Masks for the face and respiratory infection

Cochrane Review searched for studies that compared facemasks and hand hygiene. Read This method included both facemasks used alone or in combination with other hand hygiene. The Cochrane Review identified 67 studies. 19 of these involved facemasks. 15 of these were included in the Summary of Findings tables. The Cochrane Review concluded that the use of facemasks and hand hygiene alone had no positive effect on respiratory infection.

Influence of facemasks upon respiratory infection

Recent research has shown a strong association between facemasks and lower incidence of respiratory infections such as influenza. These studies compared the effectiveness and standard hygiene practices to determine the difference. Facemasks are associated with lower rates of respiratory infections in patients with bacterial pneumonia. We will be discussing how facemasks can reduce the risk of developing respiratory infections in the general populace.

Effects of facemasks on hypoxemia

In a study, researchers used surgical and cloth facemasks in patients with chronic obstructive pulmonary disease. Both cloth and surgical masks had equal effectiveness in increasing oxygen saturation, and reducing carbon dioxide levels. The surgical and cloth masks did not cause hypoxemia or hypercarbia. In addition, the masks did not increase heart rate or decrease SpO2 or CO2 tension. These findings may reassure patients and increase usage. These findings could also help prevent the spread invasive surgical complications such as pathological gas exchange impairments.

Hypercapnia: Effects of facemasks

A number of recent studies have looked into the possible effects of facemasks. Many have concluded that they cause hypercapnia. While this condition can be life-threatening, the claim that facemasks cause hypercapnia is unsubstantiated. Although a mask does act as a barrier to aerosols, it still allows the passage of gas molecules, including carbon dioxide. Carbon dioxide molecules are smaller and more efficient than viruses. For example, COVID-19 is approximately 260 nanometers in diameter.

Non-medical Facemasks

The difference between medical and non-medical facial masks is not obvious. The difference lies in the filtration methods. The Bacterial filter efficiency (BFE), which requires expertise and can be tedious, is used to evaluate medical masks. Particle Filtration Efficiency tests (PFE), which are simpler and more readily implemented in the field, are used to evaluate non-medical facemasks. A better understanding of the filtration characteristics of non-medical masks will allow for comparisons between different types.
