Respiratory Assistance

Mechanical ventilation has long been used to maintain ventilation in humans when the lungs are rendered incapable of oxygenation or when respiration is affected by central nervous system depression, but it has only recently been applied to similar cases in dogs and cats. Although manual ventilation is still the more common form of ventilation in dogs and cats, mechanical intermittent positive-pressure ventilation (IPPV) is a much more efficient and reliable means of maintaining the highest quality of respiratory assistance. With proper training, technicians can use IPPV to support compromised animals until they are capable of maintaining normal oxygen concentrations.

Abstract Aims To compare the effect of early nasal intermittent positive pressure ventilation (nIPPV) and nasal continuous positive airway pressure (nCPAP) in terms of the need for endotracheal ventilation in the treatment of respiratory distress syndrome (RDS) in preterm infants born between 24 and 32 gestational weeks. Methods This is a randomized, controlled, prospective, single-centered study. Forty-two infants were randomized to nIPPV and 42 comparable infants to nCPAP (birth weight 1356 ± 295 and 1359 ± 246 g and gestational age 29.2 ± 1.7 and 29.4 ± 1.5 weeks, respectively). Results The need for endotracheal intubation and invasive mechanical ventilation was significantly lower in the nIPPV group than the nCPAP group (11.9% and 40.5%, respectively, p < 0.05). There were no differences in the duration of total nasal respiratory support, duration of invasive mechanical ventilation, bronchopulmonary dysplasia or other early morbidities. Conclusion nIPPV compared with nCPAP reduced the need for endotracheal intubation and invasive mechanical ventilation in premature infants with RDS.

Objective: To evaluate the occurrence of postoperative sore throat after the use of LMA among patients undergoing surgery on intermittent positive pressure ventilation and those on spontaneous mode. Methods: hundred adult patients of ASA I or II status were included and divided into two equal groups. Group I patients were randomly assigned for positive pressure ventilation and group II patients for spontaneous breathing. Anaesthesia was administered with propofol, oxygen nitrous oxide and halothane. The LMA of appropriate size was placed.After completion of surgery, LMA was removed when the patient regained deglutition reflex. Patient was questioned postoperatively for variables of sore throat for three days. Results: In group I, 12% patients complained of mild sore throat in comparison to group II where 6% suffered from mild sore throat (p>0.05). There was no difference in the discomfort levels among males and females. Conclusion: Pharyngolaryngeal discomfort is less after use of LMA under spontaneous ve ntilation in comparison to controlled ventilation.

‘Lung Ventilation: Natural and Mechanical’ describes the processes of respiration and lung ventilation, focusing on those issues related directly to mechanical ventilation. The chapter starts by discussing the anatomy and physiology of respiration, and the involvement of the lungs and the entire respiratory system. It continues by introducing the three operating principles of mechanical ventilation. It then narrows its focus to intermittent positive pressure ventilation (IPPV), the operating principle of most modern critical care ventilators, explaining the pneumatic process of IPPV. The chapter ends by comparing natural and mechanical/artificial lung ventilation.

Medical Ventilator System Basics: A clinical guide—unlike books that focus on clinical applications, or that provide specifics about individual ventilator models, this is a practical guide about the equipment used for positive pressure mechanical ventilation. This book provides the information a clinician needs every day: how to assemble a ventilator system, how to determine appropriate ventilator settings, how to make sense of monitored data, how to respond to alarms, and how to troubleshoot ventilation problems. The book applies to all ventilators based on the intermittent positive pressure ventilation (IPPV) operating principle. In a systematic and comprehensive way, the book steps the user through the ventilator system, starting with its pneumatic principles to an explanation of the anatomy and physiology of respiration. It describes the system components, including the ventilator, breathing circuit, humidifier, and nebulizer. The book then introduces ventilation modes, starting with an explanation of the building blocks of breath variables and breath types. It describes the major ventilator functions, including control parameters, monitoring, and alarms. Along the way the book provides much practical troubleshooting information. Clearly written and generously illustrated, the book is a handy reference for anyone involved with mechanical ventilation, clinicians and non-clinicians alike. It is suitable as a teaching aid for respiratory therapy education and as a practical handbook in clinical practice.

Intermittent abdominal pressure ventilation is a positive pressure ventilation technique that works with abdominal compressions. It has been known since 1938; however, for many years, it was out of production. In recent years, a new device has been produced that has captured the attention to this old respiratory support technique. We considered eight patients with respiratory failure secondary to a neuromuscular disease (congenital myopathy, Duchenne dystrophy, and amyotrophic lateral sclerosis) intolerant to daytime noninvasive ventilation (NIV). IAPV was proposed as an alternative to NIV. We performed baseline and post-IAPV respiratory function assessment. All patients, two years later, are still using intermittent abdominal ventilation. Intermittent positive abdominal mechanical ventilation can be a valid alternative to noninvasive mechanical ventilation with a nasal or face mask. It improves gas exchange, symptoms, and quality of life, decreases the incidence of pneumonia, and can avert the need for intubation and tracheotomy.
