The carotid and aortic bodies and central chemoreceptors respond to the partial pressure of oxygen (PO 2 ), partial pressure of carbon dioxide (PCO 2 ) and pH of the blood and cerebrospinal fluid. (aafp.org)

It may be supported by a HRCT scan or lung biopsy which show usual interstitial pneumonia (UIP). (wikipedia.org)
Considering that any type of pneumonia causes air volume changes in the lungs, accumulating evidence has shown that LUS effectively measures the presence of VAP as well as dynamic changes in VAP. (medscape.com)

We also observed a positive correlation between baseline serum IGF-1 level and DLCO/VA and between years of disease and DLCO/VA, showing the association of increased lung volume and increase of the exchange surface. (scirp.org)

Pulmonary function tests (PFT) are several tests done to show us how well your lungs are working. (wdhospital.org)
T his tests measures how quickly oxygen and carbon dioxide travel from your lungs into your blood. (wdhospital.org)
These tests measure the blood's oxygen and carbon dioxide levels, which can help evaluate how well the lungs work. (marham.pk)
These tests evaluate breathing patterns and oxygen levels during sleep, which can help diagnose sleep apnea and other sleep-related respiratory problems. (marham.pk)
These are tests which determine how well your lungs are functioning and most involve blowing into a tube with your nose plugged. (cornwallhospital.ca)
A battery of studies or procedures that may be carried out using standardized equipment to determine lung function is referred to as pulmonary function tests (PFTs) or lung function tests. (postfores.com)
Further tests, such as static lung volumes and diffusion measurements (called complete series of pulmonary function tests) may be necessary and can only be performed in highly equipped offices. (vittorakis.com)
