Some ventilator modes will allow a patient to initiate breaths, so it’s always possible that a patient could breathe above the rate set by the therapist. If that occurs, and we really need the patient to breathe at the prescribed rate, we usually sedate them in order to achieve this.
1. What is a Ventilator? A ventilator is a machine that supports breathing, and is used mainly in a hospital or rehabilitation setting. Medical issues or conditions that make it hard for the patient to breathe necessitate that a ventilator is used to aid the breathing process. 2.
In a wide variety of settings, nurses are increasingly likely to care for patients on mechanical ventilators. Let’s assume you’re one of them. What do you need to know to plan your shift?
If heavy sedation is reduced and you can achieve, for example, RASS scores of zero to negative one such that patients can participate and pass a spontaneous awakening trial, and then effectively do a spontaneous breathing trial, you can get the patient off the ventilator faster.

Sometimes you'll be dealing with patients with special circumstances. These lessons will show you how to assess an intubated patient who may have upper airway swelling and/or neuromuscular disease.
To ease distress in the patient and family, teach them why mechanical ventilation is needed and emphasize the positive outcomes it can provide. Each time you enter the patient’s room, explain what you’re doing. Reinforce the need and reason for multiple assessments and procedures, such as laboratory tests and X-rays.
Ventilator-associated pneumonia (VAP) is a major complication of mechanical ventilation. Much research has focused on how best to prevent VAP. The Institute for Healthcare Improvement includes the following components in its best-practices VAP prevention “bundle”: 1 Keep the head of the bed elevated 30 to 45 degrees at all times, if patient condition allows. Healthcare providers tend to overestimate bed elevation, so gauge it by looking at the bed frame rather than by simply estimating. 2 Every day, provide sedation “vacations” and assess readiness to extubate, indicated by vital signs and arterial blood gas values within normal ranges as well as the patient taking breaths on her own. 3 Provide peptic ulcer disease prophylaxis, as with a histamine-2 blocker such as famotidine. 4 Provide deep vein thrombosis prophylaxis, as with an intermittent compression device. 5 Perform oral care with chlorhexidine daily.
respiratory rate, the number of breaths provided by the ventilator each minute. Manually count the patient’s respiratory rate, because she may be taking her own breaths at a rate above the ventilator setting. fraction of inspired oxygen (FiO2), expressed as a percentage (room air is 21%).
PSV allows spontaneously breathing patients to take their own amount of TV at their own rate. A/C and continuous mandatory ventilation provide a set TV at a set respiratory rate. SIMV delivers a set volume at a set rate, but lets patients initiate their own breaths in synchrony with the ventilator.
Hyperoxygenate the patient before and after suctioning to help prevent oxygen desaturation. Don’t instill normal saline solution into the endotracheal tube in an attempt to promote secretion removal. Limit suctioning pressure to the lowest level needed to remove secretions. Suction for the shortest duration possible.
Monitor the patient’s blood pressure every 2 to 4 hours, especially after ventilator settings are changed or adjusted. Mechanical ventilation causes thoracic-cavity pressure to rise on inspiration, which puts pressure on blood vessels and may reduce blood flow to the heart; as a result, blood pressure may drop.

Ventilators, often referred to as life support machines, are used in intensive care units for patients who cannot breathe on their own.
You might be sedated, if you are lucky. But you won’t be sedated the whole time.”. Those words come from Jerry King, RRT , an assistant professor in the School of Health Professions, at the University of Alabama at Birmingham. He teaches students at UAB how to use a ventilator.
In addition to rate, FiO2 and PEEP, the MD or respiratory therapist will adjust how the ventilator delivers oxygen to the patient. We call this the “ventilator mode.” Modes can be broadly categorized as pressure controlled and volume controlled.
Ventilator basics: two alarms you must know. You’ll soon learn that ventilators (and everything else in the critical care setting) come with a lot of sound effects. There are two alarms I want you to be hypervigilent about…the high-pressure alarm and the low-pressure alarm.
That’s why respiratory therapists go to school for a couple of years, to learn the intricacies of ventilator and respiratory management.
CPAP is another mode used in the weaning process, or with patients with a chronic tracheostomy for airway management. The continuous positive airway pressure provided in this mode provides the patient with some pressure support while allowing them to control their respiratory rate and volume. A lot of times, we’ll have a patient who does CPAP all day and then “rests” on a more supportive ventilator mode at night.
The respiratory therapist or MD will determine the correct respiratory rate for the patient based off their unique physiologic needs. For example, if the patient is acidotic because they’re retaining their CO2, we can try increasing the respiratory rate to help the patient “blow off” their CO2. Some ventilator modes will allow a patient to initiate breaths, so it’s always possible that a patient could breathe above the rate set by the therapist. If that occurs, and we really need the patient to breathe at the prescribed rate, we usually sedate them in order to achieve this.
In volume-controlled modes, we are delivering a certain amount of volume to the patient. The most common of these is a mode called Assist Control Ventilation or ACV. In this mode the patient triggers the ventilator for each breath and the ventilator “assists” the patient by delivering a controlled/pre-determined volume to the patient. Volumes are typically calculated at 8ml/kg IBW (ideal body weight). It’s important to note that even though the patient is triggering the breaths, we will set a backup rate on the ventilator so that if the patient doesn’t meet that minimum rate, the ventilator will kick in and deliver a breath.
These are the external intercostal muscles, the scalenes and sternomastoids (during inspiration) and the abdominal muscles and internal intercostal muscles (during expiration). Negative pressure ventilation: Under normal circumstances, humans breathe utilizing negative pressure ventilation. When the diaphragm drops and the intercostal muscles pull ...
Ventilators keep oxygen going to the brain, the heart and the kidneys. All while we hope the infection will ease, and the lungs will begin to improve. These machines can’t fix the terrible damage the virus is causing, and if the virus erupts, the lungs will get even stiffer, as hard as a stale marshmallow.
Specially trained health care workers insert a 10-inch-long tube connected to a ventilator through the mouth and into the windpipe. The ventilator delivers more oxygen into the lungs at pressure high enough to open up the stiffened lungs. It’s called life support for a reason; it buys us time.
At the very end of each are clusters of microscopic sacs called alveoli. The lining of each sac is so thin that air floats through them into the red blood cells. These millions of alveoli are so soft, so gentle, that a healthy lung has almost no substance. Touching it feels like reaching into a bowl of whipped cream.
If patients get worse after being put on a ventilator, critical care doctors are having to ask their family members what they want done. Covid-19 is too contagious to have these conversations in person, so they are being done over the phone. It is yet another heartbreaking reality of dying during a pandemic.
It is yet another heartbreaking reality of dying during a pandemic. Patients cannot tell us what they want. Family members aren’t able to be with patients and may not know what they would want. No one can make these choices for us, and no one will know what choices we would make unless we tell them.
Say: The two main safety program goals are: (1) reduce the risk of patient harms associated with mechanical ventilation and (2) achieve significant improvements in teamwork and safety culture in ICUs. By getting patients off of the ventilator faster, you will reduce the risk of patient harms associated with mechanical ventilation.
One is the use of subglottic secretion drainage endotracheal tubes in all patients that are expected to be ventilated for greater than 72 hours. Subglottic secretion drainage endotracheal tubes are an effective tool for reducing VAP and getting patients off the ventilator faster.
Historically, many researchers considered VAP to be perhaps the most deadly healthcare-associated infection associated with mechanical ventilation. In fact, there is a 35 percent mortality rate for ventilated patients with VAP. Therefore, it carries significant impact for patients.
If sedation is necessary, interrupt sedation at least once a day and assess the patient's readiness to breathe and readiness to extubate, while pairing spontaneous breathing trials with spontaneous awakening trials. In other words, conduct a spontaneous breathing trial with the patient off of all sedatives.
Examples of short-term complications include: VAP, sepsis, progression to acute respiratory distress syndrome, pulmonary embolism, barotrauma, and pulmonary edema.
A retrospective cohort study conducted between 2006 and 2011 at an academic tertiary care center calculated and compared VAE hazard ratios, antibiotic exposures, microbiology, attributable morbidity, and attributable mortality for all VAE tiers.
Previous VAP surveillance definitions were subjective and non-reproducible. Over the last few years, the Centers for Disease Control and Prevention or CDC has redefined these into what we call ventilator-associated events, or VAEs, which are identified with a combination of very objective criteria:
What's fundamental in understanding the purpose of ventilators for COVID-19 is that they're currently only being turned to as a final measure to save a patient's life when without one, a person is likely not to survive the disease.
You may be on one for a long time. When a COVID-19 patient requires mechanical ventilation support, it's not just for a couple days. Two to three weeks is not an unusual time for patients to be on ventilators — sometimes longer.
Here's a rundown of what being on a ventilator with the coronavirus is like: It's not comfortable. Mechanical ventilators are a form of life support. Because of the invasive nature of hooking someone up to a breathing machine, patients must be heavily sedated to relax and tolerate the discomfort.
While patients over 80 have a low survival rate on a ventilator, Rovner says someone who is otherwise mostly healthy with rapidly progressing COVID-19 in their 50s, 60s or 70s would be recommended a ventilator to let their lungs heal.
Over time, doctors use lower volumes of oxygen with lower pressure to cause less injury, but ventilators are still "not completely safe and harm free ," says Hill. It's difficult to come off a ventilator. Doing so takes a long process called weaning, where patients gradually begin breathing on their own.
Rovner says health care providers are backing away from intubating patients (part of the ventilator process where a tube is insert ed into the windpipe) as early as before. Now, doctors are first leaning on other methods of breathing assistance, like the use of high-flow oxygen — a non-invasive form of ventilator.
