OBJECTIVE: Boussignac continuous positive airway pressure (BCPAP) delivered by face mask is useful
for patients with acute cardiogenic pulmonary edema (ACPE). Although BCPAP is medically effective,
we observed that not all suitable patients received it. In this descriptive, prospective, cohort study, we
explored the experiences and attitudes of both patients and staff with BCPAP.
METHODS: Patients were interviewed 12 to 48 hours after treatment with BCPAP. Nurses on the coronary
care unit were interviewed on their knowledge, skills, experiences, and opinions concerning BCPAP.
RESULTS: Of 117 patients with ACPE, 87 patients (74%) received BCPAP treatment. It was decided not
to administer BCPAP in 30 patients with ACPE (26%). Patients who received BCPAP found that the
reduction of dyspnea outweighed any discomfort. Barriers for the use of BCPAP were not related to
nurses’ skills but to the following: the nurses’ belief that BCPAP created major discomfort, the lack of
guidelines, the ultimate improvement of oxygenation without BCPAP, and the more labor-intensive
treatment.
CONCLUSION: Overestimation of patient discomfort by nurses and system-related factors impeded the
use of BCPAP for all patients with ACPE. (Heart Lung® 2008;37:449 – 454.)
A
cute cardiogenic pulmonary edema (ACPE)
caused by chronic heart failure is a common
medical emergency that frequently manifests
itself with sudden dyspnea and hypoxemia. When
treatment with oxygen, opiates, diuretics, and vaso-
dilators do not result in sufficient improvement,
additional ventilatory support may be required.

Traditionally, ventilatory support has been effected
via endotracheal intubation and mechanical venti-
lation, an approach that usually requires admission
to the intensive care unit. Several randomized clin-
ical trials demonstrated a decrease in the rate of
intubation and hospital length of stay for patients
assigned to continuous positive airway pressure
(CPAP) compared with conventional therapy with
oxygen alone.

International heart failure guide-
lines mention that CPAP treatment is an effective
and accepted treatment option in these patients.

Coronary care units (CCUs) in The Netherlands are
usually not equipped for applying respiratory sup-
port with mechanical ventilators. Most nurses in the
CCU are not trained to ventilate patients and have
limited expertise and experience in the field of con-
ventional mask CPAP. Therefore, we introduced the
Boussignac continuous positive airway pressure
(BCPAP) system (Fig 1) in the CCU. The BCPAP
system is a simple disposable cylindric plastic de-
vice that requires only an O

source and a flow
meter to generate face mask CPAP. This easy-to-
handle system can be used outside of the intensive
