A pneumatic tube system (PTS) is a cost-effective, rapid transport modality that utilizes induced pressure changes. We evaluated the clinical importance of 2 transport modalities, human courier and PTS, for blood gas specimens. ⋯ The difference in the PO2 and PaCO2 of paired (walked vs tubed) arterial and venous blood gas specimens demonstrated a slight bias. PaCO2 values demonstrated the greatest bias, however not clinically important. Thus, PTS transport does not impact clinical interpretations of blood gas values.

Mechanically assisted coughing with mechanical in-exsufflation (MI-E) is recommended for noninvasive management of respiratory secretions in amyotrophic lateral sclerosis (ALS). To improve the effectiveness of the technique, a new device combining MI-E with high-frequency oscillations (HFO) has been developed. This work aimed to assess the effect of HFO on the cough peak flow generated by MI-E in medically stable subjects with ALS. ⋯ The addition of HFO to mechanically assisted coughing with MI-E does not have an effect on the cough peak flow of medically stable subjects with ALS.

In several studies, low spirometric levels have been shown to increase the success rates of smoking cessation, whereas other studies have indicated that pulmonary function has no effects on quitting smoking. Given the fact that there are contradictory results on this subject, we aimed to investigate the effect of identifying airway obstruction via spirometry and its explanation to subjects on the success rate of smoking cessation in the short term. ⋯ Advanced age and the presence of obstruction on PFT increase the success of smoking cessation. Pulmonary function tests should be performed on all patients who apply to smoking cessation out-patient clinics, and patients should be informed about their condition.

E-cigarettes are a diverse set of devices that are designed for pulmonary delivery of nicotine through an aerosol, usually consisting of propylene glycol, nicotine, and flavorings. The devices heat the nicotine solution using a battery-powered circuit and deliver the resulting vapor into the proximal airways and lung. ⋯ Pending regulation by the FDA will enforce limited disclosures on the industry but will not directly impact safety or efficacy. Meanwhile, respiratory health practitioners will need to tailor their discussions with patients, taking into account the broad range of existing effective smoking cessation techniques, including pharmaceutical nicotine replacement therapy.

Randomized Controlled Trial
Exploring the Benefits to Caregivers of a Family-Oriented Pulmonary Rehabilitation Program.
COPD is a highly incapacitating disease, particularly among older people, implying significant burden for family caregivers. Involving caregivers in comprehensive pulmonary rehabilitation programs might benefit their functional coping to care demands; however, there is no objective evidence to sustain such assumption. This study is a secondary analysis aiming to analyze the effects of a family-based pulmonary rehabilitation program on close family caregivers of older subjects with COPD. ⋯ The findings provide valuable evidence to recommend the inclusion of COPD family caregivers in comprehensive pulmonary rehabilitation. Family-oriented pulmonary rehabilitation maximizes caregivers' adaptive coping and potentially prevents negative psychological outcomes; however, further research is needed.
