The CNS is educated at an advanced level to care for patients in one of the six described populations and across the continuum of care. The role of the CNS encompasses the patient, the nurse and nursing practice, as well as the healthcare organization and system.
Relative humidity can be expressed as the ratio of the vapor partial pressure of the air-to the saturation vapor partial pressure of the air at the actual dry bulb temperature. Relative humidity by partial pressure.Ï = pw / pws 100% (1).where.elative humidity can also be expressed as the ratio at actual mass of water vapor in a given air volume-to the mass of water vapor required to saturate at this volume. Relative humidity can be expressed as: Ï = mw / mws 100% (2c).
Relative humidity is reported as a percentage of the total amount of moisture that could be held in the air. For instance, if the air is only half saturated with water vapor, the relative humidity will be reported at 50%. If the air holds all the water vapor it can hold, it is 100% saturated. Relative Humidity Technology. A capacitance-type sensor is one way to measure relative humidity. Changes in relative humidity cause the shape of the sensor to change.
