Nasal High Flow Oxygen Therapy

Nasal High Flow (NHF) oxygen therapy is a technique devised to deliver high flow oxygen in a maximally humidified, comfortable, and easily administered fashion. Conventional bubble humidifiers are most commonly used for humidifying medical gas delivered to spontaneously breathing patients, but the absolute humidity of the emergent gas remains low. Any time compressed gas is released the expansion results in significantly cooling and drying of the gas and when delivered directly especially in higher flows causes discomfort and increased airway resistance.

The Tobacco Wars

As an active member of NAMDRC for 30 years, and NAMDRC’s mission to advocate to reduce regulatory barriers to best care for our pulmonary patients. I strongly feel that we should be part of at least aware of the “tobacco wars”.


The recent ACCP Guideline recommends a three month course of anticoagulation for an episode of DVT or pulmonary embolism (venous thromboembolism) which occurs in association with a transient risk factor such as surgery, trauma or oral contraceptive use. The guideline recommends extended anticoagulation (no definite stop date) in patients with unprovoked venous thromboembolism (VTE).

December 20, 2016 - Literature Review

Probably all readers of this blog will have already read and thought about the Long-Term Oxygen Therapy Trial (LOTT) study, recently published in the New England Journal (NEJM. 2016; 375:1617–27). This landmark study looked at the role of supplemental oxygen in patients with COPD with either resting or exercise-induced moderate desaturations. This is the first large-scale oxygen study performed since the 1970s when the Nocturnal Oxygen Treatment Trial (NOTT) and Medical Research Council (MRC) studies were performed in the US and UK, respectively.
