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).
PAOP or PAWP is pressure within the pulmonary arterial system when catheter tip âwedgedâ in the tapering branch of one of the pulmonary arteries. in most patients this estimates LVEDP thus is an indicator of LVEDV (preload of the left ventricle) normally 6-12mmHg (1-5mmHg less than the pulmonary artery diastolic pressure)
