have been a common sight in hospitals for over 40 years. They are an important tool for clinicians to monitor a patient's health and can alert them to any potential issues. Small sensors attached to the patient's body carry information to the monitor, which is then displayed as numerical data and waveforms.
While there are many different models of vital sign monitors, most work in a similar way. The basic models show heart rate, blood pressure, and body temperature. More advanced models can also show how much oxygen the blood is carrying, how fast the patient is breathing, and even how much pressure is on the brain.

ECG readout
An ECG, or electrocardiogram, is a common medical test that records the electrical signals travelling through the heart to check for problems. The test is non-invasive and involves attaching small sensors to the patient's body, which then transmit data to a monitor. The monitor displays the data in the form of a waveform, with the vertical and horizontal axes representing voltage and time, respectively.
The waveform on an ECG readout typically consists of a series of peaks and valleys, which represent the electrical activity of the heart. The most common waveform pattern is called a "PQRST" complex, which corresponds to the different phases of a heartbeat:
- P wave: Represents atrial depolarization, or the contraction of the atria.
- QRS complex: Represents ventricular depolarization, or the contraction of the ventricles.
- T wave: Represents ventricular repolarization, or the relaxation of the ventricles.
The analysis of an ECG readout involves measuring various intervals and segments of the waveform. For example, the PR interval is measured from the beginning of the P wave to the start of the QRS complex, and it represents the time taken for the electrical impulse to travel from the atria to the ventricles. The QT interval is measured from the beginning of the QRS complex to the end of the T wave, and it reflects the duration of ventricular depolarization and repolarization.
In addition to the waveform analysis, the heart rate can be determined from an ECG readout. For patients with a regular heart rhythm, the heart rate can be calculated by counting the number of large squares within one R-R interval (the interval between two consecutive R waves) and referring to a predetermined value. For patients with an irregular heart rhythm, the heart rate can be estimated by counting the number of QRS complexes in a 6-second rhythm strip and multiplying by 10.
While the interpretation of ECG readouts is a complex process that requires medical expertise, understanding the basic principles and components of the readout can provide valuable insights into cardiac function and potential abnormalities.

Frequently asked questions
A hospital monitor is a device that displays a patient's vital signs in real time.
Most hospital monitors show heart rate, blood pressure, and body temperature. More advanced models also show oxygen saturation, respiratory rate, and carbon dioxide output.
The numbers on a hospital monitor typically represent vital signs such as heart rate, blood pressure, and respiratory rate. The lines, or waveforms, visually represent the patient's vital signs over time.
If a patient's vital signs fall outside of the healthy range, the monitor will typically sound an alarm and flash a warning on the screen. This alerts caregivers to check on the patient.
