Manual lung hyperinflation (MHI) can enhance secretion clearance, improve total lung/thorax compliance and assist in the resolution of acute atelectasis. To enhance secretion clearance in the intubated patient, the evidence highlights the need to maximize expiratory flow. Chronic pulmonary diseases such as chronic obstructive pulmonary disease (COPD) have often been cited as potential precautions and/or contra-indications to the use of manual lung hyperinflation (MHI). ⋯ MHI may also increase right ventricular after load through raised intrathoracic pressures with lung hyperinflation, and may therefore impair right ventricular function in patients with evidence of cor pulmonale. There is the potential for beneficial effects from MHI in the intubated COPD patient group (i.e., secretion clearance), but further research is required, especially on the effect of MHI on inspiratory and expiratory flow rate profiles in this patient group. The more controlled delivery of lung hyperinflation through the use of the mechanical ventilator may be a more optimal means of providing lung hyperinflation and should be further investigated.

Many deaths are now preceded by an end of life decision, particularly in the intensive care unit (ICU), but such practices vary considerably between countries, ICUs and individuals, depending on many factors including cultural and religious background, family and peer pressure and local practice. ⋯ Drawing data from several national and international studies, we then summarize the current situation across Europe regarding such practices before making some suggestions as to how we could facilitate the often difficult decision making process by improved communication between staff, patient and relatives.
