Introduction:  The  proportion  of  old  inpatients  in  cardiac  intensive  care  units  (CICUs)  is increasing.
Objectives:  This  study  was  conducted  to  determine  the  relationship  of  hemodynamic  and oxygenation status with the risk of pressure ulcers following open heart surgery in old patients.
Patients and Methods: The present descriptive study was conducted over three months in 2016 on 48 patients selected using convenience sampling. The data collection tools included a three-part demographic information checklist, hemodynamic clinical data collection forms, oxygenation
clinical data collection forms and the Braden scale. The data collected were analyzed in SPSS using descriptive tests, the independent t test and Pearson’s correlation coefficient.
Results: Of the 48 patients, 28 (58.3%) were male and 20 (41.7%) were female. The mean age of the patients was 68.16 ± 5.53 years and their mean length of stay was 2.95 ± 0.96 days. All the pressure ulcers were stage 1 and 2. The incidence of pressure ulcers in these patients was
found to have statistically significant relationships with the mean heart rate on the second day (P = 0.01), the mean arterial carbon dioxide level on the fourth day (P = 0.02), diabetes (P = 0.01) and  smoking  (P = 0.001),  while  it  lacked  statistically  significant  relationships  with  the  other
hemodynamic and oxygenation variables studied.
Conclusion: Old patients undergoing open heart surgeries are at a high risk of the incidence and development of pressure ulcers. Thus, factors such as diabetes, smoking, heart rate and arterial carbon dioxide level affect the incidence of these ulcers.


Core tip
Old  patients  undergoing  open  heart surgeries are at a high risk of the incidence and  development  of  pressure  ulcers. Consequently,  factors  such  as  diabetes, smoking,  heart  rate  and  arterial  carbon dioxide  level  affect  the  incidence  of  these ulcers.
