Ultrasound may be useful to assess the structure, activity, and function of the abdominal muscles in patients who are mechanically ventilated.

The United States Chronic Thromboembolic Pulmonary Hypertension Registry (US-CTEPH-R) was designed to characterize the demographic characteristics, evaluation, clinical course, and outcomes of surgical and nonsurgical therapies for patients with chronic thromboembolic pulmonary hypertension.

Frailty is associated with poor outcomes in critical illness. However, it is unclear whether frailty screening on admission to the ICU can be conducted routinely at the population level and whether it has prognostic importance.

GATA2 deficiency is a genetic disorder of hematopoiesis, lymphatics, and immunity caused by autosomal dominant or sporadic mutations in GATA2. The disease has a broad phenotype encompassing immunodeficiency, myelodysplasia, leukemia, and vascular or lymphatic dysfunction as well as prominent pulmonary manifestations.

Although specific interventions previously demonstrated benefit in patients with ARDS, use of these interventions is inconsistent, and patient mortality remains high. The impact of variability in center management practices on ARDS mortality rates remains unknown.

There is an urgent need for population-based studies on managing patients with pulmonary nodules.

We describe a request for CPR without chest compressions from a patient's daughter. Requests for partial codes raise numerous clinical concerns, including lack of evidence-based effectiveness, risk of medical error, and difficulty in communication. These in turn lead to ethical concerns, including a misapplication of respect for patient autonomy, violating the foundational principle of "first do no harm," and inconsistency with the tenets of shared decision-making. Many requests for partial codes are also based on a conflation of cardiopulmonary arrest and pre-arrest emergencies. We argue physicians have no ethical obligation to honor a request for a partial code and that doing so does not violate respect for patient autonomy. Requests for partial codes should be seen as a request for information about CPR and an invitation to conversation. We also report here the move our health system made to only offer evidence-based code status options and reject those with negligible likelihood for therapeutic benefit. This work included limiting options for code status to "Full Code" or "Do Not Attempt Resuscitation," creating an order set for non-arrest emergencies, and sample language to guide physicians in responding to requests for partial codes. To assist other hospitals or health systems considering this move, we provide the content of the order set for non-arrest emergencies and the sample language guide.

The COVID-19 pandemic resulted in unprecedented adjustments to ICU organization and care processes globally.

Unilateral stimulation of the hypoglossal nerve may result in clinically valuable patency of the upper airway in well-selected patients for treatment of OSA. The Food and Drug Administration has established stringent criteria for the placement of this medical device. The treatment is a consideration among patients who have been nonadherent or intolerant of positive airway pressure therapy, with moderate to severe OSA, and a BMI of ≤ 32 kg/m2. Some of the insurance providers have lowered BMI guidelines to allow implantation in patients with a BMI of < 35 kg/m2. Further, a clinical assessment with sleep endoscopy is available to define proper anatomic features and to determine, based on the results, if the patients are appropriate surgical candidates. Current Procedural Terminology codes that are specific to the placement as well as removal or replacement of the device, or both, are discussed, as well as sleep medicine-related evaluation and management.

The short- and long-term prognosis of Takotsubo syndrome (TTS) presenting with right ventricular (RV) involvement remains poorly understood.

Infant pulmonary function tests (iPFTs) in subjects with neuroendocrine cell hyperplasia of infancy (NEHI) have demonstrated substantial expiratory airflow obstruction and air trapping.
