Asthma is a common reason for admissions to the pediatric intensive care unit (PICU). Since June 2014, our institution has used a pediatric asthma clinical pathway for all patients, including those in PICU. The pathway promotes respiratory therapist-driven bronchodilator weaning based on the Modified Pulmonary Index Score (MPIS). This pathway was associated with decreased hospital length of stay (LOS) for all pediatric asthma patients; however, the effect on PICU patients was unclear. We hypothesized that the implementation of a pediatric asthma pathway would reduce hospital LOS for asthmatic patients admitted to the PICU. ⋯ The implementation of an asthma pathway was associated with decreased hospital LOS, PICU LOS, and time on continuous albuterol. There was also an increase in the use of high-flow nasal cannula and noninvasive ventilation after the implementation of this clinical pathway.

Pulse oximetry has become the standard of care in emergency medicine, operating rooms, and medical wards for the monitoring of oxygenation, but the use of pulse oximetry for assessment of hemoglobin (Hb) is controversial. The purpose of this study was to compare the accuracy and precision of 2 point-of-care Hb measurement devices, the Pronto-7 and the HemoCue 201+, to laboratory testing. ⋯ Both devices provided clinically useful methods to screen for anemia.

Carbon monoxide (CO) exposure causes roughly 40,000 emergency department (ED) visits annually and is commonly misdiagnosed. Whereas the standard method of carboxyhemoglobin (HbCO) measurement utilizes blood gas analysis, a noninvasive, FDA-cleared alternative exists. We evaluated the performance of pulse oximetry (SpCO) for identification of CO exposure in ED patients. ⋯ Pulse oximetry underestimated HbCO and produced false negative results (ie, SpCO < 10% for all three measurements) in 17% of ED subjects with elevated HbCO ≥ 15%. Triage screening with pulse oximetry detected cases of elevated HbCO that were not suspected by the clinical provider.

High-flow nasal cannula (HFNC), a form of noninvasive respiratory support, is effective for the treatment of respiratory distress in ICUs. Although HFNC has been used outside of the ICU, there is little research that examines its safety in this less-monitored setting. ⋯ HFNC may be a safe modality of respiratory support outside of the ICU for children ages ≤ 24 months with bronchiolitis and without comorbidities up to a maximum flow of 10 L/min. There were no adverse events among the subjects who were fed while on HFNC.

Chronic hypoxemia in patients with COPD is a limiting factor that is associated with disease progression and significantly contributes to decreased physical activity. Although correction of hypoxemia results in physiological improvements, oxygen therapy may be related to social isolation and inactivity. However, few studies have objectively investigated the level of physical activity in daily life (PADL) in these patients. The objective of this study was to compare the level of PADL in subjects with COPD on home oxygen therapy and in subjects with no oxygen therapy, and to investigate whether home oxygen therapy is associated with the level of PADL. ⋯ Subjects with COPD using oxygen at home showed reduced level of PADL. The results indicate that oxygen therapy is associated with severe physical inactivity and may be a predictor of the level of PADL.
