The lower boundary of IIP 3 saturation in Fig. 3 is related to the transmitted signal power Psig.
The impairment can be either gain (X k =G k (dB)), IIP 3 (X k =1/IIP3), or noise factor (X k =F k −1).
The population treated (surgical vs. medical ICU, diabetes status) may also affect the performance of the IIP [2, 28, 39, 40].
It has been defined as a distinct IIP entity in the English literature by Frankel et al. [5] and was recently included in the International Multidisciplinary Classification of the Idiopathic Interstitial Pneumonias of the American Thoracic Society/European Respiratory Society in the category of rare IIP [9].
Concerning the aetiology, our data are also in agreement with published cases with one of the patients having a history of recurrent respiratory infections and other familiar history of IIP [12].
When an intermodulated signal by the third order nonlinearity has a power as large as the power of a transmitted sinusoid, the transmission power is defined as IIP 3. Thus, the transmitted signal power Psig should be smaller than IIP3 as follows, P_{text{sig} text{ dBm)}} < text{IIP}_{3 text{ dBm)}}.
Pulmonary fibrosis can result from a variety of causes, including lung injury, environmental particle and toxin inhalation, chemotherapy, systemic autoimmune diseases, or as an idiopathic entity in form of idiopathic interstitial pneumonias (IIP) [1] [4].
In the remaining 35 patients with diagnosis of IIP, 28 patients had only the pneumocystis jiroveci pneumonia (PJP) infection.
One instrument measured interpersonal functioning: the Inventory of Interpersonal Problems (IIP) (64 items) [ 21], a five-point scale ranging from 0 = 'no problem' to 4 = 'severe problems'.
The NJH ILD cohort consists of 131 patients with biopsy-proven IIP (111 IPF/UIP, 12 iNSIP, and 8 uncharacterized fibrosis) that were clinically evaluated by investigators at National Jewish Health.
We measured the serum levels of the autoantibodies to HSP47 in 38 patients with various forms of IIP [16 with idiopathic pulmonary fibrosis (IPF), 15 with idiopathic NSIP, 7 with cryptogenic organizing pneumonia (COP)] and 18 healthy volunteers.
