Sleep Quality and Pulmonary Function in the Healthy Elderly: Discussion

We observed multiple significant correlations between indices of sleep quality and daytime PFTs in a group of healthy older persons, particularly those with low sleep efficiency. These relationships between variations in sleep quality and PFTs represent an extension of earlier research demonstrating that sleep deprivation results in worsened pulmonary function the following day. The present […]

Sleep Quality and Pulmonary Function in the Healthy Elderly: Results

A total of 48 subjects met criteria for inclusion in the study. The mean age of our subjects was 69.6 years (range, 60 to 87 years). There were 21 women and 27 men. Sleep quality variables are reported in Table 1; mean pulmonary function data are reported in Table 2. Good sleepers had significantly greater […]

Sleep Quality and Pulmonary Function in the Healthy Elderly: Data Analysis

Data Analysis In order to index sleep disturbance, we chose several measurements reported to reflect sleep quality in older persons, including the following: total sleep time; sleep efficiency (time asleep/time in bed); number of body movement artifacts; and the percentage of sleep time spent in stages 0, 1, 2, 3, and 4, and REM sleep. […]

Sleep Quality and Pulmonary Function in the Healthy Elderly: Materials and Methods

“Lights-out” was as close to 11:00 pm as possible, with wake up at 6:00 or 6:30 am; however, as we were trying to emulate routines that subjects followed at home, they were allowed out of bed to go to the bathroom or to turn on the light to read, if they desired. Apparatus included a Grass (model 78) polygraph […]

Sleep Quality and Pulmonary Function in the Healthy Elderly

Loss of sleep results in deterioration of pulmonary function in normal humans and causes modest worsening of pulmonary function in patients with moderate chronic obstructive pulmonary disease. Since gross sleep disturbances cause worsening of routine PFTs, we wondered if more subtle variations in sleep quality and pulmonary function might be related in normal humans. To […]

Pyogenic Vertebral Osteomyelitis Presenting as Exudative Pleural Effusion: Case 3

Comment: This diabetic woman presented with P mira-bilis bacteremia and an exudative pleural effusion infected with three organisms including Proteus. The enterococci and diphtheroids might have been contaminants. After an extensive and unsuccessful search for pneumonia, neurologic signs and symptoms led to the diagnosis of vertebral osteomyelitis caused by P mirahilis. The delay of 42 days before the diagnosis of […]

Long-term Efficiency of Home Nasal Mask Ventilation in Patients With Diffuse Bronchiectasis and Severe Chronic Respiratory Failure: Completion

Our study did not investigate the mechanisms of action of NMV in our patients. We can postulate that these mechanisms do not appear to be different from those proposed in other etiologies of respiratory failure: improvement in alveolar ventilation and distribution of ventilation, rest of the respiratory muscles, and resetting of the respiratoiy drives. If […]
