A diagnostic software tool for determination of complexity in respiratory pattern parameters
No full textThe development and validation of a software that is user friendly and flexible in determining approximate entropy and reflecting complexity in respiratory pattern parameters are presented. The report includes the theory and computational methods for approximate entropy as well as the system description and software architecture. Results for a simulated periodic and regular respiratory pattern as well as for an irregular and complex breathing pattern obtained from a patient receiving mechanical ventilation in the intensive care unit are provided. By providing easy and rapid determination of the approximate entropy, the software enables health care professionals to understand how specific mechanical ventilation settings influence the respiratory pattern for patients receiving mechanical ventilation in the intensive care unit and ultimately identify the reversibility of respiratory diseases and weaning and liberation from mechanical ventilation. © 2007 Elsevier Ltd.

A New Oxygenation Index for Reflecting Intrapulmonary Shunting in Patients Undergoing Open-Heart Surgery
No full textStudy objectives: To assess the reliability of new and traditional oxygenation measurements in reflecting intrapulmonary shunt. Design: Prospective study. Setting: Cardiac surgery unit at a university hospital. Patients: Fifty-five patients undergoing coronary artery bypass grafting. Measurements and results: Simultaneous blood samples were collected from an indwelling arterial line and a catheter for determination of blood gases. Standard accepted formulas were utilized to measure a new oxygenation index: PaO2-fraction of inspired oxygen (FIO2) x mean airway pressure (Paw). The standard formulas used were the oxygenation ratio (PaO 2-FIO2), PaO2-alveolar partial oxygen pressure (PAO2), alveolar-arterial oxygen tension gradient (P[A-a]O 2), and intrapulmonary shunt (venous admixture [Qsp-Qt]). There were significant negative (p andlt; 0.05) correlations between the PaO 2-(FIO2 X Paw) and Qsp-Qt (r = - 0.85), between the PaO2-FIO2 and Qsp-Qt (r = - 0.74), and between the PaO2-PAO2 and Qsp-Qt (r = - 0.71). There was a significant positive (p andlt; 0.05) correlation between the P(A-a)O2 gradient and Qsp-Qt (r = 0.66). However, the correlation was strongest between the PaO2-(FIO2 x Paw) and Qsp-Qt. Conclusion: In this group of patients, PaO2-(FIO2 x Paw) might be more reliable than other oxygenation measurements in reflecting intrapulmonary shunt.Brower RG, 2000, NEW ENGL J MED, V342, P1301; BAIGELMAN W, 1984, CRIT CARE MED, V12, P486, DOI 10.1097-00003246-198406000-00003; BERNARD GR, 1994, AM J RESP CRIT CARE, V149, P818; BERTHELSEN P, 1986, ACTA ANAESTH SCAND, V30, P243; BONE RC, 1989, CHEST, V96, P849, DOI 10.1378-chest.96.4.849; CANE RD, 1988, CRIT CARE MED, V16, P1243, DOI 10.1097-00003246-198812000-00014; CHATBURN R, 1990, HDB RESP CARE; COVELLI HD, 1983, CRIT CARE MED, V11, P646, DOI 10.1097-00003246-198308000-00012; DOWNS JB, 1976, CRIT CARE MED, V4, P295, DOI 10.1097-00003246-197611000-00002; Dyhr T, 2002, ACTA ANAESTH SCAND, V46, P717, DOI 10.1034-j.1399-6576.2002.460615.x; Gould MK, 1997, CRIT CARE MED, V25, P6, DOI 10.1097-00003246-199701000-00005; Gowda MS, 1997, CRIT CARE MED, V25, P41, DOI 10.1097-00003246-199701000-00010; Hess D., 1985, RESP CARE, V30, P961; HOFFSTEIN V, 1984, J LAB CLIN MED, V104, P685; HOROVITZ JH, 1974, ARCH SURG-CHICAGO, V108, P349; MARVEL SL, 1986, CHEST, V90, P537, DOI 10.1378-chest.90.4.537; MURRAY JF, 1988, AM REV RESPIR DIS, V138, P720; Nirmalan M, 2001, BRIT J ANAESTH, V86, P477, DOI 10.1093-bja-86.4.477; NUNN JF, 1993, APPL RESP PHYSL; RASANEN J, 1987, CRIT CARE MED, V15, P1058; ROBINSON N B, 1981, American Review of Respiratory Disease, V123, P92; SIGGAARDANDERSEN O, 1995, ACTA ANAESTH SCAND, V39, P41; SUTER PM, 1978, HERZ, V3, P198; SYDOW M, 1994, AM J RESP CRIT CARE, V149, P1550; VALTA P, 1992, CHEST, V141, P281; VIALE JP, 1986, CRIT CARE MED, V14, P153, DOI 10.1097-00003246-198602000-00018; ZETTERSTROM H, 1988, ACTA ANAESTH SCAND, V32, P57920151
Buspirone treatment for apneustic breathing in brain stem infarct
No full textWe report a case of brainstem infarction resulting in apneustic breathing, which was alleviated with buspirone. We discuss apneusis, review the literature, and speculate about the benefit of serotonin 1A receptor agonists in the treatment of apneusis and other respiratory disorders. © 2003 Daedalus Enterprises.1
The value of pulmonary function testing in bone marrow transplantation
No full textIntroduction: The pre- and postbone marrow transplant pulmonary functions testing are widely used as standard clinical practice. However, whether there is sufficient reliable data to support and validate this practice is not confirmed. Objective: In this article we will review the publications that have assessed the role of pretransplant pulmonary functions tests for bone marrow transplant patients in identifying those patients who are at high risk for developing posttransplant noninfectious pulmonary complications. Methods: PubMed search to identify the publications that have investigated the role of pretransplant pulmonary functions tests in predicting posttransplant pulmonary complication in patients undergoing bone marrow transplant. Results: Several small studies suggest a risk of posttransplant complications associated with pretransplant obstructive patterns. Conclusion: Large randomized control trials examining pretransplant lung function are needed, including both nonmyeloablative and myeloablative conditioning regimens, to determine how pretransplant pulmonary function data can be applied clinically to reduce patient risk for significant pulmonary complications and mortality
