Can Dogs Detect Infected Patients with Covid 19? – Virus 20

 

A dog in the middle of street, just for illustration only.

As we might all know that dogs are “excellent” to use their sense. It is fact that dogs have smell capability 10,000 times more than human to detect crucial substances include:

- blood

- illegal electronic devices

- explosive devices

- illegal drugs

In medical world, dogs are trained to diagnosed diseases such as cancer. They success to recognize cancer types such as:

- skin cancer

- bladder cancer

- breast cancer.

By understanding that diseases such as cancer, Parkinson’s and even malaria may cause specific odors, thus dogs may help to detect the diseases.

Dogs are standing under the tree in our neighborhood.

Scientists have trained dogs to help them to detect patients infected with corona virus (Sars Cov 2).

Dogs are projected to be able to detect the Covid 19, even the patients have no symptoms.

Researchers from University of Veterinary Medicine, Hannover, Germany have good primary result:

- dogs can be trained to sniff out virus (Sars Cov 2) infection

- dogs may determine who got infected by virus or virus free persons through smelling the saliva

- the accuracy (success rate) is 94%

Just for comparisons, the available tests and methods have accuracy ranging from 84% to 100%.

Hence, 94% accuracy of detection by using dogs is “not bad,” at least for early warning purposes.

Then, suspect infected patients may be examined by more accurate devices furthermore.

Roses in the Late Summer - Gardening and hobby 4

Fig – 01. Red and light pink roses

Roses disappeared from our garden now, they are blooming quite longer, could be months (more than 20 weeks), from mid Spring to to late Summer or early Fall.

In nature, roses have less than 10 colors, but breeders develop more than 60 colors or combined colors recently.

- watering regularly

- using organic mulch

Organic mulch is mixed of material include grass clippings, shredded bark, pine needles, sawdust and wood chips. The functions mulch are:

- improve quality of soil

Measuring Oxygen Level in the Blood - Virus 19

Pulse Oximeter (Credit to Insider)

We always hear and familiar with the word “ventilator,” a life saving device during current pandemic Covid 19.

Why Covid 19 patients need ventilator?

You might know that it is because low concentration of oxygen level in the blood, and the fact that virus drown the lung, thus lung can’t inhale and exhale air in normal ways.

How we can say our oxygen level is normal?

There are two common available methods:

1) Measurement of PaO2 (partial pressure of oxygen dissolved).

- the normal reading is 80 mm Hg

2) Measurement of Oxygen saturation or pulse Oxygen (SpO2).

- the normal level of oxygen is 95% to 100%

The lawn mower, just for illustration

You may have medical device called Pulse Oximeter to measure Oxygen saturation or pulse Oxygen at your home.

Oximeters are available in many stores or Pharmacy such as Walgreen, CVS, Target, Walmart or Amazon.

Prices of Pulse Oximeter are ranging from US$ 4.77 to US$ 299. Quite reasonable for me if price is about US$ 19.99.

Moreover, in case your Pulse Oxygen level below 90%, it is mean the oxygen level is not normal.

In addition to lower pulse oxygen level, people should go to hospital and need treatments when they face with conditions of:

- serious illness

- difficult to breathing

Do you think that should you have this kind of medical device available at your home?

- 4 part of solution is water

Then, find the perfect spot. The location of feeder is eye-catching spot for birds. Usually in the bright place with little bit shades.
