In older people, a variety of illnesses and issues frequently lead to increased impairment through immobility. Improvements in mobility are almost always achievable, even in the most immobile elderly individuals. Immobility is frequently unavoidable, but many of its negative effects can be. Pressure sores, DVT, PE, postural hypotension, hypostatic pneumonia/chest infections, osteoporosis, foot drop, contractures, etc. are common issues brought on by immobility. Numerous issues are brought on by immobility in various body systems and organs.

Improvements in mobility are almost always achievable, even in the most immobile elderly individuals. Immobility is frequently unavoidable, but many of its negative effects can be. Mobility enhancements can enhance patient wellbeing, lessen the frequency and severity of complications, and make life easier for caregivers.
Several environmental, psychological, and physical factors can make older people immobile. Musculoskeletal, neurological, and cardiovascular disorders are the most frequent causes. Immobility caused by these disorders frequently results from pain.
Bedsores, also known as pressure sores or pressure ulcers, are wounds to the skin and underlying tissue brought on by sustained pressure. The skin covering bony parts of the body, such as the heels, ankles, hips, and tailbone, is where bedsores most frequently appear.
Those with medical conditions that make it difficult for them to change positions, necessitate the use of a wheelchair, or keep them confined to a bed for an extended period of time are most at risk for developing bedsores.
Bed sores can appear suddenly and are frequently hard to treat. Several factors can aid in healing and help prevent some bedsores.
Deep vein thrombosis, (DVT)
Calf muscle pumping and breathing-induced suction in the inferior vena cava help blood flow from the limbs back to the heart. Legs do not move and respirations are not as deep when someone is immobile in bed.
Blood flow to the lower limbs is slowed as a result. Leg vein compression from the bed and bones slows blood flow even more and may harm the vein lining, causing platelets to clump together and form a thrombus.
Signs and Symptoms
Risk factors
Prevention of DVT
Pulmonary embolism, (PE)
After a DVT, a thrombus in the calf may migrate along the right side of the heart's venous circulation before being ensnared in the pulmonary circulation channels. When a thrombus detaches from the vessel wall and moves freely through the circulation, it is referred to as an embolus.
Signs and Symptoms
Prevention
Treatment
Postural hypotension
The diminished effect of gravity causes vaso-dilation in the patient. The patient may experience nausea and dizziness when they stand up for the first time or move from a horizontal to a vertical position.
Prevention
If possible allow the patient to:
Increase in cardiac workload
Prevention
Hypostatic pneumonia/chest infections
occurs when the lungs become overfilled with typical bronchial secretions. Infection and accumulation of lung tissue constitute pneumonia.
Signs and Symptoms
Prevention
Osteoporosis
Reduced activity results in demineralization of the bones, which can alter their size, strength, chemistry, and appearance.
Normally, this only causes issues in the medium to long term, but the first week of immobility can cause some increased calcium secretion in the urine.
Prevention
Stress bones whenever possible, e.g occasional standing if possible.
Muscle wasting and joint stiffness
After 3 to 7 days of bed rest, muscle weakness and atrophy can start to appear. These changes are most pronounced in the "anti-gravity" muscles used for standing and walking.
The collagen fibers and connective tissue of the tendons, ligaments, and joint capsules stiffen and become dense when immobile, leading to further loss of motion and joint stiffness within a few days that may take months to reverse.
Contractures
a persistent contraction of a muscle or group of muscles brought on by the shortening and fibrosis of the muscle fibers, which results in a loss of function.
They develop as a result of poor posture and limb alignment while in bed. may begin after a week or so of inactivity.
Footdrop
A condition that makes it difficult for the patient to keep his foot in the proper position. Gravity and the additional weight of the bedclothes pull the foot downward, shortening the calf muscles and tendons as a result.
Prevention
Urinary calculi
Demineralization of the bone releases calcium. The precipitation of calcium results in the formation of calculi or stones as a result of this and urinary stasis or immobility.
Signs and Symptoms
Prevention
Ensure adequate fluid intake of 3000 mls each day.
Urinary retention
Calcium concentration in the urine reduces the sensitivity of the bladder, which can result in urine retention. This problem can be made worse by positioning oneself improperly in bed when urinating.
Signs and Symptoms of Urinary Retention
Prevention
Urinary incontinence
As stated before, urinary calculi and urinary retention can occur. These may lead to incontinence by the irritation of the urinary sphincter by a stone or increased pressure from urine when the bladder's capacity is reached.
These situations can be compounded by poorly situated toilets and if the patient has to wait too long for a bed pan or assistance from a nurse.
Prevention
As for retention, but in addition:
Urinary infection
If the bladder cannot completely drain, the stagnant urine becomes contaminated, which is made worse by ascensing bacteria.
Signs and Symptoms
Prevention
Constipation
Prevention
Decreased basal metabolic rate
Care deficits

Write short note on DVT
Deep Vein Thrombosis (DVT)
Calf muscle pumping and breathing-induced suction in the inferior vena cava help blood flow from the extremities back to the heart.
Legs do not move and respirations are not as deep when someone is immobile in bed.
Blood flow to the lower limbs is slowed as a result.
Leg vein compression from the bed and bones slows blood flow even more and may harm the vein lining, causing platelets to clump together and form a thrombus.

Prevention of DVT
Write short note on PE.
Pulmonary embolism, (PE)
If the thrombus in the calf travels via the venous circulation, the right side of the heart, and then becomes trapped in the pulmonary circulation arteries, it may happen after a DVT. A thrombus is referred to be an embolus when it separates from the vessel wall and travels freely through the circulation.
Signs and Symptoms
Prevention
Dependent largely upon prevention of DVT and/or early detection of DVT.
Treatment
Anticoagulation, fibrinolytic therapy, embolectomy
Explain about urinary retention.
Urinary Retention
The bladder's sensitivity is reduced by the amount of calcium in the urine. This may result in urine retention; this condition may be made worse by an inappropriate bed position for urinating.
