Hospital monitors are crucial medical devices that record a patient's vital signs and health parameters. They can be intimidating to interpret, with their multicoloured numbers and wavy lines, but understanding the basics can help you stay informed about a patient's health. The monitor displays vital signs such as heart rate, blood pressure, oxygen levels, and respiratory rate, using numbers, waveforms, and colours to indicate the patient's condition. The numbers on the right side of the monitor typically indicate pulse rate, body temperature, and blood pressure, while the waveforms and colours provide additional information about the patient's heart rate and breathing patterns. Knowing how to interpret these signs can aid in quick decision-making and better patient care.

Heart rate
Hospital monitors are essential for continuous care, especially for critically ill patients or those undergoing surgery. They display a patient's vital signs, such as heart rate, blood pressure, and oxygen levels, using numbers and graphs.
The heart rate is measured using sensors that detect the electrical signals produced by the heart. These sensors are often placed on the patient's chest using sticky patches called electrodes. When the heart beats, it generates electrical impulses that travel through the body and are picked up by the electrodes, which then send the signals to the monitor.
An electrocardiogram (ECG) records the electrical activity of the heart and is usually the top wavy line on the hospital monitor. Each spike or peak corresponds to a heartbeat. If the patient has a regular heartbeat, these spikes will occur at regular intervals. The ECG waveform can be used to monitor heart rhythms and detect any irregularities.
The SpO2 waveform, which is usually blue but sometimes red, is located under the ECG waveform. It helps monitor the patient's blood flow by showing how well the heart is pumping blood, especially to the extremities. As long as each crest on the SpO2 waveform matches up with a spike on the ECG, it indicates that oxygenated blood is circulating efficiently with each heartbeat.

Blood pressure
According to the Mayo Clinic, a healthy systolic pressure should be between 90 and 120, while a healthy diastolic pressure should be between 60 and 80. However, it is important to note that these numbers may vary depending on individual factors, and only a doctor or medical professional can confirm a diagnosis of high blood pressure.
The American Heart Association (AHA) recommends home monitoring for individuals with high blood pressure to help their healthcare provider evaluate the effectiveness of treatments. Home monitoring can also be used to confirm a diagnosis of high blood pressure. However, it is important to note that home monitoring does not replace regular doctor visits, and individuals should not stop taking prescribed blood pressure medication without consulting their healthcare provider, even if their home readings are in the normal range.
When choosing a blood pressure monitor, it is essential to select one that has been validated and has the correct cuff size for your upper arm. The AHA recommends an automatic, cuff-style, upper arm (bicep) monitor, as wrist and finger monitors are less reliable.

Oxygen levels
Oxygen saturation levels are typically monitored using a pulse oximeter, a small device that clips onto a patient's finger or toe. The pulse oximeter emits beams of light that pass through the fingernail, skin, tissue, and blood, measuring the amount of oxygen in the blood. This is known as the SpO2 level and is displayed as a percentage on the hospital monitor, often accompanied by a pulse oximeter icon. Normal oxygen saturation levels for a healthy person at sea level are between 95% and 100%, with levels below 92% indicating potential hypoxemia.
It's important to note that the accuracy of pulse oximeters can be influenced by various factors, including skin pigmentation. Studies have found that pulse oximeter readings may be artificially higher in non-White patients, leading to a higher risk of undetected hypoxemia. Therefore, it is recommended to monitor other vital signs and seek medical advice if there are concerns about oxygen levels or respiratory distress.
Additionally, pulse oximeters are widely used in hospitals and can be helpful for continuous monitoring, especially for patients with lung and heart disorders who are at risk of low oxygen levels. They provide near-immediate readings and are less invasive than traditional blood oxygen measurement methods.
When reading a hospital monitor, oxygen saturation levels are typically represented by a specific colour, such as blue or red, and displayed as waveforms or graphs. These visual representations help healthcare providers quickly assess a patient's condition and identify any critical values that require immediate attention.

Body temperature
A patient's body temperature is one of the vital signs that can be measured in a medical setting, at home, or elsewhere. Temperature monitoring is a fundamental nursing skill that can provide healthcare providers with valuable insights into a patient's health status.
When reading a hospital monitor, the body temperature is typically the second number you will see, located under the pulse rate. It is usually displayed in degrees Fahrenheit or Celsius. For example, a reading of 98.6°F indicates a normal body temperature. If you are unsure about how to interpret the numbers on the monitor, don't hesitate to ask a doctor or nurse on duty.
It is important to remember that a single reading outside the normal range is usually not a cause for concern. Healthcare professionals will consider multiple readings over time and take the patient's overall context into account when making a diagnosis or starting treatment. Additionally, temperature readings can be affected by various factors, such as hormonal changes, exposure to heat or cold, exercise, and infection. Therefore, it is essential to consult with a healthcare professional if you have any concerns about your temperature readings or experience symptoms such as chills, sweating, or persistent fever.

Respiratory rate
On a hospital monitor, the respiratory rate is usually displayed as "RR" or "RESP". The normal respiratory rate for a resting adult is between 12 and 18 breaths per minute. A respiration rate under 12 or over 25 breaths per minute while resting may indicate an underlying health condition. A patient's respiration rate may increase if they have a fever, and this is usually not a cause for concern. However, it is important to ensure that the patient is not experiencing any difficulty breathing.
The respiratory waveform, usually at the bottom of the screen, can be used to identify apnea (when a patient suddenly stops breathing) or dyspnea (when a patient has difficulty breathing). This waveform is not always present on patient monitors and is more likely to be there if the patient has respiratory issues.
It is recommended to always manually measure respiratory rate as machine measurements can be unreliable.

Frequently asked questions
Heart rate is usually displayed as a number in beats per minute (BPM) and may also be shown on a waveform graph. This number is typically in the top right-hand corner of the monitor screen. A normal resting heart rate is between 60 and 100 BPM.
Respiratory rate is the number of breaths taken per minute. It is usually reported in breaths per minute, with normal values between 12 and 20. This number may be labelled as "Resp Rate" or "RR".
Blood pressure readings consist of two numbers, such as 120/80 mmHg. The first number (systolic) measures the pressure when the heart beats, and the second number (diastolic) measures the pressure when the heart rests between beats. Normal blood pressure is generally around 120/80 mmHg.
Body temperature is typically the second number displayed on the monitor, right below the pulse rate. The normal range for adults is 97.8 to 99 °F (36.6 to 37.2 °C). A body temperature over 99 °F (37 °C) is considered a fever, while anything below 95 °F (35 °C) is considered hypothermia.
