Does oxygen therapy reduce breathlessness? Although intractable breathlessness is the most common reason for prescribing home oxygen therapy for patients with chronic heart failure, evidence is mounting that supplemental oxygen does not reduce breathlessness. A large observational study of patients with breathlessness of varying aetiology concluded that oxygen therapy was of no benefit in the a...

BACKGROUND Obese hypoxemic patients have a high prevalence of sleep disordered breathing (SDB). It is unclear to what extent treatment of SDB can improve daytime hypoxemia. METHODS We performed a retrospective cohort study of obese hypoxemic individuals, all of whom underwent polysomnography, arterial blood gas analysis, and subsequent initiation of positive airway pressure (PAP) therapy for ...

Living tissues require a sufficient supply of oxygen for survival. An insufficient supply of oxygen may result from impairments of the respiration or oxygen transport systems, such as lung disease, heart disease, and anemia. Supplemental oxygen therapy increases the oxygen content in the lungs and blood oxygen saturation. The control of the oxygen flow is typically adjusted manually. This manua...

Chronic neonatal lung disease (CNLD) is defined as a supplemental oxygen requirement beyond 36 weeks' postmenstrual age, with more severely affected infants requiring oxygen beyond a full-term-equivalent age. Low-flow supplemental oxygen facilitates discharge from hospital of infants with CNLD who develop hypoxia in air. There is a lack of data on the most appropriate minimum mean target oxygen...

Normobaric supplemental oxygen can prolong seizures not caused by hyperbaric oxygen therapy. In addition, hyperbaric oxygen therapy can cause seizures. The mechanism of hyperbaric oxygen-induced seizures is unknown. We hypothesized that pretreatment with pyridoxine may delay the onset of hyperbaric oxygen-induced seizures, recognizing that pyridoxine is already an antidote for some epileptogeni...

Introduction: Pneumocephalus is the presence of air or gas within the cranial cavity. It can occur following otorhinolaryngological procedures. A small pneumocephalus spontaneously heals without any treatment. In severe cases, conservative therapy includes a 30-degree head elevation, avoidance of the Valsalva maneuver, analgesics, osmotic diuretics, and oxygen therapy.   Case Report: A 56-year-...

the six-minute walk test (6mwt) is a well-tolerated test which reflects daily activities and can be easily used in clinical practice. the 6mwt provides information about functional capacity, response to therapy and prognosis across a range of chronic cardiopulmonary conditions. moreover, the 6mwt is sensitive to the common therapies used for chronic obstructive pulmonary disease, such as pulmon...

Oxygenation Devices During cardiopulmonary emergencies use supplemental oxygen as soon as it is available. Rescue breathing (ventilation using exhaled air) will deliver approximately 16% to 17% inspired oxygen concentration to the patient, ideally producing an alveolar oxygen tension of 80 mm Hg. During cardiac arrest and CPR, tissue hypoxia occurs because of low cardiac output with reduced per...
