This study is aimed to examine the effect of different wound dressings on the prevention of pressure injury in the face area related to noninvasive mechanical ventilation mask. The study was completed out with 102 patients who were followed up in Chest Diseases and Thoracic Surgery Hospital between October 2019 and August 2020 and met the inclusion criteria of the study. In the study, hydrocellular and hydrocolloid wound dressing was applied to the pressure areas under the mask of noninvasive mechanical ventilation in the intervention groups, while the routine treatment process was followed in the control group. Wound dressings were obtained from HARTMANN. Study data were collected with the "Individual Characteristics Form" and "Pressure Injury Rating Scale".

In the hospital where the study was conducted, patients with respiratory failure receive NIMV treatment with an oro-nasal mask. In the study, hydrocolloid and hydrocellular wound dressings were placed on the pressure areas under the mask of the patients in the intervention group. NIMV treatment was applied to the face area of the patients in the control group with an oronasal mask without using any barrier cover. The pressure areas of the patients in the intervention and control groups were evaluated with the pressure injury scale before and after the NIMV treatment. Follow-up was carried out twice a day for 7 days.

Inclusion Criteria:

• over 18 years, receiving NIMV therapy for at least 6 hours a day, on the first day of hospitalization and followed up for at least 7 days, receiving NIMV treatment with an oro-nasal mask, tolerant of mask,

Exclusion Criteria:

• patients with pre-treatment pressure injuries in the facial area, patients with diabetes mellitus, patients with mental or psychological problems

It will be presented as a Clinical Study Report.

It will be used in the period from the completion of the study to the publication of the article (average 15 months).
