Physiological changes of pregnancy imposes higher risk of acute respiratory failure (ARF) with even a slight insult and remains an important cause of maternal and fetal morbidity and mortality. Although pregnant women have different respiratory physiology and different causes of ARF, guidelines specific to ventilatory settings, goals of oxygenation and weaning process could not be framed due to lack of large-scale randomized controlled trials. During the 2009 H1N1 pandemic, pregnant women had higher morbidity and mortality compared to nonpregnant women...

BACKGROUND: Adaptive servo-ventilation (ASV) therapy is a recent non-invasive positive pressure ventilation therapy that was developed for patients with heart failure (HF) refractory to optimal medical therapy. However, it is likely that ASV therapy at relatively higher pressure setting worsens some of the patients' prognosis compared with optimal medical therapy. Therefore, identification of optimal pressure settings of ASV therapy is warranted. CASE PRESENTATION: We present the case of a 42-year-old male with HF, which was caused by dilated cardiomyopathy, who was admitted to our institution for evaluating his eligibility for heart transplantation...

BACKGROUND: Nitric oxide (NO) is a major endogenous regulator of vascular tone. Inhaled nitric oxide (iNO) gas has been investigated as treatment for persistent pulmonary hypertension of the newborn. OBJECTIVES: To determine whether treatment of hypoxaemic term and near-term newborn infants with iNO improves oxygenation and reduces rate of death and use of extracorporeal membrane oxygenation (ECMO), or affects long-term neurodevelopmental outcomes. SEARCH METHODS: We used the standard search strategy of the Cochrane Neonatal Review Group to search the Cochrane Central Register of Controlled Trials (CENTRAL; 2016, Issue 1), MEDLINE via PubMed (1966 to January 2016), Embase (1980 to January 2016) and the Cumulative Index to Nursing and Allied Health Literature (CINAHL; 1982 to January 2016)...

BACKGROUND: Mid-frequency ventilation, a strategy of using conventional ventilators at high frequencies, may reduce lung injury but has had limited evaluation in neonates. Hence, a randomized crossover study was designed to assess the feasibility of using mid-frequency ventilation in preterm infants with respiratory distress syndrome. METHODS: Twelve preterm infants (≥500 g and ≥24 weeks gestational age) who were receiving pressure-limited conventional ventilation with frequencies ≤60 breaths/min for respiratory distress syndrome were randomized to periods of mid-frequency ventilation (conventional ventilation with the fastest frequency up to 150 breaths/min that gave complete inspiration and expiration) or conventional ventilation (frequency ≤60 breaths/min), each lasting 2 h using a crossover design...

: The purpose of this study was to examine the physiological characteristics of an elite centenarian cyclist who, at 101 years old, established the one-hour cycling record for individuals ≥ 100 years old (24.25 km) and to determine the physiological factors associated with his performance improvement two years later at 103 years old (26.92 km; +11%). Before each record, he performed an incremental test on a cycling ergometer. For two years, he trained 5,000 km a year with a polarized training that involved cycling 80% of mileage at "light" RPE ≤ 12 and 20% at "hard" RPE ≥ 15 at a cadence between 50 and 70 rpm...

BACKGROUND: Palliative care (PC) services are integral to the care of patients with advanced medical illnesses. Given the significant morbidity and mortality associated with cardiac arrest, we sought to measure the use and impact of PC in the care of patients treated with therapeutic hypothermia (TH). METHODS: We conducted a retrospective study of 317 consecutive patients undergoing TH after cardiac arrest. We compared intensive care unit (ICU) characteristics and clinical outcomes of subjects who received PC consultation (n=125) to those who did not (n=192)...

The most common technique in sound restoration of the middle ear is prosthetic surgery. Hypoventilation of the middle ear may cause adhesive otitis or atelectasis resulting in a higher risk of prosthetic extrusion rate and recurrence of the underlying cholesteatoma. We report long-term results using an island of tragal cartilage as an autologous PORP in selected patients with poor middle ear ventilation. Retrospective chart reviews were performed for procedures involving 52 patients between year 2000 and 2009...

We present the use of a low-resistance membrane oxygenator (Quadrox D, Maquet) in series with a pulsatile right ventricular assist device (Berlin Heart EXCOR, Berlin Heart) in a patient with biventricular support who required high-frequency oscillatory ventilation (HFOV), due to refractory acute respiratory distress syndrome associated with Cytomegalovirus pneumonia. The high mean airway pressure associated with the use of HFOV resulted in a significant negative impact on left ventricular assist device (LVAD) filling that led to a combined respiratory and metabolic acidosis and the need for vasopressor support...

Neuroblastoma (NB) is the most frequently diagnosed neoplasm during infancy and its incidence declines within the first 3-5 years of life. It can be rarely diagnosed in adolescents and young adults. Adolescents have advanced stage of disease, higher frequency of uncommon metastatic sites such as lungs, and worse outcomes. Herein, we describe an unusual case of NB in a 17-year-old adolescent presented with lung metastasis at diagnosis. The patient was diagnosed with stage IV NB. Thorax high-resolution computed tomography (HRCT) scan revealed irregular septal thickening with ground glass opacity consistent with pulmonary parenchymal metastases...

INTRODUCTION: An emergency surgical airway (ESA) is widely recommended for securing the airway in critically ill patients who cannot be intubated or ventilated. Little is known of the frequency, clinical circumstances, management methods, and outcomes of hospitalized critically ill patients in whom ESA is performed outside the emergency department or operating room environments. METHODS: We retrospectively reviewed all adult patients undergoing ESA in our intensive care units (ICUs) and other hospital units from 2008 to 2012 following activation of our difficult airway management team (DAMT)...

PURPOSE OF REVIEW: Severe respiratory failure due to the acute respiratory distress syndrome (ARDS) might require rescue therapy measures beyond even extended standard care to ensure adequate oxygenation and survival. This review provides a summary and assessment of treatment options that can be beneficial when the standard approach fails. RECENT FINDINGS: 'Life-threatening' conditions or refractory hypoxemia during mechanical ventilation are more a matter of personal rating than an objective diagnosis based on defined and/or unanimously agreed thresholds that would mandate the use of rescue therapies...

BACKGROUND: High-flow nasal cannula therapy (HFNC) is widely used for patients with acute respiratory failure. HFNC has a number of physiological effects. Although FIO2 is considered to be constant, because HFNC is an open system, FIO2 varies according to inspiratory flow, tidal volume (VT), and HFNC gas flow. We investigated the influence of HFNC gas flow and other respiratory parameters on FIO2 during HFNC. METHODS: We evaluated an HFNC system and, for comparison, a conventional oxygen therapy system...
