“…In con trast to these previous findings in pleural fluid and in other tissue gas pockets [3,10,26], we have observed high Po2 levels suggesting equilibration with alveolar gas in occasional patients with congestive heart failure and in l patient with fibrothorax. This finding is in accord with the high Po, levels seen in pulmonary lymph and the assumption that the Po2 of the pul monary lymph as well as the interstitium is equal to the alveolar Po2 [30], Thus, Po2 determinations may under certain conditions and in contrast to previous re ports [10] also be of diagnostic value.…”

Effect of Thoracentesis on Arterial Oxygen Tension

et al. 1978

The acute effects of thoracentesis on arterial oxygenation were observed in 19 studies on 17 patients. Arterial blood samples were obtained prior to, immediately after, and 1 h after thoracentesis. Unpredictable changes in the arterial oxygen tension, ranging from – 22 to + 19 mm Hg were found immediately following thoracentesis. It was concluded that significant hypoxemia may result from thoracentesis due to aberration of ventilation-perfusion relationships. It is further suggested that oxygen therapy be routinely administered during and immediately after the procedure

“…Since the lymphatic vessels drain the interstitial spaces, several authors suggested that lymph might serve as a useful means to assess tissue oxygenation (Bergofsky et al, 1962;Cockett et al, 1966;Meyer and Ottaviani, 1972;Nagy et al, 1969;Said et al, 1965;W itte et al, 1967).

Oxygen tension of the small lymph vessels (PLO2) of the rabbit hind limb was measured with both a flow-through micro chamber and a polarographic catheter-tip oxygen electrode to obtain experimental data on the source of oxygen in the lymph. The following processes may influence PLO2: 1. Since the structure of the lymphatic capillaries allows a free diffusion of small molecules from the interstitial fluid into the lymphatics the lymph within its capillaries can mirror the oxygen supply of the tissue, i.e., probably a mean interstitial PO2. 2. PLO2 might be influenced by the oxygen content of the tissue surrounding the lymph vessels. Measurement with the catheter electrode showed that PLO2 rose after superfusing vessel with O2-saturated saline. After occlusion of the artery running paralled to the lymph vessel, a decrease in PLO2 was recorded. PLO2 in the absence of lymph flow increased rapidly after O2 inhalation. This reaction could be impeded by occluding the artery running parallel with the lymph vessel. 3. The mean oxygen tension of the prenodal (afferent) lymph measured with the flow-through chamber was 28.1 +/- 12.0 torr, whereas that measured with the catheter electrode was 42.0 +/- 12.18 torr. This difference may be attributed to the oxygen consumption of the lymph cells. The lymph containing a large number of cells has a stronger oxygen consumption than that with a lower number of cells. These observations suggest that PLO2 is influenced not only by the oxygen tension of the tissues drained by the lymph but also by the oxygen consumption of lymph cells as well as by the oxygen content of the surrounding tissues and perhaps by that of the blood vessels which are located at different distances from the collecting lymphatic vessels.

“…The lung has an extensive lymphatic network and, in the 30 years since the pioneering work of Warren and Drinker (2), the flow and composition of pulmonary lymph have been described in normal dogs and in dogs with various conditions associated with increased extravascular lung water (3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16). However, the factors which govern pulmonary lymph drainage are not fully understood.…”
