Current NIV study: Combined use of face and nasal masks
A nasal mask such as the new ClassicStar may provide increased
patient comfort during non-invasive ventilation (NIV)
Lübeck – Indisputably, NIV therapy is now widely used for mechanical
ventilation purposes of patients suffering from acute respiratory
insufficiency. Evidence shows that, in many cases, the traditional face
mask is the first choice in terms of initial NIV treatment. After 24 to 48
hours of non-invasive ventilation, using a nasal mask instead may well
be appropriate for stable patients and provide increased treatment
comfort1. With ClassicStar, available as either ventilated or nonventilated
nasal masks, Dräger now offers hospitals a complete portfolio
of NIV masks.
In comparison to face masks, nasal masks generally offer the advantage that
they prevent sputum from remaining in the mask body and thus from entering
the respiratory tract of the patient. In addition, nasal masks also allow patients
to talk2. To sum it all up: Nasal masks offer patients more freedom. The aim of
a prospective, randomized and controlled clinical study was to investigate the
treatment course of non-invasive ventilation using a face mask and,
alternatively, a nasal mask. Two patient groups of 90 subjects in total,
suffering from hypercapnic acute respiratory failure participated in this study1.
Following the evaluation of the results, the recommendation was as follows:
The face mask is suitable for use during the initial non-invasive treatment
phase to prevent possible oral leakages. Using a nasal mask may well be an
option to be considered, providing the patient is in a stable condition after 24
to 48 hours. This helps to reduce side effects such as skin irritations, ear and
neck strain, which were observed following extended wearing of face masks,
and may, therefore, provide increased patient comfort. Another result of the
study was: Concerning the successful treatment of hypercapnic acute
respiratory failure, using a nasal mask – providing the absence of larger
leakages – may deliver as good a result as the use of a face mask does.
Optimal adaptation due to flexible air cushion body
In the development of the new, single-use Dräger ClassicStar nasal masks
emphasis was placed on minimizing the risk of skin irritations and pressure
marks that can be caused as much as possible. The air cushion, which can be
inflated and deflated by means of a pumping ball, allows to individually adjust
the mask to the patient's facial contours. The adjustable mask cushion as well
as the variable forehead support and the forehead pad provide better sealing
and a higher degree of wearing comfort at the same time. Three sizes are
available. A separate Dräger size template makes it easy to determine the
patient's nose length and width first and thus helps to select the correct
ventilation mask in each case. The ClassicStar NIV nasal mask is available as
a non-ventilated mask for use with respiratory equipment with an active
exhaust system. A ventilated version for respiratory equipment with
continuous positive airway pressure, without an active exhaust expiration
system is also available.
