Pulmonary pulse pressure is normally much lower than systemic blood pressure due to the higher compliance of the pulmonary system compared to the arterial circulation. [6] It is measured by right heart catheterization or may be estimated by transthoracic echocardiography. Normal pulmonary artery pressure is 8 mmHg–20 mmHg at rest. [7]
With a maximal stress test the level of exercise is increased until the person's heart rate will not increase any higher, despite increased exercise. A fairly accurate estimate of the target heart rate, based on extensive clinical research, can be estimated by the formula 220 beats per minute minus patient's age.
This is an incomplete list, which may never be able to satisfy certain standards for completion. There are many conditions of or affecting the human circulatory system — the biological system that includes the pumping and channeling of blood to and from the body and lungs with heart, blood and blood vessels.

A normal systolic blood pressure will be less than 120 mm Hg, and a normal diastolic blood pressure will be less than 80 mm Hg. [3] A blood pressure that is more than 15 mm Hg different between the right and left arm may indicate a problem with the patient's blood vessels. [1] A normal heart rate is between 60 and 100 beats per minute.
The pulse may vary due to exercise, fitness level, disease, emotions, and medications. [11] The pulse also varies with age. A newborn can have a heart rate of 100–160 bpm, an infant (0–5 months old) a heart rate of 90–150 bpm, and a toddler (6–12 months old) a heart rate of 80–140 bpm. [12]
Blood pressure is expressed by two measurements, the systolic and diastolic pressures, which are the maximum and minimum pressures, respectively. [63] Normal blood pressure when at rest is within the range of 100–140 millimeters mercury (mmHg) systolic and 60–90 mmHg diastolic. [68]
Pulmonary heart disease, also known as cor pulmonale, is the enlargement and failure of the right ventricle of the heart as a response to increased vascular resistance (such as from pulmonic stenosis) or high blood pressure in the lungs. [2]
Hypertension – elevated blood pressure above "normal." Long term high blood pressure is a major risk factor for coronary artery disease, stroke, heart failure, peripheral vascular disease, vision loss, and chronic kidney disease. [2] [3] Lowering blood pressure is key for preventing these diseases. Types of hypertension
