Early exercise pulmonary diffusing capacity of carbon monoxide after anatomical lung resection: a word of caution for fast-track programmes.

Summary of "Early exercise pulmonary diffusing capacity of carbon monoxide after anatomical lung resection: a word of caution for fast-track programmes."

In healthy individuals, increasing pulmonary blood flow during exercise also increases the % of the diffusing capacity of the lungs for carbon monoxide (DLCO%), but its evolution after lung resection is unknown. In this study, our goal was to measure changes in exercise DLCO% during the first 3 days after anatomical lung resection.

Acute effects of hypertonic saline inhalation on nitric oxide pulmonary diffusing capacity in healthy adults.

We investigated acute effects of inhalation of hypertonic saline solution (HSS) and oxygen (O, control exposure) on pulmonary diffusing capacity for nitric oxide (DLNO) and carbon monoxide (DLCO). In ...

Genome-Wide Association Analysis of Single Breath Diffusing Capacity of Carbon Monoxide (DLCO).

Diffusing capacity of carbon monoxide (DLCO) is a widely used pulmonary function test in clinical practice and a particularly useful measure in assessing patients with COPD. We hypothesized that eluci...

Diffusing capacity for carbon monoxide (DLco) reduction is the first detectable pulmonary functional test (PFT) change in systemic sclerosis (SSc)-related pulmonary complications. reduction in patient...

Fitting of single-exhalation profiles using a pulmonary gas exchange model - application to carbon monoxide.

Real-time breath gas analysis coupled to gas exchange modeling is emerging as promising strategy to enhance the information gained from breath tests. It is shown for exhaled breath carbon monoxide (eC...

Effects of Pulmonary Flow Heterogeneity on Oxygen Transport Parameters in Exercise.

Under resting normoxic conditions, the healthy lung has ample oxygen uptake capacity relative to oxygen demand, but during exercise, increased oxygen demand and utilization become increasingly depende...

Development of a New Method for Steady-State Measurement of NO Lung Diffusing Capacity in Healthy Subjects

Using a rapidly responding nitric oxide analyzer in a new developed modular lung-function-setup we are going to measure steady-state NO diffusing capacity in 107 healthy subjects (age 6-45...

Exhaled Carbon Monoxide (eCO) for Diffusing Capacity (DLCO) Correction

The purpose of this study is to check the accuracy of a procedure called exhaled carbon monoxide (eCO) testing. Exhaled carbon monoxide is used by physicians to help assess breathing in pe...

Medical and Biotech [MESH] Definitions

Carbon monoxide (CO). A poisonous colorless, odorless, tasteless gas. It combines with hemoglobin to form carboxyhemoglobin, which has no oxygen carrying capacity. The resultant oxygen deprivation causes headache, dizziness, decreased pulse and respiratory rates, unconsciousness, and death. (From Merck Index, 11th ed)

Controlled physical activity, more strenuous than at rest, which is performed in order to allow assessment of physiological functions, particularly cardiovascular and pulmonary, but also aerobic capacity. Maximal (most intense) exercise is usually required but submaximal exercise is also used. The intensity of exercise is often graded, using criteria such as rate of work done, oxygen consumption, and heart rate.

The amount of a gas taken up, by the pulmonary capillary blood from the alveolar gas, per minute per unit of average pressure of the gradient of the gas across the BLOOD-AIR BARRIER.

Toxic asphyxiation due to the displacement of oxygen from oxyhemoglobin by carbon monoxide.

The exercise capacity of an individual as measured by endurance (maximal exercise duration and/or maximal attained work load) during an EXERCISE TEST.
