The district medical officer's role during the pandemic - a qualitative study.

Background: We studied the district medical officers' role during the pandemic with a view to enhancing our knowledge of their role in municipal crisis management.

Material And Method: Fourteen semi-structured interviews were conducted with key participants in crisis management in five local authorities, in the fields of medicine, policy and administration. The data were subjected to empirical qualitative analysis inspired by stepwise deductive-bottom-up methodology.

Selective positive end-expiratory pressure and right ventricular function in dogs.

Differential ventilation with selective positive end-expiratory pressure (PEEP) has been shown to reduce cardiac output less than general PEEP. In previous studies we have demonstrated that during selective PEEP left ventricular preload is better maintained than during general PEEP. The present study was designed to determine whether the different haemodynamic responses to selective and general PEEP also might be due to different effects on RV preload.

Selective positive end-expiratory pressure and intracardiac dimensions in dogs.

Effects of differential ventilation with general vs. selective right (R) and left (L) positive end-expiratory pressure (PEEP) on left (LV) and right ventricular (RV) end-diastolic dimensions were compared in seven pentobarbital-anesthetized dogs. All three modes of PEEP reduced LV cross-sectional area: general PEEP more than RPEEP and RPEEP more than LPEEP.
