Nitric Oxide (NO) is an inhaled gas that works via relaxation of the smooth muscles to dilate the blood vessels most commonly in the lungs (drugs.com, 2015). It is a blend of NO and Nitrogen and is used as a treatment for Acute Respiratory Distress Syndrome (ARDS) and Persistent Pulmonary Hypertension of the Newborn (PPHN) (Kumc.edu, 2015). This essays purpose is to inform about how it works, the uses for treatment, the type of patients most likely to benefit from NO, how it’s delivered, dosage, and also the hazards and complications that may come about when treating with NO.
NO is has a very similar name in regards to Nitrous Oxide, more commonly known as “laughing gas” but they should never be confused with each other because of the colossal

Before NO is administered, the patient should be as stable as possible so sedation, blood pH, FiO2, and in rare cases muscle relaxers should be considered. For mechanically ventilated patients, when the patient is prepped, NO is administered with the use of delivery system that is able to put out a constant concentration throughout the patients breathing cycle (Eagans, 2013). Delivery systems, such as the INOmax DS can also be used with a facemask or nasal cannula (Eagan’s, 2013). When withdrawing NO therapy, the patient should be closely monitored because some patients that have not been weaned off correctly may develop worsening effects like hypoxemia. This is called the rebound effect and it happens because when a patient is given NO, it alters the body’s normal production of NO (Eagans, 2013). This is why the FiO2 needs to be increased frequently then reduced slowly to baseline over the course of 2 hours when the NO is no longer being used on the patient (Eagans, …show more content…
When high concentrations of NO is given to a patient, it can cause fatal acute pulmonary edema (Eagans, 2013) NO is also said to be linked with direct cellular damage even when given in low doses. Some side effects of NO include blurred vision, confusion, dizziness, sweating, chest discomfort, tightness in the chest, trouble breathing, methemoglobinemia, hypotension, atelectasis, stridor, and hyperglycemia (Drugs.com, 2015). NO can be used for a quick reduction in right ventricular afterload which may cause an increase left ventricular filling pressure in some cases (Eagans, 2013). A lot of the toxic effects of NO are caused by Nitrogen Dioxide (NO2), which is produced whenever NO comes in contact with Oxygen and is more toxic than NO where levels greater then 10 ppm can lead to problems with cell damage, pulmonary edema, hemorrhage, and death (Eagans, 2013). According to nih.gov, there are specific guidelines that should be followed in order to lessen the risk of toxicity when using NO, they are as follows: administer the lowest effective dose of NO with a maximum dose of 40-80 ppm, administer the lowest possible concentration of O2, monitor oxygen, nitric oxide, and nitrogen dioxide concentrations, and minimize exposure time of NO to oxygen as much as possible (nih.gov, 2002). Studies have shown that some patients, more than others, have proven difficult to wean off NO. This is
This essay describes how the anaesthetic machine and airway management equipment are prepared in operating theatres and discusses how they are ensured safe for use. It evaluates the Association of Anaesthetists of Great Britain and Ireland (AAGBI) guidelines related to safe practice and the preparation of the ET tubes, laryngeal masks, guedels, Naso pharyngeal airways and the laryngoscope. The function of the anaesthetic workstation is to deliver a mixture of anaesthetic agents and gases safely to the patient during the induction process and throughout surgery. In addition, it also provides ventilation to support breathing and monitors the patient’s vital signs to minimise the anaesthetic risks to the patient whilst in the care of health professionals. The pre-use check is vital to patient safety as an inadequate check of the anaesthetic machine or airway management equipment can and does lead to significant harm of the patient including mortality (Medicines and Healthcare Products Regulatory Agency (MHRA), 2008 and Magee, 2012).
Ascertaining the adequacy of gaseous exchange is the major purpose of the respiratory assessment. The components of respiratory assessment comprises of rate, rhythm, quality of breathing, degree of effort, cough, skin colour, deformities and mental status (Moore, 2007). RR is a primary indicator among other components that assists health professionals to record the baseline findings of current ventilatory functions and to identify physiological respiratory deterioration. For instance, increased RR (tachypnoea) and tidal volume indicate the body’s attempt to correct hypoxaemia and hypercapnia (Cretikos, Bellomo, Hillman, Chen, Finfer, & Flabouris, 2008). The inclusive use of a respiratory assessment on a patient could lead to numerous potential benefits. Firstly, initial findings of respiratory assessment reveals baseline data of patient’s respiratory functions. Secondly, if the patient is on respiratory medication such as salbutamol and ipratropium bromide, the respiratory assessment enables nurses to measure the effectiveness of medications and patient’s compliance towards those medications (Cretikos, Bellomo, Hillman, Chen, Finfer, & Flabouris, 2008). Thirdly, it facilitates early identification of respiratory complications and it has the potential to reduce the risk of significant clinical
Nitric oxide is a gaseous, diatomic molecule that plays an important role as a mediator of cardiac function, working largely as a vasodilator in the cardiovascular system. Nitric oxide is synthesized by a family of enzymes known as nitric oxide synthases (...
Nitrous oxide is administered via a face mask and is used to take the edge off of your nerves. This form of sedation is great for uncomplicated procedures and for patients experiencing only mild levels of fear or anxiety. If you fall into this category, nitrous oxide sedation may be for you.
According to Batshaw, Roizen, and Lotrecchiano (2013), patent ductus arteriosus (PDA) is “the persistence of a fetal passage permitting blood to bypass the lungs” (p. 745). This is an inherited heart condition in which the ductus, a small pathway between the pulmonary and the aortic, valves remain open. This cardiovascular problem usually occurs in low birth weight infants. The blood vessels usually naturally closes after birth (Batshaw et al., 2013, p. 96). It becomes atypical if it remains open after the neonatal period. The structure usually closes in typical developing newborns around the initial 24 hours, and anatomical closure is supposed to follow several weeks later (Stanford Children’s Health, 2015). At the point when the ductus arteriosus stays open, the blood from the oxygen-rich aorta blends with the oxygen-poor pulmonary artery causing the higher chance of blood pressure in the lung pathways (U. S. Department of Health and Human Services, 2011). Certain children who have patent ductus arteriosus may be given medication, relying upon the circumstance to standardize the blood and oxygen levels until surgery is performed. Doctor can treat this condition by providing pharmaceutical medicine, catheter-based procedures, and surgery (U. S. Department of Health and Human Services, 2011).
But often the symptoms do not stop at acute withdrawal. After the body makes initial adjustments to the absence of drugs, the changes that have occurred in the brain still need time to revert back to their original state. During this period, a variety of symptoms known as Post-Acute Withdrawal Syndrome (PAWS) begin to occur. In the book Uppers, Downers, All Arounders, published by CNS Productions, authors Darryl Inaba and William Cohen define PAWS as “a group of emotional and physical symptoms that appear after major withdrawal symptoms have abated” (Inaba & Cohen, 2011).
NAS has turned into an epidemic espicially in the state of Tennessee a little more than 320 babies were born with NAS in 2013. Tennessee was the first state to start keeping track of the number of cases of NAS. NAS occurs when pregnant women take drugs such as heroin, codeine, oxycodone, methadone, or buprenorphine (“Babies are being born addicted to drugs”). This happens when the substances pass through the placenta that connects the baby to its mother. Then the baby becomes dependent on the drug like the mother. Hospitals began treating these cases with morphine, by administering a dosage of morphine every few hours as needed and reducing the dosage until the baby was better. During this process doctors need to keep a look out for the babies since the morphine can cause them to stop breathing. A baby born with NAS usually suffers from low birth weight and respiratory problems. Heroin and cocaine are some of the most common drugs being abused, and they both have short and long term effects other than withdrawal symptoms: Such as ph...
Several skills are beneficial to the nurse and paramedic, but perhaps one of the most important skills is the ability to place an intravenous catheter into a vein. This procedure is most commonly referred to as “starting an IV”. In today’s medical community, intravenous cannulation is necessary for the administration of many antibiotics and other therapeutic drugs. Listed below are the procedures and guidelines for starting a successful IV. Following these instructions will provide a positive experience for the patient and clinician.
... of the need of duplicate revascularization over balloon angioplasty [75]. Both pre- and post -conditioning appears to protect cardiomyocytes at the time of reperfusion therapy. Ischemic post-conditioning is a chain of repetitive intermissions of coronary blood flow administered after a period of ischemia. Inhibition of ONOO−-induced nitro-oxidative stress might pay a critical role in postcon-mediated cardioprotection [76]. Iliodromitis et al also reported that postcon-mediated cardioprotection was in cohorts with reduced nitro-oxidative stress in vivo. The acknowledgment that iNOS activation in cardiac myocytes could be advantageous and that nitriate/NO could have both beneficial and detrimental effects, lead to the dose of 1400W iNOS inhibitor being chosen to significantly inhibit, but not restrict, increase in the level of myocardial iNOS activity after MI [77]
The common gasses used in diving include compressed air and Nitrox. Nitrox is a mixture of gas composed of nitrogen and oxygen. Nitrox also contains normal air, which is 78% nitrogen, 21% oxygen and 1% of other gasses, primarily argon.
