A cross-sectional survey on the lung ultrasound training and practice of respiratory therapists in mainland China.

Purpose: This national study aimed to investigate the lung ultrasound (LUS) training and practice of respiratory therapists (RTs) in mainland China.

Methods: A cross-sectional multicenter survey was conducted from May 22, 2021 to August 12, 2021, through online platforms. This survey included RTs in mainland China.

All-optic control using a photo-thermal heater in Si photonics.

We propose and demonstrate a simple all-optic control for Si photonics using a photo-thermal heater. The control light is absorbed in a heavily doped control waveguide and the signal light phase is tuned through thermal diffusion in a signal waveguide adjacent to but not optically coupled with the control waveguide. We designed and fabricated Mach-Zehnder- and microring-type devices requiring 17 (π-phase shift) and 4 (switching between resonance and non-resonance with 6 dB extinction) mW of control power, respectively.

Imaging of electromagnetic waves using a radio over fiber system including an Si photonics microring modulator array.

We propose an electromagnetic wave imaging system using Si photonics microring modulators (MRMs) as radio over fiber components. In this system, radio frequency signals detected at microwave probes are applied to the connected MRMs; an MRM is tuned to the laser wavelength using the thermo-optic effect to read-out through the optical transmission. By repeating this process for all MRMs and mapping the read-out signals in two dimensions, the distribution of electromagnetic waves can be visualized.

An updated HACOR score for predicting the failure of noninvasive ventilation: a multicenter prospective observational study.

Background: Heart rate, acidosis, consciousness, oxygenation, and respiratory rate (HACOR) have been used to predict noninvasive ventilation (NIV) failure. However, the HACOR score fails to consider baseline data. Here, we aimed to update the HACOR score to take into account baseline data and test its predictive power for NIV failure primarily after 1-2 h of NIV.

Association between ARDS Etiology and Risk of Noninvasive Ventilation Failure.

The etiology of acute respiratory distress syndrome (ARDS) may play an important role in the failure of noninvasive ventilation (NIV). To explore the association between ARDS etiology and risk of NIV failure. A multicenter prospective observational study was performed in 17 intensive care units in China from September 2017 to December 2019.

The Use of Aerosolized Medications in Adult Intensive Care Unit Patients: A Prospective, Multicenter, Observational, Cohort Study.

Only limited data are available on the real-life clinical utilization of aerosolized medications in intensive care unit (ICU) patients. Exploring the utilization of aerosolized medications in the ICU may contribute to develop appropriate education and improve the quality of aerosol therapy. A 2-week, prospective, multicenter, observational, cohort study was conducted to record how the aerosolized medications were utilized in the Chinese ICUs, including indications, medications used in solo or combination, dosage, and side-effects in adult patients.

Noninvasive ventilation failure in patients with hypoxemic respiratory failure: the role of sepsis and septic shock.

Background: Sepsis and septic shock are common in noninvasive ventilation (NIV) patients. However, studies on the association between sepsis and NIV failure are lacking.

Methods: A prospective multi-center observational study was performed in 16 Chinese intensive care units (ICUs).
