Proper daily usage is key to any sleep apnea treatment program. With the VSL integrated SMS alerts and notices patients will be informed when their treatment program falls outside of normal limits for Usage or mask leakage issues. Patients will also be able to view thier monitor reports securly from their mobile devices by sending a simple reply to request a link to the report.

sms screens


SMS text messages are sent daily to patients who don't meet minimum thresholds for usage and will be instructed how to resolve issues or to contact their provider for assistance. Providers can also review monitoring data with patients via conference calls during treatment.

Study Objectives: To evaluate the effect of an employer-mandated obstructive sleep apnea (OSA) program on the risk of serious preventable truck crashes. Methods: Data are from the rst large-scale, employer-mandated program to screen, diagnose, and monitor OSA treatment adherence in the US trucking industry. A retrospective analysis of cohorts was constructed: polysomnogram-diagnosed drivers (OSA positive n = 1,613, OSA negative n = 403) were matched to control drivers unlikely to have OSA (n = 2,016) on two factors affecting crash risk, experience-at-hire and length of job tenure; tenure was matched on the date of each diagnosed driver’s polysomnogram. Auto-adjusting positive airway pressure (APAP) treatment was provided to all cases (i.e. OSA positive drivers); treatment adherence was objectively monitored. Cases were grouped by treatment adherence: “Full Adherence” (n = 682), “Partial Adherence” (n = 571), or “No Adherence” (n = 360). Preventable Department-of-Transportation-reportable crashes/100,000 miles were compared across study subgroups. Robustness was assessed. 

Results: After the matching date, “No Adherence” cases had a preventable Department of Transportation-reportable crash rate that was vefold greater 

(incidence rate ratio = 4.97, 95% con dence interval: 2.09, 10.63) than that of matched controls (0.070 versus 0.014 per 100,000 miles). The crash rate of “Full Adherence” cases was statistically similar to controls (incidence rate ratio = 1.02, 95% con dence interval: 0.48, 2.04; 0.014 per 100,000 miles). 

Conclusions: Nontreatment-adherent OSA-positive drivers had a vefold greater risk of serious preventable crashes, but were discharged or quit rapidly, being retained only one-third as long as other subjects. Thus, the mandated program removed risky nontreatment-adherent drivers and retained adherent drivers at the study rm. Current regulations allow nonadherent OSA cases to drive at another rm by keeping their diagnosis private.

Limited data from commercial drivers is a major reason for the US Federal Motor Carrier Safety Administration’s failure to require screening for obstructive sleep apnea (OSA). We present the results of the  rst large-scale, employer program to screen, diagnose, and monitor OSA treatment adherence in the US trucking industry. Among drivers in whom OSA was diagnosed through the program, those adherent with employer-provided positive airway pressure treatment had crash risks similar to controls, whereas nonadherent drivers had a  vefold greater preventable crash risk after adjustment for miles driven and driving experience. Therefore, our results strongly support federal OSA regulations for commercial drivers. Future research should improve the calibration of criteria and thresholds for OSA treatment success.

We all know that sleep is an essential part of our wellbeing and happiness, but how much do we actually need? The average person spends up to 33% of their lives sleeping, but when asked if they get enough sleep, most people will say, no. Most people agree that getting a good night's rest is vital, however how many of us really make getting the proper amount of sleep a priority. Especially when we have so many entertainment options at our finger tips and ample supplies of coffee for those early morning meetings. We have become a society that has forgotten what "being really, truly rested" feels like.
