A random sampling method was used to select one of the three pressure groups (low\u2010, medium\u2010 and high\u2010pressure groups). Registered intensive care unit (ICU) nurses performed open suction manoeuvres of the artificial airway based on the pressures set by the researchers. Two teaching supervisors observed and recorded the sputum viscosity, suction pressure, minimum intracatheter pressure, maximum intracatheter pressure, heart rate, mean arterial pressure, pulse oxygen saturation, airway mucosal bleeding and sputum sound improvement score.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>This study finally included 438 patients. The results showed that the safe and effective suction pressures were 80\u2013120\u2009mmHg for grade I sputum viscosity, 150\u2009mmHg for grade II sputum viscosity and 200\u2009mmHg for grade III sputum viscosity in open suction procedures for ICU patients. These pressure values were associated with the lowest changes in heart rate, mean arterial pressure and pulse oxygen saturation; the lowest incidence of airway mucosal bleeding; and the highest sputum sound improvement score.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>In an open
