Patient response to transtracheal oxygen delivery.

We compared the effectiveness of transtracheal oxygen delivery with that of nasal cannula delivery in 10 subjects with severe hypoxemia who had previously used a portable liquid oxygen system for 20 +/- 12 months. Arterial blood gas measurements, spirometry, and an exercise test were performed prior to catheter insertion and at 2 and 6 months after insertion. With transtracheal oxygen delivery, subjects significantly (p less than 0.0001) reduced their oxygen requirement while maintaining previous exercise capacity. No change occurred in pH, PaCO2, or in spirometry. Of the 10 subjects, 4 have continued catheter use with excellent acceptance. Three experienced complications after insertion, which necessitated catheter removal. Two elected to discontinue the catheter despite subjective improvement in dyspnea. One subject died after an exacerbation of COPD. Our experience confirms findings of others that transtracheal oxygen delivery significantly reduces oxygen requirement. However, in this study, we encountered complications requiring removal of the catheter and variability in patient acceptance. Results indicate the need for additional controlled studies to identify which patients will benefit most from those potentially promising system for delivery of chronic oxygen therapy.

Ineffective breathing pattern related to malnutrition.

This article has highlighted the problem of malnutrition in the stable COPD patient and the critically ill, hypercatabolic patient, and has reviewed resultant mechanisms which influence the alteration of breathing pattern. These complex patients present a challenge for the nurse. Table 1 briefly summarizes the manifestations of malnutrition, goals, interventions and expected outcomes of the nursing diagnosis, ineffective breathing pattern related to malnutrition. The goal of the interventions is to modify the cause (malnutrition) of the nursing diagnosis (altered breathing pattern). The success of the interventions will lead to the achievement of expected outcome As expected outcomes are achieved, relief of signs and symptoms related to the nursing diagnosis will occur. The nurse caring for the patient with actual or potential malnutrition must be knowledgeable about the physiology of malnutrition and effect on breathing pattern. It is essential that the nurse assess and provide appropriate nutritional support and evaluate progress toward expected outcomes. In the event that expected outcomes are not achieved, reassessment with modification of interventions is necessary. Nurses play a key role in the total health care delivery to these complex patients. Further study will strengthen the research base of nursing interventions.

Nutritional status and lung function in patients with emphysema and chronic bronchitis.

This study compared the nutritional status of patients with emphysema and chronic bronchitis and examined the relationship between lung dysfunction and nutritional depletion in patients with emphysema. There was no evidence of nutritional depletion in patients with chronic bronchitis (n = 4). In contrast, patients with emphysema (n = 14) were somatically depleted. They exhibited lower values for percent ideal body weight (%IBW), arm muscle circumference (AMC), and triceps skin fold thickness (TSF) (p less than 0.05) than did patients with chronic bronchitis. The creatinine height index (CHI) was also lower in this group, but the difference was not significant (p = 0.08). In patients with emphysema, there was a good correlation between the degree of airflow obstruction and of somatic depletion (FEV1 vs %IBW, r = 0.699, p less than 0.001). The single-breath diffusing capacity (DCO) also correlated well with %IBW (r = 0.6052, p less than 0.019). These results confirm that patients with emphysema are frequently nutritionally depleted and suggest that nutritional depletion contributes to lung dysfunction in emphysema.
