BACKGROUND: We evaluated if incentive spirometry volume (ISV) and peak expiratory flow rate (PEFR) could predict acute respiratory failure (ARF) in patients with rib fractures. METHODS: Normotensive, co-operative patients were enrolled prospectively. ISV and PEFR were measured on admission, at 24 h and at 48 h by taking the best of three readings each time. The primary outcome, ARF, was defined as requiring invasive or noninvasive positive pressure ventilation...

Instruction and Objectives. Noninvasive positive pressure ventilation (NPPV) alleviates sleep-disordered breathing (SDB) and it may improve cardiac function in SDB patients. Because large randomized controlled trials directly evaluating the impact of NPPV on cardiac function are lacking, we conducted a meta-analysis of published data on effectiveness of NPPV in improving cardiac function in patients with chronic heart failure regardless of SDB presence. Methods. Controlled trials were identified in PubMed, OVID, and EMBASE databases...

BACKGROUND: Noninvasive ventilation (NIV) titration may be difficult when dynamic airway obstruction episodes persist, even with high expiratory positive airway pressure (EPAP). We aimed to determine the usefulness of videolaryngoscopy during NIV for identifying mechanisms and sites of obstruction and for providing a guide for their resolution in difficult-to-titrate subjects. METHODS: When obstructions during NIV were present in the built-in software, EPAP was raised to 12cm H2O...

REVIEW

The incidence of bronchopulmonary dysplasia (BPD) has not decreased over the last decade. The most important way to decrease BPD is by weaning the patient from the ventilator as soon as possible in order to reduce ventilator-induced lung injury that underlies BPD, and by using a noninvasive ventilator (NIV). Use of a heated, humidified, high flow nasal cannula (HHHFNC), which is the most recently introduced NIV mode for respiratory support in preterm infants, is rapidly increasing in many neonatal intensive care units due to the technical ease of use without sealing, and the attending physician's preference compared to other NIV modes...

Morbidly obese, critically ill patients are prone to develop hypoxemic respiratory failure and ventilator dependency. The best method for recruiting the lungs of these patients and keeping alveoli open without causing injury remains unclear. We present the case of a 31-year-old patient with severe refractory hypoxemia reversed by lung recruitment maneuvers and subsequent application of positive end-expiratory pressure (PEEP) at a level determined by a decremental PEEP trial. The patient was extubated at a high PEEP level of 22 cm H2O followed by noninvasive ventilatory support after extubation...

BACKGROUND: Noninvasive ventilation (NIV) is a common technique to manage patients with acute respiratory failure in the intensive care unit. However, use of NIV in general wards is less well described. The authors' aim was to demonstrate efficacy of NIV, applied in a cardiac surgery ward, in improving oxygenation in patients who developed hypoxemic acute respiratory failure after being discharged from the intensive care unit. DESIGN: Randomized, open-label trial...

Current devices for providing noninvasive respiratory support contain sensors and built-in intelligence for automatically modifying ventilation according to the patient's needs. These devices, including automatic continuous positive airway pressure devices and noninvasive ventilators, are technologically complex and offer a considerable number of different modes of ventilation and setting options, the details of which are sometimes difficult to capture by the user. Therefore, better predicting and interpreting the actual performance of these ventilation devices in clinical application requires understanding their functioning principles and assessing their performance under well controlled bench test conditions with simulated patients...

Intact cerebral blood flow (CBF) is essential for cerebral metabolism and function, whereas hypoperfusion in relation to hypovolemia and hypocapnia can lead to severe cerebral damage. This study was designed to assess internal carotid artery blood flow (ICA-BF) during simulated hypovolemia and noninvasive positive pressure ventilation (PPV) in young healthy humans. Beat-by-beat blood velocity (ICA and aorta) were measured by Doppler ultrasound during normovolemia and simulated hypovolemia (lower body negative pressure), with or without PPV in 15 awake subjects...

BACKGROUND: Noninvasive positive pressure ventilation (NPPV) provides ventilation without tracheal intubation. Facial pressure injury is a recognized complication of this technique, making the prevention of facial pressure injuries an important issue for NPPV patients. PURPOSE: The present study compared the effects of foam dressing and hydrocolloid dressing in preventing facial pressure injuries in NPPV patients. METHODS: A randomized clinical trial was used to evaluate participants that were referred from the intensive care unit of a medical center in eastern Taiwan...

Some patients are agitated and unable to tolerate conventional preoxygenation methods, including face mask oxygen or noninvasive positive-pressure ventilation. Sedation with ketamine for preoxygenation, also known as delayed sequence intubation, is a technique that can be used to achieve preoxygenation in this patient population. No complications of delayed sequence intubation have previously been reported. A 60-year-old woman presented with acute hypoxic respiratory failure. Despite application of high-flow oxygen (60 L/min) with a nonrebreather face mask, her oxygen saturation remained at 93%...

Dead space fraction (V d/V t) measurement performed using volumetric capnography requires arterial blood gas (ABG) sampling to estimate the partial pressure of carbon dioxide (PaCO2). In recent years, transcutaneous capnography (PtcCO2) has emerged as a noninvasive method of estimating PaCO2. We hypothesized that PtcCO2 can be used as a substitute for PaCO2 in the calculation of V d/V t. In this prospective pilot comparison study, 30 consecutive postcardiac surgery mechanically ventilated patients had V d/V t calculated separately using volumetric capnography by substituting PtcCO2 for PaCO2...

BACKGROUND: Compared to pneumatically controlled pressure support (PSP), neurally adjusted ventilatory assist (NAVA) was proved to improve patient-ventilator interactions, while not affecting comfort, diaphragm electrical activity (EAdi), and arterial blood gases (ABGs). This study compares neurally controlled pressure support (PSN) with PSP and NAVA, delivered through two different helmets, in hypoxemic patients receiving noninvasive ventilation for prevention of extubation failure. METHODS: Fifteen patients underwent three (PSP, NAVA, and PSN) 30-min trials in random order with both helmets...

We describe an 11-year-old boy with nemaline myopathy who developed tension pneumothorax while undergoing noninvasive positive-pressure ventilation (NIPPV). The patient developed a persistent air leak after pleurodesis with minocycline hydrochloride and lowering of the NIPPV inspiratory pressure. He required additional respiratory support without the high airway pressures that may aggravate pneumothorax. We provided adequate respiratory support without increasing the positive airway pressure using biphasic cuirass ventilation (BCV), which moved the patient's chest wall by negative pressure...
