Does Nail Polish Really Affect Pulse Oxygen Reading?

MedicalResearch.com: What is the background for this study?

Response: Nail varnish and acrylic nails are common accessories and as such are commonly encountered by an array of healthcare professionals in various scenarios when SpO2 readings may be part of patient care.. Colloquially there was a wide variety of approaches and beliefs as to whether or not these treatments impacted on SpO2 readings. This is due to the fact that the Digital Pulse oximetry relies on the passing of a wavelength of light through a pulsatile nailbed to a sensor on the opposite side of the finger tip in order to read SpO2 levels. Any potential interference to this process by polish of certain hues, or acrylic was therefor believed to impact on the resultant readings

As such it was decided to analyse the actual level of knowledge and variety of approaches to the issue by means of a multisite study involving Consultants, NCHDs, and nursing staff in areas where this issue may arise. A second, experimental part of the study was set up using healthy volunteers and venous congestion and hypoxia modelling. Nail varnish of differing hues and acrylic nails were applied and results of SpO2 readout in healthy and pathological models with and without nail treatments applies were analysed.

MedicalResearch.com: What is the background for this study? What are the main findings?

  • Pneumonia is the leading cause of mortality in children globally.
  • Oxygen is an essential therapy for children with hypoxemic pneumonia, but is not available in many resource-limited and rural areas.
  • Our innovation, solar powered oxygen delivery, harnesses freely available sun and air to delivery oxygen to patients independent of grid electricity.
  • We performed a randomized controlled trial of solar powered oxygen delivery, compared to standard oxygen delivery using compressed oxygen cylinders in children with hypoxemia hospitalized at two centres in Uganda.
  • Solar powered oxygen was non-inferior to cylinder oxygen with respect to clinical outcomes, and offers advantages in terms of reliability, simplicity, and cost.

COPD Patients On Oxygen Therapy Should Be Warned Of Burn Risks

Medical Research: What is the background for this study? What are the main findings?

Dr. Sharma: Thirty-five years ago, two multicenter trials reported substantial improvements in survival and quality of life with continuous oxygen therapy in the treatment of severe hypoxemia associated with chronic obstructive pulmonary disease (COPD).

Notably, aside from smoking cessation, no other medical intervention therapy has been shown to improve survival for patients with COPD. It is estimated that upto a third of the patients who are prescribed oxygen continue to smoke.

Using large claims data of Medicare beneficiaries with COPD, we found that patients with COPD who had a burn injury were more likely to have been prescribed oxygen therapy in the preceding 90 days compared to the control subjects.

Patients with COPD on oxygen who had burn injury, the face, head and neck region were more commonly involved. In the U.S. oxygen is prescribed to an estimated one million Medicare beneficiaries, based on our estimates a physician would have to treat 1,421 patients with oxygen therapy for one year to cause one burn injury.

Pediatric Bronchiolitis: Improved Oxygen Saturation Reduced Hospitalizations

Medical Research: What are the main findings of this study?

Dr. Schuh: Our study shows that in previously healthy infants presenting to the Emergency Department with mild to moderate bronchiolitis (a viral lower respiratory tract disease producing breathing distress) who had their oxygen saturation measurements artificially elevated by a physiologically small amount experienced significantly reduced rate of hospitalizations within 72 hours compared to infants with unaltered oximetry readings.
