Obesity hypoventilation syndrome (also known as Pickwickian syndrome) is a condition in which severely overweight people fail to breathe rapidly enough or deeply enough, resulting in low blood oxygen levels and high blood carbon dioxide (CO2) levels. Many people with this condition also frequently stop breathing altogether for short periods of time during sleep (obstructive sleep apnea), resulting in many partial awakenings during the night, which leads to continual sleepiness during the day. The disease puts strain on the heart, which eventually may lead to the symptoms such as heart failure, leg swelling and various other related symptoms. The most effective treatment is weight loss, but it is often possible to relieve the symptoms by nocturnal ventilation with positive airway pressure (CPAP) or related methods. Obesity hypoventilation syndrome is defined as the combination of obesity (body mass index above 30 kg/m2), hypoxemia (falling oxygen levels in blood) during sleep, and hypercapnia ...
Obesity Hypoventilation (OHS) is also called pickwick syndrome. The classic features of obesity hypoventilation syndrome (OHS) are obesity and daytime hypercapnia.
The obesity hypoventilation syndrome (OHS) is characterised by obesity and hypercapnia while awake in the absence of an alternative neuromuscular, mechanical, or metabolic explanation for hypoventilation. Most patients with OHS suffer from OSA and in many (but not all) cases treatment of OSA with NCPAP restores daytime eucapnia.31,32 In some patients OHS cannot be explained on the basis of OSA,33 and daytime hypercapnia appears to result from inadequate physiological compensation for the development of obesity alone. This condition remains an enigma. Why do certain obese individuals hypoventilate during wakefulness while others with similar or greater levels of obesity do not? Could leptin be the key to understanding this conundrum?. The paper by Phipps and colleagues34 in this issue of Thorax contributes an interesting additional piece of information. The authors discovered that the mean serum leptin level was twice as high in a group of 12 hypercapnic obese humans as in a group of 44 eucapnic ...
The effects of obesity are multifaceted and lead to poor quality of life, increased risk of cardiovascular disease, stroke, and death. Obesity hypoventilation syndrome (OHS) is a widely misunderstood and under diagnosed disease process, which carries specific diagnostic criteria. The purpose of this work is to: (1) provide practitioners with a better understanding of OHS and how it differs from other obesity related breathing disorders (such as Obstructive Sleep Apnea, OSA), (2) provide diagnostic criteria of OHS, (3) provide work up recommendations, and (4) provide current recommended treatment. Data Sources: An electronic search of the literature was conducted to identify studies from 2008 to 2014 in the following databases: CINAHL, National Library of Medicine PubMed®/MEDLINE®, EBSCO, SciVerse®, Springer Link®, and the Cochrane library. Conclusions: The effects of obesity are multifaceted and lead to poor quality of life, increased risk of cardiovascular disease, stroke, and death. Obese

This study found that body mass index and serum bicarbonate, were two independent predictors for OHS among OSA patients (Table 2). This is in contrast to a previous study in the U.S., in which AHI was not found to be a significant factor for OHS (Table 3) [9]. Two other studies conducted in Turkey, also confirmed that serum bicarbonate was an independent predictor for OHS [10,11]. No previous study has evaluated if body mass index is a predictor for OHS, because obesity is a diagnostic criteria for the condition.. Although BMI criterion for OHS is 30 kg/m2, a report in Japan found that average BMI of OHS patients in the Japanese population was 37 [5]. This study also found that median BMI of OHS patients was also more than 30 kg/m2 (48.9 kg/m2) as shown in Table 1. However, the appropriate BMI cutoff point may not be 30 kg/m2 in this study. There were 8% of Thai OSA patients with OHS, who may not be diagnosed with BMI of 30 kg/m2 (Table 3). Findings may imply that Thai OSA patients could develop ...
Clinically important differences between the two concentrations of oxygen were observed in the present study, that is, hyperoxia induced by FiO2 0.28 caused minimal changes in pH or VE, while FiO2 0.50 caused hypoventilation and acidaemia. Furthermore, compared with responses to FiO2 0.50 in our OHS participants, even more marked changes in PCO2 and VE occurred during 100% oxygen in obesity-associated hypercapnia.7 The mechanisms by which hyperoxia induces hypoventilation in OHS remain unclear. However, these findings suggest that a greater degree of respiratory depression occurs with higher oxygen concentrations. Therefore, in stable OHS, hyperoxia caused by breathing FiO2 0.28 may be less harmful than FiO2 0.50 or 1.0.. Substantial inter-individual variability in ΔPavCO2 during hyperoxia was evident among the OHS group; as has been reported in obesity-associated hypercapnia7 and COPD.16 Therefore it would be clinically useful to identify features that may predict adverse responses to ...
• Obese patients suffer disorders of respiratory control.• Both obstructive sleep apnoea and the obesity hypoventilation syndrome are under-diagnosed.• Both syndromes have important implications for the perioperative course.• The obesity hypoventilation syndrome is characterised by reduced central respiratory drive and an elevated carbon dioxide tension while awake.• Obstructive sleep apnoea is characterised by nocturnal airway obstruction and desaturation.• Both syndromes are associated with cardiovascular complications and right heart failure.• Weight loss is an effective therapeutic strategy for both syndromes.• CPAP is effective in mitigating the effects of obstructive sleep apnoea.

1) Pickwick Papers: Charles Dickens played an important role in the field of sleep medicine. (Kryger M. Charles Dickens: impact on medicine and society. J Clin Sleep Med 2012;8(3):333-338.). First description of the sleep apnea syndrome was made by Charles Dickens in the Pickwick Papers in 1836. Almost 140 years after Pickwick Papers was published, doctors understood what he was describing. In 1956, Burwell et al introduced the term Pickwickian syndrome for obese patients with sleep apnea syndrome. It was later known as the obesity hypoventilation syndrome.. Obesity-hypoventilation syndrome (Pickwickian syndrome) consists of obesity ; sleep breathing disorder episodes of excessive daytime sleepiness or prolonged nighttime sleep ; chronic hypercapnia during wakefulness in the absence of other known causes of hypercapnia ; alveolar hypoventilation and right ventricular failure in serious cases.. Charles Dickens describes messenger boy Joe, in The Pickwick Papers as the wonderfully fat boy who is ...
Obesity hypoventilation syndrome. A 61-year-old woman with a history of polyarteritis nodosa, mononeuritis multiplex involving the lower extremities, and severe sleep apnea returns in followup following an overnight sleep study.
The increasing prevalence of obesity is alarming. The World Health Organization estimates that by 2015, ∼10% of the global population will be obese [28]. Obesity hypoventilation syndrome (OHS) is defined by a body mass index (BMI) ,30 kg·m−2 and chronic alveolar hypoventilation leading to daytime hypercapnia (arterial carbon dioxide tension (PaCO2) ,6 kPa), after exclusion of all other obstructive or restrictive diseases, chest wall disorders (CWDs) and neuromuscular diseases (NMDs) [29]. In developed nations, approximately one-third of patients with a BMI ≥35 kg·m−2 have chronic respiratory failure [30]. AHRF in obese patients is an increasingly common cause of hospitalisation and admission to ICUs. There is a paucity of data regarding the use of NIV in of AHRF in obese patients.. Rabec et al. [31] showed that AHRF in obese patients can be treated with NIV, with an improvement in PaCO2, and in the majority of cases (39 out of 41, 95%), ETI was avoided. Duarte et al. [32] reported ...

We thank Dr Esquinas and Dr. Petroianni for their interest in our study.[1] All the patients were included at the time of diagnosis, and therefore none of them had previously received oxygen therapy or positive airway pressure. Given that respiratory failure was a newly diagnosed medical condition, the previous duration of hypoxaemia is merely speculative.. We totally agree that obesity hypoventilation syndrome (OHS) is a heterogeneous entity with a wide range of severities, and that respiratory failure and haemodynamic impairment have a multifactorial nature. Several mechanisms appear able to contribute to respiratory insufficiency in OHS. These include respiratory muscle dysfunction, increased CO2 production, impaired respiratory system mechanics, altered respiratory drive and obstructive apnoeas during sleep. It is likely that the weight of each mechanism may vary from one patient to another. We have found evidence of this heterogeneity in a previous study, which uncovered that OHS patients ...
A 50-year-old African woman was referred to our sleep center for severe obstructive sleep apnea syndrome and obesity hypoventilation syndrome. Because she had alveolar hypoventilation and had failed previous obstructive sleep apnea syndrome therapy, noninvasive positive pressure ventilation was started. In May 2015, she had a normal residual apnea/hypopnea index calculated by the ventilator software with no hypoventilation. Six months later, severe hypoxemia without hypercapnia was noted. Contrast transthoracic echocardiography showed right-to-left shunt through a patent foramen ovale. This finding prompted a decrease in expiratory and inspiratory positive airway pressures, after which the ventilator software recorded a normal residual apnea/hypopnea index and the blood gas values improved.. CONCLUSION ...
The Pickwickian syndrome, also known as obesity hypoventilation syndrome, is the combination of severe obesity, suffering from obstructive sleep apnea causing hypoxia and hypercapnia resulting in marked daytime somnolence. Although it is an eponym, it is not named after the doctor who first described it (as commonly happens) but after a literary character by Charles Dickens.

Obesity hypoventilation syndrome (OHS) is a breathing problem. It affects some children who are obese. Poor breathing causes too much carbon dioxide and too little oxygen in the blood. This is a rare but life-threatening issue. Your child will need treatment right away.. When your child breathes, fresh air (oxygen) enters tiny sacs in his or her lungs. Tiny blood vessels run through the walls of these air sacs. When your child breathes in, oxygen moves from inside these sacs into the blood vessels. Carbon dioxide moves the other way, from the blood to the air sacs. So when your child breathes out, that air is low in oxygen and high in carbon dioxide. This process is called gas exchange.. Proper gas exchange is very important for human life. Every cell in your childs body needs oxygen to live. Carbon dioxide is a waste product that needs to be removed from the body. Children with OHS may not breathe as often and as deeply as they need to. This stops proper gas exchange. This causes carbon ...

After completion of surgery, the patient is transferred to the post anesthesia care unit and closely monitored. When the patient is judged to have recovered from the anesthesia, he/she is either transferred to a surgical ward elsewhere in the hospital or discharged home. During the post-operative period, the patients general function is assessed, the outcome of the procedure is assessed, and the surgical site is checked for signs of infection. There are several risk factors associated with postoperative complications, such as immune deficiency and obesity. Obesity has long been considered a risk factor for adverse post-surgical outcomes. It has been linked to many disorders such as obesity hypoventilation syndrome, atelectasis and pulmonary embolism, adverse cardiovascular effects, and wound healing complications.[11] If removable skin closures are used, they are removed after 7 to 10 days post-operatively, or after healing of the incision is well under way. It is not uncommon for surgical ...

The investigators hypothesized that increasing non intentional leaks could increase work of breathing and could lead to patient/non-invasive ventilation (NIV) asynchrony.. The main objective is to compare ventilatory pattern (work of breathing, flow, pressure) under NIV with and without non-intentional leaks in 10 awakened healthy subjects and 10 awakened and asleep obese hypoventilation syndrome (OHS) patients.. Methods: While the subjects will be under NIV, several levels of leaks will be simulated in a random order with an automatically opening valve. Breathing pattern (work of breathing,flow, pressure, thorax and abdominal movements) will be recorded by Polygraphy. Healthy subjects will be recorded only during awakened state. OHS patients will be recorded both during awake and sleep sates.. Analysis: A repeated measures analysis of variance (ANOVA) will compare work of breathing according to the different levels of leaks. ...

Hurtig debut fedme med hypothalamus dysfunktion, hypoventilation og autonome dysregulering (ROHHAD) er en sjælden lidelse med abnormiteter i vejrtrækning (hypoventilation), det endokrine system, og det autonome nervesystem (ANS). ANS er en del af nervesystemet, der styrer de ufrivillige kropsfunktioner. Derfor virker det "automatisk" at styre vejrtrækning, hjertebanken, fordøjelsen, blandt mange andre ting. ROHHAD blev første gang beskrevet i 1965 og siden da kun 75 børn er blevet rapporteret i litteraturen med denne lidelse. På grund af den høje forekomst af kardiorespiratorisk stop, tidlig diagnosticering og behandling af symptomer forbundet med ROHHAD er afgørende..

The purpose of this study was to compare the impact of NM with FFM use on sleep quality and gas exchange in subjects using NIV. In addition, the authors wished to ascertain subjective responses regarding comfort and leak. The data shows that the FFM used was equally effective as a NM in maintaining nocturnal gas exchange and preventing sleep disordered breathing in patients with known nocturnal hypoventilation syndromes, without the need to alter pressure settings. During the night the FFM was used, sleep efficiency was reduced, although the percentage of REM sleep time increased. No differences in arousal indices between the two nights were observed. Notably, 14 of the 16 subjects required the use of a chinstrap to minimise oral leak. Subjectively, patients felt the NM was slightly more comfortable to use, with fewer leaks compared with using the FFM.. Traditionally, NMs have been the primary means of providing long-term nocturnal ventilatory support for patients with chronic respiratory ...

We hypothesize that capnography could detect hypoventilation during induction of bronchoscopic sedation and starting bronchoscopy following hypoventilation, may decrease hypoxemia. Patients were randomized to: starting bronchoscopy when hypoventilation (hypopnea, two successive breaths of at least 50% reduction of the peak wave compared to baseline or apnea, no wave for 10 seconds) (Study group, n = 55), or when the Observer Assessment of Alertness and Sedation scale (OAAS) was less than 4 (Control group, n = 59). Propofol infusion was titrated to maintain stable vital signs and sedative levels. The hypoventilation during induction in the control group and the sedative outcome were recorded. The patient characteristics and procedures performed were similar. Hypoventilation was observed in 74.6% of the patients before achieving OAAS < 4 in the control group. Apnea occurred more than hypopnea (p < 0.0001). Hypoventilation preceded OAAS < 4 by 96.5 ± 88.1 seconds. In the study group, the induction ...
