Pulse is an indicator of a person’s physical condition. To assess the degree of injury and its severity, it is very important to be able to determine and correctly understand some parameters and indicators of the cardiovascular system.
Pulse and blood pressure as an indicator of a person’s physical condition, the value of blood pressure and pulse.
The simplest of them, for the assessment of which special equipment or training is not required, are measurements of blood pressure and heart rate of the pulse value. Normally, the pulse rate in an adult is 60-80 beats per minute. With physical activity, as well as with emotional stress, the pulse can reach 100 beats per minute or more. If the heart rate exceeds 100 beats per minute, then this condition is called tachycardia, and if the number of beats per minute is 50 or less bradycardia.
), the filling of the pulse sometimes drops to the complete disappearance of sensations of changes in the volume of the artery. Such a pulse is called empty, which indicates the severity of the condition of the victim. Lack of pulse and respiratory arrest mean a violation of the cardiac and respiratory activities of the body. As a result, organs and tissues are no longer supplied with oxygen.
The brain is most sensitive to lack of oxygen. 3-5 minutes after stopping blood circulation, necrosis of brain cells begins, and then alternately of other organs. In the absence of a pulse and breathing, resuscitation should immediately begin (massage: heart and artificial respiration). Resuscitation, i.e., revitalization, is done so that the body itself can resume cardiac and respiratory activity.
The value of blood pressure, as well as the pulse, is very important for determining and evaluating the functioning of the cardiovascular system. For this purpose, as a rule, a special device used is a tonometer and a stethophonendoscope. But in an emergency after an accident or during a natural disaster, it may not be the first-aid kit, as well as the first-aid kit itself.
Blood pressure provides a lot of different information about a person’s condition. So, with high blood pressure, for example 180/90 or even 200/100, we can assume a hypertensive crisis, and with lower rates, for example 70/40, with a pulse exceeding 120 beats per minute, we can talk about heavy blood loss or significant loss of water by the body . Indicators such as profuse vomiting, diarrhea, and excessive sweating may also contribute to the latter determination..
