DAN Europe: Assessing Basic Vital Signs

Assessing vital signs (‘vitals’) is a key component of good first aid. It consists of taking a series of simple measurements that provide data about a body's functioning. These measurements can help reveal how sick or hurt a patient is and, when taken over time, whether he is getting better or worse. While the full meaning of these measurements might elude the lay provider, a carefully documented series of vitals can be very helpful to the healthcare professionals who will eventually take over the care of an injured person.

Vital signs can be helpful even to first-aid providers with limited medical training. Sets of vitals that are outside normal ranges typically indicate the need for some treatment or possible evacuation to a higher level of care. As an example: Anxiety, elevated heart rate, elevated respiratory rate and pale, cool, clammy skin may indicate shock, a potentially life-threatening medical condition. Shock is relatively easy to address, but it can go unnoticed if vitals aren't monitored. Vital signs that move increasingly further from their normal range over time may indicate an even more urgent need for evacuation.

Time

To organise and keep track of your measurements, it is very important to document the time of day along with each set of vital signs. This allows you (or a subsequent caregiver) to make comparisons between sets of vitals and observe trends in the patient's condition. The frequency with which vitals are taken depends on the patient's condition. Seriously injured or ill patients should have their vital signs reassessed every few minutes, while hourly checks are reasonable for those who are stable.

Level of responsiveness

An injured person's mental status, or level of responsiveness, is probably the most-important vital sign. Since the brain has top priority in the body's distribution of resources, a decline in its status is especially important to recognise. To assess a patient's level of responsiveness, begin talking to the person. If the person is able to respond to you, ask him the following questions:

  • What is your name?
  • Where are we?
  • What time is it (approximately)?
  • What happened?

Answers to these four questions allow you to gauge a patient's orientation to person, place, time and event. If the patient can answer all four appropriately, he would be considered ‘Alert and Oriented to Person, Place, Time and Event’ or, more commonly, A+Ox4 (read ‘A and O by four’). In addition to quantifying the patient's level of responsiveness, it's also helpful to write down a qualifying term. Helpful qualifiers include ‘irritable’, ‘anxious’ or ‘combative’. Words like these help round out your description of the patient's mental status.

In the event that an injured person is awake and can respond to you but does not know the answers to any of these questions, that person can be considered alert but disoriented.

A common scale used to describe a person's mental status is the AVPU scale. AVPU is an acronym that stands for ‘alert, verbal, painful and unresponsive’. The paragraph above describes patients who have an A rating on this scale, but sometimes ill or injured people are not alert. If the person does not respond when you attempt to engage him in conversation, talk louder. In a loud voice, ask if he is okay.

If he responds to this elevation in volume, he can be considered responsive to verbal stimulation or V on the AVPU scale. The person doesn't have to respond verbally to be considered V; he may simply grimace or open his eyes, but any response to sound means he is a V. If the person does not respond to your verbal stimulus, you should assess his responsiveness to pain. It is important not to cause harm, but simply elicit a response. A good way to do this is to pinch the patient's tricep, just above the elbow. If this causes the patient to respond, by moving or groaning, for example, the patient is a P on the AVPU scale. Finally, a patient who does not respond to verbal or painful stimulation is considered unresponsive, or U, on the AVPU scale.

Pulse

A strong heartbeat is required to ensure an adequate supply of oxygenated blood to the body's tissues. To assess the pulse in an unconscious person (V, P or U on the AVPU scale), you can use the carotid artery in the neck. Place two of your fingers gently on the patient's trachea and slide them laterally. Do not reach across the trachea (use the near side), and do not try to assess on both sides of the neck at once.

You should feel the pulse in the carotid artery right next to the trachea. In a conscious patient (A on the AVPU scale), it is best to find the radial pulse on the wrist; this is less invasive.

To find the radial pulse, place two of your fingers where the base of the patient's thumb meets his wrist. The pulse will most likely be between that spot and the most-prominent tendons of the wrist.

If you are having difficulty finding the heart rate, you may be pressing too hard or not pressing hard enough. Once you locate the pulse, count the number of beats in 15 seconds. Multiply this number by four, and you'll have the patient's heart rate in beats per minute.

In addition to the rate, it's important to document the rhythm and quality of the pulse. The rhythm will be either regular or irregular, and the quality will usually be described as strong or weak. Most healthy adults have a resting heart rate of between 60 and 100 beats per minute, regular and strong. People experience a natural elevation in their heart rate when performing exercise or in stressful situations. The heart beats faster to ensure sufficient oxygenation of tissues, allowing the body to respond quickly in emergencies. A person's pulse may be elevated shortly after an emergency, but this should stabilise in people who are not seriously injured.

Note: ERC guidelines state that lay rescuers do not need to check the pulse but look for normal breathing when assessing an unconscious person. When there is no normal breathing, lay rescuers should start CPR and use an AED.

Respiration

Since the body can survive for only a few minutes without oxygen, it's important to check the function of the respiratory system. If a person knows you are trying to count his respirations, he will probably change his rate of breathing and skew your measurement. To get around this, transition smoothly to counting respirations as soon as you are finished checking the pulse. Once you have counted the heart rate, shift your focus to the breathing. Leave your fingers on his wrist, but watch for his chest to rise. If you're unable to detect respirations by watching the chest, it might be helpful to watch the abdomen or the shoulders instead. Folds of the patient's clothing might also aid your observation of respirations.

Since respirations are less frequent than heartbeats, count respirations for 30 seconds, then double the number to achieve an accurate result. As with pulse, measuring the rhythm and quality of respirations is important. Rhythm will be either regular or irregular. Words like ‘unlabored’, ‘gasping’, ‘wheezing’ or ‘labored’ are used to describe the quality of respirations. An adult at rest typically breathes between 12 and 18 times per minute, regular and unlabored.

Skin

Skin is the body's largest organ, and it can be an excellent window into the body's functioning. If the skin is pale, cool and clammy, this is a sign that the body's resources (i.e, blood) are being diverted to more vital organs. When assessing the skin, you should take note of three different characteristics: colour, temperature and moisture.

Skin colour, of course, varies widely among individuals, but there are non-pigmented areas of the body where all humans are pink. The most accessible of these places is the inside of the bottom lip. Take a look and note whether the colour is indeed pink or some other colour. It might be pale if the person is cold, blue if he is hypoxic, red if he is hot or even yellow if he is suffering from some illness. Temperature and moisture of the skin are best assessed on the abdomen. These are generally more consistent there than on the hands or the face. The abdomen should be warm and dry, so if it's cool, cold, hot or moist, that is especially important to document.

Level of responsiveness, pulse, respirations and skin condition are by no means the only vital signs, but they are important and relatively easy to assess. The only equipment necessary to measure these is a watch, a pen and paper. Other vital signs include blood pressure, lung sounds, pupils and body temperature. Though training, experience or equipment may limit your ability to care for an injured buddy in a remote environment, assessing basic vitals is something just about anybody can do to help.
