Speaking roughly, normal levels of thyroid-stimulating hormone (TSH) are in the range of 0.4 to 4.0 mIU/L. However, each laboratory and test manufacturer identifies its own normal TSH range.
This pressure is typically set slightly higher than atmospheric pressure to prevent atelectasis, decrease inspiratory work of breathing, or improve gas exchange depending on the clinical scenario. This positive end-expiratory pressure (PEEP) is generated by a resistor in the exhalation port of the ventilator (Fig. 2).
(see state postulate)NOTEWhile the vapor pressure is similar to the saturation pressure, thevapor pressure refers to the pressure in a mixture of components(i.e., the total pressure is higher).OUTCOME:Describe the difference between the saturation and vapor pressures.
