In a statement, company chief executive Jenny Freeman said: “Respiratory depression continues to be a threat to patient safety and a leading source of added costs across the continuum of care in the hospital. Signs of respiratory risk often originate in the recovery room, ripple onto the general ward, and can continue post-discharge with the resulting significant cost burden for hospitals apparent at all levels – from the board of trustees to CFOs and all the way down the line. Higher incidence of obesity, sleep apnea, and use of opioids exacerbate the problem, while the current standard of care has proven insufficient. The best way to attack this is at the perioperative source.”
