Depending on the health needs of the resident, these could include one or more of the following: A respiratory module containing oxygen supplementation.Non-invasive positive pressure ventilation (CPAP and BIPAP), and nebulized medications.A renal module containing equipment for home hemodialysis or peritoneal dialysis.A feeding module containing an IV support and ancillary equipment required for a nocturnal enteral feeding system via a nasogastric tube.

The secondary outcomes included duration and success rate of insertion, tests to evaluate the placement and positioning of the devices, airway manipulations required to correct device malposition, intraoperative, and postoperative airway complications. The duration of SAD insertion was defined as the time from which the SAD was picked up to the time it was correctly placed with two effective end-tidal capnography waveforms. To evaluate the placement and positioning of the devices, several tests were performed. Ventilation test observed three indicators during mechanical ventilation, including positive pressure ventilation with a peak inspiratory pressure below 20 cmH2O, movement of the chest, and waveforms of carbon dioxide on capnography [10]. Suprasternal notch (SSN) test was done by placing a 1-cm gel plug in the proximal opening of the gastric draining channel and gentle tapping of SSN with a finger [11]. A positive SSN test was defined as the gel moving synchronously with suprasternal pressure, indicating the presence of the SAD tip behind the cricoid cartilage and a correct placement of the device [11].

Respirators used within the Inpatient Nursing Unit(s) were associated with high use roles, as defined by frequent and in-close proximity to suspected or confirmed positive COVID-19 patients and having frequent risk for exposure to aerosol-generating procedures. Staff in these roles wore EHMRs unless they failed to meet a qualitative fit test requirement. If this occurred, they were permitted to be evaluated with other forms of respiratory protection such as an N95 FFR for use. Aerosol-generating procedures included: intubation, extubation, bronchoscopy, noninvasive positive pressure ventilation, cardiopulmonary resuscitation, and sputum induction. Staff was required to wear a full faceshield over the EHMR in accordance with hospital policy and based on a risk assessment. Each time the HCP doffed the respirator, the facepieces and outside of the respirator filter cartridge bodies were disinfected with an EPA-approved disinfecting agent as described in Section II. Cleaning and Disinfection of EHMRs and Low Profile P100 Respirator Filter Cartridges.

Berenstein et al. [28] in their series of 16 neonatal patients, reported that after antenatal diagnosis of VOGM by prenatal ultrasound, often followed by MRI, patients underwent antenatal evaluation by a pediatric cardiologist with fetal ultrasound and echocardiography (to assess fetal heart size and associated heart defects). Berenstein et al. [28] have reported a protocol for maternal dosing of digoxin that produces stable therapeutic levels of digoxin in the neonate. More specifically, when the exams demonstrate that the ratio of the cross-sectional area of the fetal heart in a 4-chamber view to the cross-sectional area of the chest is 0.5 or more (normally the heart cross-sectional area is one-third of the cross-sectional area of chest), the mother is started on digoxin, under cardiac monitoring. The dose is 0,5 mg intravenously every 4 hours until a maternal serum level of close to 2 ng/dL is reached. Then, digoxin is switched to oral maintenance dose (usually 0.5 mg twice daily) and the serum level of digoxin is maintained at 2 ng/dL until delivery [28]. After birth, the neonate is immediately transferred in Neonatal Intensive Care Unit and if necessary, respiratory support with positive-pressure ventilation or intubation is initiated [28].
