A ventilator is a machine that mechanically moves breathable air in and out of the lungs to breathe for patients unable to do so on their own. There are different types of ventilators for various settings and patients, including transport ventilators for movement, ICU ventilators for greater control, and neonatal ventilators designed for preterm infants. Factors such as the patient's condition, diagnosis, lung compliance, and staff familiarity help determine which ventilator and mode is most appropriate for each individual patient.

Mechanical ventilation uses endotracheal intubation and a ventilator to replace spontaneous respiration and ventilation.
The ventilator provides the function of the respiratory muscles, endotracheal tube establishes a patent and unobstructed airway and the exogenous oxygen source gives a patient a therapeutic concentration of the gas.
THE IMPORTANCE OF MARTIAN ATMOSPHERE SAMPLE RETURN.Sérgio Sacani
The return of a sample of near-surface atmosphere from Mars would facilitate answers to several first-order science questions surrounding the formation and evolution of the planet. One of the important aspects of terrestrial planet formation in general is the role that primary atmospheres played in influencing the chemistry and structure of the planets and their antecedents. Studies of the martian atmosphere can be used to investigate the role of a primary atmosphere in its history. Atmosphere samples would also inform our understanding of the near-surface chemistry of the planet, and ultimately the prospects for life. High-precision isotopic analyses of constituent gases are needed to address these questions, requiring that the analyses are made on returned samples rather than in situ.
Professional air quality monitoring systems provide immediate, on-site data for analysis, compliance, and decision-making.
Monitor common gases, weather parameters, particulates.
Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.
Nutraceutical market, scope and growth: Herbal drug technologyLokesh Patil
As consumer awareness of health and wellness rises, the nutraceutical market—which includes goods like functional meals, drinks, and dietary supplements that provide health advantages beyond basic nutrition—is growing significantly. As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.
Richard's entangled aventures in wonderlandRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.

2. A ventilator is a machine which is designed to mechanically
move breathable air into and out of the lungs, to provide the
mechanism of breathing for a patient who is physically not able
to breathe sufficiently.
VENTILATION
It is a method of controlling the environment with the air , and
can be defined as the movement of air between the
environment and lungs via inhalation and exhalation.
Pulmonary ventilation
Alveolar ventilation
3.
4. Mechanical ventilation is a positive or negative pressure artificial breathing
device that can maintain ventilation and oxygen delivery for prolonged
periods.
It is indicated when the patient is unable to maintain safe levels of oxygen
or CO2 by spontaneous breathing even with the assistance of other oxygen
delivery devices.
FREQUENCY/RESPIRATION RATE: Breaths per unit time. At rest
12/min.
VENTILATION RATE: Total volume inspired or expired per unit time,
sometimes called as Minute Volume (MV) when measured per minute, to
avoid ambiguity usually measured as volume expired, VE.
5. Ventilator delivers gas to lungs using
positive pressure at certain rate.
The amount of gas delivered can be
limited by time pressure and volume.
The duration can be cycled by time
pressure and flow.
6. 1. Power source or Input power:
a). Electrically powered ventilators.
b). Pneumatically powered ventilators.
c). Combined powered ventilators.
2. Positive or negative pressure generator
3. Control system and circuits.
a.) Open and closed loop systems to control ventilator function.
b.) Control panel (user interference)
c.) Pneumatic circuit
4. Power transmission and conversion system.
5. Output (pressure, volume and flow waveform)
8. These are larger and usually run on AC
power(though virtually all contain a
battery to facilitate intra-facility
transport and as a back-up in the event
of a power failure).
It provides greater control of a wide
variety of parameters.
Many ICU ventilators also provide
visual feedback of each breathe through
graphics.
9. These are designed with the preterm
neonate in mind.
These are a specialized subset of ICU
ventilators that are designed to deliver the
smaller, more precise volumes and pressures
required to ventilate such patients
INDICATION FOR NEONATAL
VENTILATORS
1. Respiratory distress syndrome
2. Sepsis
3. Birth asphyxia
4. Meningitis
5. Pneumonia
10. These are specifically designed for non-invasive ventilator, and can also be
used at home, e.g., for treating sleep apnea or COPD.
It works by increasing the patient’s airway pressure through an
endotracheal or tracheostomy tube.
The positive pressure allows the air to flow into the airway until the
ventilator breathe is terminated.
Then the pressure drops to ‘0’ and the elastic recoil of the lungs and chest
wall push the tidal volume- breathe out through passive exhalation.
11. Here the air is withdrawn mechanically to produce a vacuum inside the
tank, thus creating negative pressure which in turn leads to expansion of
the chest.
It leads to decrease in intra-pulmonary pressure, and increases flow of
ambient air into the lungs.
As the vacuum is released, the pressure inside the tank equalizes the
ambient air pressure.
The elastic coil of the chest and lungs thus leads to passive exhalation.
12.
13. Frequency is from 60/min upto even 3000/min.
It is of two types:
a). Jets – It uses natural elastic recoil of the lungs, where expiration occurs
passively. It consists of a applying high pressure jet to the airways via a
cannula or endotracheal tube.
b). Oscillators – It uses a reciprocating piston which aid expiration on its
return stroke. Here expiration is active.
14. When a person has bilateral lung pathology, then this type of
ventilation is used.
Here two synchronized ventilators are used simultaneously.
It prevents ventilation -to- perfusion mismatch.
Treatment cost is expensive as two ventilators are required in
one set-up.
15. It can be used as a short-term measure, for e.g., during an operation or
critical illness.
Long-term ventilatory assistance are required in chronic illness, and may
be used at home, or in a nursing or rehabilitation center.
In positive pressure ventilator, additional measures can be required to
secure airway. The common employed method is intubation which provides
clear route for the air.
In negative pressure or non-invasive ventilator, there is no need to use any
adjunct.
16. It mainly depends upon the clinical condition of the patient on
presentation, diagnosis, patient’s respiratory drive, the compliance
of lungs and the chest wall, and the degree of synchronization.
Other factors can be familiarity of the staff with the equipment and
the availability of the equipment.
17. Vital Signs.
Oxygen Saturation in the blood.
Consciousness of the Patient.
Checks alarm function of the ventilator.
Secretions should be removed periodically.
