Why Electronic Devices Use DC Supply Instead Of AC Supply?

Electronic devices primarily use Direct Current
(DC) instead of Alternating Current (AC) for several fundamental reasons rooted in the nature of electronic circuits and the components that constitute these devices. Hereโ€™s a comprehensive exploration of why DC supply is favored in electronic devices.

1. Consistency and Stability

2. Stable Voltage Levels:
DC provides a constant voltage level, which is essential for the stable operation of most electronic components and circuits. Stability is crucial for components like semiconductors (transistors, diodes, integrated circuits) that rely on specific voltage levels for proper functioning.

3. No Frequency Interference:
DC supply eliminates concerns about frequency interference with device operation, which can be a significant consideration with AC.

4: Directional Flow:
Most electronic components, such as diodes and transistors, inherently allow current to flow in one direction, aligning naturally with DCโ€™s unidirectional flow. ACโ€™s changing direction would render these components ineffective or damage them.

5: Operational Requirement:
Integrated circuits (ICs), which form the backbone of modern electronic devices, require a constant DC supply to function accurately. ICs and microchips cannot operate directly on AC without a rectification stage to convert it to Dc.

6:Ease of Voltage Regulation:
It is easier to regulate DC voltage to the precise levels needed by electronic components. Voltage can be stepped down efficiently using simple circuits or switched-mode power supplies (SMPS) to accommodate the sensitive nature of electronic device.

7: Better Energy Storage.

DC is compatible with battery technology, allowing for energy storage. This compatibility is crucial for portable devices like smartphones, Laptops and electric vehicles.

In summary, the predominance of DC supply in electronic devices is due to the fundamental requirements of electronic circuitry and components, which necessitate stable and precise power delivery incompatible with the the inherent characteristics of AC power. Consequently.

TEE is a specialized ultrasound technique that employs high-frequency sound waves to generate detailed images of the heart and its surrounding structures. Unlike conventional echocardiography, which involves placing a transducer on the chest, TEE involves the insertion of a probe down the esophagus, positioning it directly behind the heart. This proximity allows for unparalleled clarity and precision in imaging.

The working principle of TEE is rooted in the science of ultrasound. The TEE probe emits sound waves that bounce off cardiac structures, creating echoes. These echoes are then captured by the probe and translated into real-time, high-resolution images. This dynamic visualization enables clinicians to assess cardiac function, identify anomalies, and monitor real-time changes during surgical interventions.

๐Ÿซ€The HOLTER MONITOR was invented by Dr. Norman J. Holter, an American biophysicist & electrical engineer. Dr. Holter developed the Holter monitor in the 1940s.

His invention revolutionized the way medical professionals could continuously monitor a patient's heart activity, providing valuable insights into heart health.

๐Ÿซ€What it is:
A Holter monitor is a nifty device used in healthcare to keep a close eye on a person's heart. It's like a mini-computer that you wear & it records your heart's activity for an extended period, typically 24 to 48 hours, or even longer.

A Holter monitor is like a heart surveillance device that helps doctors get a better understanding of what's going on inside your ticker over a longer period. It's a valuable tool in keeping our hearts healthy.

๐Ÿซ€How it works:
Small, sticky patches with wires, called electrodes, are placed on your chest. These electrodes are connected to the Holter monitor, which you can carry in a pocket or wear around your neck. As you go about your daily activities, the monitor quietly does its job, recording every heartbeat.

๐Ÿซ€Why is this important?
It helps doctors detect irregular heart rhythms or issues that might not show up during a short visit to the clinic. It's like having a heart detective with you, observing your heart's behavior over an extended period.

Once the monitoring period is over, you return the Holter monitor to the healthcare provider, who then analyzes the data. They can spot any irregularities, like arrhythmias or skipped beats, which can be crucial in diagnosing heart problems.

What is Corrective Maintenance?

This is any type of maintenance that we do AFTER a failure has occurred.

Many people mistake it for โ€œbreakdown maintenanceโ€.

But really, there are 2 types of Corrective Maintenance:

1๏ธโƒฃ Emergency maintenance is when something URGENTLY needs fixing that it breaks into our frozen weekly schedule. This is something weโ€™re all too familiar with. Something we want to avoid at all costs.

2๏ธโƒฃ Deferred corrective maintenance on the other hand, are other tasks that are more stable. Minor equipment faults or conditions that don't immediately impact plant availability... but need to be addressed in the future. These can often be Planned. Scheduled. Prioritised.

Don't mistake these two with each other.

Because the majority of your corrective maintenance should be deferred.

๐–๐ก๐š๐ญ ๐ข๐ฌ ๐๐ซ๐ž๐ฏ๐ž๐ง๐ญ๐ข๐ฏ๐ž ๐Œ๐š๐ข๐ง๐ญ๐ž๐ง๐š๐ง๐œ๐ž?

I know this is a really basic question.

But many organisations fail to answer this correctly.

Because when most people talk about preventive maintenance...

They actually refer to Time Based Maintenance (TBM).

When in fact, it's only one out of five basic types of Preventive Maintenance:

Time-Based Maintenance (TBM)

Failure Finding Maintenance (FFM)

Risk-Based Maintenance (RBM)

Condition-Based Maintenance (CBM)

Predictive Maintenance (PDM)

This distinction is important because an effective PM program should use all of these different types of PMs.

Many organisations rely too much on TBM then say โ€œHey, weโ€™re doing Preventive Maintenanceโ€.

So to answer the question: What is Preventive Maintenance?

Preventive Maintenance is NOT Time-based Maintenance.

It is any maintenance focused on PREVENTING or mitigating the consequences of equipment failure so thatโ€”

-our equipment is available when we need it

-our equipment does what it's supposed to do

-we achieve this safely and with optimum cost.

A preventive maintenance task is a task we do before a failure has occurred. That task can be aimed at preventing a failure, minimising the consequence of the failure, or assessing the risk of the failure occurring.

Bubble CPAP, or continuous positive airway pressure, is a noninvasive respiratory support modality used to manage newborns with respiratory distress. It provides continuous pressure that helps prevent derecruitment of alveoli, increasing the lungs' functional residual capacity, and thus decreasing the work of breathing.

Bubble CPAP works by using a heated and humidified gas source to deliver a constant pressure to the infant's airway through nasal prongs. The pressure is created by a water column in the expiratory limb of the circuit. The depth of the water column determines the level of pressure.

To set up a bubble CPAP system, you will need the following supplies:

* A bubble CPAP machine
* A heated and humidified gas source
* Nasal prongs
* A water reservoir
* A tubing set

Once you have gathered your supplies, follow these steps to set up the system:

1. Connect the heated and humidified gas source to the bubble CPAP machine.
2. Attach the nasal prongs to the end of the tubing set.
3. Immerse the expiratory limb of the tubing set in the water reservoir. The depth of the water column will determine the level of pressure.
4. Turn on the bubble CPAP machine and adjust the pressure to the desired level.
5. Apply the nasal prongs to the infant's nostrils and secure them in place.

Once the system is set up, monitor the infant closely for signs of respiratory distress, such as increased respiratory rate, grunting, and retractions. If you observe any of these signs, contact the infant's healthcare provider immediately.

Bubble CPAP is a safe and effective treatment for newborns with respiratory distress. It can help to improve lung function, reduce the work of breathing, and prevent complications such as pneumonia and chronic lung disease.

Here are some additional tips for using bubble CPAP:

* Make sure the nasal prongs are properly fitted to the infant's nostrils. This will help to prevent leaks and ensure that the infant is receiving the correct amount of pressure.
* Monitor the infant's temperature closely. Bubble CPAP can cause the infant to lose heat, so it is important to keep them warm.
* Be sure to clean and sterilize the tubing

Let's talk about Quality control (QC)

A) Definition/Importance
โ€ข QC is a statistical process used to monitor and evaluate the analytical process that produces patient results
โ€ข Ensures reproducibility of the testing system (precision) and accuracy
โ€ข Helps to detect changes in performance of the testing system
โ€ข Helps to verify that the patient results released are reliable
โ€ข It is testing of known samplesย with known concentrations

B) QC resultsย 
โ€ข can be quantitative (a number), qualitative (positive or negative) or
semi-quantitative (a qualitative result that is based on a quantitative measurement-a
cut-off value to distinguish positive from negative results. A sample concentration at or above the cut-off value is reported as positive and a sample concentration less than the cut-off value is reported as negative.)

C) Characteristics of QC Product (material)
โ€ข A QC product is a patient-like material
โ€ข Can be made from human serum, urine, whole blood, spinal fluid etc.
โ€ข Can be liquid or lyophilized(freeze-dried)
โ€ข Can be assayed or unassayed
โ€ข It is composed of one or more constituents(analytes) of known concentration.
โ€ข It should be tested in the same manner as patient samples.

D) Quality Control Testing
โ€ข Good laboratory practice requires testing normal and abnormal controls.
โ€ข Each lab should evaluate QC levels(number), frequency and rules depending on their policies.
โ€ข QC testing must comply with CLIA requirements, accreditation agencies, state and local health departments, and manufacturer's recommendations.

E) QC Frequency
โ€ข The decision on QC frequency is influenced by multiple factors.
โ€ข The Clinical and Laboratory Standards Institute (CLSI) states in its guidelines that the criteria should be based on:
-Expected stability of the system
-Number of patient specimens routinely analyzed
-Cost of reanalysis caused by QC failure
-Workflow patterns
-Operator characteristics
-Clinical impact of an undetected error that may occur before the next control is run
-Stability of the analyte in patient specimens
-Timing of reagent lot change
-Following calibration
-Detection of questionable patient results

But wait!!!

What do you think?

Is this correct? Or very wrong?

What did you do?

Did you change jobs frequently (letโ€™s say every 3-5 years) or stayed long at one job/company.

Would love to get your feedback on this very important topic.

Extra Corporial Membrane Oxygenation
A life support machine that replaces the function of the heart and lungs. These patients are the sickest of all patients in any critical care unit and will invariably have a prolonged course and rehabilitation

When the heart cannot pump blood and the lungs cannot provide enough oxygen or take out the carbon dioxide.

It pumps blood from the patient's body to an artificial lung which adds oxygen to it and further removes carbon dioxide and it further pumps the blood back to the patients body just like the heart does which is done via a centrifugal pump.

Generally no. Patients that undergo ECMO are typically already connected to a ventilator through a breathing tube down their mouth or nose and have received pain medications and sedatives. When they're first connected to the machine, they are sedated and do not feel the tubes going into their veins and arteries. And when his or her condition improve they will not need it any longer as their heart and lungs start to function normally again.

Yes. But very rare only in specialised centres and through careful patient selection. Awake ECMO is ECMO without mechanical ventilation in spontaneously breathing patients. They are maintained awake during ECMO run. It is usually used for patient with acute respiratory distress.

It varies based on the depth of the injury and the seriousness of the patients condition. ECMO does NOT cure the disease. It is only a support mechanism when the patient undergoes the treatment /recovery phase.

An ECMO is similar to the HLM which is used during bypass surgeries . But an ECMO is used for longer period like hours , days or even weeks based on the recovery pace of the patient. Where as a HLM is used only during the surgery.
