This single-center observational study aims to assess the effects of continuous high-frequency oscillation (CHFO) and continuous positive expiratory pressure (CPEP) therapy on lung recruitment using electrical impedance tomography (EIT) in spontaneously breathing patients admitted to the intensive care unit.
Study Type
OBSERVATIONAL
Enrollment
26
During application of CPEP and CHFO, EIT is monitored.
UO Clinica Anestesiologica e Terapia Intensiva, IRCCS Ospedale Policlinico San Martino
Genova, GE, Italy
To assess changes in systemic oxygenation
Arterial partial pressure of oxygen (PaO2, mmHg) and PaO2/FiO2 ratio (mmHg)
Time frame: Immediately before starting treatment (PEP or CHFO), immediately after the end of treatment, at 30 minutes after the end of treatment and at 60 minutes after the end of treatment
Changes in lung recruitment using EIT
Absolute reduction in the percentage (%) of lung volume collapse assessed with the electrical impedance tomography (EIT)
Time frame: Immediately before starting treatment (PEP or CHFO), immediately after the end of treatment, at 30 minutes after the end of treatment and at 60 minutes after the end of treatment
Mean arterial pressure, mmHg
Heart rate as measured by continuous pressure monitoring
Time frame: Immediately before starting treatment (PEP or CHFO), immediately after the end of treatment, at 30 minutes after the end of treatment and at 60 minutes after the end of treatment
Heart rate min-1
Heart rate as measured by continuous electrocardiogram monitoring
Time frame: Immediately before starting treatment (PEP or CHFO), immediately after the end of treatment, at 30 minutes after the end of treatment and at 60 minutes after the end of treatment
