The need for long-term oxygen therapy (LTOT) is usually a sign of advanced disease, which could trigger advance care planning. However, LTOT is used in patients with different characteristics and multiple diagnoses beyond COPD. We studied the factors associated with survival in an unselected sample of subjects who started LTOT. ⋯ The survival of the subjects who started LTOT varied greatly. The subjects with interstitial lung disease and those who required assistance with activities of daily living were at risk of dying in ∼1 y, which suggested that advance care planning should be directed especially to these patients.

Noninvasive ventilation (NIV) reduces intubation and mortality in patients with COPD exacerbation who present with respiratory failure, and the type of mask may affect its success. Our objective was to compare the performance of 3 different NIV masks in a lung model. ⋯ In this model, we found that the type of mask had no impact on CO2 washout or on most synchrony variables.

High-flow nasal cannula (HFNC) oxygen therapy is a routine, evidence-based treatment in the ICU. Due to its ease of application, non-evidence-based use of HFNC has spread to non-ICU wards. This study reports on the experience with HFNC outside the ICU. ⋯ HFNC outside the ICU was associated with improved visual analog scale score, breathing frequency, and saturation but with a relatively high mortality, even in non-DNR subjects. HFNC was used in many subjects who had a DNR order. This therapy may have been palliative in intent. Care should be exercised in using this therapy in a setting that is not continuously monitored.

Clinicians may use adventitious breath sounds on lung auscultation and a "sawtooth" pattern on the ventilator expiratory flow waveform as indicators of the need for chest physiotherapy for airway-secretion clearance in mechanically ventilated patients. This study seeks to identify potential clinical and novel indicators of the weight of airway secretions cleared from a single session of chest physiotherapy in mechanically ventilated subjects. ⋯ Simple clinical assessments used in this study were able to independently predict the weight of airway secretions cleared during a single session of chest physiotherapy. The novel assessments used in this investigation did not add any further value.

Status asthmaticus is one of the most frequent admission diagnoses in the pediatric ICU (PICU). Collaboration between respiratory therapists (RTs) and physicians may help efficiently deliver care to a patient in status asthmaticus. The Pediatric Asthma Severity Score (PASS) is a measure of severity of a patient's asthma exacerbation at a point in time. The aim of this quality improvement initiative was to establish an RT-driven continuous albuterol weaning protocol using the PASS score. We hypothesized that this would decrease the duration of continuous albuterol without increasing adverse events. ⋯ An interprofessionally-developed, RT-driven continuous albuterol weaning protocol can be implemented without negatively impacting duration of continuous albuterol or PICU length of stay and without increasing adverse events.
