Rheumatic heart disease is a condition in which the heart valves have been permanently damaged by rheumatic fever. The heart valve damage may start shortly after untreated or under-treated streptococcal infection such as strep throat or scarlet fever.
Cardiogenic shock is a condition of diminished cardiac output that severely impairs cardiac perfusion. In this condition in which the heart suddenly can't pump enough blood to meet the body's needs.
Cirrhosis is a late stage of scarring (fibrosis) of the liver caused by many forms of liver diseases and conditions, such as hepatitis and chronic alcoholism.
Cardiomyopathy, or heart muscle disease, is a type of progressive heart disease in which the heart is abnormally enlarged, thickened, and/or stiffened. As a result, the heart muscle's ability to pump blood is less efficient, often causing heart failure and the backup of blood into the lungs or rest of the body. The disease can also cause abnormal heart rhythms.

Medical Technology Tackles New Health Care Demand - Research Report - March 2...pchutichetpong
M Capital Group (“MCG”) predicts that with, against, despite, and even without the global pandemic, the medical technology (MedTech) industry shows signs of continuous healthy growth, driven by smaller, faster, and cheaper devices, growing demand for home-based applications, technological innovation, strategic acquisitions, investments, and SPAC listings. MCG predicts that this should reflects itself in annual growth of over 6%, well beyond 2028.
According to Chris Mouchabhani, Managing Partner at M Capital Group, “Despite all economic scenarios that one may consider, beyond overall economic shocks, medical technology should remain one of the most promising and robust sectors over the short to medium term and well beyond 2028.”
There is a movement towards home-based care for the elderly, next generation scanning and MRI devices, wearable technology, artificial intelligence incorporation, and online connectivity. Experts also see a focus on predictive, preventive, personalized, participatory, and precision medicine, with rising levels of integration of home care and technological innovation.
The average cost of treatment has been rising across the board, creating additional financial burdens to governments, healthcare providers and insurance companies. According to MCG, cost-per-inpatient-stay in the United States alone rose on average annually by over 13% between 2014 to 2021, leading MedTech to focus research efforts on optimized medical equipment at lower price points, whilst emphasizing portability and ease of use. Namely, 46% of the 1,008 medical technology companies in the 2021 MedTech Innovator (“MTI”) database are focusing on prevention, wellness, detection, or diagnosis, signaling a clear push for preventive care to also tackle costs.
In addition, there has also been a lasting impact on consumer and medical demand for home care, supported by the pandemic. Lockdowns, closure of care facilities, and healthcare systems subjected to capacity pressure, accelerated demand away from traditional inpatient care. Now, outpatient care solutions are driving industry production, with nearly 70% of recent diagnostics start-up companies producing products in areas such as ambulatory clinics, at-home care, and self-administered diagnostics.

1. Ganesh is a 22 years old medical student was driving his car and
accident. He was found to be agitated and complaining of
abdominal pain. His airway was patent. At the scene, her
breathing at 32 breaths/ min with BP of 90/60 mmHg and a
pulse of 130 Bpm. He was placed in a hard cervical collar on a
back board and transported to the emergency room.Upon arrival
his vital signs were the same, with temp. of 36 degree celsius C.
His abdomen was markedly distended. His hands and feet were
cold. A urinary catheter revealed dark yellow urine. His Hb is 7.
3. INTRODUCTION
•Shock is a serious, life-threatening medical emergency
and one of the most common causes of death for
critically ill people.
•Shock leads to insufficient blood flow which reaches
the body tissues. As the blood carries oxygen and
nutrients around the body
•The process of blood entering the tissues is called
perfusion, so when perfusion is not occurring properly
this is called a hypo perfusion.
4. DEFINITION OF SHOCK
A physiological state characterized by a significant, systemic
reduction in tissue perfusion, resulting in decreased tissue
oxygen delivery and insufficient removal of cellular
metabolic products, resulting in tissue injury.
6. INITIAL STAGE
During this stage………. The hypoperfusional state
Mitochondria being unable to
produce ATP.
Which results in systemic
metabolic acidosis.
These compounds getting
removed by the liver requires
oxygen, which is absent.
Cellular Hypoxia,
Lack of oxygen and atp
The cells perform anaerobic
respiration.
This causes a build-up of lactic
and pyruvic acid
7. INTERMEDIATE STAGE
•This stage is characterised by the body employing physiological
mechanisms, including neural, hormonal and bio-chemical
mechanisms in an attempt to reverse the condition.

attempt to raise the pH
of the blood.
8. Progressive stage
•When the cause of the crisis not successfully treated,
the shock will proceed to the progressive stage and
the compensatory mechanism begin to fail.
•The prolonged Vasoconstriction will also cause the
vital organs to be compromised due to Reduced
perfusion.

10. Types of shock
• In 1972 Hinshaw and Cox suggested the following classification which is still used today.
1. Hypovolemic Shock
a) hemorrhagic shock
b) Traumatic shock
c) Surgical shock
d) Dehydration shock
2. Cardiogenic Shock
3. Distributive Shock /warm shock/vasogenic shock
a) Septic Shock,
b) Anaphylactic Shock
c) Neurogenic Shock
4. Obstructive Shock
5. Endocrine Shock
11. DEFINITION OF HYPOVOLEMIC SHOCK
DEFINATION-
Hypovolemic shock is an emergency condition in which
severe blood and fluid loss make the heart unable to pump
enough blood to the body due to decreased preload
•Hypovolemic shock is most common type of shock.
•Also called as cold shock.
16. •Decrease CVP
•Decreased intestinal motility due to intestinal
hypoperfusion
•systemic vasoconstriction may lead to tissue ischemia,
hypoxia, and eventually to altered cellular function and
global organ dysfunction.
•Collapsed peripheral veins
•Delayed return of color to the nail buds
•Confusion,
•Drowsiness
•Coma
17. DIAGNOSIS EVALVATION-
•History and physical examination - A history of
trauma, overt bleeding, or recent surgery is present for
patients with hemorrhagic shock.
•For the non-hemorrhagic hypovolemic shock due to
fluid losses, history and physical should attempt to
identify possible GI, renal, open wounds, skin, or third-
spacing as a cause of extracellular fluid loss.
18. •Blood pressure
•Blood test are done to find out if any damage has occur
in the kidney or liver.
•CBC
•SERUM ELECTROLYTE
•ABG to determine blood amount of oxygen in blood.
•ECG
•CT Scan
19. MEDICAL MANAGEMENT
Major goals in treating hypovolemic shock are to -
•Restore intravascular volume to reverse the sequence
of events leading to inadequate tissue perfusion
•Redistribute fluid volume
•Correct the underlying cause of the fluid loss as
quickly as possible.
20. TREATMENT OF THE UNDERLYING
•If the patient is hemorrhaging, efforts are made to stop the
bleeding. This may involve applying pressure to the bleeding
site or surgery to stop internal bleeding.
•Anti-fibrinolytic administration to patients with severe
bleeding within 3 hours of traumatic injury appears to
decrease death from major bleeding
•If the cause of the hypovolemia is diarrhea or vomiting,
medications to treat diarrhea and vomiting are administered as
efforts are made simultaneously to identify and treat the cause.
•In the elderly patient, dehydration may be the cause of
hypovolemic shock.
21. FLUID AND BLOOD REPLACEMENT
•At least two large-gauge intravenous lines are inserted
to establish access for fluid administration. Two
intravenous lines allow simultaneous administration of
fluid, medications, and blood component therapy if
required.
•Redistribution of fluid provide the position to the
patient.
22. PHARMACOLOGIC THERAPY
•If the underlying cause of the hypovolemia is dehydration,
medications are also administered to reverse the cause of
the de-hydration. For example, insulin is administered if
dehydration is secondary to hyperglycemia;
•Desmopressin (DDAVP) is administered for diabetes
insipidus, antidiarrheal agents for diarrhea, and antiemetic
medications for vomiting.
23. Nursing Management
•Hypovolemic shock can be prevented in some instances by
closely monitoring patients who are at risk for fluid deficits and
assisting with fluid replacement before intravascular volume is
depleted.
•In other circumstances, hypovolemic shock cannot be pre-
vented, and nursing care focuses on assisting with treatment
targeted at treating its cause and restoring intravascular volume.
•General nursing measures include ensuring safe administration
of prescribed fluids and medications and documenting their
administration and effects.
24. •Administering blood transfusions safely is a vital nursing
role.
•In emergency situations, it is important to obtain blood
specimens quickly to obtain a baseline complete blood count
and to type and cross-match the blood in anticipation of blood
transfusions.
•The patient who receives a transfusion of blood products
must be monitored closely for adverse effects
•Fluid replacement complications can occur, often when large
volumes are administered rapidly. Therefore, the nurse
monitors the patient closely for cardiovascular overload and
pulmonary edema.
25. •Hemodynamic pressure, vital signs, arterial blood
gases, hemoglobin and hematocrit levels, and fluid
intake and output are among the parameters monitored.
•The patient's temperature should also be monitored
closely to ensure that rapid fluid resuscitation does not
precipitate hypothermia.
•The nurse needs to monitor cardiac and respiratory
status closely and report changes in blood pressure,
pulse pressure, heart rate,
26. SUMMARY-
•Today we have discussed introduction, definition of
hypovolemic shock , their causes /risk factors.
Classification of shock its pathophysiology, clinical
manifestations, assessment and diagnostic findings,
medical and nursing management.
27. CONCLUSION
•Hypovolemic shock is an emergency condition in
which severe blood and fluid loss make the heart
unable to pump enough blood to the body this type of
shock can cause may organ to stop working.
Survival
and outcomes improve with early perfusion, adequate
oxvgenation and identification with appropriate
treatment of the cause of shock
