[Effectiveness of the concentrator as a supply source in home oxygen therapy].

The oxygen concentrator is an effective supply source in home oxygen-therapy (HO). In order to study the effectivity of the concentrator in HO, we visited at home 31 patients using the concentrator as the only oxygen supply source in the exit gas and counted the hours of concentrator usage. Only 13 concentrators (41.9%) supplied a percentage of oxygen higher than 87% at a flow of two liters per minute. In three cases (9.7%), sporadic control measures of the percentage of oxygen in the exit gas were being taken and only four patients (12.9%) said that these controls were made monthly. The concentrator did not supply the adequate percentage of oxygen in 12 out of the 29 patients correctly taking the HO, so the effectivity of the treatment can only be expected in 28.6% of studied cases. The concentrator operates well under ideal conditions, but potential breakdowns in standard conditions of use must be considered. The efficiency of the HO with concentrator in our environment is very low, but it can be improved with regular controls of the concentrators or the introduction of devices warning the patient when they detect a reduction of the percentage of oxygen in the exit gas.

Acute respiratory failure in severe hematologic disorders.

The development of acute respiratory failure (ARF) in patients with hematologic disorders (HDs) is a life-threatening condition which does not respond well to intensive therapy. We present our experience in the use of intensive therapy for a group of 30 patients suffering from leukemia (21 cases), bone-marrow aplasia (6 cases), or lymphoma (3 cases). Seven had undergone bone-marrow transplantation. All 30 patients were hypoxemic and responded poorly to the administration of high oxygen concentrations via face mask. All were admitted to our intensive respiratory unit (IRU), where 26 received oxygen via mechanical ventilation, and 4 received continuous positive airway pressure (CPAP). Definitive diagnosis was established in 19 (63%) patients. A premortem diagnosis obtained in 8 (26%) cases did not change therapy. The diagnostic accuracy of serology and transbronchial biopsy was low. Of the 6 (20%) patients who recovered from ARF, only 2 were discharged from the hospital. The remaining 24 (80%) patients died in the IRU.

Hypophosphatemia as a cause of failed weaning: the importance of metabolic factors.

Hypophosphatemia has been only occasionally implicated as the cause of respiratory failure. This report illustrates its pathogenetic importance in the maintenance of such condition, as well as the importance of obtaining and maintaining normal values of the serum phosphorus level to achieve successful weaning. The relationship between maximum inspiratory pressure and the patient's inorganic phosphate level is presented (r = .97; p less than .01).
