1. Breathing Pattern and Lung Mechanics during Assisted Ventilation Response of Slowly Adapting Pulmonary Stretch Receptors and Effects on Phrenic Nerve Activity in Cats with Normal and Surfactant Depleted Lungs
Abstract : Different modes of assisted ventilation were investigated in cats before and after lung lavage and after instillation of surfactant. The activity of single units of slowly adapting pulmonary stretch receptors (PSRs) in the vagal nerve and the integrated phrenic nerve activity were recorded. READ MORE

2. Optimizing mechanical ventilation in extremely preterm infants
Abstract : Extremely low gestational age newborns (ELGANs) i.e. infants born before 28 weeks of gestational age (GA), require respiratory support during their hospital stay, and a majority needs mechanical ventilation (MV) at some time point. READ MORE

3. Regulation of Breathing under Different Pulmonary Conditions
Abstract : The breathing pattern of preterm infants is immature and is associated with a variety of reflexes. In a patient on the ventilator these reflexes interfere with spontaneous breathing. A better understanding of the immature control of breathing could lead to further improvements in ventilatory techniques. READ MORE

4. Clinical and experimental studies on the diaphragm during physiological and pathophysio-logical conditions
Abstract : The diaphragm is the most important respiratory muscle. It separates the thorax from the abdomen and it is innervated by phrenic nerve. READ MORE

5. On the interaction between a neuromuscular blocking agent and regulation of breathing during hypoxia
Abstract : It was previously generally agreed that a mechanical train-of-four (TOF) ratio >0.70 represented an adequate recovery of respiratory function after neuromuscular blockade. Normal respiratory parameters at this level of recovery and during air breathing support this view. READ MORE
