In a strict sense, it can be said that a puff is the amount of air that is expelled through the mouth, directly and quickly. Similarly, it can be the perceptible air current in the environment. In colloquial terms, "puff" is an expression that takes on a tinge of speed, especially when it is related to waiting and distraction. In addition to these meanings, there is that of the heart murmur, perhaps the best known or most widespread of the word; This refers to the grating or harsh sound that occurs when the heart begins to beat, as a result of turbulent uneven blood flow through the heart valves.
Murmurs, generally speaking, are caused by increased flow in a normal heart valve. Now, this anomaly can be produced both by stenosis, insufficiency, double injury, as well as by some irregularities in the internal or external zone of the cardiovascular system. To properly classify a murmur, a series of characteristics about the sound and the beat must be taken into account, such as: time, referring to whether it is systolic or diastolic; the shape or intensity, the location, that is, the area in which the murmur experiences its greatest intensity, these points being the intercostal spaces; irradiation, or the point to which the sound radiates; the intensity of the sound, which can range from 0 to 6, expressed in Roman numerals; the tone, being able to be high or low; lastly, the sound quality, that is, the characteristics of the sound melody. In general, they can be located in a range that goes from 0 to 6.
