BACKGROUND: Among a group of therapies collectively known as energy psychology (EP), emotional freedom techniques (EFT) is the most widely practiced. Clinical EFT is an evidence-based practice combining elements of cognitive and exposure therapies with the manual stimulation of acupuncture points (acupoints). Lacking is a recent quantitative meta-analysis that enhances understanding of the variability and clinical significance of outcomes after clinical EFT treatment in reducing depression...

Patient-ventilator synchrony has been the focus of attention in the field of mechanical ventilation for quite some time now. Toward that end, the modern ventilators are equipped with very sensitive pneumatic triggering mechanisms, which allow for minimal wasting of patient effort. The increasingly sensitive pneumatic triggers have the potential to cause autotriggering, where stimuli other than neural signals (eg, cardiac oscillations) can trigger the mechanical breath. Although autotriggering has been well documented in brain-dead patients, its existence is difficult to prove in patients who have the ability to trigger breath through neural diaphragmatic activity...

Trans-diaphragmatic intercostal hernia is a rare entity. Patient with multiple medical comorbidities, including obstructive sleep apnoea, presents with shortness of breath, leg oedema and a bulging swelling through the right chest wall. CT shows partial herniation of the right lung and liver through intercostal space and an echocardiogram reveals right heart failure. He was treated initially with continuous positive airway pressure with poor response and subsequently treated with adaptive servo ventilation with much better symptomatic relief and treatment tolerance...

The term amyotrophic lateral sclerosis (ALS) comprises a group of motor neuron diseases which are characterized by rapid disease progression and poor prognosis which is mostly due to severe respiratory muscle weakness and its sequelae. Since causative treatment options are limited it is crucial to offer comprehensive symptomatic therapies to affect patients. Symptoms of respiratory muscle weakness, sleep-disordered breathing and, subsequently, chronic hypercapnic respiratory failure are known to severely affect health-related quality of life and social functioning of patients with ALS...

BACKGROUND: Predicting whether an obese critically ill patient can be successfully extubated may be specially challenging. Several weaning tests have been described but no physiological study has evaluated the weaning test that would best reflect the post-extubation inspiratory effort. METHODS: This was a physiological randomized crossover study in a medical and surgical single-center Intensive Care Unit, in patients with body mass index (BMI) >35 kg/m(2) who were mechanically ventilated for more than 24 h and underwent a weaning test...

PURPOSE: Contrary to what is commonly assumed, organs continue to move during breath-holding. We investigated the influence of lung volume on motion magnitude during breath-holding and changes in velocity over the duration of breath-holding. MATERIALS AND METHODS: Sixteen healthy subjects performed 60-second inhalation breath-holds in room-air, with lung volumes of ∼100% and ∼70% of the inspiratory capacity, and exhalation breath-holds, with lung volumes of ∼30% and ∼0% of the inspiratory capacity...

BACKGROUND: Rumination syndrome is a functional gastrointestinal disorder characterized by effortless and repetitive regurgitation of recently ingested food from the stomach to the oral cavity followed by either re-swallowing or spitting. Rumination is thought to occur due to a reversal of the esophagogastric pressure gradient. This is achieved by a coordinated abdominothoracic maneuver consisting of a thoracic suction, crural diaphragm relaxation and an increase in intragastric pressure...

The human ribcage expands and contracts during respiration as a result of the interaction between the morphology of the ribs, the costo-vertebral articulations and respiratory muscles. Variations in these factors are said to produce differences in the kinematics of the upper thorax and the lower thorax, but the extent and nature of any such differences and their functional implications have not yet been quantified. Applying geometric morphometrics we measured 402 three-dimensional (3D) landmarks and semilandmarks of 3D models built from computed tomographic scans of thoraces of 20 healthy adult subjects in maximal forced inspiration (FI) and expiration (FE)...

Neurological respiratory deficits are serious outcomes of West Nile virus (WNV) disease. WNV patients requiring intubation have a poor prognosis. We previously reported that WNV-infected rodents also appear to have respiratory deficits when assessed by whole-body plethysmography and diaphragmatic electromyography. The purpose of this study was to determine if the nature of the respiratory deficits in WNV-infected rodents is neurological and if deficits are due to a disorder of brainstem respiratory centers, cervical spinal cord (CSC) phrenic motor neuron (PMN) circuitry, or both...

Perioperative necessity of deep sedation is inevitably associated with diaphragmatic inactivation. This study investigated 1) the feasibility of a new phrenic nerve stimulation method allowing early diaphragmatic activation even in deep sedation and, 2) metabolic changes within the diaphragm during mechanical ventilation compared to artificial activity. 12 piglets were separated into 2 groups. One group was mechanically ventilated for 12 hrs (CMV) and in the second group both phrenic nerves were stimulated via pacer wires inserted near the phrenic nerves to mimic spontaneous breathing (STIM)...

BACKGROUND: Diaphragmatic dysfunction is often underdiagnosed and is among the risk factors for failed weaning. The purpose of this study was to determine the prevalence of diaphragmatic dysfunction diagnosed by B-mode ultrasonography and to determine whether prolonged weaning subjects with diaphragmatic dysfunction have increased duration of mechanical ventilation compared with those without diaphragmatic dysfunction. METHODS: This was a prospective observational study in mechanically ventilated subjects who failed ≥3 spontaneous breathing trials or required >7 d of weaning after the first spontaneous breathing trial...

BACKGROUND: The rapid shallow breathing index (RSBI), which is the ratio between respiratory rate (RR) and tidal volume (VT), is one of the most widely used indices to predict weaning outcome. Whereas the diaphragm plays a fundamental role in generating VT, in the case of diaphragmatic dysfunction the inspiratory accessory muscles may contribute. If this occurs during a weaning trial, delayed weaning failure is likely since the accessory muscles are more fatigable than the diaphragm. Hence, we hypothesised that the traditional RSBI could be implemented by substituting VT with the ultrasonographic evaluation of diaphragmatic displacement (DD)...

Background Phrenic nerve reconstruction has been evaluated as a method of restoring functional activity and may be an effective alternative to diaphragm plication. Longer follow-up and a larger cohort for analysis are necessary to confirm the efficacy of this procedure for diaphragmatic paralysis. Methods A total of 180 patients treated with phrenic nerve reconstruction for chronic diaphragmatic paralysis were followed for a median 2.7 years. Assessment parameters included: 36-Item Short Form Health Survey (SF-36) physical functioning survey, spirometry, chest fluoroscopy, electrodiagnostic evaluation, a five-item questionnaire to assess specific functional issues, and overall patient-reported outcome...

PURPOSE: To assess the ability of diaphragmatic ultrasound (US) to predict weaning failure in mechanically ventilated patients undergoing a first spontaneous breathing trial (SBT). METHODS: During a 4-month period, 67 consecutive patients eligible for a first SBT underwent US measurements of maximal diaphragmatic excursion (MDE) by a right anterior subcostal approach. Weaning failure was defined as either the failure of SBT or the need for resumption of ventilatory support for acute respiratory failure or death within 48h following successful extubation...

BACKGROUND: Wind instruments musicians are particularly prone to excessive respiratory efforts. Prolonged wind instruments performing may lead to changes in respiratory tracts and thus to respiratory muscles overload. It may result in decreasing lung tissue pliability and, as a consequence, in emphysema. Aim of the research has been to describe basic spirometric parameters for wind players and causes of potential changes. MATERIAL AND METHODS: Slow and forced spirometry with the use of Micro Lab Viasys (Micro Medical, Great Britain) was conducted on 31 wind musicians (group A)...

PURPOSE: Diaphragmatic dysfunction (DD) has a high incidence in critically ill patients and is an under-recognized cause of respiratory failure and prolonged weaning from mechanical ventilation. Among different methods to assess diaphragmatic function, diaphragm ultrasonography (DU) is noninvasive, rapid, and easy to perform at the bedside. We systematically reviewed the current literature assessing the usefulness and accuracy of DU in intensive care unit (ICU) patients. METHODS: Pubmed, Cochrane Database of Systematic Reviews, Embase, Scopus, and Google Scholar Databases were searched for pertinent studies...
