The key clinical features of the scenario that lead to administering of oxygen included;

  •  Post  cardiac arrest
  • Low blood oxygen levels
  • Chronic and acute hypoxemia
  • Symptoms of shock
  • Low cardiac output
  • Low metabolic acidosis
  • Chronic type two respiratory failures (Belsen 2012).

Based on the prevailing condition, the physiological rationale for administering oxygen was;

    • To gain informed consent.
    • In order to provide reassurance and mental support.
    • To be able to ensure maximum benefit is usually obtained from treatment.
    • Environmental and physiological humidifications are sufficient.
    • All the care should be ensured of which it is only shipped over a given individual foundation.
    • To allow detection of increase function of breathing.
    • Head bobbing demonstrates the particular use of the strict mastoid muscle with each breath.
    • Signal of severe respiratory distress.
    • Indication regarding reduced blood oxygen amounts (Eric 2012).

On administering associated with oxygen, it was expected to incorporate higher oxygenation of the blood, plus tissue appears in order to stimulate cell operating, this process usually allows for the ability of the cells to heal and be able to combat infection. In addition, o2 therapy normally promotes plus stimulates the growth in addition to development of new bloodstream vessels (John 2012). Hyperbaric oxygen therapy also presents a reliable platform for lowered swelling, thereby, reducing by a greater percentage typically the damage and harm coming from acute brain injuries.

On analyzing the landscape of incidence, the possible risk factors included;

    • Poor life-style
    • Sensory/ communication disability
    • Hazardous atmosphere (John 2012).

Based on personal perspective, these could get the recommendation and consideration based n the landscape to ensure safety;

    • Include the requirement for sufficient oxygen
    • Need for proper nutrition
    • Optimum heat
    • Cleaning regarding the entire area in addition to room
    • Generate awareness of the negative effects of drugs in addition to the safety requirement

Mechanism by which an opioid agonist (such as heroin), causes respiratory depression (Jerome 2007).

Based on the current generation, drug addiction is a worldwide problem of opioid dependence. Most addicts inject opioid with dirty and shared syringe. The pharmacodynamic response to an opioid usually has a base on the receptors that bind it, its affinity and affection for that receptor, and mostly whether the respective opioid is an agonist or an antagonist  respiratory depression and physical dependence by the μ2 receptor.  It contains Buprenorphine hydrochloride which is an established, active substance. Buprenorphine hydrochloride is designated chemically as (2S)-2-[17-Cyclopropylmethyl-4, 5α-epoxy-3-hydroxy-6-methoxy-6α, 14-ethano-14α-morphinan-7α-yl]-3, 3 dimethylbutan-2-ol hydrochloride

Pharmacodynamic rationale for administering naloxone

Naloxone is intended to be administered cautiously to persons. Considering such scenarios, a rapid and complete reversal of narcotic effects may gradually generate an extremely acute and severe abstinence syndrome that may affect the person. The acuteness and seriousness of that syndrome highly depends upon the degree of physical addiction and the dose of antagonist administered. In the case of serious respiratory depression in a physically addicted individual, the antagonist, when indicated, is supposed to be administered with extreme care and caution, it should be closely monitored, with the aid of appropriate titration with minimal doses than usual. The patient who has successfully managed to respond to naloxone shhould be always monitored and left under surveillance, and a series of repeated doses should be administered, as necessary, this is due to reason that the duration of some narcotics action may exceed that of naloxone.

Mechanism of action of naloxone

Naloxone is famously known for its vehement ability in prevention and reversal of the effects of opioid such as the adverse effect of respiratory depression. It consists of essentially pure narcotic antagonist which lacks the agonistic unlike other narcotic antagonists’ exhibit as property characteristic. It also exhibits essentially no pharmacological activity which restricts it from producing respiratory depression. According to the recent research carried out on its mechanism of action, it has been depicted that naloxone antagonizes the opioid effects simply by competing for the same receptor sites (Nathan 2012).

Its onset of action is generally apparent within 2 minutes after naloxone i.v. has been administered.

Pharmacological considerations of current approaches to narcotic overdose

 For the partial reversal of narcotic depression based on the use and management of narcotics during surgery, minimal doses of naloxone are extremely sufficient. The dose is expected to be titrated based on the patient’s response. For the initial reversal of respiratory depression, naloxone should be injected gradually in increments of 100 to 200 µg (0.1 to 0.2 mg) i.v. at 2 to 3 minute intervals until the optimum degree of reversal is attained. Adequate ventilation and alertness without significant pain or discomfort should be realized. Overdose of naloxone may results in complicated reversal of analgesia and also rise in one’s blood pressure levels. On the other hand, in case there is reversal conducted in a rapid manner, it may result in constant nausea, frequent vomiting, and sweating (Tracy 2012).
