Which layer of the hair is located directly beneath the cuticle layer and is responsible for the incredible strength and elasticity of human hair? hydrogen; hydrogen The term pH is an abbreviation used for potential _____, and the symbol pH represents the quantity of _____ ions in solution.
Arterial and venous pressures are dependent on the patient's access and the QBS. Ideally, the arterial pressure should be no more than - 250, and the venous no greater than 300. But, as mentioned above, it depends much on the patient's access.
Mean arterial pressure can be approximated by adding one-third of the pulse pressure to the diastolic pressure. For a person with a blood pressure of 120/80, for example, the mean arterial pressure would be approximately 80 + 1/3 (40) = 93 mmHg. Mean arterial pressure = diastolic pressure + 1/3 pulse pressure A rise in total peripheral resistance and cardiac rate increases the diastolic pressure more than it increases the systolic pressure.
