Australian researchers split ventilators for COVID-19

Australian researchers have found that in cases of “extreme emergencies,” a single ventilator could be used between multiple patients of COVID-19 who require ventilator support. These ventilators could be split between the critically ill patients with not only COVID-19 but also other respiratory illnesses, the team of Australian researchers found. The study titled, “'Ventilator splitting with differential driving pressures using commodity hospital equipment,” was published in the latest issue of the journal Anaesthesia.

Hypertensive patients on ACE inhibitors and angiotensin receptor blockers may have improved COVID-19 prognosis

Emerging concerns that common antihypertensive treatment approaches with angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) – jointly known as renin-angiotensin-aldosterone system (RAAS) inhibitors – may exert a negative effect in COVID-19 patients are not grounded in scientific evidence, as reported by researchers in a recent review article published in Mayo Clinic Proceedings journal.

Novel coronavirus targets specific secretory cells in the lungs

Viruses attack specific host cells, which can cause chaos in the body. The novel coronavirus, now called severe acute respiratory syndrome coronavirus 2 or SARS-CoV-2 for short, infects respiratory epithelial cells in the lining of the lung, causing difficulty of breathing. The usual cause of death of those who contract the virus is pneumonia and acute respiratory distress syndrome (ARDS). Now, a new study has found that SARS-CoV-2 specifically attack certain progenitor cells called bronchial transient secretory cells in the lungs.
