Keeping astronauts healthy in space is not easy – new training programs will prepare students to practice medicine thousands of kilometers from Earth

Published

on

In the approaching decade, more people will go to space than ever before as human spaceflight enters a new era. NASA, the European Space Agency and other government agencies are working together develop manned missions beyond the Moon. At the identical time, these agencies are working with private corporations to use new technologies to lower the costs of space exploration.

Companies like SpaceX, Blue Origin and Sierra Space have developed vehicles with reusable amplifiers, automated flight systems and light-weight materials support these space missions. Some even have their very own ambitions to construct private space stations, lunar bases or mining operations in the approaching many years.

However, as these technologies and partnerships rapidly expand the supply of spaceflight, new challenges arise. First, maintaining the health and performance of the astronaut crew. My team researchers and educators on the University of Colorado and others around the globe want to solve this problem.

As spaceflight expands, astronauts will need access to medical care on longer journeys and business flights.

New medical challenges in space

NASA astronauts are some of essentially the most sensible and healthiest people in the world. In one study, astronauts undergo extensive medical and psychological tests disqualified 26% of candidates from the ultimate round. This rigorous inspection and testing process effectively reduces the chance of a medical incident occurring during a mission.

However, as spaceflight becomes more accessible, astronaut crews on business missions will likely make up the bulk of people traveling to space in the approaching years. Private missions will be short and will remain in close Earth orbit for the foreseeable future, but this will likely be done by private crews less training and more chronic health conditions than skilled astronauts currently living and dealing in space.

One sec experiments on the International Space Station have extensively studied the conventional physiological changes that occur in the human body in weightlessness, there is no data on the behavior of common chronic diseases, akin to diabetes and hypertension, in the space environment.

This industrial development also creates opportunities for long-duration missions to the Moon and Mars. Due to the length of the mission and the gap from Earth, professionally astronauts participating in these missions will experience long-term weightlessness leading to bone and muscle loss, communication delays ranging from a number of seconds to 40 minutes, and extreme isolation lasting months or years.

Crews must operate autonomously while being exposed to new threats, akin to lunar and Martian dust. Due to the fuel needed for these missions, resources will be limited to the bottom possible mass and volume.

As a result, mission planners will have to make difficult decisions in advance to determine what supplies are really needed, with limited or unavailable options for resupplying food, water, and medicine. For example, in space there could also be radiation and humidity contained in the spacecraft cause medicines to spoil faster and change into unavailable and even toxic to crew members.

The space station crew has already done this access to the flight surgeon at Mission Control to help manage health care in the identical way telehealth is used on Earth. However, crews on distant planets will have to perform medical care and procedures themselves.

In the event of a medical emergency, crews may not have the opportunity to evacuate to Earth. Unlike a space station, where medical evacuation to Earth can occur in lower than 24 hours, lunar evacuations could take weeks. Evacuation from Mars may not be possible for months and even years.

Put simply, the present approach to spaceflight medical care will not meet the needs of future business and skilled astronauts. Scientists will need to develop new technologies and novel training approaches to prepare future service providers to treat conditions in space.

Current aerospace medicine leaders are either experts in aerospace engineering or medicine, but rarely do experts have formal training or full knowledge of each fields. And these disciplines often cannot speak their very own language, neither literally nor figuratively.

Training the subsequent generations

To meet the changing demands of human spaceflight, educators and universities are looking to train specialists who understand each the restrictions of the human body and the restrictions of engineering design.

Some schools and hospitals, e.g University of Texas Medical Branch, conduct training programs for medical school graduates in the sector of aviation medicine. Others, akin to UCLA AND Massachusetts General Hospitalthey’ve specialized training programs in aerospace medicine, but these are currently geared toward fully trained emergency medicine physicians.

My team on the University of Colorado created a program that integrates human physiology and engineering principles to educate medical students to think like engineers.

This program goals to help students understand human health and performance in the spaceflight environment. He approaches these topics from engineering design and limits the prospect of finding solutions to the challenges astronauts will face.

One of our hottest classes is called Mars in simulated surface environments. In this class, students explore engineering and medical scenarios in a simulated Martian environment in the Utah desert. Students navigate the challenges of working and caring in a space suit and in a desolate, Mars-like landscape.

The stress of simulations will be real for students, they usually learn the way to use their combined skills to take care of other crew members.

Educational programs like these and others are designed to produce trained professionals who understand each patient care and the procedural nature of engineering design and may mix the 2, each for space tourists in orbit and as a pioneer to the surface of one other planets.

A new era of spaceflight is upon us, and these programs are already training experts to make space accessible and secure.

Women are less likely to undergo cardiopulmonary resuscitation than men. Training on breast mannequins could be helpful

Published

on

By

If someone’s heart suddenly stops beating, this may increasingly have happened minutes of life. Performing cardiopulmonary resuscitation may increase their probabilities of survival. Cardiopulmonary resuscitation keeps blood pumping, delivering oxygen to the brain and vital organs until specialized treatment arrives.

However, research shows that bystanders are less likely to intervene to perform cardiopulmonary resuscitation if the person is a girl. AND latest Australian study analyzed 4,491 cardiac arrest cases between 2017 and 2019 and located that bystanders were more likely to perform CPR on men (74%) than on women (65%).

Could this be partly because CPR training mannequins (so-called dummies) shouldn’t have breasts? Our recent research we checked out mannequins available all over the world to train people to perform CPR and located that 95% of them were flat-chested.

Anatomically, breasts don’t change the cardiopulmonary resuscitation technique. However, they’ll influence whether people try to accomplish that – and hesitation at these key moments could mean the difference between life and death.

Differences in heart health

Cardiovascular diseases – including heart disease, stroke and cardiac arrest – are probably the most common diseases important reason behind death for ladies all over the world.

But if a girl goes into cardiac arrest outside the hospital (meaning her heart stops pumping air properly), that is actually what happens. 10% less likely receive cardiopulmonary resuscitation than a person. Women too less likely survive cardiopulmonary resuscitation and are at greater risk of brain damage following cardiac arrest.

These are just among the many health inequalities experienced by women, in addition to transgender and non-binary people. Compared to men, their symptoms they are more likely to be rejected or misdiagnosed, or it could take longer to receive a diagnosis.

Reluctance of the witness

There can also be growth evidence women are less likely to start cardiopulmonary resuscitation compared to men.

This may be partly due to the concerns of those being accused of sexual harassmentworry may cause damage (in some cases based on the assumption that ladies are more “fragile”) and discomfort related to touching women’s breasts.

Bystanders may also get into trouble recognition the lady has a cardiac arrest.

Even in simulated scenarios, researchers found that interveners were less likely to remove women’s clothing prepare for resuscitationcompared to men. And there have been women less likely to receive Cardiopulmonary resuscitation or defibrillation (an electrical charge to restart the center) – even when the training was in the shape of a web based game that didn’t require touching anyone.

There is evidence of how people behave in resuscitation training scenarios reflects what they do in real emergency situations. This means it is amazingly vital to train people to recognize cardiac arrest and prepare for intervention, no matter gender or body type.

Attached to men’s bodies

Very Cardiopulmonary resuscitation training resources depict male bodies or don’t specify gender. If bodies shouldn’t have breasts, it’s a male default.

For example, the 12 months 2022 test taking a look at CPR training in North, Central, and South America, it was found that nearly all of available mannequins were white (88%), male (94%), and slim (99%).

This research reflects what we see in our work once we train other healthcare professionals to perform cardiopulmonary resuscitation. We noticed that every one the mannequins available for training are flat chested. One of us (Rebecca) had difficulty finding training mannequins with breasts.

Single mannequin with breasts

Our recent research we checked what cardiopulmonary resuscitation mannequins are available and the way diverse they are. In 2023, we identified 20 cardiopulmonary resuscitation mannequins in the worldwide market. Mannequins are often torsos with no head and without arms.

Of the 20 available, five (25%) were sold as “female”, but only considered one of them had breasts. This implies that 95% of obtainable CPR training mannequins were flat-chested.

We also checked out other diversity characteristics, including skin tone and bigger bodies. We found that 65% had more than one skin tone available, but just one had a bigger body. Further research is required on the impact of those elements on bystanders when performing CPR.

Breasts don’t change cardiopulmonary resuscitation technique

Cardiopulmonary resuscitation technique doesn’t change when someone has breasts. The barriers are cultural. And although you could feel uncomfortable, starting cardiopulmonary resuscitation as soon as possible can save your life.

Signs that somebody may have cardiopulmonary resuscitation include not respiration properly or completely or not responding to you.

Perform effective cardiopulmonary resuscitationit’s best to:

  • place the heel of your hand in the middle of your chest

  • place your second hand on top of the primary and interlace your fingers (keep your arms straight)

  • press firmly to a depth of about 5 cm before releasing

  • press your chest with a frequency of 100-120 beats per minute (you may sing a song) in your head to show you how to keep time!)

An example of performing cardiopulmonary resuscitation – using a flat-chest manikin.

What a couple of defibrillator?

You haven’t got to remove someone’s bra to perform CPR. But you could need to accomplish that if a defibrillator is required.

AND defibrillator is a tool that uses an electrical charge to restart the center. An underwired bra may cause minor skin burns when the debrillator pads apply an electrical charge. However, in case you cannot take your bra off, don’t let it delay your care.

What should change?

Our research highlights the necessity for a big selection of breast CPR training mannequins, in addition to a wide range of body sizes.

Training resources need to higher prepare people to intervene and perform CPR on individuals with breasts. We also need greater education on the chance of developing and dying from heart disease in women.

Ant stings can be painful. Here’s how to avoid getting stung this summer (and what to do if it happens)

Published

on

By

The starting of summer is just a couple of days away, and plenty of of us will be looking forward to long, sunny days spent on the beach, by the pool, camping or having a picnic within the park.

Insects love summer too. Most of them right then grow and feed. However, this shared appreciation of the season can sometimes lead to conflict.

Insects have long been preyed upon by many species, including birds, mammals, amphibians, and other insects. Accordingly, quite a lot of defense mechanisms have evolved – perhaps none more familiar to humans than the sting.

Many ants have a stinger on their rear end which they use to deliver venom. It will not be the sting itself that causes pain, but relatively venom. Ant venom accommodates a mix of various chemicals, a few of which have evolved specifically to manipulate the nerve endings in our skin to cause pain.

Let’s take a have a look at the several ant stings chances are you’ll experience this summer in Australia and how to respond.

Bull ants

Bull ants (also often called bulldog ants, jumper ants, or jumper ants) are large for an ant. Some species can grow to length 4 centimeters. They are easily identified by their large eyes, long mandibles (jaws), and aggressive nature.

Their sting is immediate, hot, sharp and unambiguous, similar to that of a honey bee. The intense pain will only last a couple of minutes before being replaced by redness and swelling across the sting site.

There are many differing kinds of bull ants in Australia.

Green-headed ants

Green-headed ants are also called green ants (but not to be confused with green ants). green tree ants northern Australia, which do not sting). Green-headed ants are common and love our lawns.

About Length 6 millimetersthey’re much smaller than bull ants. They can be recognized by their shiny green-purple exoskeleton.

Green-headed ants are frequently less aggressive than bull ants, but they can still deliver a big sting. The pain from a green ant sting can construct up step by step and cause intense, sticky pain.

Fire ants

Fire ants (or imported red fire ants) are native to South America. They were detected first in Brisbane in 2001it probably moved in containers and has since spread across south-east Queensland.

Fire ants are reddish brown and black and range in size from Length 2–6 millimeters.

You will almost certainly encounter fire ants of their nests, which appear like a pile of loose dirt. A hearth ant nest has no obvious entrance, which is way to distinguish it from other similar ant nests.

Disturbing a hearth ant nest will awaken an offended mass of a whole bunch of ants and expose you to being stung.

The initial pain from a single sting seems like an intense, hot itch, although it can be controlled. However, fire ant stings rarely occur in the only digits. One ant can sting multiple times, and plenty of ants can sting one person, which can lead to a whole bunch of stings. A hearth ant sting can cause pus-filled ulcers and scarring in the next days.

If you reside in an area where fire ants are present, it’s price taking a couple of minutes to learn how to do this recognize and report their.

Electric ants

Electric ants is one other nasty random import, coming from Central and South America. Currently limited to Cairns and surroundingsthese are tiny (1.5 millimeters long) yellow ants.

Like fire ants, these ants are frequently defensive, so lots of them will sting without delay. Their sting is more painful than you’ll expect from such a tiny creature. I compare it to being showered with red, hot sparks.

If you think that you see electric ants, please report it Biosecurity in Queensland.

Australian ants should not the worst

You may be surprised to hear that Australian ants don’t even make it to the rostrum when it comes to essentially the most painful ant stings. The winners include: harvester ants (North and South America), which cause severe, sticky pain, comparable to a drill slowly rotating in a muscle – for up to 12 hours.

The gold medal goes to the sting of the South and Central American bullet ant, which has been described How:

Pure, intense, sensible pain. It’s like walking on burning charcoal with a 3-inch nail stuck in your heel.

How to avoid getting stung (and what to do if you do)

Fortunately, the answer is frequently quite simple. Look around before you sit on the bottom or unfolded a picnic blanket, avoiding places where you see ant nests or a lot of foraging ants.

The selection of footwear might also be necessary. In my experience, most stings occur on the feet of those wearing thongs.

If you get stung, generally the situation will improve by itself. The pain often subsides after a couple of minutes (sometimes slightly longer within the case of a green ant sting). The redness, swelling and itching that sometimes follows may last for several days.

In the meantime, if mandatory, ice pack it will help with the pain. If it’s particularly bad, a topical numbing cream containing lidocaine may provide temporary relief. You can get it over-the-counter at a pharmacy.

A small proportion of individuals may experience an allergic response to ant stings. In very severe cases this may include respiratory problems or ingestion. If you or a loved one experiences these symptoms after an ant sting, you need to seek urgent medical attention.
