vital parameters are measured variables of important body functions that are determined during the control of vital signs. among the most important general observation criteria are the vital parameters pulse, blood pressure, and respiration as well as body temperature. they indicate changes in the physical and psychological state of the person and allow conclusions to be drawn about certain diseases. instead of respiration, however, we measure the so-called electrodermal activity. never heard of it? just wait for it, we'll explain the reason.
but why vital parameters? well, first of all: those body functions are essential for survival. for comedown, we would like to make use of them and help you to understand irregular states. these affect not only your physical health but also your mental health. therefore, we would like to pick you up where your body suffers in order to enable you to bring body and mind into harmony.
pulse rate, also known as heart rate, is the number of times a person's heart beats per minute. normal heart rate varies from person to person, but a normal range for adults is 60 to 100 beats per minute.
when the heart contracts in systole (phase of contraction of the heart muscle with ejection of blood), it pumps blood into the aorta abrupt and with a lot of pressure. this creates a pulse wave that propels the blood into the peripheral vessels.
what can affect the pulse rate?
- emotions can affect heart rate; for example, getting excited or scared can increase the heart rate.
- exercising - or just partying/dancing
- using a stimulant, such as caffeine or cocaine
blood pressure is the force that moves blood through our circulatory system.
it is an important force because oxygen and nutrients would not be pushed around our circulatory system to nourish tissues and organs without blood pressure.
blood pressure is also vital because it delivers white blood cells and antibodies for immunity, and hormones such as insulin.
just as important as providing oxygen and nutrients, the fresh blood that gets delivered is able to pick up the toxic waste products of metabolism, including the carbon dioxide we exhale with every breath, and the toxins we clear through our liver and kidneys. blood itself carries a number of other properties, including its temperature.
what can affect blood pressure?
some drugs, such as cocaine, ecstasy and amphetamines may cause a dramatic increase in your blood pressure and raise your risk of having a stroke or a heart attack.
body temperature is essential for vital metabolic processes in your body to run smoothly. a low temperature can often be just as dangerous as elevated body temperature.
the normal human body temperature range is typically stated as 36.5-37.5 °C (97.7-99.5 °F).
what can affect body temperature?
drugs may cause increased body temperature in five ways: altered thermoregulatory mechanisms, drug administration-related fever, fever from the pharmacologic action of the drug, idiosyncratic reactions, and hypersensitivity reactions.
electrodermal activity (EDA) is the property of the human body that causes continuous variation in the electrical characteristics of the skin.
the traditional theory of EDA holds that skin resistance varies with the state of sweat glands in the skin. sweating is controlled by the sympathetic nervous system, and skin conductance is an indication of psychological or physiological arousal. if the sympathetic branch of the autonomic nervous system is highly aroused, then sweat gland activity also increases, which in turn increases skin conductance. In this way, skin conductance can be a measure of emotional and sympathetic responses.
what can affect electrodermal activity?
external factors such as temperature and humidity affect EDA measurements, which can lead to inconsistent results. internal factors such as medications and hydration can also change EDA measurements, demonstrating inconsistency with the same stimulus level. EDA is a sensitive psychophysiological index of changes in autonomic sympathetic arousal that are integrated with emotional and cognitive states. many biofeedback therapy devices utilize EDA as an indicator of the user's stress response with the goal of helping the user to control anxiety.
