Understanding the Equation for Mean Arterial Pressure: Essential Facts Explained
In the bustling city of Houston, Texas, Ighodalo Oribhabor, a Registered Nurse and content creator, has been making waves in the medical community and beyond. With over 80,000 followers across Instagram, TikTok, and Facebook, Oribhabor is using his platform to share his passion for nursing and storytelling.
Oribhabor's journey in the nursing field began with an Associate Degree in Nursing from the University of Houston - Downtown, followed by a Bachelor of Science in Nursing degree. Today, he has over 2 years of experience in the nursing field and works in a step-down ICU trauma unit.
One of the key aspects of Oribhabor's content is demystifying medical terms and procedures for his audience. In this article, we'll focus on Mean Arterial Pressure (MAP), a crucial measurement in cardiovascular health.
MAP, the average blood pressure, can be found using the equation MAP = (2(DBP) + SBP)/3, where DBP is diastolic pressure and SBP is systolic pressure. The diastolic pressure is the pressure during the 'rest' period between heartbeats, while the systolic pressure is the pressure of the blood in the arteries during a heartbeat.
A normal MAP value falls between 70-110 mm Hg. However, certain medical conditions and medications can alter what is considered a 'normal' or 'healthy' MAP score. If you have a resting MAP outside the 'normal' range or abnormal values for systolic or diastolic blood pressures, it's crucial to consult a doctor.
To perform a manual blood pressure test, you'll need a blood pressure cuff and a stethoscope. When inflating the cuff, inflate it to a pressure that's about 30 mm Hg higher than you expect your systolic pressure to be. Once deflated, the point at which the sound of the blood flow reappears indicates your systolic pressure, and the pressure at which the sound disappears and reappears again indicates your diastolic pressure.
For estimation purposes, use the formula MAP approx = CO × SVR, where CO is cardiac output and SVR is systemic vascular resistance. However, it's important to note that this formula requires specific medical knowledge and equipment to calculate accurately.
