Obesity increases the work of breathing by greater body mass with its increased oxygen demand, impaired diaphragmatic mobility, upper airway obstruction, and oxygen desaturation which result in an inadequacy of oxygen demand and supply.

  • How Obesity Is Treated.

  • Obesity is a systemic process in which multiple organ systems are involved, among which the cardiovascular system, respiratory system and metabolic system seem to be affected mostly.

If OHS relates to a problem with breathing, can oxygen be used to treat it? When carbon dioxide cannot be properly removed, its levels increase and make the blood more acidic. It is a disease entity distinct from simple obesity and obstructive sleep apnea. Hypoventilation was corrected, with consequent improvements in alveolar ventilation. Proceedings of the American Thoracic Society; 5: 2, Without treatment it can lead to serious and even life-threatening health problems. Evidence suggests that volume targeting can improve the control of nocturnal hypoventilation and result in a significant decrease in transcutaneous carbon dioxide PtcCO2a method of non-invasive monitoring carbon dioxide via a probe placed on the skin, with the effect of normalising PtcCO2 during sleep.

Definitions of Obesity Hypoventilation Syndrome

OHS is characterized hypovenfilation prolonged attacks of sustained hypoxemia during sleep, in addition to daytime hypoxemia. AVAPS is a hybrid of these two modes and aims to delivery a guaranteed tidal volume Windisch et al, Chronic steady state hypercapnia establishes as a result of the failure of compensatory ventilatory mechanisms.

Aside from being a health concern patnophysiology itself, obesity can result in other serious health conditions. Management of Obesity Hypoventilation Syndrome The first step in successful management starts with making the diagnosis of OHS and referring the patient for polysomnography with titration study. Therefore, in contrast to animals, leptin cannot sufficiently increase ventilation in man to avoid hypercapnia. A prospective two centre study. However, when complications arise, there should be a high index of suspicion and pre- planned diagnostic and therapeutic approaches. Obesity is associated with multiple medical complications.

Affected subjects require the input from internists and endocrinologists pathophysiloogy their diabetes mellitus, hypertension, hyperlipidemia, heart failure and hypothyroidism therapy; a dietician for weight reduction planning; a respirologist for respiratory failure management; and a surgeon for potential bariatric surgery when needed. Association between hormone replacement therapy and subsequent arterial and venous vascular events: A meta-analysis. Although treatment modalities target different aspects of the underlying pathophysiology, the goal is normalization of arterial carbon dioxide, reduction of oxyhemoglobin desaturation, and improvement in symptoms.

Tankersley CG et al Leptin attenuates respiratory complications associated with the obese phenotype. Ultimately, the purpose of any treatment in obesity hypoventilation syndrome is to correct the underlying problems that contribute to the disease. The mainstay of treatment in OHS is to provide breathing support, often through the use of continuous positive airway pressure CPAP or bilevel. In people who are obese, adipose tissue mass in the abdominal and intrathoracic regions hinders the ability of the lungs to fully inflate, mainly by restricting the normal movement of the diaphragm during breathing.

Due to the simultaneous occurrence of OSA in the majority of patients, symptoms like snoring, witnessed hypovventilation and poor sleep quality with early morning headache and reduced performance are reported. Their initial laboratory values will show elevated serum bicarbonate level, which is typically seen as a result of metabolic compensation of respiratory acidosis, which points toward the chronic nature of hypercapnia. In case of pulmonary hypertension and right-sided heart failure, patients might report symptoms like exertional dyspnea and lower limb edema. Arch Otolaryngol Head Neck Surg. Generally, it is thought that obese subjects developing daytime hypoventilation show some form of SDB; they have reduced sensitivity to rising levels of PaCO 2 and tend to have leptin resistance in the setting of high serum leptin level.

Despite its major impact on health, this disorder is under-recognized and hypoventilxtion. Therefore, in contrast to animals, leptin cannot sufficiently increase ventilation in man to avoid hypercapnia. Sleep is a state of reversible unresponsiveness to the environment, in which the brain is relatively more responsive to internal than to external stimuli; and contrary to common beliefs, it is an active physiological central nervous phenomenon with cyclical changes alternating between nonrapid eye movement sleep NREM and rapid eye movement sleep REM [ 1 ]; and based on electrophysiological studies, NREM sleep is further subdivided into 4 stages I-IV according to recorded cortical electrical potentials.

Continuing Education Activity The prevalence of obesity in the United States has doubled since and currently, 35 percent of this country's population suffers from obesity. Through respiratory support, patients may have a better quality of sleep, reduced hypercapnia and hypoxia, and improved activities of daily living. Having said that, one can conclude that sleep is a complex physiological process and that normal sleep architecture can be lost via several mechanisms acting at different levels of the respiratory system. First of all, there is loss of the wakefulness drive to breathe; second, there are changes in the chemical stimuli driving breathing PaCO 2PaO 2 associated with modification of central control of breathing; and lastly, there is an increase in respiratory arousal threshold. However, most patients with OHS most common initial presentation is in a hospital setting after presenting with an acute exacerbation where an ABG along with a basic metabolic panel can be done.
