Assessing Pulmonary Gas Exchange
New England Journal of Medicine, 1987IN these heady days of molecular biology, one almost needs to apologize for an interest in pulmonary gas exchange.

Abstract Ventilation delivers O2 to and removes CO2 from the lung. The circulation transports O2 and CO2 between the lung and the peripheral tissue. The mechanisms for the exchange of O2 and CO2 between the alveolar gas and pulmonary capillary blood are the subject of this chapter. These passive mechanisms can be influenced by outside

Clinical Science, 1980
In the last 2 years, comparatively little has been published in Clinical Science on pulmonary gas exchange. Nevertheless, the subject continues to generate a good deal of clinical and physiological research, much of it linked to the application of new techniques such as gas chromatography, radioactive gases and computers.

Current Opinion in Anaesthesiology, 1992
General anaesthesia may still cause severe hypoxaemia in more patients than expected. However, the causes of pulmonary dysfunction during anaesthesia have become more clear with shunt (caused by compression atelectasis) and ventilation/perfusion (A/) mismatch being the two major factors.

Pulmonary gas exchange in diving
Journal of Applied Physiology, 2009Diving-related pulmonary effects are due mostly to increased gas density, immersion-related increase in pulmonary blood volume, and (usually) a higher inspired Po2. Higher gas density produces an increase in airways resistance and work of breathing, and a reduced maximum breathing capacity.

Pentoxifylline Improves Pulmonary Gas Exchange
Chest, 1990Pentoxifylline is a xanthine derivative with hemorrheologic and vascular properties that may improve gas exchange in patients with chronic obstructive pulmonary disease (COPD). We tested this hypothesis in 12 patients with COPD (mean FEV1 = 40 percent predicted; mean DCO, 8.6 ml/min/mm Hg) randomly divided into a treatment and control group and six ...

Pulmonary Embolism and Gas Exchange
Respiration, 2019Acute pulmonary embolism (PE) impairs hemodynamics, gas exchange, and lung mechanical capacity. Considering PE pathophysiology, most attention has been paid to hemodynamic impairment. However, the most prevalent symptoms in PE patients come from gas exchange alterations, which have not been in the spotlight for many years.

Pulmonary gas exchange in hypothyroidism
Pneumonologie Pneumonology, 1974In 7 normocapnic patients with hypothyroidism pulmonary gas exchange was measured before and after successful hormonal treatment. The results were compared with those of 8 healthy control subjects matched with the patients made euthyroid by treatment in relation to their age, sex, body height, and body weight.

The ultimate goal of the respiratory system is to exchange oxygen (O2) and carbon dioxide (CO2), to meet the metabolic needs of the body. In order to properly transfer both gases, ventilation and blood flow must be adequately apportioned and matched within the lungs. Of the four classic mechanisms determining abnormal arterial blood respiratory gases —

In the original sense of the latin word, “respiration” means repeated inhaling and exhaling of air with the associated movements of the thorax. Respiratory movements produce air flow for the transport of O2 into lungs, and of CO2, the end product of oxidative metabolism, out of the lungs.
