  • asthma
  • Doctors can also measure changes in a child's lung function over time or during ongoing therapy, or his or her immediate response to medications for asthma. (nyp.org)
  • The report contains company profiling of major companies associated with marketing of major respiratory drugs covering asthma, COPD, cystic fibrosis and PAH. (bio-medicine.org)
  • quotient
  • The alveolar gas equation is used to calculate the PAO 2 on the basis of the relationship between the pressure of oxygen in inspired gas (PiO 2 ), the PaCO 2 , and the respiratory quotient (RQ), as follows: PAO 2 = FiO 2 (Pb - P H 2O) - (PaCO 2 /RQ). (medscape.com)
  • impairment
  • Respiratory impairment in working coal miners. (cdc.gov)
  • The types of physiological respiratory impairment seen in coal miners are described in an attempt to decide which of the impairments are related to coal mining and which to naturally occurring disease. (cdc.gov)
  • The overall conclusion is that both the prevalence of pneumoconiosis and the prevalence of respiratory impairment differ in various geographical regions, probably due to physical or chemical composition of coal dust to which the men are exposed. (cdc.gov)
  • longitudinal
  • Normal-weight subjects typically have equivalent values when tested sitting or standing, but, for longitudinal studies, the same test position should be used each time. (ersjournals.com)
  • 13 The longitudinal analysis of the same cohort has suggested that long term occupational exposure significantly accelerated the decline in respiratory function in male dairy farmers. (bmj.com)
  • Oxygen
  • Oxygen saturation , a test to measure the amount of oxygen being carried by the red blood cells. (nyp.org)
  • PiO 2 is a function of the fractional concentration of inspired oxygen (FiO 2 ), the barometric pressure (Pb), and the partial pressure of water vapor (P H 2O) in humidified air. (medscape.com)
  • However, monitoring of respiratory function is suboptimal and uncontrolled oxygen is sometimes used inappropriately before the terminal phase. (bmj.com)
  • The protocol comprised a medical and occupational questionnaire, spirometric tests at both evaluations, allergological tests at T1, and a non-invasive measure of blood oxygen saturation (Sp o 2 ) at T2. (bmj.com)
  • severity
  • These numbers are used to quickly communicate the severity of respiratory failure and can provide some diagnostic and therapeutic guidance (eg, when to start inhaled nitric oxide). (medscape.com)
  • PFTs
  • Subjects who were admitted to the smoking cessation out-patient clinic, underwent pulmonary function tests (PFTs) and completed at least 3 months of the cessation program following their admittance were included in the study. (rcjournal.com)
  • occupational
  • On August 27, 1987, the National Institute for Occupational Safety and Health (NIOSH) published in the Federal Register (52 FR 32401) a Notice of Proposed Rulemaking (NPRM) for certification of respiratory protective devices. (cdc.gov)
  • assess
  • Impulse oscillometry , a test to assess airflow obstruction in children who are not able to perform a forced breathing test. (nyp.org)
  • measurement
  • OBJECTIVE: The aim of the study was to test the applicability of Ventrak 1550/Capnogard 1265 (V-C) for respiratory dead space (VD) measurement and to determine anatomic (VDana), physiologic (VDphys), and alveolar dead spaces (VDalv) in ventilated neonates. (biomedsearch.com)
  • obstruction
  • Once quality has been assured, the next steps involve a series of comparisons 6 that include comparisons of test results with reference values based on healthy subjects 5 , comparisons with known disease or abnormal physiological patterns ( i.e. obstruction and restriction), and comparisons with self, a rather formal term for evaluating change in an individual patient. (ersjournals.com)
  • Extensive
  • In the first NPRM of August 1987, NIOSH proposed extensive changes in the current performance test requirements for certifying respirators. (cdc.gov)
  • weakness
  • The figure describes how a clinician or physiologist suspects and treats respiratory muscle dysfunction (especially unilateral and bilateral diaphragm weakness), outside the intensive care setting. (ersjournals.com)
  • Motor neuron disease (MND), also known as amyotrophic lateral sclerosis, is characterised by progressive weakness of the limb, axial, bulbar and respiratory muscles. (bmj.com)
  • Evaluate
  • Medication evaluation , testing which is repeated after the child is medicated to evaluate the effectiveness of the medication. (nyp.org)
  • To evaluate the effect of chemotherapy and thoracic radiotherapy on pulmonary function and identify predictors of radiation pneumonitis in locally advanced lung cancer [stages IIIA and IIIB]. (clinicaltrials.gov)
