Background: Patients may require vasoactive medication after cardiac surgery. The effect and safety profile of exercise on haemodynamic parameters in these patients is unclear.
Objectives: The objective of this study was to measure the effect of upright positioning and low-level exercise on haemodynamic parameters in patients after cardiac surgery who were receiving vasoactive therapy and to determine the incidence of adverse events.
Purpose: Endotracheal suctioning (ES) of mechanically ventilated patients decreases end-expiratory lung volume (EELV). Manual hyperinflation (MHI) and ventilator hyperinflation (VHI) may restore EELV post-ES but it remains unknown which method is most effective. The primary aim was to compare the efficacy of MHI and VHI in restoring EELV post-ES.

Objective: This study aimed to investigate the safety of exercise rehabilitation of mechanically ventilated patients and evaluate the consensus recommendations.
Methods: This was a prospective, single-centre, cohort study conducted in a specialist cardiothoracic intensive care unit of a tertiary, university affiliated hospital in Australia.
Purpose: Speaking valves (SV) are used infrequently in tracheostomised ICU patients due to concerns regarding their putative effect on lung recruitment. A recent study in cardio-thoracic population demonstrated increased end-expiratory lung volumes during and post SV use without examining if the increase in end-expiratory lung impedance (EELI) resulted in alveolar recruitment or potential hyperinflation in discrete loci.
Materials And Methods: A secondary analysis of Electrical Impedance Tomography (EIT) data from a previous study was conducted.
Background. Lung transplantation is the optimal treatment for end stage lung disease. Donor shortage necessitates single-lung transplants (SLT), yet minimal data exists regarding regional ventilation in diseased versus transplanted lung measured by Electrical Impedance Tomography (EIT).

Whilst a speaking valve (SV) can be used on a tracheostomy tube, its use in ventilated ICU patients has been inhibited by concerns regarding potential deleterious effects to recovering lungs. The objective of this study was to assess end expiratory lung impedance (EELI) and standard bedside respiratory parameters before, during and after SV use in tracheostomised patients weaning from mechanical ventilation.

Methods: A systematic literature review was followed by a meeting of 23 multidisciplinary ICU experts to seek consensus regarding the safe mobilization of mechanically ventilated patients.
Results: Safety considerations were summarized in four categories: respiratory, cardiovascular, neurological and other.
Background: Head-of-bed elevation (HOBE) has been shown to assist in reducing respiratory complications associated with mechanical ventilation; however, there is minimal research describing changes in end-expiratory lung volume. This study aims to investigate changes in end-expiratory lung volume in a supine position and 2 levels of HOBE.
Methods: Twenty postoperative cardiac surgery subjects were examined using electrical impedance tomography.
Background: Airway suctioning in mechanically ventilated patients is required to maintain airway patency. Closed suction catheters (CSCs) minimize lung volume loss during suctioning but require cleaning post-suction. Despite their widespread use, there is no published evidence examining lung volumes during CSC cleaning.
View Article and Find Full Text PDFPurpose: Endotracheal suctioning causes significant lung derecruitment. Closed suction (CS) minimizes lung volume loss during suction, and therefore, volumes are presumed to recover more quickly postsuctioning. Conflicting evidence exists regarding this.
