Patient reactions associated with disconnection of the ventilator circuit during inhalation and filter change (English)
Abstract [sv]

Respiratorbehandling är vanligt hos intensivvårdspatienter. Positive end-expiratory pressure används för att förbättra syresättningen och hålla lungan öppen. Isärkoppling av respiratorslangar under respiratorbehandling innebär risk för försämrat gasutbyte och infektion. Dessutom orsakar det obehagliga upplevelser för patienten. Studien syftar till att kartlägga patientreaktioner före, under och efter isärkoppling av respiratorslangarna. Studien är genomförd som en strukturerad observationsstudie i två delar. Filter- och inhalationsmomentet samt frekvens av isärkopplingar har studerats. Medelvärdet för isärkopplingar under 24 timmar var åtta per patient. Hos tre (n=21) av observationerna sågs direkta reaktioner i samband med filterbyte. Hos 13 (n=18) av observationerna sågs direkta reaktioner i samband med något eller båda momenten av inhalation. Innan filterbyte och inhalation visade inte någon observation på en saturation < 95 %. Vid registrering 30 minuter efter filterbyte sågs två (n=21) i observationer en saturation < 95 % (93 %). 30 minuter efter inhalation sågs fem (n=17) observationer med en saturation < 95 % (91-94 %). Materialet är för litet för att dra några slutsatser men det är möjligt att en minimering av antalet isärkopplingar från respiratorn är till fördel för patienterna.

Abstract [en]

Ventilator therapy is common in ICU patients. Positive end-expiratory pressure is used to improve oxygenation and to keep the lung open. Disconnection of the ventilator circuit during ventilator therapy carries a risk for impaired gas exchange and of infection. It may also cause unpleasant experiences for the patient. The intention of this study was to identify patients' reactions before, during and after disconnection of the ventilator circuit. It was conducted as a structured observational research in two parts. Filter- and inhalation interventions and frequency of ventilator circuit disconnection have been studied. Average number of disconnections during 24 hours was eight per patient. At three (n=21) of the observations direct reactions was seen in connection with filter change. At 13 (n=18) of the observations direct reactions was seen at either or both connection and disconnection of inhalation. None of the observations showed a saturation < 95 % before intervention. At registration 30 minutes after filter change two observations were seen with a saturation <95 % and after inhalation five (n=17) observations showed a saturation < 95 %. The number of patients in this study was small but it is likely that minimizing the number of disconnections of the ventilator circuit is of benefit to the patients.
