Pressure Injury
Conditions
Interventions
Experimental group:Set 1:1 oxygen mixture, which means a total flow of 2L/min of air and 2L/min of 100% pure oxygen, resulting in an inhalation concentration of 60%. It can be adjusted to a 1:1 ratio
Control group:Set a 3:1 oxygen mixture, which means a total flow of 3L/min of air and 1L/min of 100% pure oxygen, resulting in an inhalation oxygen concentration of 40%. It can be adjusted to a 3:1 ra
