Respiratory stability

In stroke patients presenting to the ED, the first goal of treatment is immediate cardiac and respiratory stabilization. The systemic blood pressure is most often elevated in the setting of an acute stroke as the result of a catecholamine surge, and if the patient is hypotensive, the clinician should consider a concomitant cardiac process, such as myocardial infarction (MI), congestive heart failure (CHF), or pulmonary embolism (PE). 

A primary advantage of etomidate is its ability to preserve cardiovascular and respiratory stability both cardiac output and diastolic pressure are well maintained. Use of etomidate may offer some advantage to the patient with compromised myocardial oxygen or blood supply or both, since it produces mild coronary vasodilation. Thus, coronary vascular resistance decreases with no change in perfusion pressure. Preservation of diastolic perfusion pressure may be particularly important when myocardial blood supply cannot be increased by autoregulation.

Cardiac and respiratory stabilization are the first priorities following pentazocine poisoning. The patient s airway should be patent and adequate ventilation assured. If the patient has either inadequate ventilation or a poor gag reflex, then the patient may be at risk for subsequent CO2 narcosis with worsening acidosis or aspiration. If necessary, endotracheal tube intubation should be performed. Close monitoring of the patient s pulmonary exam should be performed to assure that pulmonary edema does not develop. The health care providers should place the patient on continuous cardiac monitoring with pulse oximetry and make frequent neurological checks. 

Patient examination findings depend on the particular moment in the course of the disease. In the initial phases, the range of ventilatory movements is satisfactory, the cough maneuver is normal, the mucus production is low, and the subject is able to carry out the Valsalva maneuver. Respiratory stability starts to be at risk when ventilatory mechanics symptoms... 

Some of the criteria used in the selection of a suitable agent are effectiveness in extremely small concentrations time to onset of action effectiveness through various routes of entry into the body, such as the respiratory tract, eyes, and skin stability in long-term storage and ease of dissernination in feasible munitions. 

An inhaled sympathomimetic, such as albuterol, may be prescribed initially. Salmeterol, a long-acting (5-agonist, is contraindicated because of its slowed onset of action. During an acute bronchospasm, the nurse checks the blood pressure pulse, respiratory rate, and response to the drug every 15 to 35 minutes until the patient s condition stabilizes and respiratory distress is relieved. 

Using a random mutagenesis approach, respiratory-deficient (34) and temperature-sensitive (46, 47) mutants of the Rieske protein of the yeast bc complex have been selected. A large fraction of the point mutants had changes of residues in the bottom of the cluster binding subdomain (the loop /S7-/38) and in the Pro loop comprising residues 174-180 of the ISF (Fig. 9 see Section III,B,3) this indicates the importance of the Pro loop for the stability of the protein.

Depending upon the location and severity of the stroke at admission, patients may have cardiac and/or respiratory instability at the time of presentation to the emergency department (ED). They may need to be stabilized hemodynamically or intubated for airway protection or respiratory distress. Blood pressure management is often a crucial management issue, and the use of vasopressor or antihypertensive medications is common. In stroke patients at risk for malignant cerebral... 

The mammalian immune system protects the body from infection by many complex strategies. The most vigorous defense is performed by white blood cells known as granulocytes. These cells consume oxygen in response to microbial infections. This oxidative process, called the respiratory burst, has recently been proven to produce stabilized hvDOchlorite antimicrobials (bredominantlv bv neutroDhils) and stabilized... 

In biochemical systems, acid-base and redox reactions are essential. Electron transfer plays an obvious, crucial role in photosynthesis, and redox reactions are central to the response to oxidative stress, and to the innate immune system and inflammatory response. Acid-base and proton transfer reactions are a part of most enzyme mechanisms, and are also closely linked to protein folding and stability. Proton and electron transfer are often coupled, as in almost all the steps of the mitochondrial respiratory chain.
