of them are performed via OSS [6]. In CSS,
without removing the patient from the
ventilator, the suction is done by preserving the
lung volume and providing oxygen
continuously. This would prevent
hemodynamic disturbances associated with the
reduction of oxygen during suction of the
endotracheal tube [9]. Moreover through
blocking the connection between the patient
and the ventilator during tracheal suction
operation, the environment, nurses and also the
patients would be preserved from pollution.
This would additionally prevent lung volume
reduction in patients with severe hypoxia.
Although it is costly, this procedure is regarded
economical since it is cheaper than OSS which
requires two nurses and gloves and a disposable
suction catheter [10]. Hospital nurses play a
very important role as the main caregivers of
patients. Therefore, improving the quality of
their service is the most important factor which
can accelerate healing patients [11]. Based on
the statistics obtained from intensive care unit,
in spite of the availability of CSS, about 80% of
personnel do not use it properly because they
believe that in CSS the suction intake is
inadequate. Since in intensive care units,
suction procedures are not among essential
operations and respiratory support for patients
is not among nurses’ main responsibilities, this
study aimed to "increase the willingness of
nurses toward CSS".
