Pediatric ARDS continues to be a management challenge in the ICU with prolonged hospitalizations and high mortality. Thromboembolic pulmonary embolism and in situ pulmonary artery thrombosis might represent underappreciated thrombotic processes for a subset of these patients. Although well described in the adult literature, descriptions of pulmonary thromboses with pediatric ARDS are limited to case reports. ⋯ Observing an alveolar dead space fraction ≥ 0.25, or either a 50% increase in physiologic dead space/tidal volume or a central venous saturation ≤ 60% over 24 h, triggers the algorithm. Together with targeted heparin treatment and right ventricular afterload reduction, clinical outcomes might improve if this particular patient subgroup can be identified early. While anticoagulation is recommended in adults with confirmed pulmonary embolism and low early mortality risk, data for children are limited.

Lung ultrasound is a point-of-care imaging tool that is routinely used in acute care medicine. Traditionally, radiology physicians were the primary practitioners of diagnostic ultrasound, but with the recognition of its importance in intensive care medicine, critical care physicians have also adopted this practice. ⋯ Their scope of responsibility is expanding with newer technologies being brought into clinical use on a regular basis. This review focuses on the scope and benefits of ultrasound training within respiratory care-related areas.
